validate

validate is a command for coding agents from C0ntr0lledCha0s/claude-code-plugin-automations. It costs 10 tokens per session (784 once invoked), scanned A, original, MIT.

A command for checking a Claude Code component or plugin against its required structure and settings.

In plain words
What is it for?
Use it to validate agents, skills, commands, hooks, or complete plugins for schema compliance and documented best practices.
Why use it?
It finds the component type, runs the matching validator, and reports failures, issues, and recommendations before the component is used.

Install

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.

agentmods
npx agentmods add commands/c0ntr0lledcha0s/claude-code-plugin-automations/validate
Clone the repo
git clone --depth 1 https://github.com/C0ntr0lledCha0s/claude-code-plugin-automations

Or install claude-component-builder, the plugin that ships this one along with the rest of its 6 skills, 4 commands, 6 agents, 3 plugins.

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

validate 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 4d 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.

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.
