genblaze: Skill for Claude Code

.claude/skills/verify-docs/SKILL.md

verify-docs is a skill for Claude Code from backblaze-labs/genblaze. It costs 51 tokens per session (894 once invoked), scanned A, original, MIT.

A documentation freshness checker for a code repository. It checks whether documentation dates are current, whether Python examples can be parsed, and whether links between documents work.

In plain words
What is it for?
Use it to audit the repository’s main Markdown files and docs folder monthly, before a release, or after a major refactor.
Why use it?
It finds stale or incomplete documentation before releases or after large code changes. It reports problems for human review instead of changing the documents automatically.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is backblaze-labs/genblaze's own configuration. It tells Claude Code how to work on genblaze 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 genblaze 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

verify-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 2mo 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.

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verify docs freshness

Run the four checks below and produce a single report. Do NOT auto-fix — surface findings for human review (stale docs usually need a human to decide whether behavior is still accurate).

1. Stale last_verified stamps

Every canonical doc in this repo carries <!-- last_verified: YYYY-MM-DD --> near the top.

  • Glob: README.md, ARCHITECTURE.md, AGENTS.md, CLAUDE.md, CONTRIBUTING.md, docs/**/*.md.
  • For each file, extract the stamp. Flag as P1 stale when:
    • Stamp is absent (canonical docs must have one), OR
    • Stamp is >60 days old, OR
    • Stamp date is earlier than the most recent commit touching the file's owning module per the Doc Update Mapping in docs/dev-workflows.md.

Owning-module lookup (from docs/dev-workflows.md):

Doc Owning module
docs/features/pipeline.md libs/core/genblaze_core/pipeline/
docs/features/provider-system.md libs/core/genblaze_core/providers/
docs/features/media-embedding.md libs/core/genblaze_core/media/
docs/features/object-storage.md libs/core/genblaze_core/storage/ + libs/connectors/s3/
docs/features/parquet-sink.md libs/core/genblaze_core/sinks/
docs/features/manifest-provenance.md libs/core/genblaze_core/canonical/ + libs/core/genblaze_core/models/manifest.py
docs/features/cli.md cli/
ARCHITECTURE.md whole repo — use root mtime
docs/app-workflows.md libs/core/
docs/dev-workflows.md Makefile + .github/workflows/

Use git log -1 --format=%cs -- <path> to get last-touched date for a module.

2. Python example syntax

Every Python fenced block in docs/features/*.md should at minimum be parseable.

  • For each code block ( python ... ), write to a temp file and run python3 -c "import ast; ast.parse(open(p).read())".
  • Report parse errors only. Ignore import-resolution failures (examples use real API keys that aren't available in the audit env).

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.

Use this Skill when a game plan needs a single-subject concept image, a character reference cleaned for image-to-3D, or a front-facing transparent T-pose image for downstream character reconstruction. T-pose generation is an image-generation and image-editing task; it is not a separate asset category.
