Recent decisions affecting current work: - Stateless subprocess model (fresh per request, full history replay) - Stream-json control protocol for tool denial (CLI flags cannot achieve "propose but don't execute") - MCP proxy needed for custom tool exposure (replacing SDK's createSdkMcpServer) - Used `any` type for Context parameter to avoid requiring @mariozechner/pi-ai at dev time (01-01) - Separate content-to-text helpers per role for clarity (01-01) - AGENTS.md walk-up resolution with global fallback (01-01) - Used pi-ai's AssistantMessage type directly for event bridge type safety (01-02) - Event bridge parallel array tracking for multi-block content correlation (01-02) - parseLine logs parse failures to console.error for debugging (01-02) - cross-spawn for subprocess spawning (Windows .cmd shim compatibility) (01-03) - Kill-after-result with 2000ms grace period for CLI hang bug (01-03) - Stdin stays open after user message write for future control_response (01-03) - PassThrough streams in provider tests for readline compatibility (01-03) - [Phase 02]: Single-source TOOL_MAPPINGS array with derived lookup maps (02-01) - [Phase 02]: Argument translation renames only known keys, passes through all others (02-01) - [Phase 02]: handleControlRequest takes WritableStream not ChildProcess for testability (02-01) - [Phase 02]: Malformed control_request handled with console.error and return false (02-01) - [Phase 02]: TrackedToolBlock with claudeName field for arg translation at block_stop (02-02) - [Phase 02]: ToolCall.arguments cast via `as ToolCall` to support raw string fallback for parse failures (02-02) - [Phase 02]: TrackedContentBlock.type narrowed to 'text' | 'thinking' for discriminated union support (02-02) - [Phase 02]: Partial JSON parse attempts during delta with graceful fallback (02-02) - [Phase 03]: Added 4 missing tests to close coverage gaps for signature_delta, multi-delta thinking, interleaved thinking+text, and missing usage defaults (03-02) - [Phase 03]: Used --effort levels instead of --thinking-budget tokens (CLI does not support --thinking-budget) (03-01) - [Phase 03]: Opus detection via model.id.includes('opus') for forward-compatibility (03-01) - [Phase 03]: Replaced local StreamOptions with SimpleStreamOptions & { cwd?: string } for type compatibility (03-01) - [Phase 03]: Custom thinkingBudgets trigger console.warn, not error (CLI only supports effort levels) (03-01) - [Phase 04]: Raw JSON-RPC stdio over mcp-schema-server.cjs (no SDK dependency, ~35 lines) (04-01) - [Phase 04]: Break-early kills subprocess with SIGKILL at message_stop before CLI auto-executes tools (04-01) - [Phase 04]: broken flag guards against buffered readline lines after rl.close() (04-01) - [Phase 04]: Control handler allows ALL control_requests (only reached when no break-early) (04-01) - [Phase 04]: fileURLToPath(import.meta.url) for resolving .cjs sibling in ESM/TS module system (04-01) - [Phase 04]: vi.hoisted() for mock references surviving vitest hoisting (04-01) - [Phase 04]: Lazy MCP config via ensureMcpConfig pattern -- defers pi.getAllTools() to first request since it fails at extension load time - [Phase 04]: Custom tool args skip translatePiArgsToClaude in prompt-builder (passthrough, no renames) - [Phase 05]: proc.kill('SIGKILL') is cross-platform safe -- Node.js handles Windows abstraction (05-01) - [Phase 05]: 180-second inactivity timeout covers documented 3+ minute thinking gaps (05-01) - [Phase 05]: endStreamWithError checks both streamEnded AND broken flags (05-01) - [Phase 05]: cleanupProcess grace period reduced from 2000ms to 500ms (05-01) - [Phase 05]: buildPrompt returns string | AnthropicContentBlock[] -- array only when final user message has valid images (05-02) - [Phase 05]: Invalid image blocks fall back to placeholder text, never error (05-02) - [Phase 05]: Module-level placeholderImageCount counter reset per buildPrompt call (05-02) - [Phase 05]: buildCustomToolResultPrompt always returns string, no image passthrough (05-02) - [Phase 05]: writeUserMessage type broadened to string | any[] for image content blocks (05-02) - [Phase 06]: ESLint 9 flat config (not 10) -- npm resolves to 9.39.4; same defineConfig/globalIgnores API (06-01) - [Phase 06]: no-explicit-any disabled globally; 20+ intentional `any` uses across codebase (06-01) - [Phase 06]: no-unused-vars with ^_ ignore pattern for intentionally unused args/vars (06-01) - [Phase 06]: .prettierignore created to exclude package/ directory from formatting (06-01) - [Phase 06]: Coverage thresholds ratcheted from 80/70/80/80 to 92/88/92/92 based on measured baseline (06-01) - [Phase 06]: @vitest/coverage-v8@^3.0.0 pinned to match vitest 3.x peer dependency (06-01) - [Phase 06]: Lint/typecheck on Ubuntu only; tests on 3-OS matrix for CI workflow - [Phase 06]: Tag-triggered publish with shell-based version validation and npm provenance - [Phase 06]: Added .planning/ to .prettierignore to prevent CI failures on planning docs ### Pending Todos None yet. ### Blockers/Concerns - Exact argument mapping schemas need verification against current pi/Claude CLI versions - ~~Image content block handling in stream-json input is undocumented (affects HIST-02 in Phase 5)~~ -- Resolved: implemented image passthrough with Anthropic content block format ## Session Continuity Last session: 2026-03-15T16:12:14.713Z Stopped at: Completed 06-02-PLAN.md Resume file: None
