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 | $0.00069 | $0.00350 |
| Opus 5.5 | $0.00028 | $0.00140 |
| Sonnet 5.5 | $0.00014 | $0.00070 |
| Haiku 4.5 | $0.00007 | $0.00035 |
Grade A, and why
build-master-control-plane 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.
What it actually says
Build Master Control Plane Skill
Use this skill to design and run a safe background merge control plane with a paired cloud break-fix worker.
Reference Files
| File | Purpose |
|---|---|
references/state-machine.md |
Lane/global state definitions and transitions |
references/policy-matrix.md |
Break-fix eligibility, retry budgets, and escalation thresholds |
Workflow
- Map PRs into lanes and assign risk tiers.
- Merge serialized per lane only when pre-merge policy gates are green.
- Detect and classify post-merge failures by lane and blast radius.
- Dispatch cloud break-fix worker only for allow-listed low/medium-risk failures.
- Keep healthy lanes moving while pausing impacted lanes by policy.
- Resume paused lanes only after fix PR verification and policy checks.
- Escalate to blocking issue/global hold when thresholds are exceeded.

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.

build-master-control-plane is a skill published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed 13d ago), licensed MIT. It adds 69 tokens to every session and 350 once invoked, about $0.0003 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 2026-09-03.
