chronicle-mcp: Skill for Claude Code

.agents/skills/write-a-bug-report/SKILL.md

write-a-bug-report is a skill for Claude Code, Codex from loerei/chronicle-mcp. It costs 19 tokens per session (432 once invoked), scanned A, original, MIT.

A guide for documenting reproducible failures, tool errors, and bug reproductions in a structured Markdown report.

In plain words
What is it for?
Use it to write bug reports, capture failed file operations, preserve exact commands, and record minimal reproductions.
Why use it?
It keeps debugging records tied to observed inputs, outputs, logs, and exit codes instead of guesses about the cause.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is loerei/chronicle-mcp's own configuration. It tells Claude Code and Codex how to work on chronicle-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything chronicle-mcp configures →

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

write-a-bug-report 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.

What it actually says

Write a Bug Report

Document reproducible failures, tool errors, and bug reproductions in BUG_REPORT.md (or bug_<topic>.md).

Directives

  1. Zero Speculation: State ONLY observed inputs, stderr/stdout logs, exit codes, and measured timings; NEVER guess unverified root causes or fabricate durations.
  2. File Snapshot on Failure: When a file operation or patch fails, MUST copy target file(s) to scratch/replica_<filename> immediately before further modifications.
  3. Exact Payloads: MUST preserve complete raw command invocations, request payloads, and minimal repro scripts without truncation.

Template (BUG_REPORT.md)

# Bug Report: [Short Descriptive Summary]

**Target**: `<tool:method / command / package>`  
**Environment**: `<OS / Runtime / Versions>`  
**Severity**: `[Blocker / Major / Minor]`  
**Date**: YYYY-MM-DD  

---

## 1. Observed vs. Expected

### Observed Behavior (Actual)
- Exact error message, exit code, stack trace, or measured hang duration.
- Raw stderr/stdout log snippet.

### Expected Behavior
- Expected output, exit code, or clean error.

## 2. Reproduction (Repro)

* **Target Snapshot**: `[replica_filename](file:///absolute/path/to/replica)` (if applicable).
* **Trigger Payload / Command**:
```bash
<exact command, payload, or minimal reproduction script>

---

## Workflow

1. Snapshot affected target files to `scratch/replica_<filename>` if a write/patch failed.
2. Collect raw logs, error traces, and exact environment versions.
3. Write bug artifact to `BUG_REPORT.md` (or `<appDataDir>/brain/<convo-id>/bug_<topic>.md`).
4. Present file link and brief summary to user.
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.
