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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01678 | $0.01678 |
| Opus 5.5 | $0.00671 | $0.00671 |
| Sonnet 5.5 | $0.00336 | $0.00336 |
| Haiku 4.5 | $0.00168 | $0.00168 |
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 1mo 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:
- Session tools (
session/): Session lifecycle management (init, validate, read_context, harvest, archive, check_clutter, cache/restore_governance) - Contract tools (
contract/): Bounty creation and verification with executable test criteria - 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

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 (85 stars, last pushed 2mo ago), licensed MIT. It adds 1,678 tokens to every session, about $0.0067 per session on Opus 5.5. 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.
