bug-from-user

bug-from-user is a skill for Claude Code, Codex from rockscy/solo-skills. It costs 60 tokens per session (1,164 once invoked), scanned A, original, MIT.

A guide for turning an unclear user complaint into a reproducible bug report. A reproducible bug report gives enough detail for a developer to trigger and investigate the problem.

In plain words
What is it for?
Use it to extract the trigger, expected result, actual result, and affected screen, URL, version, browser, or operating system from support messages. Missing information becomes a follow-up question.
Why use it?
It separates what the user expected from what actually happened and identifies missing details instead of guessing whether the issue is a bug.

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

bug-from-user 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 9d 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.

Bug from User / 用户反馈转 Bug

When to use

  • A user has reported a problem in prose (email, Discord, Twitter DM, support ticket).
  • The dev cannot tell from the message:
    • what was expected vs. what actually happened
    • the steps to reproduce
    • whether it's a real bug, user error, or a feature request in disguise
  • The dev wants a GitHub issue or internal note they can later sit down and fix.

When NOT to use

  • The user has already produced a clean, reproducible report. Don't re-process it.
  • The complaint is subjective ("it's slow", "it's ugly") with no measurable claim — that's a UX or perf investigation, not a bug.
  • The user is asking for a feature (e.g. "can you add X?") — file as feature request, not bug.

The four-question conversion

For any prose complaint, reduce it to:

  1. Trigger — what did the user do (action, click, command, input)?
  2. Expected — what did they expect to happen?
  3. Actual — what actually happened?
  4. Surface — where did it happen (URL, screen, version, browser, OS)?

If any of the four is missing, flag it as a follow-up question rather than guessing.

Output format

### Bug: <one-sentence headline, user-perspective>

**Trigger:**
1. <step>
2. <step>

**Expected:** <what they expected>

**Actual:** <what actually happened>

**Surface:** <version / browser / OS / URL>

**Confidence:** <high | medium | low>
- high: report is self-contained, can repro from this alone
- medium: 1–2 reasonable assumptions made
- low: significant guessing — ask user to confirm

**Follow-ups (if any):**
- <question to ask the user>

Worked example

Input (raw user email):

"hey i tried buying the pro plan tonight and the website just kept loading forever, i refreshed a few times then gave up. using safari on my macbook"

Output:

### Bug: Pro plan checkout hangs on Safari (macOS)

**Trigger:**
1. Visit pricing page on Safari (macOS).
2. Click "Pro plan" purchase button.
3. Observe checkout flow.

**Expected:** Stripe checkout opens within a few seconds.

**Actual:** Page stays in loading state indefinitely; refresh does not recover.

**Surface:** Safari on macOS. Version of Safari and macOS unknown. Pricing page URL unknown (likely /pricing).

**Confidence:** medium
- Assumed pricing page URL is /pricing.
- Assumed checkout uses Stripe.

**Follow-ups:**
- Which Safari version + macOS version?
- Does Chrome on the same machine reproduce it?
- Browser console errors (if comfortable opening DevTools)?

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.
