realm-facts

realm-facts is a skill for Claude Code, Codex from blackmo18/realm. It costs 127 tokens per session (1,447 once invoked), scanned A, original, MIT.

A shared knowledge system for storing facts about a software project and making approved facts available to coding agents. It supports drafting, reviewing, linking, syncing, searching, and importing these facts.

In plain words
What is it for?
Use it to connect a repository to a central facts store, record domain knowledge, submit facts for GitLab review, notify Microsoft Teams, and retrieve facts during coding work.
Why use it?
It gives agents a maintained source of project knowledge instead of relying only on scattered files or repeated explanations.

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.

Security

Grade A, and why

realm-facts 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/facts.py, scripts/test_facts.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

realm-facts

Team knowledge facts, GitLab-reviewed, Teams-notified, agent-ingestable. Script owns state; LLM interviews and judges.

Host invocation: Claude Code and Gemini use /realm-facts; Codex uses $realm-facts. Resolve realmFactsSkillDir to the directory containing this SKILL.md; every fragment uses <realmFactsSkillDir>/scripts/facts.py and never assumes a host-specific install root.

Syntax

/realm-facts forge                              # connect this repo to a central facts repo
/realm-facts new <domain> <id>                   # interactively author a draft fact
/realm-facts link <id> --related <id2>           # relate two facts
/realm-facts submit <id>                         # branch + MR + Teams notify
/realm-facts review <id> [--approve | --request-changes "..."]
/realm-facts sync                                # pull latest approved facts
/realm-facts recall <query>                      # search facts
/realm-facts ingest <id> [--bundle impl|context|full]  # FACT_BUNDLE for coding agents

When to Use

Trigger Example
First time in this repo "connect facts", /realm-facts forge
Document a team decision/behavior /realm-facts new platform jwt-token-rotation
Relate two facts /realm-facts link jwt-token-rotation --related session-refresh-policy
Ready for team review /realm-facts submit jwt-token-rotation
Asked to review a fact MR /realm-facts review jwt-token-rotation
Pull latest after Teams approval notice /realm-facts sync
"What do we know about X?" /realm-facts recall jwt
Hand a fact to a coding agent /realm-facts ingest jwt-token-rotation --bundle impl

When NOT to Use

  • Querying this project's own architecture/ADR history → /realm-recall (different store: vault, not facts repo)
  • Investigating live code behavior → /realm-fathom
  • No facts repo connected yet → /realm-facts forge first (every other subskill guards on this)

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.
