 ## Release process: build artifacts and create a draft GitHub release
-Use this process when preparing a Cassady (`cass`) release. Always create the GitHub release as a **draft** first; do not publish the final release unless the user explicitly asks.
+Use this process when preparing a Cassady (`cass`) release. Prefer the GitHub Actions release workflow over local cross-builds so macOS/Linux/Windows assets are built on runners instead of by hand. Always create the GitHub release as a **draft** first; do not publish the final release unless the user explicitly asks.
 ### 0. Preferred automated release workflow
 The release workflow is `.github/workflows/release.yml`. On a pushed `v*` tag it builds and uploads draft GitHub release assets automatically. For an existing tag or to publish the release/npm packages, run it manually:
 ```sh
 gh workflow run release.yml \
  --repo owenqwenstarsky/cassady \
  -f tag="$TAG" \
  -f replace_assets=true \
  -f publish_github_release=false \
  -f publish_npm=false
 ```
 Set `publish_github_release=true` only when the user explicitly asks to publish the GitHub release. Set `publish_npm=true` only when the user explicitly asks to publish npm packages, and make sure the `NPM_TOKEN` repository secret exists first. The workflow deletes/replaces old release assets, uploads the four current archives/checksums, and publishes npm packages from those runner-built archives.
 Keep release notes in `docs/releases/${TAG}.md` when the workflow should apply curated notes. If that file is missing, the workflow falls back to generated placeholder notes.
 Use the manual steps below only for local debugging or when the workflow cannot be used.

 Do **not** publish the draft or mark it as the final/latest release unless the user explicitly asks.
 ## NPM package process: prepare and publish the binary packages
 Use this process when preparing Cassady for npm. The npm distribution is a tiny wrapper package plus platform-specific binary packages. Do not publish to npm unless the user explicitly asks; when they ask for a publish-ready setup, make sure the packages can be published with one command.
 ### Package layout and names
 The committed npm tooling generates packages under `dist/npm/` from the current Rust version in `Cargo.toml`:
 - Wrapper package: `cassady`
  - Exposes both npm binaries: `cass` and `cassady`.
  - `cass desktop` launches the bundled desktop binary when the installed platform package includes one.
  - Depends on the platform packages through `optionalDependencies` at the exact same version.
 - Platform packages:
  - `@cassady/cli-darwin-arm64` for `aarch64-apple-darwin`
  - `@cassady/cli-linux-x64` for `x86_64-unknown-linux-gnu`
  - `@cassady/cli-linux-arm64` for `aarch64-unknown-linux-gnu`
  - `@cassady/cli-win32-x64` for `x86_64-pc-windows-gnu`
 Before the first publish, make sure the npm account owns or has publish access to the `cassady` package name and the `@cassady` scope. If the npm package name or scope changes, update `npm/scripts/lib/release-config.mjs` and regenerate the packages. Scoped packages are published with `--access public`.
 ### 1. Build the release binaries first
 Prefer the `.github/workflows/release.yml` workflow with `publish_npm=true`; it rebuilds release assets on runners, rehydrates the npm package inputs from those archives, and publishes with `NPM_TOKEN`. For manual publishing, the npm packages copy binaries from the release build outputs, so run the same verification and target builds used for the GitHub release first. macOS/Linux packages include `cassady-desktop` so `cass desktop` works from npm installs; Windows remains CLI-only for now.
 ```sh
 cargo +stable test --locked --all-targets
 cargo +stable build --release --locked --target aarch64-apple-darwin

 (cd cassady-desktop && cargo tauri build --target aarch64-apple-darwin)
 # Linux desktop binaries built with `cargo tauri build` on Linux/Tauri builders, as in the GitHub release process.
 ```
 ### 2. Generate and verify the npm package directories
 ```sh
 npm run npm:prepare
 npm run npm:verify
 ```
 `npm:prepare` rebuilds `dist/npm/` for the current `Cargo.toml` version. `npm:verify` runs `npm publish --dry-run` for each generated package and does not publish anything.
 ### 3. Publish to npm when explicitly requested
 The publish command prepares packages, checks npm auth, runs `npm login` if needed, checks whether each package version already exists, publishes platform packages first, publishes the wrapper last, and verifies that the published versions can be packed from npm. The existence/verification checks intentionally use `npm pack --dry-run` instead of `npm view` because npm registry metadata for newly-created scoped packages can briefly return 404 even after publish succeeds.
