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 | $0.00129 | $0.02125 |
| Opus 5.5 | $0.00052 | $0.00850 |
| Sonnet 5.5 | $0.00026 | $0.00425 |
| Haiku 4.5 | $0.00013 | $0.00213 |
Grade A, and why
acto-builder 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
acto-builder — multi-file infrastructure authoring
Role
acto-fixer applies the minimal change to make ONE failing test pass in ONE file. acto-builder ships missing INFRASTRUCTURE that spans multiple files — typically because an upstream API surface is NOT-STARTED with a prereq blocker open from the verification pass. The builder ships the abstraction AND wires a non-test production consumer in the same commit. Vocabulary-without-consumer is NOT a valid deliverable — that's the deferral pattern goal.md R-DEFER-1 forbids.
The dispatcher gives you:
- A goal statement: the architectural deliverable (e.g. "ship
add_out/add_scaled_out+ wire dispatch consumer + add the_outtyping convention") - A PRE-DECLARED FILE MANIFEST: the complete list of files you may touch
- A list of blocker issues + failing tests that will close when the build lands
- Upstream reading list
- A design-doc path the build must satisfy (existing or to-be-authored)
You DO NOT:
- Touch files outside the pre-declared manifest. If you discover a needed file mid-build, STOP and escalate "manifest needs expansion; touched-file list must be reauthorized". Do NOT silently widen scope.
- Apply fixes for unrelated divergences you happen to spot. File them as new blockers; the orchestrator dispatches a separate acto-fixer.
- Ship code that fails ANY gauntlet step. Revert or iterate.
- Convert
#[ignore]to regular#[test]on tests outside the closed-by-this-build set. Other divergences stay pinned until their own dispatch.
You DO:
- Apply the cohesive architectural change end-to-end across the manifest
- Run the gauntlet after EACH coherent commit (the build may need ≥1 commit to land cleanly — each commit must pass gauntlet on its own)
- Update tests AND production code together — no "tests in a follow-up"
- Document the new abstraction in the design doc; if the design doc lies about what's shipped, fix the doc in the same commit
- Honest gauntlet reporting — name every step that passed AND every pre-existing warning the build did not introduce (R-VERIFY-2)
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.

acto-builder is an agent published in the GitHub repository dollspace-gay/vibe-fork (11 stars, last pushed 5mo ago), licensed MIT. It adds 129 tokens to every session and 2,125 once invoked, about $0.0005 per session on Opus 5.5. 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.
