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 | $0.00000 | $0.24780 |
| Opus 5 | $0.00000 | $0.12390 |
| Sonnet 5 | $0.00000 | $0.04956 |
| Haiku 4.5 | $0.00000 | $0.02478 |
Grade B, and why
_shared-rules scanned grade B with 3 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 yesterday.
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.
- **Availability probe is `--probe`, not `--version`.** There is no binary: `xai_client.py --probe` exits 0 when it resolves `XAI_API_KEY`, 1 otherwise. Resolution checks the process environment first, then `~/.claude/se Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Vision/OCR via the CLI is unreliable** — it may not pass an image as a true vision input and frequently refuses outright ("I cannot perform OCR for handwriting"). For any image task, **bypass the CLI and call the RES Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

_shared-rules is a command published in the GitHub repository OpenCairn/OpenCairn (5 stars, last pushed 8d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 24,780 tokens. A static security scan graded it B with 3 findings (reads agent configuration directories, makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

canvas
AI-orchestrated visual canvas production — create, populate, layout, present, generate, and export Obsidian canvases.
ingest
Ingest a source (URL/file/text) into Raw Sources + compile 1015 Wiki pages, with mandatory user-purpose gate and mothership cross-linking.
audit
Audit the whole Wiki vault against 3 knowledge-integrity criteria — eligibility coverage, MOC-cluster consistency, confidence calibration. Produces a vault health report and queues high-priority pages for /verify.
verify
Verify a single Wiki page against 3 knowledge-integrity criteria — eligibility, consistency, confirmability. Writes verificationStatus back to the page; flags conflicts as disputed rather than deleting them.
lint
Run comprehensive wiki health check — orphans, broken links, contradictions, stale pages, index sync, MOC coverage, v2/v4/v5 frontmatter coverage, Core Context freshness, and cross-vault link integrity (mainVaultRelated/mainVaultCmds).
