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 | $0.00059 | $0.01564 |
| Opus 5 | $0.00030 | $0.00782 |
| Sonnet 5 | $0.00012 | $0.00313 |
| Haiku 4.5 | $0.00006 | $0.00156 |
Grade A, and why
multi-agent 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 2d 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.

Multi-Agent Orchestration
You are orchestrating a task across a team of AI agents. Each team member has a role, a provider, and a model. You dispatch sub-tasks to the right model, collect results, and produce a unified output.
How It Works
When the user provides a task, follow this flow:
Phase 1 — Define the Team
If the user provides a team definition, use it. If not, propose a default team based on the task type. The team definition is a list of agents:
team:
- role: planner
provider: anthropic
model: claude-opus-4-20250514
task: "Analyze the request and produce a structured plan with clear steps, dependencies, and risks."
- role: executor
provider: openrouter
model: google/gemini-2.5-pro
task: "Execute each step of the plan. Write code, make changes, run commands."
- role: auditor
provider: xiaomi
model: mimo-v2-omni
task: "Review all changes for correctness, security, style, and completeness. Report issues."
Present the team to the user for confirmation before proceeding. The user can:
- Change providers/models for any role
- Add or remove roles
- Adjust the task description for each role
- Skip confirmation with "go" or "just do it"
Phase 2 — Execute Sequentially
Run each agent in order. For each agent:
-
Switch model: Use
/models <provider>/<model>or the config to set the active model to the agent's provider+model combination. -
Dispatch the task: Send the agent's
taskas a prompt, along with:- The original user request
- Any output from previous agents (context handoff)
- Specific instructions for this phase
-
Collect output: Capture the full response. This becomes input for the next agent.
-
Log progress: Report to the user which phase just completed and a 1-line summary.
Phase 3 — Synthesize
After all agents have run:
- Combine all outputs into a coherent result
- Highlight any conflicts or issues found by the auditor
- Present a final summary with:
- What was planned (planner output)
- What was done (executor output)
- What was found (auditor output)
- Final recommendation
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.

multi-agent is a skill published in the GitHub repository adolfousier/opencrabs (916 stars, last pushed 3d ago), licensed MIT. It adds 59 tokens to every session and 1,564 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.

compare-harnesses
Diff two scaffolded harnesses (ADR-031). Reports manifest meta drift + host list + per-file fingerprint changes (added/removed/changed). Exits 0 IDENTICAL, 1 DRIFT, 2 missing manifest. Use --bundle for the ADR-031 schema-1 JSON envelope.
oia-manifest
Emit .harness/oia-manifest.json declaring layer alignment with the OIA v0.1 9-layer reference architecture. Self-describes the harness's MCP wiring, witness signing, audit log, identity posture (always 'none' at v0.1). --check verifies an existing manifest, --dry-run prints without writing, --json emits to stdout.
create-harness
Scaffold your own focused AI agent harness — pick host (Claude Code, Codex, pi.dev, Hermes), template, agents, skills, and ship a npm-publishable harness with its own npx CLI. Use when a user asks to "create my own agent harness", "scaffold a harness", "make a custom Claude Code plugin like ruflo", or "build a…
diag-harness
Kernel-version skew check (ADR-027). Reports manifest surface + manifest kernel + installed kernel + verdict (match/patch-diff/minor-diff/major-diff). Exits 1 on minor/major skew with a copy-pasteable npm install @metaharness/[email protected] next step. Exits 2 if no .harness/manifest.json at path.
