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 | $0.01546 | $0.01546 |
| Opus 5 | $0.00773 | $0.00773 |
| Sonnet 5 | $0.00309 | $0.00309 |
| Haiku 4.5 | $0.00155 | $0.00155 |
Grade A, and why
jrnl-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories โ prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency โ measured 8d 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

Git Workflow - MUST READ
CRITICAL: The main branch is protected. Direct pushes are blocked.
Before ANY Git Operation
git branch # Always check current branch first
Required Workflow
develop (work here) โ PR โ main (protected)
-
Always work on
developbranchgit checkout develop -
Commit and push to develop
git add <files> git commit -m "message" git push origin develop -
Create PR to merge into main
gh pr create --base main --head develop -
Never commit directly to main - It will be rejected by branch protection rules.
If You Accidentally Commit to Main
# Cherry-pick to develop
git checkout develop
git cherry-pick <commit-hash>
git push origin develop
# Reset main to remote
git checkout main
git reset --hard origin/main
Project Overview
This is a jrnl MCP (Model Context Protocol) server that provides a read-only API for AI assistants to access and analyze journal entries from the jrnl command-line tool.
Current State: Phase 1 improvements in progress (see docs/todo.md for details).
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.
