config

A command for showing how the dev-workflow add-on is configured for a project. It reports each setting, where it came from, and configuration entries that are being ignored.

In plain words
What is it for?
Use it to inspect guard settings, identify configuration problems, see whether values come from defaults, files, or environment variables, and optionally change a value.
Why use it?
It exposes cases where a configuration file says one thing but the running checks use another value, including fallback behavior after a parsing error. This prevents debugging the wrong settings.

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.

Or install dev-workflow, the plugin that ships this one along with the rest of its 5 skills, 1 command, 7 agents, 3 hooks.

Per session 47 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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

config 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.

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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Report — and optionally change — how this project has configured the plugin.

The CLI is python3 "${CLAUDE_SKILL_DIR}/../../hooks/config.py" <cmd> (this resolves to the plugin's hooks/config.py). It imports the guards themselves rather than restating their defaults, so its report cannot drift from the hooks that are actually running. Never answer this from memory or by reading the JSON files yourself: the whole point is the gap between what a file SAYS and what the guards DO, and only the CLI computes that.

Showing

Run exactly:

python3 "${CLAUDE_SKILL_DIR}/../../hooks/config.py" show

Present the output as a short table per section. Two things carry the value here, so do not flatten them away:

  • The PROBLEMS block, if there is one — lead with it. Every guard falls back to its defaults when a config file will not parse, and says nothing; a ! line means the project believes it configured something that is not happening. Quote the line and say plainly what is running instead.
  • The source column. default / file / env <VAR> / file, IGNORED. That last one is the interesting case: the key was written, the guard read it, and the value is the default anyway — a wrong type, or a regex that will not compile.

If nothing is overridden and there are no problems, say so in one line rather than reprinting a wall of defaults: the project is on stock settings.

Setting

Only when the user asks for a change. Run:

python3 "${CLAUDE_SKILL_DIR}/../../hooks/config.py" set <key> <value>

Keys: comment-guard.enabled, comment-guard.density.floor, comment-guard.density.min_ratio, test-guard.enabled, test-guard.checks.fakes, test-guard.checks.assertions, test-guard.max_empty_args, models.<agent>. Values: on / off, a number, a model alias (opus, sonnet, haiku, fable, inherit) or a claude-* id, or default to drop the key.

The file is a diff against the defaults, so a value equal to its default is removed rather than written — that is intended, not a failure. The command refuses to write over a file it cannot parse; when it does, tell the user to fix or delete that file rather than trying to repair it yourself.

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.

config is a skill published in the GitHub repository tandnguyendev/dev-workflow (2 stars, last pushed 8d ago), licensed MIT. It adds 47 tokens to every session and 816 once invoked, about $0.0002 per session on Opus 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.