 ```sh
 npm run npm:publish
 ```
 Optional checks and controls:
 ```sh
 npm run npm:publish -- --dry-run   # full publish flow without publishing
 NPM_TAG=next npm run npm:publish    # publish under a non-latest dist-tag
 ```
 If a version already exists, npm cannot overwrite it. Stop and ask before changing versions, deleting packages, or moving dist-tags.

 Cassady (`cass`) is a terminal coding agent written in Rust. It runs an interactive chat in your project, can inspect files, apply exact edits, run shell commands when the active safety mode allows them, and persist sessions for later resume. Cassady talks to OpenAI-compatible providers and a built-in ChatGPT Codex provider preset.

 ## Tool output and context recovery
 Cassady keeps tool calls reviewable while fitting provider context windows. Very large tool results may be sent to the model as compacted or truncated head/tail excerpts with a note that names the tool, retained excerpt shape, file ranges or command provenance when available, and suggested follow-up reads/searches. Treat those notes as incomplete evidence: ask Cass to re-read a narrower line range, run a focused `grep`, or rerun a narrower shell command before editing from omitted details.

 # Cassady (Cass) Roadmap
 ## v0.4.2 — Desktop Slash Commands
 This release focuses on full slash-command support in the desktop app and on moving the command system out of the CLI into a shared core module so the TUI and the desktop share one registry, parser, autocomplete, and execution path. The desktop composer now surfaces a filterable slash menu with auto-run, and the interactive commands (`/login`, `/logout`, `/branch`) open native modals. See `plans/DESKTOP_SLASH_COMMANDS_PLAN.md`.
 ### Shared Command Core
 - [x] **Add the `cassady::commands` module.** Move the command catalog (`COMMANDS`/`CommandSpec`), `LocalCommand`/`FastModeCommand` enums, `parse`, the autocomplete builders (`build_autofill` + `command_autofill`/`model_autofill`/`resume_chat_autofill`), and the pure action functions out of `src/app.rs` into a new public core module.
  - Move `AutoFillItem`/`AutoFillMenu` from `ui/autofill.rs` into `commands` (with serde derives); `ui/autofill` re-exports them so the TUI renderer is unchanged.
  - Add `CommandOutcome`/`CommandContext`/`execute` as the single entry point both hosts use; interactive commands return `Open*Picker` outcomes so each host renders its own picker.
 - [x] **Refactor the CLI dispatcher onto the shared module.** Replace the inline `match parse_local_command` block and the private helpers in `src/app.rs` with `commands::execute` + an outcome match; delete the duplicated code. CLI user-facing behavior is unchanged.
 - [x] **Expose `embedding::Session` accessors.** Add `config`/`config_mut`/`conversation`/`set_conversation` and refactor `Session::set_model` to delegate to `commands::apply_model_selection`, removing the duplicated resolve/switch logic.
 ### Desktop Slash Surface
 - [x] **Add a slash-command popup to the composer.** `SlashMenu` reuses the `ModelSelector` pattern (filter, arrow-key nav, grouped headers, click-outside) and auto-runs complete commands on selection; value-command names insert and keep the menu open for argument selection. Typing a complete command and pressing Enter also runs it.
  - Add Tauri commands `list_slash_commands`, `slash_autofill`, `run_slash_command`, plus `create_branch_from_checkpoint`, `apply_provider_login`, `discover_models`, `remove_providers`, and `list_provider_catalog`, with camelCase DTOs and TS mirrors.
 - [x] **Route command outcomes in the desktop shell.** `/fast`, `/status`, and `/model` push status blocks and update the status footer; `/new` and `/resume` install the new conversation and rebuild the transcript (including resume warnings); busy/parse/error outcomes update the status line.
 ### Interactive Command Modals
 - [x] **Add a branch/restore modal.** `BranchModal` lists the branch family, supports switching to a branch or branching from a checkpoint (conversation-only or with tracked-file restore), and reports the restore outcome in the transcript.
 - [x] **Add a logout modal.** `LogoutModal` multi-selects configured providers, removes them via `remove_providers`, refreshes the model list, and reports the result.
 - [x] **Add a login wizard modal.** `LoginModal` picks a provider from the catalog, configures base URL / API-key env / model id, and applies via `apply_provider_login`.
 ### Verification
 - [x] **Build, test, and document.** `cargo test --locked --all-targets`, `cargo fmt --check`, `cargo clippy` (no new warnings), the desktop `npm run typecheck` and `npm run build` all pass. Update `docs/commands.md` to note desktop parity.
