dx-docs

dx-docs is a skill for Claude Code, Codex from automagik-dev/genie. It costs 70 tokens per session (1,485 once invoked), scanned A, original, MIT.

A review guide for developer documentation, onboarding, error messages, and the overall contributor experience. It uses the Diátaxis model, which separates learning guides, task instructions, reference material, and explanations.

In plain words
What is it for?
It helps assess how quickly a new contributor can start, compare documentation with the actual code, improve onboarding, and report documentation gaps.
Why use it?
It reveals when documentation is missing, misleading, difficult to follow, or placed in the wrong form.

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

dx-docs 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 4d 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.

DX, Docs & Delivery Review

Runtime syntax: invoke the plugin copy through the active runtime's owner-qualified skill selector; use a bare selector only when intentionally selecting a user-tier copy (a separately installed personal copy; Genie no longer seeds this tier). Cross-skill prose below uses bare names as portable semantic routes; the orchestrator resolves the selector for the active runtime.

Lens

This lane treats documentation as four different things — tutorials (learning-oriented), how-to guides (task-oriented), reference (information-oriented), explanation (understanding-oriented) — and nearly every documentation failure is one quadrant's content misfiled in another, or a quadrant missing entirely. Documentation is judged by use, not by existence: a doc that cannot be followed is worse than no doc, because it costs trust. Developer experience is documentation's runtime — error messages, help text, and onboarding friction are docs delivered at the moment of need.

This lane's lens is inspired by the work of Daniele Procida, creator of the Diátaxis framework.

Mandate

Assess and report by default. Apply doc fixes only when the invocation explicitly asks — and only through the repo's documented docs workflow if it has one (submodules, docs repos, review gates). Findings outside this lane get a one-line handoff to the relevant lane skill under skills/. Judgments come from using the docs and the product, never from reading them approvingly.

Discover the Ground Truth First

Map the docs estate before judging it: where docs live (in-repo, submodule, separate site), which are public vs internal, what the contribution/onboarding path claims to be (README, CONTRIBUTING, CLAUDE.md/AGENTS.md), and what the product's real interface is — for a CLI, the live --help output of every command; for an API, the actual routes/signatures; for a library, the exported surface. The live interface is the truth; every doc, README table, and agent-context file is a claim to diff against it. Note the repo's stated DX bar (e.g. a 30-minute-contributor promise) — hold it to its own standard.

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.
