atlas-bootstrap

atlas-bootstrap is a skill for Claude Code, Codex from madaeroblade/atlas. It costs 37 tokens per session (654 once invoked), scanned A, original, MIT.

A repository setup tool that builds or refreshes Atlas, a project knowledge system for helping coding agents find reliable information about a codebase.

In plain words
What is it for?
It discovers project details, creates Atlas files, retrieval data, test fixtures, maintenance rules, and Claude instructions tailored to the repository.
Why use it?
It replaces scattered project knowledge with a compact, searchable structure based on the repository’s actual technologies and files.

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

atlas-bootstrap 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.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Atlas Bootstrap

Resolve Atlas

Use the Atlas root defined by the user's global Claude instructions.

Expected engine:

$ATLAS_ROOT/engine/bootstrap/

Expected profiles:

$ATLAS_ROOT/profiles/

Expected templates:

$ATLAS_ROOT/templates/

If Atlas root cannot be resolved or required files are missing, stop and report the missing path.

Execute

Read and follow, in order:

  1. $ATLAS_ROOT/engine/bootstrap/ENGINE.md
  2. $ATLAS_ROOT/engine/bootstrap/RECONNAISSANCE.md
  3. $ATLAS_ROOT/profiles/generic/PROFILE.md

Then detect repository technologies.

Load only matching profile PROFILE.md files and their VALIDATION.md files when present.

Examples:

  • Laravel → profiles/laravel/
  • Vue → profiles/vue/
  • Zend Framework 1 → profiles/zend-framework-1/
  • Swift → profiles/swift/
  • React → profiles/react/
  • React Native → profiles/react-native/
  • React Native Windows → profiles/react-windows/

Multiple profiles may apply.

Templates

Use Atlas templates as structural guidance.

Do not blindly copy placeholders.

Generate project-specific .atlas/ artifacts from repository evidence.

Existing Atlas

If .atlas/ already exists:

  • treat this as rebuild/reconciliation;
  • preserve trustworthy project knowledge;
  • revalidate against source;
  • remove obsolete knowledge;
  • do not accumulate duplicate files.

Claude project instructions

If the repository has CLAUDE.md, integrate Atlas as the project knowledge layer.

Measure CLAUDE.md in bytes before and after. It must end up smaller.

CLAUDE.md is loaded on every task in the repository, forever. It is the most expensive place a fact can live, which is the whole reason Atlas exists.

  • Move durable subsystem/project knowledge into .atlas/, leaving a pointer, not a summary.
  • Do not add a "where to look" table. GRAPH.yaml is that table, and it is loaded on demand instead of always.
  • Preserve project-wide operating rules — how to work here is not Atlas knowledge.
  • Do not remove externally managed or generated instruction blocks.

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.
