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 | $0.00045 | $0.01330 |
| Opus 5 | $0.00023 | $0.00665 |
| Sonnet 5 | $0.00009 | $0.00266 |
| Haiku 4.5 | $0.00005 | $0.00133 |
Grade A, and why
builder-workflow 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 5d 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Builder workflow
Overview
Parent agent runs an approved .cursor/plans/<slug>.plan.md in phases — code and config only. The plan is the spec for build and verify; chat is for gates and short status.
This skill ends when the phase build is complete (checkup PASS, critical review addressed). It does not edit documentation tiers, commit, or open PRs.
After this skill: documentation-sync → git-pr-workflow. Full order: initiative-workflow.
REQUIRED: planning-workflow; verification-before-completion (superpowers cache).
Read AGENTS.md, this skill, and orchestration.md by path — never paste into child prompts.
Token discipline (non-negotiable)
| Rule | Parent | Subagent |
|---|---|---|
Plan in .cursor/plans/*.plan.md |
Path + phase excerpt ≤40 lines | Read phase section only |
| Every spawn | Goal / Context / Constraints / Done-when / Output | subagent-output-contract.md |
| Rules & skills | @ paths only |
Same |
| Scout returns | Merge task board; not full tables to user | Table ≤40 rows, checklist ≤12 |
| Checkup | model: composer-2-fast (required) |
PASS/FAIL; ≤80 lines failures |
| Implementers | Disjoint paths; no doc-tier files | ≤25 paths changed |
| User status | ≤12 lines per step | N/A |
Templates: prompt-templates.md
Build scope (in scope vs out)
| In scope (builder) | Out of scope — use later skills |
|---|---|
apps/, packages/, tools/ code, tests, configs |
docs/, root README.md, AGENTS.md |
| CI/docker/tsconfig/package.json (non-doc) | .cursor/skills/, .cursor/rules/ prose |
| Plan “Code/config surfaces” | Plan Documentation before PR → documentation-sync |
Exception: plan explicitly marks a docs-only phase — then builder skips code slices and user runs documentation-sync only.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-workflow is a skill published in the GitHub repository movahedan/monobun (18 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 1,330 once invoked, about $0.0002 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.
