Claude Skills by jjanczur

Drive a real browser and come back with a MEASUREMENT rather than an impression - console errors and >=400 responses as counts, computed styles as JSON when appearance is disputed. Use when work touches UI, when a review must verify one, or when fidelity-gate asks for its measurement.

The depth half of a review - the dimensions a diff is read against (correctness, boundaries, concurrency, failure paths, secrets, data access, structure, test quality) and the rule that a finding is refuted before it is reported. The verdict stays with the reviewer agent. Use when reviewing a diff or a pull request, or when asked about N+1 queries or wasted round trips.

The optimization pass, defined - delete before you add, one smell class per pass, behaviour pinned by a test that ran BEFORE the edit. Lints a SKILL.md and prose by the same instinct. Use for the per-story optimization pass or when code has grown noisy without growing capable.

Check that Tyran itself is healthy in this repo - gates that cannot fire, journal and projection drift, orphaned leases, dead policy rules, config that fails its schema. Reports findings with the fix for each. Use for /tyran:doctor or when a gate seems not to be working.

Build a UI against a frozen visual reference without drift - an inventory extracted before any code, a relics list, and a gate that MEASURES computed styles on a fixture carrying the reference's own data. Use when a mockup, design spec or screenshot is the contract.

Smoke-test skill that verifies the Tyran plugin is installed and namespaced correctly. Invoke with /tyran:hello.

Work a reviewer's comments on a pull request to the end - all three comment surfaces enumerated before any is triaged, every comment fixed, declined with a reason, or ticketed, push before you reply. Use when a PR comes back with review feedback or a red check.

Tune a prompt, or anything whose quality is measured by non-deterministic model output, without chasing noise - a noise baseline before the first edit, medians over repeated runs, enforcement AFTER generation rather than in the wording. Use when iterating on prompts or model-judged output.

Close an initiative by learning from it - spawns the retrospective agent over the ledger, the notes and the agents' reports, records what changed and what was rejected, and writes durable repo facts into .tyran/knowledge/. Runs at the end of an initiative; also available as /tyran:retro.

Find the mechanism behind a failure instead of patching its symptom - reproduce first, one variable per experiment with the prediction written before the run, exit by naming the mechanism and pinning it with a failing test. Use for a bug, an unexplained red test, or a failure that will not reproduce.

Conduct a task end to end, from a one-line fix to a multi-day programme - a short interview, then autonomous execution to the finish. Classifies the task S/M/L/XL, configures itself to the repo, routes each role to a cost tier, drives the agent team from the kanban board, and stops only at genuine decisions. Use for /tyran:run or when asked to carry something "all the way" or "with a team of agents".

Configure Tyran for this repository. Scans the stack, the validation commands and the git history, writes .tyran/config.yaml with provenance for every inferred value, installs the bare /tyran shortcut, and asks you only about what it genuinely could not establish. Run once per repo.

How a skill earns its place here and how it is written so it fires - a three-question admission test, one protocol per skill, the description priced against the CI budget, and an activation test from a cold session. Use when the retrospective proposes a new skill or rewrites one.

Where is the work right now. Regenerates the projections and the kanban board from the journal and answers with the progress line, the agents still running, the open gates and the resume steps. Read-only. Use for /tyran:status or when asked what is going on.

Conduct a task end to end with Tyran - interview, plan, delegate to a team of fresh-context agents, verify with evidence, merge. Use for /tyran or when asked to carry something all the way through.
