gap-trap — Gated Quality Framework for Agent-Written Code

Installs and refines a repo quality framework where every agent rule names a gate that fails a commit, push, or CI run.

Dev & CodingAdvanced★ 181⑂ 9AI score 9/10Last updated: Oct 2, 2026

What it does

  • Discovers the repo (stack, test/lint commands, CI provider, contract candidates using real symbol names), shows a single plan for confirmation, then executes.
  • Writes the instruction layer (AGENTS.md, AGENTS.project.md, CLAUDE.md, agents/) from templates and migrates existing rules from .cursorrules, copilot-instructions.md, and CONTRIBUTING.md row by row — nothing is dropped silently.
  • Builds the actual gates in your test runner and CI: instruction-file gate, proven-red tests, PR body check, ratchet counters, and a mutation smoke for risky modules; each gate is proven red with a scratch violation, then committed as one logical change at a time.
  • refine mode audits rules without gates, contracts pointing at symbols that no longer exist, and recent history, proposing the next rules and gates as a single PR — and deletes rules with no incident behind them.

Who it's for

  • Teams and solo devs whose coding agents (Claude Code, Codex) write most of the code
  • Anyone tired of written-but-ignored project rules and wanting mechanical enforcement
  • Users who can edit pre-commit hooks and CI, and who run a top-tier model (Opus-class)

Examples

  1. gap-trap setup — bootstrap contracts, gates, hooks, and CI in a repo that has none.
  2. gap-trap refine — after the first incident, derive the next rule and gate from what actually broke.
  3. "gate the rules" / "make the agents' code match the rules" — convert prose rules in an existing AGENTS.md into ID'd rules with named gates.

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the gap-trap folder from the GitHub repo pliablepixels/gap-trap into my ~/.claude/skills/gap-trap/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/pliablepixels/gap-trap.git /tmp/gap-trap && cp -r /tmp/gap-trap/gap-trap ~/.claude/skills/ && rm -rf /tmp/gap-trap

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo to a temp folder: git clone https://github.com/pliablepixels/gap-trap.git /tmp/gap-trap
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy the skill in: cp -r /tmp/gap-trap/gap-trap ~/.claude/skills/
  5. Clean up: rm -rf /tmp/gap-trap
  6. Restart Claude Code — skill lists are loaded at session start.
  7. Switch to a top coding model with /model (Opus-class); on cheaper tiers the skill refuses to run by design.
  8. In your target repo, ask for gap-trap setup or gap-trap refine. Work on a branch: the skill commits changes and edits hooks and CI config.
