journal-optimizer — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited journal-optimizer (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The primary manifest — the file an agent reads to learn what this artifact does.
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.
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.
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.
| 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) |
| Score | Label | Meaning |
|---|---|---|
0.00 | Expendable | No significance, no relationships, older than 90 days |
0.01–0.14 | Low | Minimal context — weak tags or a single old relationship |
0.15–0.29 | Moderate | Has some context but not structurally important |
0.30–0.49 | High | Well-connected or has significance markers |
0.50+ | Critical | Major decisions, densely linked entries, milestones |
Key insight: Entries scoring0.00have zero structural value to the knowledge graph. They are safe to soft-delete in virtually all cases. Entries scoring0.01–0.14should be reviewed individually.
These rules are mandatory for all workflows:
permanent: true unless the user explicitly says"permanent delete" or "hard delete"
backup_journal before any batch delete — abort ifthe backup fails
significance_type set without explicituser approval, regardless of other scores
mass deletion
entry_type: 'maintenance' and tag database-optimizer
For all destructive workflows (2–5), execute this exact sequence once the candidate list is prepared:
backup_journal. ABORT immediately if the backup fails.Analyze the database to surface low-importance entries without modifying anything. This is the recommended starting point for all optimization work.
Step 1 & 2 — Gather stats and score entries: _Read and execute the Workflow 1 code block in references/optimizer-scripts.md._
Step 3 — Present results:
Render the distribution as a table:
| Tier | Count | Action |
|---|---|---|
| Critical (≥0.50) | N | Keep — these are structural anchors |
| High (0.30–0.49) | N | Keep — well-connected entries |
| Moderate (0.15–0.29) | N | Review individually if space is needed |
| Low (0.01–0.14) | N | Candidates for cleanup with user review |
| Expendable (0.00) | N | Safe to soft-delete |
Show the expendable sample with IDs, types, ages, and snippets. Ask the user which tier(s) they want to target for cleanup.
Soft-delete entries matching user-selected criteria from the audit.
Find and soft-delete entries with zero relationships.

significance_type set — these should NOT be deleted without explicit approval.Alternative to deletion: For orphans that have value but lack connections, suggest using link_entries to connect them to related entries instead of deleting them.WARN: High tool-call budget — This workflow executes an N×N semantic search loop. Limit the search set to 50 entries to avoid exhausting rate limits.
Find entries with semantically similar content that may be redundant.
_Read and execute the Workflow 4 code block in references/optimizer-scripts.md._
Note: Semantic search requires the vector index. Ifget_vector_index_statsshows zero indexed entries, suggest runningrebuild_vector_indexfirst.
Clean up entries by entry_type — useful for removing bulk categories that were misclassified or have outlived their usefulness.

Every workflow creates a backup before mutations. To revert: _Follow the restoration commands in references/optimizer-scripts.md._
Important: Soft-deleted entries are physically present but excluded from queries. They are only permanently removed via permanent: true, restoring an old backup, or rebuilding from an export.After completing any workflow, recommend these follow-up actions:
rebuild_vector_index
get_statistics
consider linking remaining orphans to related entries
| Tool/Workflow | Relationship |
|---|---|
| Auto-Prune (startup) | Automated version of Workflow 2 with fixed thresholds |
get_statistics | Primary data source for importance scores and graph metrics |
backup_journal | Safety gate for all destructive operations |
restore_backup | Revert mechanism for soft-deleted entries |
rebuild_vector_index | Post-cleanup maintenance to clean stale embeddings |
link_entries | Alternative to deletion — connect orphans instead of removing them |
