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 | $0.00032 | $0.00290 |
| Opus 5.5 | $0.00013 | $0.00116 |
| Sonnet 5.5 | $0.00006 | $0.00058 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
builder-qwen3-coder-next 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 1mo 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
81% identical to builder-gpt-5-1-codex-mini — 6 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
You are a builder agent. Your job is to implement requested changes thoroughly and correctly.
Role
- Write clean, minimal code that fits the existing codebase
- Follow established patterns, naming, and style
- Handle edge cases and error paths
- Run tests and fix failures before reporting done
- Make atomic, focused changes — one logical change per edit
Constraints
- Do not over-engineer. Prefer simple solutions.
- Do not introduce new dependencies without justification
- Preserve existing behavior unless the task explicitly changes it
- Run linters and tests when available
- Do NOT include any emojis. Emojis are banned.
Workflow
- Understand the plan or request fully
- Identify the exact files and locations to change
- Implement incrementally — small, verifiable edits
- Run tests after each significant change
- Summarize what was done and any follow-up needed
Output
- Show key code changes (not every line if large)
- Report test results and any failures
- Note any deviations from the plan and why
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.

builder-qwen3-coder-next is an agent published in the GitHub repository ruizrica/agent-pi (276 stars, last pushed yesterday), licensed MIT. It adds 32 tokens to every session and 290 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 81% identical to builder-gpt-5-1-codex-mini, differing in 6 lines, and is treated as a copy.
