performance

Measurement-first optimization that refuses to report what the data does not support. go-faster sweeps the whole process for evidenced ways to go faster. target ranks candidates by evidence quality. goal sets realistic and ideal targets and computes the floor first. snapshot captures interleaved baseline and post runs on a qualified host and refuses wall-clock claims from a noisy one. verify re-derives results in a fresh context. protect locks in a counter win with a CI ceiling.

Skills (7)

  • climb

    Keep-or-revert loop on a frozen harness: one hypothesis and one commit per attempt, both arms re-measured every time, kept by a rule written before the first attempt, logged outside the tree, in its own worktree and branch. Use when: 'keep trying changes until this counter drops', 'hill-climb this b

  • go-faster

    Background sweep of the whole AI-assisted development process (this session's work, git, hooks, the rest of the setup) for ways to go faster without losing accuracy, returning evidenced findings ranked by measured size and speedups to adopt now; edits no repository file or setting. Use when: 'go fas

  • goal

    Performance goal the data can settle: metric, command, realistic and ideal targets, and the floor computed before any work, surfacing 'your target is below the measured floor, no code change can reach it' up front. Human-gated, never unattended. Use when: 'set a performance target', 'is this target

  • protect

    Checked-in CI ceiling on the counter of a performance win /performance:verify reported MET: a regression fails the build and a lower count proposes a lower ceiling by PR. Proposes files; a human approves and merges. Use when: 'protect this win', 'ratchet this counter', 'stop this regressing', 'add a

  • snapshot

    Capture a baseline or post-change snapshot with the host qualified first: refuse a wall-clock claim from a bimodal-contention host and name the drift-immune counter instead. Interleaves before/after arms in one run. Use when: 'capture a baseline', 'take a post snapshot', 'run the A/B', 'can I even m

  • target

    Ranking of optimization targets by evidence quality, from session pain, a named path or telemetry, so an unmeasured system yields 'instrument this first' instead of a guess. Use when: 'what should we optimize', 'find the bottleneck', 'this feels slow', 'is X worth optimizing'. Skip: a whole-process

  • verify

    Fresh-context re-derivation of a performance result that does not inherit the implementer's numbers, reporting the target as met or not met without rounding a miss into a win. Use when: 'verify this speedup', 'is this result real', 'independent verification', 'write up the performance result'. Final

  • go-faster-sweeper

    Runs the /performance:go-faster sweep in a fresh context: checks each area of the development process, writes every finding through findings.py into the run directory it is handed, and returns the report path. Read-only toward the repository and settings. Dispatched by /performance:go-faster; not in

review

claude

Code-review toolkit: nine agents, read-only over the reviewed code, plus orchestration skills for the quality gate and fan-out, a pull-request change digest with an interactive view (/review:explain-change), a merge-risk rating with a demote-only flag (/review:merge-risk), a fan-out sweep workflow (/review:fanout-sweep), and CI lane commands (/review:code-review, /review:security-review) for org reusable workflows.

discipline

claude

Correctors that re-anchor a rule, audit work in flight, and fix drift: do-your-research, follow-our-standards, point-dont-copy, reason-dont-recite, tighten-your-output, recheck-against-upstream, pick-for-the-problem, mind-your-maxims, script-the-deterministic-work, use-your-skills, reuse-or-replace, scrutinize-dont-coast. sweep-all runs them as one batch. wait-what re-pitches a message that did not land. hold-my-hand shows work one phase at a time. be-ambitious raises one request's ambition.

discovery

claude

Discovery before changes: explore the local codebase, run multi-source external research, and reconstruct why a past decision was made from evidence outside the code. Each dispatches a subagent by default so the reading stays out of the main thread, with source tiers, falsification, recency gates and a coverage ledger, and persists EXPLORE.md / RESEARCH.md / INTENT.md handoff artifacts. A research sweep workflow (/discovery:research-sweep) backs deep research with adversarial claim verification.

testing

claude

Test-stage discipline: /testing:plan (coverage gaps, test plans), /testing:write (TDD authoring), /testing:run-e2e (live E2E and smoke checks), /testing:diagnose (failing-test root cause, with a fix-until-green workflow across files), /testing:audit (can't-fail test audit with a fail-closed gate), /testing:cleanup (rewrite, quarantine, or delete low-value tests behind a mutation gate), /testing:setup, and an opt-in hook that flags edits that weaken tests.
