lint-constitution

lint-constitution is a command for coding agents from joeyycli/constitution-lint-action. It costs 18 tokens per session (198 once invoked), scanned A, original, MIT.

A linter for an agent constitution file, such as CLAUDE.md, that checks for missing operational safety rules. It reports heuristic pass or fail results.

In plain words
What is it for?
Use it to check a constitution file and explain each failed guardrail check; it does not edit the file.
Why use it?
It can reveal missing guardrails such as spending limits, escalation rules, or instructions to treat outside content as data.

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.

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/joeyycli/constitution-lint-action/lint-constitution
Clone the repo
git clone --depth 1 https://github.com/joeyycli/constitution-lint-action

Or install constitution-lint, the plugin that ships this one along with the rest of its 1 command, 1 MCP server.

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

lint-constitution 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 5d 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

Linter output for the requested file:

!f="$ARGUMENTS"; python3 "${CLAUDE_PLUGIN_ROOT}/constitution_lint.py" "${f:-CLAUDE.md}"

Summarize the result for the user. For each FAIL, explain in one line what guardrail is missing and what a satisfying rule would look like (the check names describe the missing guardrail — e.g. a concrete spend limit, an explicit escalation path, a rule treating web/email/API content as data rather than instructions). If every check passes, say so briefly. These are heuristic pattern checks on the document text, not a guarantee the rules are sound — say that too. Do not edit any file unless the user explicitly asks.

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.
