dx-roaster

dx-roaster is a skill for Claude Code from Varnan-Tech/opendirectory. It costs 130 tokens per session (2,730 once invoked), scanned A, original, MIT.

A developer-experience audit for a GitHub repository. It scores ten parts of the experience, including setup, documentation, examples, trust, and the time needed to reach a first success, then writes a roast and improvement plan.

In plain words
What is it for?
Use it to evaluate an open-source project before a launch or public release. It produces a roast, an action plan, an ideal README, and a JSON score report based on the repository's evidence.
Why use it?
A repository may work well but still be difficult for new developers to understand or install. The audit turns those obstacles into specific, ranked changes.

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-roaster 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.

How it starts

The opening of the file, as written. The whole thing — 272 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dx-roaster

Roasts a GitHub repo's developer experience. Produces four files: roast.md, action-plan.md, ideal-readme.md, score.json. Built for OSS maintainers and dev-tool founders preparing for Show HN, Product Hunt, or any launch where the first five minutes matter.


Critical rules (read before every run)

  1. Read all three reference files BEFORE scoring. references/scoring-rubric.md, references/roast-voice-guide.md, references/readme-template.md. The rubric is non-negotiable — use the exact 10 dimensions.

  2. Score every dimension on the 0–10 scale. Never skip. Missing data = score 0, not "N/A".

  3. Roast must cite specific findings. Quote bad lines verbatim. Reference file paths. Cite line numbers when possible. Never write generic platitudes like "documentation could be better".

  4. Tone matters. Default honest. Switch voice per references/roast-voice-guide.md. Brutal is funny but never personal. Kind is encouraging but still specific.

  5. Action plan is impact-ranked, not severity-ranked. Use impact × (1 / effort). A 5-minute fix that adds 10 points ranks above a 2-hour fix that adds 12 points.

  6. Never invent URLs. When writing ideal-readme.md, use <placeholder> syntax for missing links. Roast will tell maintainer to fill in.

  7. Never name maintainers or contributors. Roast the work, not the people.

  8. Output exactly four files in dx-roast/. Do not write to other locations. Do not skip files.


Step 1: Intake

Required:

  • repo — local path (default .) OR https://github.com/owner/repo URL

Optional:

Parameter Default Description
tone honest brutal / honest / kind
output_dir dx-roast/ Where to write the 4 output files
compare_to none Optional second repo URL for benchmark comparison

If repo is a URL: clone to a temp dir using git clone <url> /tmp/dx-roast-<short-hash>. Scan from there. Delete temp dir after run.

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.

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.
