Adds scanGitAttributes(repoDir) — pure function that parses
.gitattributes after a sandboxed clone and returns the
{filter,diff,merge} driver entries that would run on checkout. The
clone CLI prints each entry as a "MEDIUM" stderr advisory followed by
a recommendation to verify the smudge/clean command before moving the
clone outside the sandbox.
Why: filter drivers execute arbitrary shell during checkout (smudge
runs on read, clean on write). Even with the existing sandboxed clone,
downstream consumers that re-checkout files outside the sandbox can be
exploited. Surfacing the directive list lets the caller decide whether
to proceed.
Out-of-scope: in-line content of the smudge command is not analysed —
the advisory is for human review, not automatic blocking.
Tests:
- tests/lib/git-clone-gitattributes.test.mjs (8 cases): LFS-style,
custom driver, missing/empty/comment-only files, line-number
tracking, inline-comment stripping, unreadable path graceful return.
Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.
New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.
Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.
Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.
