atlas-session-lifecycle CLAUDE.md

atlas-session-lifecycle CLAUDE.md is an instructions file for coding agents from anombyte93/atlas-session-lifecycle. It costs 1,678 tokens per session, scanned C, original, MIT.

Repository instructions for Claude Code, an AI coding assistant, covering an Atlas Session Lifecycle project: an MCP server that manages AI-session context and checks work against contracts.

In plain words
What is it for?
It helps guide work on session management, contract checks, optional payment tools, file-based state, and registering tools in the server.
Why use it?
It gives the coding assistant the project’s purpose, structure, and rules so its changes fit the existing design.

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 C, and why

atlas-session-lifecycle CLAUDE.md scanned grade C with 2 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 6d 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.

Project Overview

Project: Atlas Session Lifecycle Goal: MCP server for AI session lifecycle management — persistent memory, soul purpose tracking, and contract verification for Claude Code Stack: Python 3.10+, FastMCP, FastAPI, HTMX, TailwindCSS, Playwright, pytest


Architecture

Modular Monolith Design

The MCP server (src/atlas_session/server.py) is a single FastMCP application with three tool domains:

  1. Session tools (session/): Session lifecycle management (init, validate, read_context, harvest, archive, check_clutter, cache/restore_governance)
  2. Contract tools (contract/): Bounty creation and verification with executable test criteria
  3. Stripe tools (stripe/): License and payment processing (optional)

Key pattern: Stateless tools with file-based state management. All state lives in session-context/ directories.

MCP Tool Registration

FastMCP tools are registered via decorator functions in each domain's tools.py. The server entry point aggregates all domains:

session_tools.register(mcp)
contract_tools.register(mcp)
stripe_tools.register(mcp)

Deterministic Operations

Session operations use JSON-outputting subcommands in session/operations.py. Each operation returns structured JSON that the skill layer (SKILL.md) interprets.

Contract/Bounty System

  • Contracts define executable test criteria at creation time
  • Verification just runs tests — no subjective judgment required
  • Criteria types: shell, context_check, file_exists, git_check
  • Local session-context/contract.json + optional AtlasCoin remote bounty

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.

atlas-session-lifecycle CLAUDE.md is an instructions file published in the GitHub repository anombyte93/atlas-session-lifecycle (88 stars, last pushed 1mo ago), licensed MIT. It adds 1,678 tokens to every session, about $0.0084 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