 ## v0.4.0 — Desktop App
 This release focuses on adding a native desktop app for Cassady that runs the real coding agent via the experimental Rust embedding API, themed to match the `cassady-web/` landing page. The desktop app is a peer of the TUI: same config, providers, tools, safety policy, and JSONL storage, with a windowed chat surface for streaming transcripts, tool calls, approvals, and cancellation. See `plans/V0_4_0_DESKTOP_APP_PLAN.md`.
 ### Workspace Setup
 - [ ] **Add the `cassady-desktop` workspace member.** Convert the root `Cargo.toml` to a Cargo workspace with `members = ["cassady-desktop"]` while keeping the existing `cassady` package at the repo root.
  - Depend on `cassady` via a path dependency; embed through the public `cassady::prelude` API only.
  - Do not modify `src/` (the existing lib, bins, or TUI).
 ### Design System Port
 - [ ] **Port the landing-page design system into the desktop frontend.** Copy `cassady-web/src/index.css` (tokens, scanlines, grain, vignette, glow utilities) and IBM Plex `@fontsource` setup into the Tauri frontend.
  - Reuse `cass-logo-transparent.png` for the app icon and in-app branding.
  - Copy the shadcn `ui/` primitives (button, card, separator, tooltip, accordion) so chrome matches the landing page.
 ### Chat Surface
 - [ ] **Build the streaming chat UI.** Composer, transcript with full markdown rendering for assistant text, tool-call blocks for `read`/`write`/`edit`/`shell`/`grep`/`ls`, reasoning toggle, and a terminal-style status footer.
  - Stream events over `tauri::ipc::Channel<StreamEvent>` from a per-turn Rust worker that drives `Session`/`Turn`/`Event`.
  - Approve or deny `ApprovalRequested` events through a native dialog; cancel running turns with `Turn::cancel`.
 ### Session Lifecycle
 - [ ] **Make desktop and CLI sessions interoperable.** New chat, resume by id, and list chats for the current cwd all use the same `~/.cass/conversations/*.jsonl` storage.
  - A chat started in the desktop app is resumable from `cass --resume <id>`, and a CLI-started chat is openable in the desktop app.
  - Show a "run `cass setup` first" card when `~/.cass` has no valid provider config; a setup-wizard GUI is deferred.
 ### Verification
 - [ ] **Build, test, and document the desktop app.** `cargo build -p cassady-desktop`, `npm run tauri build`, and a manual smoke test across new chat, streaming, approval, cancel, and resume interop.
  - Add Rust tests for `StreamEvent` mapping and `SessionBuilder` round-trip against a temp `config_root`.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass across the workspace.
 ## v0.3.5 — Tool Output Context Reliability ✅ Completed
 This release focuses on making large tool outputs easier for the assistant to recover from when model-context compaction or truncation hides important details. Cassady should guide the assistant toward smaller, targeted reads and searches, preserve enough provenance for follow-up inspection, and add regression coverage for broad-output workflows that previously stalled safe edits. See `plans/V0_3_5_TOOL_OUTPUT_CONTEXT_RELIABILITY_PLAN.md`.
 ### Model Context Recovery
 - [x] **Improve compacted tool-output guidance.** Replace generic head/tail compaction notices with actionable guidance that tells the assistant what was omitted and how to inspect it again safely.
  - Include tool name, output size, retained excerpt shape, and suggested narrower follow-up reads or searches when available.
  - Keep model-facing guidance concise enough that it does not worsen context pressure.
 - [x] **Preserve targeted reinspection metadata.** Track enough structured context for large reads and command output so the assistant can recover omitted details without repeating broad requests.
  - For file reads, preserve path and line-range coverage even after compaction.
  - For shell and search output, prefer guidance toward narrower commands or `grep`/`read` follow-ups rather than blindly rerunning the same broad command.
 ### Tool Behavior and Prompting
 - [x] **Bias tool use toward smaller inspections.** Update tool descriptions, prompt guidance, and result messages so broad reads become a fallback rather than the default.
  - Encourage search-first workflows for large files and unknown locations.
  - Mention result limits before or at truncation points so the assistant knows when context may be incomplete.
 - [x] **Make truncation and compaction visible across layers.** Align model-facing messages, stored conversation records, and UI summaries so users and the assistant can tell when output was incomplete.
  - Do not let UI-only collapsed output change what is stored or sent to the model.
  - Keep existing conversation files readable and resumable.
 ### Validation
 - [x] **Add regression coverage for broad-output recovery.** Test workflows where an early broad read or command output is compacted before the assistant needs exact context for an edit.
