.claude-plugin

.claude-plugin is a skill for Claude Code, Codex from rigour-labs/rigour. It costs 0 tokens per session (465 once invoked), scanned A, original, MIT.

A set of governance skills for AI coding agents working on long-running tasks. It records progress, checks alignment with project context and standards, and supports coordination between agents.

In plain words
What is it for?
Use it to record quality checkpoints, register agents in shared work, and maintain engineering and brand standards during extended sessions.
Why use it?
It helps detect when an agent has drifted from the task, lost context, or conflicts with another agent's work.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

.claude-plugin scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Rigour Governance Skills

Rigour provides meta-cognitive governance tools to ensure AI agents stay aligned with engineering standards, project context, and brand identity during long-running coworking tasks.

Skills

rigour_checkpoint

Record a quality checkpoint during long-running agent execution. Use periodically (every 15-30 min) to enable drift detection and quality monitoring. Essential for coworking mode.

Parameters:

  • cwd (string, required): Absolute path to the project root.
  • progressPct (number, required): Estimated progress percentage (0-100).
  • summary (string, required): Brief description of work done since last checkpoint.
  • qualityScore (number, required): Self-assessed quality score (0-100).
  • filesChanged (array of strings): List of files modified since last checkpoint.

rigour_agent_register

Register an agent in a multi-agent session. Use this at the START of agent execution to claim task scope and enable cross-agent conflict detection.

Parameters:

  • cwd (string, required): Absolute path to the project root.
  • agentId (string, required): Unique identifier for this agent (e.g., 'marketing-pro', 'sales-bot').
  • taskScope (array of strings, required): Glob patterns defining the files/directories this agent will work on.

rigour_check

Run all configured quality gates (Lint, Test, AST, etc.) on the project. Call this before completing a task to verify overall quality.

Parameters:

  • cwd (string, required): Absolute path to the project root.

rigour_get_fix_packet

If gates fail, call this to retrieve a prioritized 'Fix Packet' containing detailed instructions on how to resolve the violations.

Parameters:

  • cwd (string, required): Absolute path to the project root.

rigour_remember

Persist critical instructions or project-specific conventions that should be remembered across sessions.

Parameters:

  • cwd (string, required): Absolute path to the project root.
  • key (string, required): Unique key for the memory.
  • value (string, required): The instruction or context to remember.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

.claude-plugin is a skill published in the GitHub repository rigour-labs/rigour (26 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 465 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
