In plain words
What is it for?
Use them when working on BLEnder to find files, understand its automation, and run the required linting, formatting, and pytest checks.
Why use it?
They explain the repository structure, important scripts, dependency context, and checks needed before pushing changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

blender CLAUDE.md 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.

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

BLEnder — Claude Instructions

What this repo is

GitHub Actions automation for Mozilla's Dependabot workflow. The actions run in this repo but target other repos. BLEnder sweeps for open Dependabot PRs, reviews major bumps, fixes CI failures, and auto-merges passing PRs.

Repo layout

  • .github/workflows/ — GitHub Actions workflow YAML files
  • scripts/ — Python and shell scripts that workflows call
  • config/ — default configuration (defaults.yml)
  • prompts/ — Claude prompt templates used by workflows
  • tests/ — pytest suite (mirrors scripts/ structure)
  • docs/ — dashboard web app (has its own CLAUDE.md)

Key files

  • scripts/automerge_dependabot.py — main orchestration script
  • scripts/sweep.py — finds open Dependabot PRs across repos
  • scripts/post_major_review.py — reviews major version bumps
  • scripts/github_utils.py — shared GitHub API helpers

Pre-push checks

Always run these before pushing to GitHub — they mirror the CI workflow in .github/workflows/ci.yml:

ruff check scripts/
ruff format --check scripts/
uv run --extra test pytest tests/

BLEnder

See .blender/agents.md for CI commands and dependency management context.

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.