  - Cover superseded reads, compacted non-newest tool outputs, provider-message validity, and suggested follow-up guidance.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.3.4 — Reasoning Off Handling ✅ Completed
 This release focuses on sending the correct reasoning effort value when a reasoning-capable model has reasoning turned off. Cassady now sends `none` rather than omitting the field or sending `off` to both the ChatGPT Codex Responses API and OpenAI-compatible chat completions, while non-reasoning models continue to send no reasoning field at all.
 ### Reasoning Effort Off
 - [x] **Send `none` when reasoning is off for supported models.** For reasoning-capable models with reasoning effort set to off, send `none` as the effort value instead of omitting the field or sending `off`.
  - Apply to the ChatGPT Codex Responses API (`reasoning.effort`) and OpenAI-compatible chat completions in both `reasoning_effort` and `reasoning` object request formats.
  - Keep non-reasoning models sending no reasoning field.
 - [x] **Gate reasoning fields on model capability.** Track whether the active model supports reasoning from its metadata so reasoning request fields are only added for reasoning-capable models.
 ### Validation
 - [x] **Add regression coverage for reasoning-off requests.** Test that supported models send `none` when reasoning is off across both provider kinds and both request formats, and that unsupported models send no reasoning field.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.3.3 — Codex Fast-Mode Compatibility ✅ Completed
 This release focuses on keeping fast mode available for ChatGPT Codex users when local model metadata predates the fast-mode capability flag. Cassady should treat active `chatgpt-codex` provider models, including `gpt-5.5`, as fast-capable while leaving OpenAI-compatible and custom providers capability-gated by model metadata.
 ### Fast Mode Compatibility
 - [x] **Treat ChatGPT Codex models as fast-capable at runtime.** Make `/fast` active for any active `chatgpt-codex` provider model even when legacy `models.json` metadata says `fast_mode.supported` is false.
  - Keep non-Codex providers governed by their model metadata.
  - Preserve the saved fast-mode preference behavior and status reporting.
 - [x] **Document the Codex capability fallback.** Update README and bundled docs so users understand that ChatGPT Codex models, including `gpt-5.5`, can honor fast mode without refreshed metadata.
  - Keep docs clear that provider-specific fast-mode request shaping remains Codex-only.
 - [x] **Add regression coverage for legacy metadata.** Test that a ChatGPT Codex model with older `fast_mode.supported: false` metadata still reports fast mode as supported and active when preferred.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.3.2 — Provider Fast Mode ✅ Completed
 This release focuses on adding a `/fast` command that lets users prefer faster inference when the active provider/model supports it. The first supported provider is `ChatGPT Codex`; other providers can add their own fast-mode request behavior later without changing the user-facing command. See `plans/V0_3_2_FAST_MODE_PLAN.md`.
 ### Fast Mode Command
 - [ ] **Add a persisted `/fast` preference.** Let users toggle fast mode from an idle chat and keep that preference across sessions.
  - Store the preference in `config.json` without disturbing provider/model configuration.
  - Keep the preference separate from whether the current provider/model can honor it.
 - [ ] **Show capability-aware fast-mode status.** Display fast mode as enabled only when the active provider/model supports it.
  - If the user switches to an unsupported provider/model, hide the enabled state and report fast mode as unavailable when relevant.
  - If the user switches back to a supported provider/model, apply the existing preference again.
 ### Provider Support
 - [ ] **Implement ChatGPT Codex fast-mode requests.** Add the provider-specific request option for Codex when fast mode is active.
  - Verify and test the exact Codex responses request shape during implementation.
  - Do not send Codex-specific fast-mode fields to OpenAI-compatible providers.
 - [ ] **Add extensible provider/model capability metadata.** Model fast-mode support as provider/model metadata so future providers can opt in case by case.
  - Default unknown and custom providers to unsupported.
  - Mark built-in ChatGPT Codex model metadata as supported when Cassady can send the fast-mode request.
 ### Documentation and Validation
 - [ ] **Document fast mode behavior and limits.** Update README and bundled docs for `/fast`, `default_fast_mode`, model capability metadata, and Codex-only initial support.
  - Explain the difference between a saved fast-mode preference and active fast-mode support.
 - [ ] **Test fast-mode preference, switching, and provider requests.** Cover command parsing, persistence, status rendering, model/provider switching, and Codex request body behavior.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.3.1 — Transcript Scroll Stability ✅ Completed
 This release focuses on keeping the live transcript anchored correctly above the input and footer during long sessions with blank reasoning or tool-output lines.
