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 | $0.00054 | $0.01079 |
| Opus 5 | $0.00027 | $0.00540 |
| Sonnet 5 | $0.00011 | $0.00216 |
| Haiku 4.5 | $0.00005 | $0.00108 |
Grade A, and why
compose-agent 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 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.
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.

Compose Agent — Assembly and Wiring
Take existing components (skills, workflows, SOUL.md, backend config) and wire them into a complete, runnable agent.
When to Use
- User has standalone skills and wants to bundle them into an agent
- User wants to add a skill or workflow to an existing agent
- User wants to change an agent's backend, model, or tool permissions
- User wants to fork an existing agent for a different domain
Process
Step 1: Inventory
Discover what exists:
-
Check for existing agents:
Find directories matching: agents/*/AGENT.yaml -
Check for standalone skills:
Find files matching: skills/*/SKILL.md -
Check for standalone workflows:
Find files matching: workflows/*.yaml -
Check dispatch backends:
Read ~/.config/ai-dispatch/config.json for available backends
Present the inventory to the user.
Step 2: Select Components
Ask the user:
-
Base: "Start from scratch or fork an existing agent?"
- If forking: copy the agent directory and modify
-
Skills: "Which skills should this agent include?"
- List available skills with descriptions
- Allow selecting existing or noting new ones to create
-
Workflows: "Does this agent need workflow enforcement?"
- List available workflows
- Allow selecting existing or noting new ones to create
-
Backend: "Which backend should it use?"
- List available dispatch backends
- Default, specific provider, or multi-backend routing
-
Identity: "Keep/modify the SOUL.md or create new?"
Step 3: Assemble
Create or update the agent directory:
If creating new:
agents/<name>/
├── SOUL.md
├── AGENT.yaml
├── skills/
│ ├── <skill-1>/SKILL.md ← copy or symlink
│ └── <skill-2>/SKILL.md
├── workflows/
│ └── <workflow>.yaml ← copy or symlink
└── memory/
If modifying existing:
- Read current AGENT.yaml
- Add/remove skills from the skills list
- Add/remove workflows from the workflows list
- Update configuration as needed
- Validate any new workflow files
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.

compose-agent is a skill published in the GitHub repository gettalon/talon-plugins (6 stars, last pushed 5mo ago), licensed MIT. It adds 54 tokens to every session and 1,079 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
