A command that records a work session in a dated Markdown journal for the rem project. Each entry documents the goal, changes, technical lessons, and decisions.

Use it at the end of a work session to append to today's journal or create the next numbered journal file when none exists.

It removes the need to create or update the correctly numbered daily journal file by hand. It also preserves failed approaches and important implementation details for later sessions.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 387 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00387
Opus 5.5	$0.00000	$0.00155
Sonnet 5.5	$0.00000	$0.00077
Haiku 4.5	$0.00000	$0.00039

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 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.

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.

What it actually says

Write a journal entry for today's work session on the rem project.

Instructions

Determine today's date (YYYY-MM-DD format)
Check journals/ dir for an existing file matching today's date pattern *-<today's date>-journal.md
If a file for today exists: Append a new entry AFTER the --- separator at the bottom. Add a new --- at the end of your entry.
If no file for today exists: Create a new file with the next sequence number: <NNN>-<YYYY-MM-DD>-journal.md. Add --- at the end.

Entry Format

# Journal Entry <NNN> - <date> - <short title>

(or ## Session 2/3/etc if appending to existing file)

## Goal

<What was the objective this session?>

## What Changed

<Concrete list of what was built/fixed/refactored>

## Key Insights

<Technical learnings, gotchas discovered, things that failed and why, things that succeeded>

## Decisions Made

<Any architectural or design decisions and their rationale>

---

Rules

Be specific and technical - this is for future Claude sessions, not humans
Include code snippets for non-obvious patterns
Document what FAILED and why, not just successes
Keep it concise but complete - no fluff
Always end with --- separator for future appending

Post-Journal Housekeeping

After writing the journal entry, also update:

CLAUDE.md — Update implementation status, coverage numbers, integration test counts, and any new architecture/patterns added during the session.
Auto memory MEMORY.md — Update project status, coverage numbers, and add any new key patterns or architecture decisions discovered during the session.

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.

journal is a command published in the GitHub repository BRO3886/rem (157 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 387 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
