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 | $0.07331 | $0.07331 |
| Opus 5.5 | $0.02932 | $0.02932 |
| Sonnet 5.5 | $0.01466 | $0.01466 |
| Haiku 4.5 | $0.00733 | $0.00733 |
Grade D, and why
workrail AGENTS.md scanned grade D 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 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Config note:** The project `.mcp.json` `workrail` entry should shadow the global `~/.claude/settings.json` entry when Claude Code is started from this repo. Verify via `/mcp` on first use -- if two `workrail` entries a Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

WorkRail -- Agent Instructions
CRITICAL: Three separate systems -- do not conflate them
WorkRail/WorkTrain is three distinct systems that share a common engine and session store. Understanding this separation is essential before working on any part of this codebase. Confusing them leads to wrong fixes, wrong architecture decisions, and real production problems.

WorkRail MCP Server (workrail start)
- A standalone stdio MCP server that Claude Code (and other MCP clients) connect to
- Provides
start_workflow,complete_step,continue_workflow,list_workflowsetc. as MCP tools - Must be bulletproof -- crashes here kill all in-flight Claude Code sessions that depend on it
- Has NOTHING to do with the daemon's internal machinery
- Source:
src/mcp/
WorkTrain Daemon (worktrain daemon)
- An autonomous agent runner that drives workflow sessions without human involvement
- Listens for triggers (webhooks, polling), spawns LLM agent loops, uses
complete_stepin-process - Completely separate process from the MCP server
- Does NOT depend on the MCP server being alive -- it calls the WorkRail engine directly in-process
- Source:
src/daemon/,src/trigger/
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.
- 2mo ago First seen · 498 lines · 7,331 tokens per session scan D 60d715891065
workrail AGENTS.md is an instructions file published in the GitHub repository EtienneBBeaulac/workrail (4 stars, last pushed yesterday), licensed MIT. It adds 7,331 tokens to every session, about $0.0293 per session on Opus 5.5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
