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.

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 | $0.00070 | $0.00981 |
| Opus 5 | $0.00035 | $0.00491 |
| Sonnet 5 | $0.00014 | $0.00196 |
| Haiku 4.5 | $0.00007 | $0.00098 |
Grade A, and why
validate-all 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 8d 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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Validate Claude Code Project
Runs claudelint check-all to validate all Claude Code project files including CLAUDE.md, skills, settings, hooks, MCP servers, and plugin manifests.
Usage
claudelint check-all $ARGUMENTS
Options
Available flags:
--verbose- Show detailed validation output--warnings-as-errors- Treat warnings as errors--explain- Show detailed explanations and fix suggestions--format <format>- Output format: stylish, json, compact (default: stylish)--config <path>- Path to custom config file--fast- Fast mode: skip expensive checks--color/--no-color- Control color output
Examples
Example 1: Plugin won't load after changes
User says: "I just updated my CLAUDE.md and added a new skill, but now my plugin isn't loading" What happens:
- Skill runs
claudelint check-all - Finds CLAUDE.md exceeds 50KB (blocking issue)
- Finds new skill has wrong capitalization in allowed-tools
- Shows both issues need fixing before plugin will load
Result: User identifies why plugin broke and fixes both issues
Example 2: Pre-commit validation failed
User says: "My git pre-commit hook is failing but I don't know which validator is the problem" What happens:
- Skill runs
claudelint check-all --verbose - Shows validate-mcp failed: invalid transport type "sse" (deprecated)
- Shows validate-hooks passed, validate-skills passed, etc.
- Points to specific .mcp.json file and line number
Result: User fixes the one failing validator (MCP config) and commit succeeds
Example 3: After npm install, verify everything still works
User says: "I just upgraded claude-code-lint, make sure I didn't break anything" What happens:
- Skill runs
claudelint check-all - Detects new rules flagging previously-allowed patterns
- Shows deprecation warnings for old syntax
- Suggests migration path for deprecated features
Result: User knows what needs updating after version upgrade
What ships with it
4 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.
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.
