hippocampus: Skill for Claude Code

.agents/skills/lint/SKILL.md

lint is a skill for Claude Code, Codex from sturlese/hippocampus. It costs 84 tokens per session (133 once invoked), scanned A, original, MIT.

A health-check workflow for a vault, meaning a collection of linked notes or wiki pages. It checks formatting, links, duplicates, orphan pages, indexes, and editorial issues, then offers fixes for approval.

In plain words
What is it for?
Use it to inspect or clean a vault, review its structure, or run a requested lint or health check.
Why use it?
It helps find broken links, stale claims, missing pages, and other problems that make a note collection unreliable.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths; installed under .agents/ (shared by several agents); mentions Codex.

This is sturlese/hippocampus's own configuration. It tells Claude Code and Codex how to work on hippocampus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything hippocampus configures →

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 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 7d 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

Codex adapter

Read .claude/skills/lint/SKILL.md completely and follow it as the canonical lint workflow. Its contract applies unchanged to Codex.

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.
