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 | $0.00050 | $0.00596 |
| Opus 5 | $0.00025 | $0.00298 |
| Sonnet 5 | $0.00010 | $0.00119 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
isomux-pair-programming 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 3d 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.

Pair-program a feature with another agent. You drive, they review.
Syntax: /isomux-pair-programming {peer-agent-name} {feature prompt}
Setup: 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. Work in the current cwd unless the boss explicitly asks for a worktree.
Every time you message the peer, include an explicit instruction telling them they must reply by POSTing back to your agent endpoint, not just by writing in their own chat. Replies that only appear in their own chat never reach you, so the iteration stalls.
Phase 1: scope (solo)
Scope the feature end-to-end by yourself. Read the relevant code, understand what touches what, and gather the context needed to design it. Don't loop in the peer yet. When done, auto-advance to Phase 2.
Phase 2: design (with peer)
Before writing any code, send the peer a short plan: files touched, approach, key edge cases. Ask for feedback.
Iterate. Stop and escalate to the boss with both positions summarized if either:
- you reach 5 rounds without convergence, or
- the decision involves architectural tradeoffs that affect other parts of the system.
Otherwise, once aligned, auto-advance to Phase 3.
Phase 3: implementation (with peer review)
Implement the feature. Then ask the peer to review the diff (point them at the cwd if they share it, or share the diff inline). Tell them their goal is to uphold code quality and principled architecture.
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-pair-programming is a skill published in the GitHub repository nmamano/isomux (37 stars, last pushed 4d ago), licensed MIT. It adds 50 tokens to every session and 596 once invoked, about $0.0003 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.
