Why use it?
It catches configuration and metadata problems before generated add-ons are used or distributed.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is shyamsridhar123/agentsmith-cli's own configuration. It tells Claude Code and Codex how to work on agentsmith-cli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agentsmith-cli configures →

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

asset-validation-rules 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 6d 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 it actually says

Asset Validation Rules

Validate generated skills, agents, hooks, and registry entries with actionable errors/warnings.

When to Use

Use this skill when:

  • Working with code in src/commands/validate.ts/

  • User mentions "frontmatter"
  • User mentions "yaml"
  • User mentions "hooks"
  • User mentions "registry"

Patterns

  • SKILL.md frontmatter checks for name/description
  • agent.yaml required fields and skill existence
  • hook event validation against whitelist
  • registry JSON line parsing with required fields
  • summary with errors/warnings and exit code

Examples

await validateCommand('.', { verbose: true });

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.
