autoresearch: Command for Claude Code

.opencode/commands/autoresearch_regression.md

autoresearch:regression is a command for Claude Code, OpenCode from uditgoenka/autoresearch. It costs 34 tokens per session (2,480 once invoked), scanned C, a copy of autoresearch:regression, MIT.

A regression-checking command that compares a proposed code change with behavior on an earlier version. It runs the project's own tests, benchmarks, snapshots, or migrations and reports whether the change is stable.

In plain words
What is it for?
Use it to check a branch against a base commit, limit the files examined, choose affected or full test runs, and account for performance noise before shipping.
Why use it?
It catches behavior that worked before but fails after a change. It also makes the comparison explicit before code is pushed.

Command for Claude CodeOpenCode

Written for Claude Code and OpenCode: argument-hint in frontmatter, but also installed under .opencode/.

This is uditgoenka/autoresearch's own configuration. It tells Claude Code and OpenCode how to work on autoresearch itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything autoresearch configures →

About the project

autoresearch is an agent workflow that repeatedly changes a project, verifies a measurable result, keeps or discards the change, and continues iterating toward a goal. It is for autonomous improvement tasks in Claude Code, OpenCode, and OpenAI Codex across domains with mechanical success measures. The catalogue contains its commands, hooks, skills, plugin, agent, and instruction.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

autoresearch:regression scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Verify-command screen (no `rm -rf` / `curl|sh`); worktree cleanup + prune on crash; data-migration refuses any non-allowlisted DB URL; probe auto-skips non-interactively; chained `ship` never auto-deploys.

How it starts

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EXECUTE IMMEDIATELY.

A regression is a green→red transition ONLY. The gate orchestrates the project's OWN test/bench/snapshot/migrate commands (it is a protocol, not a bundled framework), captures baseline behavior in an isolated git worktree, re-runs the candidate, and reports a tiered ship/no-ship verdict.

Parse Arguments

Extract from $ARGUMENTS:

  • Base: or --base — base ref to diff against. Default: git merge-base HEAD main (else main/master).
  • Scope: or --scope — file globs limiting the change surface.
  • --select auto|full|affected — test selection (default auto). auto = use the detected affected-test mapper if available, else FULL suite. Never a silent subset.
  • --samples N — SCORE samples/side (default 7). --noise-band % — perf tolerance (default 5%).
  • --matrix — opt-in matrix axis (OFF by default). --max-runs N — ceiling (default 200).
  • --baseline-cache (default on) — reuse baseline/<full-sha>/ by SHA. Baseline: <prebuilt-ref> — bypass capture.
  • --probe (default) / --probe deep / --no-probe.
  • --predict --reason --debug --fix --fix-cycles N --evals --evals-interval N --chain <targets> and --<sub> shorthand.
  • Iterations: — repeat-axis count for --select/repeat sweeps.

Setup / Probe-on-launch

  1. Auto-detect per-dimension verify commands: package.json scripts, Makefile, nx, migrate config, bench/snapshot/size scripts.
  2. question (single batch) to confirm detected commands + base ref + which dimensions to run.
  3. Auto-skip probe when CI / no-TTY / --mode autonomous / complete-config / chained-handoff — log the inferred config instead of asking.

Classification Phase (first-class, before any differential)

Establish the baseline green-set per dimension, then tag each unit. Match by test-id first, then path.

State Meaning Gated?
regression-eligible green on baseline YES — only green→red counts
pre-existing red→red (already failing) no — excluded
new-coverage absent→red (brand-new test) no — new coverage, ungated
flaky nondeterministic on baseline no — routed to flakiness SCORE
baseline-unavailable dimension never green no — advisory only

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
