Adds a new bundled extension that proactively checks and refreshes AWS
credentials for Bedrock model users.
Startup (session_start):
- Runs 'aws sts get-caller-identity' with the profile extracted from
the configured awsAuthRefresh command
- If credentials are expired, runs the refresh command (e.g. aws sso login)
before the user sends their first prompt
- Shows 'AWS Bedrock login confirmed ✓' when credentials are valid
Mid-session (before_provider_request):
- Re-verifies credentials every 15 minutes before Bedrock API calls
- Catches credential expiry during long sessions without needing retry logic
Zero changes to base files — the entire feature is a single extension file.
Only activates when awsAuthRefresh is set in settings.json and the current
model uses bedrock-converse-stream.
* refactor: replace MCPorter CLI with native MCP client using @modelcontextprotocol/sdk
MCPorter is a third-party global CLI that fails to install on many systems,
producing error noise on every startup. Replace it with a native extension
that uses the already-bundled @modelcontextprotocol/sdk Client class directly.

* docs: update README extension table from MCPorter to MCP Client

* fix: add .js suffix to MCP SDK subpath imports for NodeNext resolution
The SDK wildcard export (./*) requires .js suffix for TypeScript NodeNext
module resolution. Also add .js-suffixed virtual module keys so jiti
resolves them correctly in compiled Bun binaries.

Add missing \u1680 (Ogham space mark) to UNICODE_SPACES in path-utils.ts
and loader.ts. Make edit-diff.ts import the shared constant from
path-utils.ts instead of maintaining an inline copy.
Rename hashlineParseText to parseHashlineText to follow the parseX()
convention used across the codebase.

* fix: prevent data loss on crash with atomic writes, file locking, and error handling
Wave 1 of failure recovery safeguards:
1. Atomic session file rewrites (tmp+rename) — _rewriteFile() and forkFrom()
now use atomicWriteFileSync to prevent session file corruption on crash
2. Atomic auto.lock writes — crash-recovery.ts writeLock() uses tmp+rename
so the crash detection system itself can't be corrupted
3. unhandledRejection handler — catches silent process death from unhandled
promise rejections in OAuth, extensions, LSP, or MCP connections
4. try/catch in emitToolCall — matches pattern used by emitUserBash,
emitContext, and emitToolResult to prevent extension handler crashes
from killing the entire agent turn
5. File locking on session appends — prevents concurrent pi instances from
interleaving partial JSON lines in session JSONL files using the same
proper-lockfile pattern established in auth-storage.ts and settings-manager.ts
* fix: add OAuth timeouts, RPC exit detection, and command context guards
Wave 2 of failure recovery safeguards:
1. OAuth fetch timeouts — all fetch() calls across all OAuth providers
(Anthropic, OpenAI Codex, Google Antigravity, Google Gemini CLI,
GitHub Copilot) now have 30-second AbortSignal.timeout() to prevent
indefinite hangs when OAuth servers are unresponsive
2. RPC subprocess exit detection — pending requests are now rejected
when the agent subprocess exits unexpectedly, preventing indefinite
hangs in the RPC client
3. Extension command context guards — default handlers for newSession,
fork, navigateTree, switchSession, and reload now throw explicit
errors instead of silently returning success when called before
bindCommandContext()
4. OAuth error detail preservation — token refresh errors now preserve
the original error as `cause` for better diagnostics
* fix: resource cleanup, LSP retry, and crash detection on session resume
Wave 3 of failure recovery safeguards:
1. Atomic completed-units.json cleanup — milestone completion writes
now use tmp+rename pattern for consistency with auto-recovery.ts
2. Bash temp file cleanup — track temp files created for large output
and register a process exit handler to clean them up
3. Settings write queue flush on shutdown — call settingsManager.flush()
during interactive mode shutdown so queued writes aren't lost
4. LSP initialization retry — wrap getOrCreateClient with up to 2 retries
with exponential backoff (1s, 2s) for transient spawn failures
5. Crash detection on session resume — wasInterrupted() checks if last
assistant turn had tool calls without results, shows warning on resume
* fix: blob garbage collection and LSP debug logging
Wave 4 of failure recovery safeguards:
1. Blob garbage collection — BlobStore.gc(referencedHashes) removes
orphaned blobs not referenced by any session file, plus totalSize()
for monitoring blob directory growth
2. LSP JSON parse error logging — malformed LSP messages are now logged
at debug level (when DEBUG env is set) instead of being silently dropped
- Fix loadStoredEnvKeys divergent provider lists: add telegram_bot and
custom-openai to wizard.ts (the canonical copy used by CLI), remove
dead duplicate from onboarding.ts
- Security: add SAFE_COMMAND_PREFIXES allowlist to resolveConfigValue
to prevent arbitrary RCE via settings.json shell commands
- Security: add TOFU (Trust On First Use) model for project-local
extensions — skip untrusted .pi/extensions/ with stderr warning
- Performance: debounce sql.js MemoryStorage persistence (500ms window)
so rapid mutations coalesce into a single db.export()+writeFileSync
- Fix double lstatSync call in tool-bootstrap.ts isRegularFile
- Add 26 new tests covering all changes
* feat: allow extensions to use 'yaml' and rework frontmatter parsing
* feat: add run-hook command for manual hook execution
* fix: sanitize slashes in unitType for runtime file paths
Add "success" to notify type union across ExtensionUIContext, interactive
mode, and RPC mode implementations. Fix null safety for readFileSync and
contextUsage.percent in auto.ts. Add discriminated union narrowing for
dispatch results. Add string type guards for select() return values in
commands.ts. Align ProviderErrorPauseUI notify signature. Simplify
AuthStorage return type.

