journal

journal is a command for Claude Code from terrene-foundation/metis. It costs 15 tokens per session (741 once invoked), scanned A, original, Apache-2.0.

A project journal manager for recording and finding decisions, discoveries, risks, trade-offs, connections, and gaps across coding sessions. It also shows the journal's current status and recent entries.

In plain words
What is it for?
Use it to check journal activity, create a typed entry, or search past project notes.
Why use it?
It keeps important project knowledge from being lost between sessions or scattered across conversations.

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

journal 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 4d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Manage the project journal. The journal is the primary knowledge trail — it captures decisions, discoveries, trade-offs, risks, connections, and gaps across sessions.

Parse $ARGUMENTS:

  • Empty or "status": Show journal status
  • "new TYPE topic": Create a new journal entry (e.g., new DECISION chose-event-driven)
  • "search QUERY": Search existing entries by topic or tag

Action: Status (default)

  1. Determine the active workspace:

    • If working in a workspace, use it
    • Otherwise, use the most recently modified directory under workspaces/ (excluding instructions/)
  2. In the workspace's journal/ directory:

    • Count total entries
    • Count entries by type (DECISION, DISCOVERY, TRADE-OFF, RISK, CONNECTION, GAP)
    • List the 5 most recent entries with their date, type, and topic (from frontmatter)
    • Show the highest entry number (for next entry reference)
  3. Present as a compact summary.


Action: New Entry

  1. Parse the TYPE and topic from arguments. Valid types: DECISION, DISCOVERY, TRADE-OFF, RISK, CONNECTION, GAP.

  2. Determine the next sequential number by checking the highest existing NNNN- prefix in the journal directory. If no entries exist, start at 0001.

  3. Create the file at journal/NNNN-TYPE-topic.md with this structure:

---
type: [TYPE]
date: [today's date, YYYY-MM-DD]
project: [workspace name]
topic: [topic description]
phase: [current COC phase: analyze | todos | implement | redteam | codify | deploy]
tags: []
---

## [Section heading appropriate to type]

[Content — prompt the user for details if not provided]
  1. Type-specific structure:

    • DECISION: Sections for Decision, Alternatives Considered, Rationale, Consequences
    • DISCOVERY: Sections for What Was Discovered, Why It Matters, Follow-Up
    • TRADE-OFF: Sections for Trade-Off, What Was Gained, What Was Sacrificed, Acceptable Because
    • RISK: Sections for Risk Identified, Likelihood and Impact, Mitigation, Follow-Up
    • CONNECTION: Sections for Connection, Components Linked, Why This Matters
    • GAP: Sections for What Is Missing, Why It Matters, How to Resolve

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.
