A contributor check that compares the plugin's structure and behavior with cached Claude Code documentation. It focuses on whether documented changes could cause compatibility problems.

Use it to check all plugin surfaces or focus on agents, skills, hooks, configuration, or the plugin manifest and marketplace files.

It separates genuine documentation or schema drift from outdated local assumptions before a release.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00045	$0.01653
Opus 5.5	$0.00018	$0.00661
Sonnet 5.5	$0.00009	$0.00331
Haiku 4.5	$0.00005	$0.00165

Security

Grade A, and why

docs-check 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 1mo 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.

Plugin Documentation Compatibility Check

Audience: Agents, Not Humans

Imperative-only. Validate plugins/ruby-grape-rails/ against current cached Claude Code docs. Contributor maintenance — NOT user-facing.

When to Use

Question	Answer this skill gives
Did Claude docs change in a way that breaks our plugin?	yes
Is this warning a real compatibility issue or stale local guidance?	yes
What new Claude feature is now documented and relevant?	yes
Is naming style / line count / repo preference unrelated to docs?	NO — out of scope

Usage

Command	Scope
`/docs-check`	all surfaces
`/docs-check --quick`	skip docs fetch, structural drift only
`/docs-check --focus=agents`	agents only
`/docs-check --focus=skills`	skills only
`/docs-check --focus=hooks`	hooks only
`/docs-check --focus=config`	plugin manifest + marketplace only

Execution Flow

1. Run Deterministic Baseline

Run all three, in order, to catch structural schema issues without docs interpretation:

Command	Covers
`claude plugin validate --strict plugins/ruby-grape-rails`	shipped plugin manifest + components
`claude plugin validate --strict .`	`.claude-plugin/marketplace.json`, which the plugin-directory run skips
`claude plugin validate --strict .claude`	contributor-only components under `.claude/`, validated as a bare component directory

--strict promotes unrecognized-field and missing-metadata warnings to errors. npm run validate runs the same three via scripts/validate-plugin.sh; CI runs them as separate lint-job steps.

2. Refresh Cached Docs (Unless `--quick`)

From repo root: bash ./scripts/fetch-claude-docs.sh.

--quick skips fetching; limits run to structural drift checks against existing cache.

3. Inventory Plugin Surfaces

Identify in-scope surfaces per --focus:

Surface	Paths
`agents`	`plugins/ruby-grape-rails/agents/*.md`
`skills`	`plugins/ruby-grape-rails/skills/*/SKILL.md`
`hooks`	`plugins/ruby-grape-rails/hooks/hooks.json`
`config`	`plugins/ruby-grape-rails/.claude-plugin/plugin.json`, `.claude-plugin/marketplace.json`

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