* docs: add startup performance analysis and optimization plan
Profiled GSD CLI startup finding 2.2s for --version and ~3.8s for
interactive mode. Identified 5 root causes with measured timings and
created a phased optimization plan targeting <0.2s for --version
and ~0.8s for interactive startup.
* perf: speed up GSD startup with lazy loading and fast paths
- Fast-path --version/-v and --help/-h in loader.ts before importing
any heavy dependencies (2.2s → 0.15s, 14x faster)
- Lazy-load undici (~200ms) only when HTTP_PROXY env vars are set
- Skip initResources cpSync when managed-resources.json version
matches current GSD version (~128ms saved per launch)
- Lazy-load Mistral SDK (~369ms) on first API call instead of startup
- Lazy-load Google GenAI SDK (~186ms) on first API call instead of
startup
- Parallelize extension loading with Promise.all() instead of
sequential for-loop

GitHub Copilot users with Claude models got 400 errors because the native
Anthropic web_search_20250305 tool was injected into requests to Copilot's
API proxy, which doesn't support it. The root cause was that model_select
never fires before the first API request on new sessions, so the fallback
heuristic (model name starts with "claude-") couldn't distinguish direct
Anthropic from proxied providers.
Fix: pass the resolved Model object through to the before_provider_request
event so extensions can check model.provider directly instead of relying on
model name heuristics.
In RPC mode, `ctx.ui.custom()` returns `undefined as never`, causing
`showInterviewRound` to return undefined and `Object.keys(result.answers)`
to throw TypeError.
When `showInterviewRound` returns undefined (RPC mode), fall back to
sequential `ctx.ui.select()` calls for each question, forwarding the
abort signal (#171) and supporting `allowMultiple` (#165).
- Add `allowMultiple` to `ExtensionUIDialogOptions`
- Widen `select()` return type to `string | string[] | undefined`
- Add `allowMultiple` to RPC select request and `values` array to response
- Update RPC `select()` to forward `allowMultiple` and parse array responses
- Guard existing `ctx.ui.select()` callers against the widened return type

External packages (pi-rtk, pi-context, pi-agent-browser, etc.) import from
the original @mariozechner/* scope which GSD forked to @gsd/*. Add aliases
in both jiti resolution paths (virtualModules for Bun, getAliases for Node)
so these packages resolve correctly without manual workarounds.
Closes#161

Vendor all 4 Pi packages (tui, ai, agent-core, coding-agent) from
pi-mono v0.57.1 as @gsd/* workspace packages under packages/. This
replaces the compiled npm dependency (@mariozechner/pi-coding-agent)
and patch-package workflow, giving direct source access for
modifications.
- Copy Pi source from pi-mono v0.57.1 into packages/
- Create workspace package.json + tsconfig.json for each package
- Rename ~240 imports from @mariozechner/pi-* to @gsd/pi-*
- Apply existing patches as source edits (setModel persist, VT input)
- Remove @mariozechner/pi-coding-agent dep and patch-package
- Update build pipeline to build packages in dependency order
- Add pi-upstream git remote for future selective syncing
