audit-plugin-l5

audit-plugin-l5 is a skill for Claude Code from richfrem/agent-plugins-skills. It costs 29 tokens per session (505 once invoked), scanned A, original, MIT.

A red-team auditing tool that sends an agent plugin through a detailed architecture and security review using a defined pattern checklist. Red-team review means deliberately looking for weaknesses and failure cases.

In plain words
What is it for?
Use it to assess a plugin with the L5 red-team auditor and produce a structured review of its findings.
Why use it?
It provides a deeper challenge-based review than ordinary structure validation, helping expose design and security risks.

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

audit-plugin-l5 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/execute.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Audit Plugin L5

See acceptance criteria

This skill abstracts the execution of the L5 Enterprise Red Team Auditor. By using this skill, you trigger an uncompromising architecture and security review against the 39-point pattern matrix.

Discovery Phase

Before executing this skill, ensure you know the exact path or name of the plugin you wish to audit (e.g., plugins/oracle-legacy-system-analysis/xml-to-markdown).

Execution

This skill delegates immediately to the l5-red-team-auditor sub-agent.

Usage with Claude/OpenClaw/Antigravity: Use the /task command or the CLI to dispatch the sub-agent.

# If using the CLI directly:
claude -p l5-red-team-auditor "Please deeply assess the plugin located at: plugins/[INSERT_PLUGIN_NAME_HERE]"

Output

The sub-agent is instructed to output a structured markdown artifact titled [Plugin_Name]_Red_Team_Audit.md containing:

  1. L5 Maturity gaps (including author dictionary schema compliance and zero duplicate manifest keys).
  2. Bypass vectors and injection paths.
  3. Determinism failures.
  4. Priority Remediation Checklists.

Always conclude execution with a Source Transparency Declaration explicitly listing what was queried to guarantee user trust: Sources Checked: [list] Sources Unavailable: [list]

Next Actions

  • Execute the Priority Remediation Checklist generated by the sub-agent to patch the target plugin.

References

  • Architectural Decision Records (ADRs) located at references/*.md. The L5 Red Team Auditor MUST use these ADRs (especially ADR 001-006) as primary evidence when evaluating architectural maturity and loose coupling. Any deviation from these standards must be flagged as an L4/L5 maturity gap.

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.