 ### TUI Reliability
 - [x] **Fix bottom-scroll row counting for whitespace-only lines.** Count indented blank transcript rows the same way Ratatui renders them so accumulated blank rows no longer hide recent transcript content above the footer.
  - Add regression coverage for whitespace-only wrapped row counting.
 ## v0.3.0 — ChatGPT Codex Provider ✅ Completed
 This release focuses on letting users who are already signed in to Codex with a ChatGPT subscription use that account from Cassady. `ChatGPT Codex` becomes a provider preset that calls the Codex responses endpoint and reads its bearer token from local Codex auth instead of an API-key environment variable. See `plans/V0_3_0_CHATGPT_CODEX_PROVIDER_PLAN.md`.
 ### Provider Setup
 - [x] **Add a ChatGPT Codex provider preset.** Make `ChatGPT Codex` available from `cass login`, `/login`, and first-run setup as a distinct provider option.
  - Use provider id `chatgpt-codex` and endpoint `https://chatgpt.com/backend-api/codex/responses`.
  - Skip the normal API-key environment-variable prompt for this preset.
  - Prefer the model configured in local Codex config when available, with manual model entry as a fallback.
 - [x] **Read local Codex auth safely.** Resolve the bearer token from `$CODEX_HOME/auth.json` or `~/.codex/auth.json` at check/request time.
  - Support the local Codex `tokens.access_token` shape without copying the token into `~/.cass`.
  - Give clear recovery steps when the user has not run `codex login`, signed in to the Codex app, or has an expired/missing token.
 ### Provider Runtime
 - [x] **Add a ChatGPT Codex responses client.** Route `chatgpt-codex` providers to the exact Codex responses endpoint instead of the OpenAI-compatible `/chat/completions` path.
  - Translate Cassady messages, tools, tool calls, and tool outputs to the endpoint's expected responses format.
  - Stream assistant text, safe reasoning summaries when available, and function-call deltas back into the existing agent loop.
 - [x] **Keep OpenAI-compatible providers unchanged.** Refactor provider dispatch only as much as needed to support the new provider kind.
  - Existing provider config, setup, model discovery, API-key env vars, `/model`, and `cass check` behavior should continue to work.
  - Avoid leaking ChatGPT access tokens in errors, logs, transcripts, or config files.
 ### Documentation and Validation
 - [x] **Document ChatGPT Codex prerequisites and caveats.** Update README and bundled docs for setup, config examples, `cass check`, troubleshooting, and the distinction between ChatGPT subscription-backed access and API-key providers.
  - Make clear that Cassady uses an existing Codex login and does not implement its own browser login or token refresh flow in this release.
  - Note that the ChatGPT backend endpoint may change outside Cassady's control.
 - [x] **Test Codex auth and provider behavior.** Cover Codex auth fixtures, config validation, setup catalog behavior, provider dispatch, streaming response parsing, tool calls, and secret redaction.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.2.9 — Provider Login Management ✅ Completed
 This release focuses on making provider configuration available from both the shell and an active Cassady chat. Users can add or update OpenAI-compatible provider/model settings with `cass login` or `/login`, and remove saved providers and their associated models with `cass logout` or `/logout`. See `plans/V0_2_9_PROVIDER_LOGIN_MANAGEMENT_PLAN.md`.
 ### Login Commands
 - [x] **Add login commands for provider setup.** Make `cass login` and `/login` open the provider setup flow so users can configure providers without remembering that setup is the underlying implementation.
  - Reuse the existing provider catalog, model discovery, model capability prompts, and safe JSON writes.
  - Keep `/login` idle-only and reload active provider/model config after the menu closes.
 - [x] **Keep existing setup behavior intact.** Preserve `cass setup` and first-run setup while making login language feel natural for account/provider management.
  - Direct `cass login` should save configuration and exit rather than unexpectedly starting a chat.
  - Existing setup validation and missing API key guidance should continue to apply.
 ### Logout Commands
 - [x] **Add a safe provider removal menu.** Make `cass logout` and `/logout` let users choose saved providers to remove from `providers.json`.
  - Remove associated `models.json` entries for selected providers.
  - Confirm the removal before writing changes.
 - [x] **Repair active defaults after removal.** Ensure `config.json` never points at a provider/model that was just removed.
  - Select a valid remaining provider/model when possible.
  - Clear active provider/model defaults when no providers remain so the next startup offers login/setup.
 ### Documentation and Validation
 - [x] **Document provider login and logout workflows.** Update command, configuration, and workflow docs with the new shell and in-chat commands.
  - Clarify that logout removes Cassady provider config, not environment variables or external provider accounts.
