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 | $0.00024 | $0.00289 |
| Opus 5 | $0.00012 | $0.00144 |
| Sonnet 5 | $0.00005 | $0.00058 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
add-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.
What it actually says
Agents extend src/agents/base.ts. Copy from the simplest existing
agent (src/agents/reviewer.ts or src/agents/debugger.ts).
Steps
src/agents/<name>.ts— extend base. Declare:- allowed tool set (narrow, not "all tools"),
- model preferences (router falls back if unavailable),
- system prompt (short — it's paid for every turn).
- Register in
src/agents/registry.ts. - Unit test — mock
callModel(seetest/unit/executor-loop.test.ts). Cover:- the agent only calls the tools it declared,
- a failing tool call is surfaced as a structured error, not a throw,
- turn caps from
src/core/mode-policy.tsare respected.
- Docs — update the agent list in
docs/ARCHITECTURE.mdif user-visible.
Invariants you cannot break:
- Do not widen the allowed tool set to "all tools" to make a test pass.
- Do not bypass
src/core/validation.ts. - Do not call the model directly — always go through router/adapter.
Finish with the verify skill.
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.

add-agent is a skill published in the GitHub repository hoangsonww/Forge-Agentic-Coding-CLI (22 stars, last pushed 16d ago), licensed MIT. It adds 24 tokens to every session and 289 once invoked, about $0.0001 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 2026-08-30.
