Repro
Turn a vague bug report into a minimal, runnable reproduction. Use when the report is "it crashes sometimes" / "it's broken on some inputs" and the fix needs the smallest script or test that reliably triggers the bug first.
Triage
Triage a repository's issue backlog — dedupe, label, flag missing repro info, draft replies, and rank what's worth fixing. Use when a maintainer faces a pile of open issues and wants order restored without closing things rudely or blindly.
Skeptic
Review a pull request or diff adversarially — by trying to break it with hostile tests rather than reading and approving. Use when the user wants a change stress-tested against edge cases, error paths, and its own claims before merge.
Detox
Hunt down and fix flaky tests. Use when a test suite fails intermittently, CI needs re-runs to go green, or the user wants to know which tests are flaky versus genuinely broken — and why.
Checkup
Give a repository a full health exam — doc rot, dependency staleness, CI decay, git hygiene, dead links, docs contradicting code — and grade it. Use when the user wants to know what quietly rotted, or a prioritized maintenance list.
Declassify
Prepare a private repository for safe open-sourcing. Use when the user wants to make a repo public and needs the secrets sweep (code AND git history), personal-info scrub, license and community files, and a go/no-go checklist.
Bisect
Find the exact commit that introduced a bug or regression using automated git bisect. Use when something used to work and doesn't anymore, and the user wants the guilty commit — especially from a plain-English symptom like "scrolling got janky sometime last month.
Fence
Investigate why a strange piece of code exists before anyone deletes it (Chesterton's fence). Use when the user points at a weird line, hack, magic constant, or workaround and asks why it's there, whether it's still needed, or if it's safe to remove.
Vet
Run a background check on a dependency before installing it. Use when the user is considering adding a package/library and wants to know if it's safe, maintained, appropriately sized, and correctly named — or wants alternatives compared.
Onboard
Test a repository's setup documentation by executing it literally in a clean environment. Use to find where a README's install, build, or run instructions are wrong, outdated, or silently assume undocumented tools, versions, services, or steps.
Semver Cop
Determine whether the next release is legally a patch, minor, or major by diffing the public API surface against the last published version. Use before cutting a release, when reviewing "is this breaking?", or when writing honest release notes.
Necromancer
Resurrect a dead repository. Use when a project no longer installs, builds, or runs because it has aged — broken dependencies, deprecated APIs, dead tooling, registry rot, runtime drift. Revives it incrementally, keeping a verified working state at every step.