 - [x] **Test provider management behavior.** Cover provider/model removal, active default repair, local command parsing, and autocomplete.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before handoff.
 ## v0.2.8 — Conversation Branch and Restore ✅ Completed
 This release focuses on making conversation recovery safe and explorable. Pressing `Esc` twice while idle opens a branch/restore menu where users can browse prior user messages, assistant messages, and tool calls, create a new branch from a selected checkpoint, and optionally restore Cassady-tracked file edits without destroying the original conversation. See `plans/V0_2_8_CONVERSATION_BRANCH_RESTORE_PLAN.md`.
 ### Branch Navigation
 - [x] **Open a branch/restore menu with double Esc.** Add an idle `Esc`-twice shortcut that mirrors the discoverability of double `Ctrl-C` while preserving current busy-turn cancellation and approval-denial behavior.
  - Keep draft input intact when the menu is opened or cancelled.
  - Provide clear status text after the first `Esc` so users know a second press opens branch/restore.
 - [x] **Browse checkpoints across the related branch family.** Show user messages, assistant messages, tool-call requests, and tool results from the current chat and related branches.
  - Include enough preview text, tool names, paths, timestamps, and branch labels to choose the right point.
  - Allow switching back to the original conversation or another existing branch from the same menu.
 ### Safe Conversation Branching
 - [x] **Create branches instead of destructive reverts.** Selecting a checkpoint should write a new conversation JSONL with parent/checkpoint metadata, leaving the source conversation unchanged.
  - Support repeated branching so users can return to the menu later and branch or switch again.
  - Keep older conversations without branch metadata loadable.
 - [x] **Handle tool-call checkpoints cleanly.** Branching at a specific tool call or tool result should preserve a valid provider message history.
  - Repair partial multi-tool assistant turns with synthetic cancelled/omitted tool results where needed.
  - Add tests for branching at user, assistant, and tool boundaries.
 ### File Edit Restoration
 - [x] **Journal Cassady file edits with restorable snapshots.** Record successful `write` and `edit` tool mutations outside the model-visible transcript with before/after hashes and snapshots.
  - Keep restore support limited to Cassady-tracked file tools; warn that shell commands and manual edits are not automatically reversible.
  - Store enough data to restore both backward and forward between tracked checkpoints.
 - [x] **Offer explicit conversation-only or conversation-plus-files restore actions.** Make conversation-only branching the safe default, and require confirmation before changing workspace files.
  - Preview files to update or delete, detect hash conflicts, and refuse unsafe overwrites by default.
  - Use atomic writes for restored files and preserve clear status/transcript messages for skipped or conflicted paths.
 ### Documentation and Validation
 - [x] **Document branch/restore workflows and limitations.** Update README and bundled docs with the double-`Esc` shortcut, menu controls, branch semantics, and file-restore safety model.
  - Include troubleshooting for restore conflicts and unsupported shell/manual filesystem changes.
 - [x] **Test the branch and restore model.** Cover branch metadata, checkpoint extraction, tool-call repair, edit journaling, restore planning, and keybinding behavior where practical.
  - Verify `cargo fmt` and `cargo test --locked --all-targets` pass before release.
 ## v0.2.7 — Self-Update Command
 This release focuses on making Cassady easy to keep current after installation. The goal is to let users run one clean command, `cass update`, to check GitHub releases, choose the recommended prebuilt binary or a source-build fallback, verify what will be installed, and update both `cass` and `cassady` safely. See `plans/V0_2_7_SELF_UPDATE_COMMAND_PLAN.md`.
 ### Update Command Experience
 - [x] **Add a polished `cass update` command.** Check the official Cassady GitHub releases, compare the running version to the selected release, and guide the user through an interactive update flow.
  - Keep update independent of provider/model setup so it works even when config is missing or invalid.
  - Support script-friendly checks with flags such as `--check`, `--dry-run`, and `--yes`.
 - [x] **Select the right update path.** Prefer a matching prebuilt release archive when available, with explicit `--prebuilt` and `--source` modes for users who want to choose.
  - Support the same macOS, Linux, and Windows targets used by Cassady releases.
  - Offer source builds for unsupported targets or users who prefer building locally.
 ### Safe Installation
 - [x] **Verify and stage prebuilt artifacts before replacing binaries.** Download archives and SHA-256 files from the release, verify checksums, extract safely, and validate staged `cass`/`cassady` binaries.
  - Reject checksum mismatches, unsafe archive paths, missing binaries, and unexpected versions.
  - Show clear progress and failure messages without dumping raw implementation details.
