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.

SkillSpector: 6 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00039 | $0.03278 |
| Opus 5 | $0.00019 | $0.01639 |
| Sonnet 5 | $0.00008 | $0.00656 |
| Haiku 4.5 | $0.00004 | $0.00328 |
Grade A, and why
command-authoring 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 9d 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.
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 — 245 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Command Authoring
Reference for authoring and auditing slash commands across CC, Codex, and Gemini. Commands are L4 (Instructions) artifacts in the COC 5-layer architecture per rules/cc-artifacts.md — distinct from agents (L1 Intent), skills (L2 Context), and rules (L3 Guardrails). They inject as user-message prompts at invocation; every line competes with actual user intent for context.
When To Use
Authoring a new slash command. Auditing an existing command for line cap, neutral phrasing, native-primitive carve-out drift, or cross-CLI parity. Deciding whether work belongs in a command (procedure invoked by name) versus an agent (specialist judgment + tools) or a skill (reference looked up on demand).
Quick Reference

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.
- 9d ago First seen · 245 lines · 39 tokens per session scan A 98faf9678bc3
command-authoring is a skill published in the GitHub repository terrene-foundation/kailash-coc-claude-py (12 stars, last pushed 24d ago), licensed Apache-2.0. It adds 39 tokens to every session and 3,278 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
