atmos: Skill for Claude Code

.claude/skills/fix-log/SKILL.md

fix-log is a skill for Claude Code from cloudposse/atmos. It costs 50 tokens per session (700 once invoked), scanned A, original, Apache-2.0.

A documentation rule for recording every completed fix in a dated Markdown file under docs/fixes/.

In plain words
What is it for?
Use it when implementing, reviewing, or documenting bug fixes, repairs, debugging work, infrastructure changes, or workflow fixes.
Why use it?
It keeps a durable record of what changed, why it changed, what checks actually ran, and any remaining work, without rewriting older records.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md.

This is cloudposse/atmos's own configuration. It tells Claude Code how to work on atmos 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 atmos configures →

About the project

Atmos is an infrastructure runtime that coordinates tools such as Terraform, OpenTofu, Kubernetes, Helm, Packer, Ansible, and containers through consistent commands and configuration. It is for teams running cloud infrastructure on laptops, in CI, or through AI agents across environments and regions. Its catalogue entries provide skills, agents, commands, and other add-ons for Atmos workflows.

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

fix-log 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-fix-doc.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fix Documentation

Every implemented fix must leave a short Markdown record in docs/fixes/.

docs/fixes/ already contains 90+ pre-existing records in an older, inconsistent format (some with a # Fix: <title> heading, some without; some with a **Date:** line, some without; and 25+ different ad hoc ## section names across the set — ## Problem, ## Root Cause, ## Tests, ## Related, etc.). Do not migrate those — they stay as-is. All new records use the merged format below, which keeps the old convention's most useful, scannable elements (the # Fix: heading, the explicit **Date:** line) and adopts a single, consistent five-section structure instead of ad hoc headers.

Workflow

  1. Before final ready status, create or update docs/fixes/YYYY-MM-DD-<slug>.md.
  2. Use the current local date for YYYY-MM-DD.
  3. Use a lowercase slug with letters, numbers, and hyphens.
  4. Record what changed, why it changed, validation that actually ran, and follow-ups.
  5. Do not invent validation. If a check was skipped or blocked, say why.
  6. Follow CLAUDE.md's Follow-up Tracking (MANDATORY) rule: never create GitHub issues for an implementation that has not merged into main. Fix required work in the active PR or stack and keep remaining tasks in its PRD or task list. The Follow-ups section may link to that document; an issue number is not required. Only for already-merged features, track genuinely deferred work in a GitHub issue and link it by number.

Required Document Shape

# Fix: <Title>

**Date:** YYYY-MM-DD

## Summary

## Context

## Changes

## Validation

## Follow-ups
  • <Title> is a short human-readable description of the fix (inline code spans are fine, e.g. # Fix: `describe affected` now checks `source` and `provision` sections).
  • **Date:** restates the filename's date for at-a-glance scanning; keep it in sync with the filename.
  • Use None. in Follow-ups only when no follow-up is known.

What ships with it

1 file 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.
