hay
A ranked grep for coding agents: exactly ripgrep’s matches, reordered so the declaration comes first.

$ trace "hay"
- agent transcripts
- ripgrep matches
- declaration priors
- paired evaluation
The problem
Plain grep is prior-free: it ranks a dead plan-v3-FINAL.md exactly like the function definition. Measured over 2,508 real agent searches across 71 repositories, the answer landed in the top ten only 34–62% of the time, whatever the repo hygiene.
The constraint
Same matches, same flags, same path:line:text output as rg. No index, no daemon, no state — and every claim pre-registered against a transcript-derived test collection before shipping.
The approach
ripgrep’s engine and walk plus declaration and path priors. Seven ranking signals were designed; four earned nothing in ablation and were deleted. Every miss has a counted category in a published error taxonomy.
The outcome
Paired over 951 queries (0.2.0): MRR 0.258 → 0.458, answer in top ten 44.9% → 77.1% (95% CI excludes zero). Still worse on 115 of those queries (12%) — the README says so. Started as a repo-hygiene score that predicted nothing; the negative result is published beside the tool.

AGENTS / TOOLING
Skills
Ten skills for AI coding agents, one install: isolated code review, independent verification before "done", model routing with resumable Codex lanes, a bounded audit pass, codebase readiness scoring, spaced-repetition teach-back, audience-calibrated explanations, an expert stress test, a handoff prompt for a second agent’s independent review and mobile screen concepts.