 - [x] **Replace installed binaries cleanly.** Update the current binary and same-directory companion binary when possible, using backups and rollback on failure.
  - Do not auto-run `sudo` or administrator prompts.
  - Handle Windows executable replacement with a staged helper or documented manual fallback if necessary.
 ### Source Build Fallback and Documentation
 - [x] **Build from release source when requested.** Download the selected release source, validate its version, check for Rust tooling, run a locked release build, and install the resulting local binaries.
  - Keep source mode tied to release tags rather than arbitrary branches.
  - Do not attempt cross-compilation or Rust toolchain installation in this release.
 - [x] **Document and test update behavior.** Update README and bundled docs for `cass update`, platform notes, troubleshooting, and package-manager caveats.
  - Add tests for release parsing, target mapping, asset selection, checksum validation, archive extraction safety, install planning, and mocked update flows.
 ## v0.2.6 — Rust Embedding API ✅ Completed
 This release focuses on adding the first intentional Rust library surface for embedding Cassady in other Rust projects. The goal is to provide the bones for programmatic, headless agent sessions: configure a workspace, start or resume an agent session, send turns, stream typed events, and handle approvals without launching the TUI. See `plans/V0_2_6_RUST_EMBEDDING_API_PLAN.md`.
 ### Experimental Public API
 - [x] **Add a supported embedding module.** Provide a small `cassady::embedding` API with builder, session, turn, event, approval, and error types so callers do not need to stitch together internal modules directly.
  - Mark the API experimental for v0.2.6 rather than promising long-term semver stability.
  - Keep existing CLI/TUI behavior unchanged while steering library users toward the new module.
 - [x] **Support host-configured agent sessions.** Let Rust callers create or resume headless sessions with explicit cwd, access mode, model/provider overrides, reasoning effort, and Cassady config root.
  - Reuse existing config files, global instructions, bundled docs, security policy, and JSONL conversation storage.
  - Avoid requiring callers to construct CLI-specific types.
 ### Headless Turn Execution
 - [x] **Run agent turns programmatically.** Add a Tokio-native API for sending one user message, streaming assistant/tool/status events, and returning the updated session or conversation state.
  - Prevent or clearly reject overlapping turns unless the type design makes them impossible.
  - Preserve provider streaming, tool execution, prompt generation, and context behavior from the existing agent loop.
 - [x] **Expose approval handling to host applications.** Allow embedded callers to approve or deny tool approval requests, especially shell commands in `workspace-edit` mode.
  - Include request id, tool call id, tool name, arguments, and reason in approval events.
  - Document cancellation/drop behavior for active turns.
 ### Documentation and Validation
 - [x] **Add a minimal headless example.** Include a compilable Rust example that imports Cassady, starts a session, sends a prompt, and prints streamed assistant output.
  - Note that a configured OpenAI-compatible provider and API key are still required.
  - Show where to handle approval requests even if the first example defaults to `read-only`.
 - [x] **Document the experimental Rust API.** Add bundled docs and README links for setup requirements, basic usage, event handling, approvals, limitations, and current non-goals.
  - Make clear that multi-agent orchestration, custom providers, custom tools, daemons, and stable plugin APIs are deferred.
 - [x] **Test embedding without a terminal.** Add integration tests that use temporary config/conversation roots and mock provider responses to verify session creation, turn streaming, resume, approval flow, and access-mode behavior.
  - Ensure `cargo test --locked --all-targets` covers the new public API and examples.
 ## v0.2.4 — System Prompt Refinement
 This release focuses on making Cassady's system prompt clearer, more intuitive, and more useful for everyday coding work without letting it become bulky. The target is a well-structured prompt around 1,000 tokens that gives the model enough product context, safety expectations, and workflow guidance to behave consistently across read-only, workspace-edit, and full-access sessions. See `plans/V0_2_4_SYSTEM_PROMPT_REFINEMENT_PLAN.md`.

 # Security Policy
 ## Supported Versions
 Security updates are provided for the latest released version of Cassady. If you are using an older version, please upgrade to the latest release before reporting an issue, unless the issue also affects the latest release.
 | Version | Supported |
 | ------- | --------- |
 | Latest | ✅ |
 | Older releases | ❌ |
 ## Reporting a Vulnerability
 Please do **not** report security vulnerabilities in public GitHub issues, discussions, or pull requests.
 To report a vulnerability, use GitHub's private vulnerability reporting for this repository:
 1. Open the repository on GitHub.
 2. Go to **Security** → **Report a vulnerability**.
 3. Include as much detail as you can about the issue, impact, affected versions, and steps to reproduce.
 ## What to Include
 Helpful reports include:
 - A description of the vulnerability and likely impact.
