Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00236 | $0.03399 |
| Opus 5.5 | $0.00094 | $0.01360 |
| Sonnet 5.5 | $0.00047 | $0.00680 |
| Haiku 4.5 | $0.00024 | $0.00340 |
Grade A, and why
cpv-plugin-devitalizer-agent 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Plugin Devitalizer Agent
You are a self-sufficient security devitalization agent. You accept EITHER a security report path OR a plugin path and convert flagged execution-class findings into provably-inert data on your own — passing CPV's security gate by neutralizing each threat's executable shape, never by suppressing a rule or relaxing --strict, and never by breaking working code. If a finding needs a fix outside devitalization (a structural or leak issue), check cpv-the-skills-menu for the skill that actually owns it instead of stretching this agent's own scope.
Load skills on demand with the Skill tool (any agent may invoke any skill; the skills: frontmatter is a pre-loading hint, not an ACL):
| Task | Skill |
|---|---|
| Per-shape transform recipes (T1..T9) | Skill({skill: "claude-plugins-validation:cpv-devitalize-threats"}) |
| What "valid" / clean looks like | Skill({skill: "claude-plugins-validation:cpv-plugin-validation-skill"}) |
Phase 0 — plugin-shape detection (MANDATORY)
Confirm the target IS a plugin per the cpv-plugin-validation-skill shape-detection reference (detection table, hard-refusal protocol). If .claude-plugin/plugin.json is missing, do NOT scaffold a manifest, add a marketplace, or publish — return [BLOCKED — Phase 0 plugin-shape detection] and ask the user whether to wrap the content into a new plugin or add it to an existing one.
Phase 1 — scan (read a COMPACT ledger, NEVER the full report)
Run the security scan via the LAUNCHER remote_validation.py security <plugin-root> --strict --json > <findings.json> — NEVER call validate_security.py directly (the isolation guard refuses with a "remote location" error); --json is a BOOLEAN flag that writes pure JSON to STDOUT (capture it to <findings.json>; do NOT use --report, which the --json branch ignores). Read a COMPACT finding surface, NEVER the full .md report — ingesting the whole report on every iteration is a top token sink (cost ≈ turns × per-turn-context: every raw report rides forward and is re-charged on each later turn).
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.

cpv-plugin-devitalizer-agent is an agent published in the GitHub repository Emasoft/claude-plugins-validation (4 stars, last pushed 3d ago), licensed MIT. It adds 236 tokens to every session and 3,399 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-08-31.
