## Summary
- Added `isCompactableTool()` helper in `microCompact.ts` that matches
both the existing COMPACTABLE_TOOLS set and any tool prefixed `mcp__`
- MCP tool results were never compacted because the hardcoded allowlist
only contained 9 built-in tools — MCP tools fell through and persisted
in full for the entire session, wasting 10-500K tokens/session
## Impact
- user-facing impact: long sessions using MCP servers (GitHub, Slack,
Playwright, etc.) will compact stale MCP tool results, reducing token
usage and delaying autocompact triggers
- developer/maintainer impact: new MCP servers are automatically covered
via prefix match — no need to update the allowlist per-server
## Testing
- [x] `bun run build`
- [x] `bun run smoke`
- [x] focused tests: `bun test src/services/compact/microCompact.test.ts`
- module exports load correctly
- estimateMessageTokens counts MCP tool_use blocks
- microcompactMessages processes MCP tools without error
- microcompactMessages processes mixed built-in and MCP tools
## Notes
- provider/model path tested: n/a (compaction logic is model-agnostic)
- screenshots attached (if UI changed): n/a
- follow-up work or known limitations: subagent results and thinking
blocks are still not compacted (separate RFCs)

This pass rewrites comment-only ANT-ONLY markers to neutral internal-only
language across the source tree without changing runtime strings, flags,
commands, or protocol identifiers. The goal is to lower obvious internal
prose leakage while keeping the diff mechanically safe and easy to review.
Constraint: Phase B is limited to comments/prose only; runtime strings and user-facing labels remain deferred
Rejected: Broad search-and-replace across strings and command descriptions | too risky for a prose-only pass
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Remaining ANT-ONLY hits are mostly runtime/user-facing strings and should be handled separately from comment cleanup
Tested: bun run build
Tested: bun run smoke
Tested: bun run verify:privacy
Tested: bun run test:provider
Tested: bun run test:provider-recommendation
Not-tested: Full repo typecheck (upstream baseline remains noisy)
Co-authored-by: anandh8x <test@example.com>
Squash the current repository state back into one baseline commit while
preserving the README reframing and repository contents.
Constraint: User explicitly requested a single squashed commit with subject "asdf"
Confidence: high
Scope-risk: broad
Reversibility: clean
Directive: This commit intentionally rewrites published history; coordinate before future force-pushes
Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr
Not-tested: Fresh clone verification after push