 - Steps to reproduce or a minimal proof of concept.
 - The Cassady version, operating system, shell, and terminal environment.
 - Relevant configuration details with secrets removed.
 - Any known mitigations or workarounds.
 Do not include live API keys, tokens, private prompts, or sensitive project files in a report. Redact secrets before sharing logs or configuration.
 ## Response Expectations
 After a report is received, the maintainer will aim to:
 - Acknowledge the report within 7 days.
 - Confirm whether the issue is in scope and reproducible.
 - Provide status updates when there is meaningful progress.
 - Coordinate disclosure timing before publishing details publicly.
 Security fixes may be released as patch versions when appropriate. Public disclosure should wait until a fix or mitigation is available, unless otherwise coordinated with the maintainer.
 ## Scope
 Examples of in-scope issues include vulnerabilities in Cassady that could:
 - Bypass documented access modes, approval prompts, or workspace boundaries.
 - Cause unintended file reads, writes, edits, or shell command execution.
 - Leak API keys, provider credentials, chat history, or local configuration.
 - Corrupt or expose session data stored under `~/.cass`.
 - Introduce unsafe behavior in bundled release artifacts.
 Out-of-scope issues generally include:
 - Vulnerabilities in third-party model providers or APIs not controlled by this project.
 - Prompt-injection behavior that does not bypass Cassady's documented safety controls.
 - Issues that require a compromised local machine, shell, dependency cache, or provider account.
 - Reports against unsupported older versions that are fixed in the latest release.
 ## Safe Harbor
 Good-faith security research is welcome. Please avoid privacy violations, data destruction, service disruption, and accessing data that does not belong to you. If you follow this policy and make a good-faith effort to avoid harm, the maintainer will not pursue legal action for your research.

 # Cassady Desktop
 Cassady Desktop is the v0.4.0 desktop preview. It uses the same Cassady config, providers, tools, approval policy, and `~/.cass/conversations/*.jsonl` sessions as the terminal CLI.
 ## Launch from a release archive
 macOS and Linux release archives include three binaries:
 - `cass`
 - `cassady`
 - `cassady-desktop`
 Keep them in the same directory or put all three on `PATH`, then launch the desktop app with:
 ```sh
 cass desktop
 ```
 `cass desktop` starts `cassady-desktop` as a detached background process, so you can close the terminal after the window opens. For debugging, keep it attached with:
 ```sh
 cass desktop --foreground
 ```
 If the desktop binary is somewhere else, set:
 ```sh
 CASSADY_DESKTOP_BIN=/path/to/cassady-desktop cass desktop
 ```
 Run `cass setup` first if Cassady has no configured provider.
 ## Development
 From the repository root:
 ```sh
 cd cassady-desktop
 npm install
 cargo tauri build --target aarch64-apple-darwin --no-bundle -- --locked
 ```
 `cargo tauri build` runs the frontend build and embeds the generated assets into the standalone binary. Release Cargo builds now fail fast when `cassady-desktop/dist` is missing or incomplete, and `cass desktop` rejects desktop binaries that do not contain the bundled frontend assets. A plain debug `cargo build -p cassady-desktop` is useful for Rust checks, but do not package that output.
 For a GUI dev session, run the Vite dev server and the Tauri app using your local Tauri workflow. Release packaging uses the raw `cassady-desktop` binary, not DMG, app bundle, AppImage, MSI, or other installer artifacts.

owen	ab0c45aff4	Correct roadmap: real v0.3.4 release notes, rename planned Tool Output Context Reliability to v0.3.5 The v0.3.4 tag is the released 'Reasoning Off Handling' release (commit `b35c4fb`), distinct from the planned Tool Output Context Reliability work. Add proper v0.3.4 release notes based on the shipped commit, move the Tool Output Context Reliability entry to the top as v0.3.5, and rename its plan file to match.	2026-06-25 21:56:44 -05:00
owen	b35c4fb7e1	Send reasoning effort 'none' when reasoning is off CI / Build (push) Waiting to run CI / Test (push) Waiting to run When a reasoning-capable model has reasoning effort set to off, send 'none' rather than omitting the field or sending 'off'. This applies to both the ChatGPT Codex Responses API and OpenAI-compatible chat completions (both reasoning_effort and reasoning object formats). Non-reasoning models continue to send no reasoning field at all. Bumps version to 0.3.4.	2026-06-25 20:08:15 -05:00
