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 5.1 | $0.00057 | $0.00593 |
| Opus 5 | $0.00028 | $0.00296 |
| Sonnet 5 | $0.00011 | $0.00119 |
| Haiku 4.5 | $0.00006 | $0.00059 |
Grade A, and why
build-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 8d 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.
This is a copy
100% identical to build-agent — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
build-agent - lab-scoped draft agent bootstrap
Use this skill when the user enters /build-agent <name> in a lab chat
composer and intends to start defining a new agent inside the current lab.
A1 behavior
The A1 command is intentionally small:
- Read the agent name from the command text.
- Create a draft agent record scoped to the current lab.
- Open the lab-scoped agent detail route:
/labs/<lab_id>/agents/<agent_id>
The created record is a placeholder for future builder steps. Treat its config as an editable draft, not as a runnable or published agent.
Required scope
- The command must run from an active lab context.
- The created agent must carry the current lab id.
- Lists and detail views must stay under that lab.
- A user without access to the lab must not be able to see or create records for that lab.
Non-goals in A1
- No actual agent build pipeline.
- No run, evaluation, gauntlet, battleground, or publish workflow.
- No observability integration.
- No deployment orchestration.
- No global agents surface; agent records are reached from the owning lab.
Operator response
After the draft is created, keep the response minimal: name the draft and open the lab detail route. Do not imply the agent has been built, tested, deployed, or connected to runtime infrastructure.
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.

build-agent is a skill published in the GitHub repository Rockielab/rockie-codex (20 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 57 tokens to every session and 593 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to build-agent, differing in 0 lines, and is treated as a copy.
