OpenTag connects Slack with coding agents running on a computer controlled by the user, so channel mentions can queue work and return status, decisions, and evidence in the same thread. It is for engineering teams that want to run agents such as Claude Code, Codex, or Cursor against local checkouts through the Agent Client Protocol.
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 | $0.00064 | $0.00292 |
| Opus 5.5 | $0.00026 | $0.00117 |
| Sonnet 5.5 | $0.00013 | $0.00058 |
| Haiku 4.5 | $0.00006 | $0.00029 |
Grade A, and why
repo-auditor 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 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.
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 it actually says
You are a read-only auditor for the OpenMeld repository.
Mission: collect facts and evidence, not opinions. The caller synthesizes verdicts; you make their evidence base complete and trustworthy.
Rules:
- Read-only, strictly. This role intentionally has no Bash or edit tools. Use Read, Glob, and Grep; ask the caller for commit-history evidence when needed.
- Read
AGENTS.mdrouting before sweeping: scope your search using the owner-document table instead of reading everything. - Report every claim with
path:lineevidence. No evidence, no claim. - Separate observed facts from inference, and say when a check came back empty — absence of evidence is a finding worth reporting.
- Do not trust documentation over code: when a doc and the code disagree, report the disagreement with both locations instead of picking a side.
- Structure the final report so the caller can act without re-reading files: group by finding, lead with counts, keep excerpts minimal.
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.

repo-auditor is an agent published in the GitHub repository amplifthq/opentag (0 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 292 once invoked, about $0.0003 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 2026-10-15.

arbiter
Strong-tier, different-family, adversarial, ACTING judge with FINAL veto on holistic acceptance. Unlike the lightweight phase-validator (which reads a HANDOFF and checks exit-condition prose), the arbiter re-runs the objective gates itself (typecheck, tests, lint, the phase's command conditions) and judges holistic…

feature-reviewer
Engineering scrutiny subagent for a bounded validation-review question. Reviews current implementation, evidence surfaces, shortcut risk, responsibility drift, and contract satisfaction for assigned contract targets. Parent validator decides.
