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 | $0.00009 | $0.00543 |
| Opus 5 | $0.00005 | $0.00271 |
| Sonnet 5 | $0.00002 | $0.00109 |
| Haiku 4.5 | $0.00001 | $0.00054 |
Grade B, and why
list scanned grade B with 1 finding 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 2d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Search first: /mnemonic:search {relevant_keywords}
Capture after: /mnemonic:capture {namespace} "{title}"
Run /mnemonic:list --namespaces to see available namespaces from loaded ontologies.
List Ontologies
Lists all loaded ontologies with their namespaces and entity types.
Usage
/mnemonic:list [--namespaces] [--types] [--json]
Options
--namespaces- Show only namespaces--types- Show only entity types--json- Output as JSON
Procedure
# Find and run the ontology registry from the plugin directory
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$(dirname $(dirname $0))}"
python3 "$PLUGIN_DIR/skills/ontology/lib/ontology_registry.py" ${ARGS}
Flag mapping:
/mnemonic:list→python3 ... --list/mnemonic:list --namespaces→python3 ... --namespaces/mnemonic:list --types→python3 ... --types/mnemonic:list --json→python3 ... --json
If the Python script is not available, use the Read tool to display ontology files:
# Read base ontology
cat "${PLUGIN_DIR}/skills/ontology/fallback/ontologies/mif-base.ontology.yaml" 2>/dev/null
# Read project ontology
cat ".claude/mnemonic/ontology.yaml" 2>/dev/null
# Read user ontology
cat "$HOME/.claude/mnemonic/ontology.yaml" 2>/dev/null
Example Output
Loaded ontologies:
- mif-base v1.0.0
Namespaces: semantic/, _semantic/decisions, _semantic/knowledge, _semantic/entities,
episodic/, _episodic/incidents, _episodic/sessions, _episodic/blockers,
procedural/, _procedural/runbooks, _procedural/patterns, _procedural/migrations
Traits: timestamped, confidence, provenance
Relationships: relates_to, supersedes, derived_from
- software-engineering v1.0.0 (extends mif-base)
Entity types: component, architectural-decision, incident-report, technology
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.
- 2d ago First seen · 77 lines · 9 tokens per session scan B 3f0520ad9287
list is a command published in the GitHub repository modeled-information-format/mnemonic (22 stars, last pushed 1mo ago), licensed MIT. It adds 9 tokens to every session and 543 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
