A knowledge and codebase memory skill that extracts information from documents, searches code structure, and stores operational notes for later use.

Use it to index documents, inspect code symbols and call relationships, retrieve evidence, and preserve useful project memories.

It helps an agent find relevant specifications, code relationships, and earlier decisions without relying only on the current conversation.

Token cost

What it costs to keep this loaded

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	$0.00060	$0.02645
Opus 5	$0.00030	$0.01323
Sonnet 5	$0.00012	$0.00529

Security

Grade A, and why

ogm scanned grade A 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 12d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

OpenGraphMemory (OGM) Skill

This skill provides a comprehensive, unambiguous, production-grade operational guide for AI Agents interacting with OpenGraphMemory (OGM). It covers all three core capabilities: Document Knowledge Graphs, Codebase AST Call-Graphs, and Persistent Agent Operational Memory.

🎯 Task Intent Routing (English & Indonesian Triggers)

Default to using OGM whenever a task involves reading documents, navigating codebases, or executing non-trivial engineering/operational work.

📄 Category 1: Document Upload & Knowledge Extraction

English Triggers:

"Upload/index document spec.pdf or design.md into OGM"
"Extract knowledge graph from document X"
"Show evidence quotes for relation Y"

Indonesian Triggers:

"Upload/index dokumen spec.pdf ke OGM"
"Extract knowledge graph dari dokumen design.md"
"Tampilkan bukti kutipan relasi Y"

Action Protocol:

Identify dataset (ogm_list_datasets).
Upload document using ogm_upload_document.
Inspect relation evidence quotes using ogm_get_evidence or ogm_get_relation_evidence.

💻 Category 2: Codebase AST Call-Graphs & Centrality

English Triggers:

"Extract/index this codebase into OpenGraphMemory / OGM"
"Build AST call-graph for project Y"
"Which symbols are most connected / have top degree in repo Z?"

Indonesian Triggers:

"Tolong extract codebase ini ke dalam knowledge graph menggunakan ogm"
"Index repo ini ke dalam OGM"
"Simbol apa yang paling banyak keterhubungannya / urutkan degree terbanyak"

Action Protocol:

Full Repo Onboarding (Oneshot): Call ogm_index_codebase with dataset_id and path.
Incremental Single-File Edit: Call ogm_sync_code_file when editing 1 file during pair programming.
Symbol Search & Call Graphs: Use ogm_search_code_symbols and ogm_get_code_call_graph.
Degree Centrality Ranking: Use ogm_get_code_chunks to fetch hub nodes sorted by degree.

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.

ogm is a skill published in the GitHub repository ardiannurcahya/ogm-mcp-skills (6 stars, last pushed 29d ago), licensed MIT. It adds 60 tokens to every session and 2,645 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
