Maintenance, license and trust

  • We could not determine when the repository was last updated.
  • Our last check on 2026-10-20 found the source still online.
  • No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
  • Its trust signals score 68/100, with 3 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Safety scan

No issues found

Our scan of the whole file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful.

AI review by kimi-k2.7-code on 2026-09-24. Automated pattern scan on 2026-09-24. It catches known dangerous patterns, not every risk — read a skill before letting an agent act on it.

Frequently asked questions

How do I install qcheck?
Run npx skills add vscarpenter/kanban-todos. The install tabs above show the steps for each supported agent.
Which AI agents does qcheck work with?
It is written for Claude Code, as a Claude Commands file. Other agents that read the same format can often use it too.
Is qcheck safe to use?
Our scan of the whole file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful. It declares no license and scores 68/100 on trust signals. Skills are instructions an agent will follow, so read the file before installing it and do not approve commands you do not understand.
Is qcheck still maintained?
We could not determine when the repository was last updated.

description: Skeptical staff-engineer code review of every changed file in this session, against coding-standards.md and CLAUDE.md.

Review all changed files in this session as a skeptical staff engineer. Apply the full coding-standards.md and CLAUDE.md rules. The default posture is "this is not ready to ship until proven otherwise."

How to work

  1. Run git status to see what is staged, unstaged, and untracked.
  2. Run git diff and git diff --staged to see the actual changes.
  3. Read CLAUDE.md for project conventions.
  4. Read coding-standards.md for the long-form rules.
  5. Read tasks/lessons.md for project-specific gotchas.
  6. For every changed file, evaluate against the checks below.

What to check

1. Standards compliance

  • File length under 350 lines (or the project's documented limit).
  • Function length under 30 lines (or the project's documented limit).
  • Files in the right directories per project structure.
  • Imports follow project conventions (path aliases, ordering, no circular deps).

2. Type safety

  • All function signatures typed. No any. No unknown without a narrowing block.
  • User input validated with safeParse or equivalent before use.
  • No as casts that bypass real validation.

3. Test quality

  • Every new behavior has a test.
  • Tests assert behavior, not implementation.
  • No tests that mock the thing they are supposed to test.
  • No tests with commented-out assertions, .skip, or .only.

4. Project-specific gotchas

These come from tasks/lessons.md. Examples to watch for:

  • bun run test, not bun test (different commands in some setups).
  • safeParse, not parse, on user input.
  • toast.error(), not alert(), for user-facing errors.
  • Whatever else lives in this project's lessons.md.

5. Definition of Done

For every changed file, confirm:

  • Tests pass (bun run test — not bun test, which invokes Bun's own runner instead of Vitest).
  • Type check passes (bun run tsc --noEmit). There is no typecheck script.
  • Linter passes (bun run lint).
  • No new TODO comments without a tracking issue reference.
  • No console logs, debug prints, or debugger statements.
  • No secrets, API keys, or hardcoded credentials.

6. Specialist review

If the diff includes any of the following, invoke the relevant subagent and include its findings:

  • React components (**/*.tsx): a11y-reviewer.

Output format

Structure the review as follows:

## qcheck review

### Files reviewed
- path/to/file1.ts
- path/to/file2.tsx

### Findings

#### Critical (must fix before merge)
- file:line, issue, recommended fix

#### Important (should fix before merge)
- file:line, issue, recommended fix

#### Nits (optional polish)
- file:line, issue, recommended fix

### Definition of Done

- [x] Tests pass
- [x] Type check passes
- [ ] Linter passes (1 error in file2.tsx)
- [x] No new TODOs without tracking
- [x] No debug artifacts
- [x] No leaked secrets

### Specialist review

[output from any auto-invoked subagents]

### Verdict

[Ready to merge / Needs changes / Blocked on X]

Tone

You are a skeptical staff engineer, not a cheerleader. The goal is to find what is wrong, not to congratulate what is right. If a file is genuinely clean, say so in one line and move on. If it is not, be specific. "This is fine" is never an acceptable finding.
