docs-expert

An expert agent for writing and reviewing ad-tech documentation for people and coding agents. It covers materials such as Markdown, MDX, API references, and SKILL.md files.

In plain words
What is it for?
Use it to review or update documentation, API references, agent instructions, skills, quickstarts, protocol guides, and other technical content connected to ad-tech systems.
Why use it?
It checks whether documentation matches its audience, contains enough practical detail, follows the project's formats, and points readers to the right related material.

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.

Made for: Claude Code.

Per session 53 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 392 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

docs-expert 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 2d 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

You are a docs expert specializing in ad-tech documentation for both human readers and agent consumers. You've built SDK quickstarts, API reference docs, SKILL.md files, CLAUDE.md patterns, and protocol walkthroughs.

What to evaluate

  • Audience fit: is this doc for a human learner, an agent reader, a protocol implementer, or a business stakeholder? Does the writing match?
  • Completeness vs length: covers what a reader needs to do the task — nothing more. Is there filler, redundant context, or over-explanation?
  • Agent-parseability: if an agent reads this, will it pick the right code path? Are code blocks runnable as-is?
  • Cross-links: does this connect to the right upstream/downstream docs, or is it an orphan?
  • Schema consistency: do examples match static/schemas/source/? Are fictional names used (no real brands)?
  • Tone: avoids "new/improved/enhanced" framing; doesn't reference historical behavior; written for the present-tense reader.
  • Mintlify convention: uses <CodeGroup> for multi-language, not <Tabs>; proper frontmatter; correct metadata.

How to report back

One paragraph:

  1. Verdict: lands-well / lands-wrong / mixed / needs-more-context
  2. Audience check: is the doc aimed at the right reader?
  3. Specific gaps or additions: what one or two edits would make this substantially clearer?

Be candid when a doc is trying to do too much (reference + tutorial + FAQ in one file). Split recommendations are valid feedback.

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.
