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 | $0.00101 | $0.02111 |
| Opus 5 | $0.00051 | $0.01056 |
| Sonnet 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 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 — 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 1mo ago), licensed MIT. It adds 101 tokens to every session and 2,111 once invoked, about $0.0005 per session on Opus 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.

context-vigilance
Lossless Group's framework for managing context-v/ directories in any project. Use whenever creating, updating, or organizing files in any context-v/ folder (specs, plans, prompts, blueprints, reminders, agent-skills, explorations, issues — plus the universal extra/ and sitemap/, and the experimental loops/…
surrealdb-canonical-layer
Verify a SurrealDB-backed canonical layer directly, over the surrealdb MCP server, instead of writing a disposable Node script per check. Use whenever the user asks to confirm a batch of writes landed correctly ("did the FreedomFest speakers get tagged right", "do these people have an org relationship", "check that…
search-lossless-corpus
Use whenever the user asks a question that prior work might already have answered — "what did we decide about X", "when did we ship X", "why did we choose X over Y", "has this failed before", "where did we put X" — and generally to ground answers in The Lossless Group's own corpus instead of training-data folklore.…
aictx
Use this skill when working in a repository that uses AICTX for repo-local operational continuity. Prefer AICTX MCP tools when available, fall back to CLI commands, resume before substantial work, and finalize factual continuity after work.
init
Initialize structured context for this project. Scaffolds .scs/ with all 11 concern bundles, scans the project, and recommends where to start.
context-mine
Extracts structured context from conversation exports (Slack, meeting transcripts, chat logs) into inbox for processing.
