Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00101 | $0.02111 |
| Opus 5.5 | $0.00040 | $0.00844 |
| Sonnet 5.5 | $0.00020 | $0.00422 |
| Haiku 4.5 | $0.00010 | $0.00211 |
Grade A, and why
journal-optimizer 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 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.
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 — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Journal Optimizer
Guided workflows for intelligently pruning, cleaning, and optimizing a
memory-journal-mcp database. Every operation uses the soft-delete system
as a safe first pass — entries remain recoverable via restore_backup
until explicitly purged.
Prerequisites
The following tool groups must be enabled:
| Group | Required Tools | Purpose |
|---|---|---|
admin |
delete_entry, update_entry |
Soft-delete entries |
analytics |
get_statistics |
Importance scores, graph stats |
search |
search_entries, search_by_date_range, semantic_search |
Find candidates |
backup |
backup_journal, list_backups, restore_backup |
Safety net |
codemode |
mj_execute_code |
Batch operations |
relationships |
visualize_relationships |
Orphan detection |
If any required group is missing, inform the user and suggest adding it
via --tool-filter or MEMORY_JOURNAL_MCP_TOOL_FILTER.
Importance Score Reference
The server computes importance scores (0.0–1.0) for every entry using a weighted formula. Understanding this formula is essential for making intelligent pruning decisions.
Formula
| Component | Weight | Max Score | How It's Earned |
|---|---|---|---|
| Significance | 0.30 | 0.30 | Entry has a significance_type (milestone, decision, release, etc.) |
| Relationships | 0.35 | 0.35 | Entry has ≥5 relationships (linear scale: 1 rel = 0.07) |
| Causal | 0.20 | 0.20 | Entry has ≥3 causal relationships (blocked_by, resolved, caused) |
| Recency | 0.15 | 0.15 | Created within the last 90 days (linear decay to 0 at day 90) |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-optimizer is a skill published in the GitHub repository neverinfamous/memory-journal-mcp (20 stars, last pushed 3mo ago), licensed MIT. It adds 101 tokens to every session and 2,111 once invoked, about $0.0004 per session on Opus 5.5. 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.
Other skills, from other repositories
context-end
Close a workspace session by reviewing a proposed summary, recording approved outcomes, updating state and decisions, and checking repository safety. Use only when the user explicitly asks to end, close, or hand off the current session.
context-update
Save a brief mid-session checkpoint to this workspace and update current state only when a priority or open thread changed. Use only when the user explicitly asks to checkpoint or save current progress.
init
Initialize structured context for this project. Scaffolds .scs/ with all 11 concept bundles, scans the project, and recommends where to start.
permanent-memory-loader
Loads permanentmemory.md summary lines (≤120 always-loaded tokens, hard cap 200). Surfaces durable wisdom from past Epics into the current session. Silent if .claude/memory/ does not exist.
memory-audit
Audit MEMORY.md against the memory discipline — oversized sections, settled multi-session patterns that belong in knowledge/concepts/, session-headed chronicle blocks, restated rules, copied numbers, stale entries. Produces a move plan as a table for approval, then executes the approved moves atomically. Use when the…
close-session
An end-of-session workflow that reviews new lessons, asks before promoting repeated patterns, refreshes memory files, and writes a handoff.
