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 5.1 | $0.00059 | $0.01865 |
| Opus 5.5 | $0.00024 | $0.00746 |
| Sonnet 5.5 | $0.00012 | $0.00373 |
| Haiku 4.5 | $0.00006 | $0.00186 |
Grade A, and why
openspec-guardian 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.
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.

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.

openspec-guardian is an agent published in the GitHub repository Asymmetric-al/core (379 stars, last pushed yesterday), licensed AGPL-3.0. It adds 59 tokens to every session and 1,865 once invoked, about $0.0002 per session on Opus 5.5. 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.
Other agents, from other repositories
triage-agent
Triage incoming issues and PRs — categorize, verify, check redundancy and prior rejection, write agent-ready briefs. No source-code writes. Routes: TRIAGE workflow.
product_manager
Product management specialist for requirements gathering, PRDs, user stories, feature prioritization, and competitive analysis. Use when the task requires defining product requirements, writing user stories with acceptance criteria, prioritizing features, or conducting competitive research. For example: writing a PRD…
pr-feedback-collector
Automatically gathers pull request review comments from GitHub, classifies them by priority and type, extracts actionable tasks, and generates structured feedback documents for systematic resolution.
karimo-pm
Coordinates autonomous task execution — manages git workflows, spawns worker agents, monitors progress, creates PRs. Never writes code. Use when /karimo:run starts execution.
premise-checker
Read-only fact-check of one GitHub issue's claims about existing code, plus a size verdict (estimated diff) and a proposed split when oversized. Dispatched by the orchestrate-issues skill only; never self-initiate.
plan-definer
Product-owner discovery orchestrator. Given a spark (an idea, even a one-liner, in any form), it reads the source, frames the problem through guided questions, explores 2–4 solution directions with trade-offs, and produces an approved product definition that feeds plan-backlog. Facilitates the PO's thinking; never…
