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: 1 finding, up to high
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 | $0.00042 | $0.00469 |
| Opus 5 | $0.00021 | $0.00234 |
| Sonnet 5 | $0.00008 | $0.00094 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
isomux-second-opinion scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
If a peer name was supplied, look up their agent ID via the agent manifest: `curl -s localhost:4000/agents -H "Authorization: Bearer $ISOMUX_AGENT_TOKEN"` (4000 is the default isomux server port; adjust if your office ru What it actually says
Ask a peer agent for a second opinion on a specific question - a design decision, an approach, a fork in the road. The peer replies once with their take and you keep driving.
Syntax: /isomux-second-opinion {peer-agent-name} {optional question}
1. Pick the peer
If a peer name was supplied, look up their agent ID via the agent manifest: curl -s localhost:4000/agents -H "Authorization: Bearer $ISOMUX_AGENT_TOKEN" (4000 is the default isomux server port; adjust if your office runs on a different one). Match the name case-insensitively. Otherwise try to infer the peer from context - e.g., an agent the boss and you have already paired or consulted with in this session. If there's a clear inference, use it (and briefly confirm who you picked). Otherwise, list candidates (prefer agents whose cwd matches yours) and ask the boss to pick. You need the peer's agent ID to POST messages to them.
2. Frame the question
If the boss supplied a question, use it verbatim. Otherwise pin down one concrete thing you want an opinion on.
3. Send the ask
POST to /agents/<peer-id>/message. The body must include:
- The question, framed clearly.
- Just enough context to form an opinion: the specific code path or decision, relevant constraints.
- What you want from them: a concrete recommendation with reasoning. Not approval - you're not asking for permission.
- How to reply: they must POST back to your agent endpoint, not type in their own chat. Give them your agent ID explicitly.
- That they're advisory only - you're staying on the work.
4. Confirm and continue
Tell the boss you've sent the ask and to whom. You can keep working on parts of the task that aren't blocked by the open question. When the peer's reply arrives, integrate it into your next decision.
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.

isomux-second-opinion is a skill published in the GitHub repository nmamano/isomux (37 stars, last pushed yesterday), licensed MIT. It adds 42 tokens to every session and 469 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
