check-skill

check-skill is a command for coding agents from hmj1026/dhpk. It costs 13 tokens per session (435 once invoked), scanned A, original, MIT.

A command for checking whether skills meet defined quality rules, with an optional deeper manual review and JSON output.

In plain words
What is it for?
Use it to scan a skills directory, optionally inspect flagged skills in more depth, and produce a health report.
Why use it?
It helps find routing, scope, loading, and verification problems before a skill is used by agents.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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/hmj1026/dhpk/check-skill
Clone the repo
git clone --depth 1 https://github.com/hmj1026/dhpk

Or install dhpk, the plugin that ships this one along with the rest of its 19 commands, 36 agents.

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

check-skill 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 it actually says

Must read and follow the skill below before executing this command:

@skills/dhpk-skill-health-audit/SKILL.md

Context

  • Skills directory: !ls skills/ | wc -l skills
  • Commands directory: !ls commands/ | wc -l commands

Task

Run skill health check.

Arguments

$ARGUMENTS
Parameter Description
--deep Include manual review dimensions (Step 2)
--json Output JSON format

Workflow

Run skill-lint.js → [Optional: manual review] → Report + Gate
  1. Run automated lint: bash "${CLAUDE_PLUGIN_ROOT}/scripts/run-skill.sh" dhpk-skill-health-audit skill-lint.js --fix-hint (append --json if $ARGUMENTS contains --json)
  2. If --deep (from $ARGUMENTS): Read flagged skills and evaluate Why>What, scope, progressive loading, routing precision
  3. Output: Health report + Gate sentinel

Output

# Skill Health Check Report

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.
