Run /mnemonic:list --namespaces to see available namespaces from loaded ontologies.

/mnemonic:custodian

Comprehensive memory system custodian for health checks, validation, and maintenance.

Usage

/mnemonic:custodian [operation] [options]

Operations

audit (default)

Full health check: links, decay, relationships, orphans, frontmatter completeness.

/mnemonic:custodian audit [--fix] [--dry-run] [--json]

Runs all checks in a single pass:

1. Validate memory frontmatter (required fields, types, formats)
2. Validate wiki-links and frontmatter relationship targets
3. Validate ontological relationship types
4. Recalculate decay strength values
5. Detect orphaned memories (no incoming references)

relocate

Move memories when project or org names change. Auto-updates all cross-references.

/mnemonic:custodian relocate <old-path> <new-path> [--dry-run] [--commit]

Example:

# Project renamed from old-api to new-api
/mnemonic:custodian relocate ${MNEMONIC_ROOT}/zircote/old-api ${MNEMONIC_ROOT}/zircote/new-api

Steps:

1. Build link index across all memory roots
2. Update path references in all memories
3. Move files (using git mv when available)
4. Clean up empty directories

validate-links

Check and optionally repair wiki-links, UUID references, and frontmatter relationships.

/mnemonic:custodian validate-links [--fix] [--json]

With --fix: removes broken [[wiki-links]] from body text (replaces with plain text).

decay

Recalculate exponential decay strength values and update frontmatter in-place.

/mnemonic:custodian decay [--dry-run] [--json]

Formula: strength = current_strength * 0.5^(days_since_access / half_life_days)

Supports models: exponential, linear, step, none.

summarize

Find memories eligible for compression. Reports candidates for the compression-worker agent.

/mnemonic:custodian summarize [--dry-run] [--json]

Candidates: memories with >100 lines that are >30 days old OR have strength < 0.3.

To compress, invoke the mnemonic:compression-worker agent for each candidate.

validate-memories

Check memory frontmatter completeness against MIF schema.

/mnemonic:custodian validate-memories [--json]

Checks: required fields (id, type, title, created), UUID format, type enum, date format, confidence range, namespace/path consistency.

validate-relationships

Verify ontological relationship types and targets.

/mnemonic:custodian validate-relationships [--json]

Checks: relationship type validity (against MIF built-in + ontology custom types), target existence, strength range.

Options

• --dry-run - Preview changes without modifying files
• --fix - Auto-repair issues found (validate-links, audit)
• --json - Output report as JSON instead of markdown
• --commit - Git commit after changes are applied

Procedure

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(dirname $(dirname $0))}"
python3 "$PLUGIN_DIR/skills/custodian/lib/custodian.py" "$@"

If Python execution fails, fall back to manual execution of each subcommand using the skill guidance in skills/custodian/SKILL.md.

Examples

# Full health check (default)
/mnemonic:custodian

# Preview what audit would find
/mnemonic:custodian audit --dry-run

# Fix broken links and commit
/mnemonic:custodian validate-links --fix --commit

# Update all decay scores
/mnemonic:custodian decay --commit

# Move project memories after rename
/mnemonic:custodian relocate ${MNEMONIC_ROOT}/org/old-name ${MNEMONIC_ROOT}/org/new-name --commit

# JSON output for programmatic use
/mnemonic:custodian audit --json

Output

Displays a structured report with:

• Summary (total findings, errors, warnings, fixes applied)
• Errors grouped by category (links, frontmatter, relationships, decay)
• Warnings (orphans, namespace mismatches)
• Recommendations for follow-up actions
