lint

lint is a command for Claude Code from sk-lim19f/Hypomnema. It costs 35 tokens per session (690 once invoked), scanned A, original, MIT.

A command that checks wiki Markdown pages for required frontmatter and broken wikilinks. Frontmatter is metadata at the top of a Markdown file, while wikilinks are links written like [[page name]].

In plain words
What is it for?
Use it to check wiki health before a commit and after bulk edits, page renames, or other documentation changes.
Why use it?
It finds missing metadata and links to pages that no longer exist before they cause navigation or publishing problems.

Command for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 3d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are running /hypo:lint. Validate all wiki pages for frontmatter correctness and broken [[wikilink]] references.

What this checks

  • Every .md file under pages/ and projects/ should have frontmatter (missing frontmatter is a warning)
  • Required fields: title, type
  • type must be one of the recognised values (concept, source-summary, learning, adr, …)
  • updated field should be present
  • All [[wikilinks]] must resolve to an existing page slug

Step 1 — Run script

Bundled scripts here run via ${CLAUDE_PLUGIN_ROOT}/scripts/. To resolve that package root: if ${CLAUDE_PLUGIN_ROOT} is already an absolute path, use it; otherwise read pkgRoot from ~/.claude/hypo-pkg.json (only when non-empty and the target script exists under it); otherwise use the hypo@hypomnema (or legacy hypomnema@hypomnema) installPath in ~/.claude/plugins/installed_plugins.json; if none resolve, stop and tell the user to run hypomnema upgrade --apply (or /hypo:upgrade on a plugin install) or reinstall instead of guessing the cache layout.

If the user specified a Hypomnema directory, pass it as --hypo-dir="<path>". Otherwise omit the flag and the script resolves the Hypomnema root automatically via HYPO_DIR → hypo-config.md scan → ~/hypomnema.

Step 2 — Run lint

node ${CLAUDE_PLUGIN_ROOT}/scripts/lint.mjs [--hypo-dir="<path>"] [--json] [--fix]

Options:

  • --json — output results as JSON (useful for tooling)
  • --fix — auto-add missing updated field (safe repairs only; no other fields are modified)

Show the output verbatim.

Step 3 — Interpret results

  • ✓ No lint issues found — Hypomnema is clean
  • ✗ <file>: <message> — error (missing required field or malformed frontmatter); must be fixed
  • ⚠ <file>: <message> — warning (unknown type, missing updated, broken link); worth fixing

A non-zero exit code means at least one error was found (warnings alone do not produce a non-zero exit code).

Step 4 — Offer to fix

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.
