a11y-pass

01

Archive228/loopkit

Skill Claude CodeCodex

Catch the accessibility failures that ship in almost every AI-built UI. Use after building any interactive component.

Archive228/loopkit

Skill Claude CodeCodex

Before compaction Loopkit extracts decisions into claude-decisions.json (machine-readable). Read it alongside claude-progress.txt at session start — prose is for humans, JSON is for the loop.

adversarial-verify

03

Archive228/loopkit

Skill Claude CodeCodex

Review a diff against the goal spec assuming the code is BROKEN. The reviewer that lives in the maker's head always agrees with itself — this pulls review into a hostile, separate pass. Invoke after every code change before marking work done.

authz-check

04

Archive228/loopkit

Skill Claude CodeCodex

Verify that an endpoint checks ownership, not just authentication. Use on any handler that reads or mutates user data.

bisect-regression

05

Archive228/loopkit

Skill Claude CodeCodex

Find the exact commit that introduced a bug. Use when something worked before and broke, and you don't know which change did it.

broken-window-check

06

Archive228/loopkit

Skill Claude CodeCodex

Before picking new work, smoke-test the last "completed" feature. If it's broken, revert and re-open it before touching anything else. Kills the "looks shipped, isn't shipped" bug across sessions.

changelog-from-diff

07

Archive228/loopkit

Skill Claude CodeCodex

Turn a set of commits or a diff into a clean, user-facing changelog entry. Use before a release or PR description.

clean-commits

08

Archive228/loopkit

Skill Claude CodeCodex

Turn messy WIP into clean, atomic commits with messages that explain why. Use before opening a PR.

context-budget

09

Archive228/loopkit

Skill Claude CodeCodex

Keep the agent's context lean so accuracy doesn't collapse. Use on long sessions, big files, or when the agent starts hallucinating.

contract-test

10

Archive228/loopkit

Skill Claude CodeCodex

Test the boundary between two systems by the contract, not the implementation. Use for APIs, integrations, and shared interfaces.

coverage-gaps

11

Archive228/loopkit

Skill Claude CodeCodex

Find the untested code paths that actually matter, not just the coverage percentage. Use after adding tests.

decision-record

12

Archive228/loopkit

Skill Claude CodeCodex

Capture an architectural decision so the next session (or engineer) knows WHY. Use after any non-obvious technical choice.

dependency-audit

13

Archive228/loopkit

Skill Claude CodeCodex

Decide whether to add, keep, or remove a dependency. Use before adding any package.

design-system

14

Archive228/loopkit

Skill Claude CodeCodex

Make frontend output look intentional, not AI-generated. Use for any UI work — components, pages, layouts.

eval-harness

15

Archive228/loopkit

Skill Claude CodeCodex

Build a repeatable eval loop that grades agent output with an LLM judge, so prompt/skill changes get scored against a baseline instead of eyeballed. Reuses loopkit's verifier subagent as the grader — do not build a new one.

753 +2 1mo ago A 54 tokens original MIT

Archive228/loopkit

Skill Claude CodeCodex

Calibrate a reviewer persona with few-shot rubric examples so skepticism stays consistent and doesn't drift lenient over long runs.

feature-list-json

17

Archive228/loopkit

Skill Claude CodeCodex

Enumerate every end-to-end feature as strict JSON entries with passes:false, editable-passes-only discipline, and priority order. The ledger fresh-context sessions read to know what's done, what's next, and what they're forbidden to touch.

flaky-hunter

18

Archive228/loopkit

Skill Claude CodeCodex

Diagnose and fix tests that pass sometimes and fail other times. Use when CI is red intermittently.

harness-stripping

19

Archive228/loopkit

Skill Claude CodeCodex

Systematically remove one harness component at a time and measure impact, killing scaffolding that no longer earns its complexity.

hitl-escalate

20

Archive228/loopkit

Skill Claude CodeCodex

Escalate blocked runs to a human via configured channel or fallback to BLOCKED.md and exit the loop. Use when the loop hits an ambiguous spec, a missing credential, a destructive action needing approval, or 3+ consecutive verify failures on the same task.

753 +2 1mo ago A 59 tokens original MIT

Archive228/loopkit

Skill Claude CodeCodex

Author idempotent init.sh under 120s plus sibling test.sh, stop.sh, reset.sh, serve.sh with fixed names the harness relies on.

input-validation

22

Archive228/loopkit

Skill Claude CodeCodex

Validate and constrain untrusted input at the boundary. Use on any handler that accepts external data.

kill-dead-code

23

Archive228/loopkit

Skill Claude CodeCodex

Find and remove unreachable/unused code safely. Use during cleanup or before a refactor.

Archive228/loopkit

Skill Claude CodeCodex

Design the three states every data UI forgets. Use for any component that fetches or lists data.
