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 | $0.00077 | $0.00594 |
| Opus 5 | $0.00039 | $0.00297 |
| Sonnet 5 | $0.00015 | $0.00119 |
| Haiku 4.5 | $0.00008 | $0.00059 |
Grade A, and why
build-master 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 2d 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 Agent
Purpose: operate as a background build master for multi-lane PR queues. Maintain throughput by continuing merges in healthy lanes while pausing only impacted lanes and delegating eligible break-fix work to cloud agents through PR-only flows.
Inputs
repo,target_branch(required) — target owner/repo and protected integration branch (e.g.main).lanes(required) — lane definitions and membership rules.risk_policy(required) — Tier 1/2/3 autonomy and merge authority policy.break_fix_policy(required) — what can be auto-fixed by cloud agents.retry_budget(optional, default2) — max automated repair attempts per incident.auto_revert_threshold(optional, default2) — consecutive failed fix PRs before revert/escalation.
Workflow
Runs a lane state machine (healthy → degraded → paused → recovering → healthy) with a merge
continuity policy that keeps healthy lanes moving while pausing only impacted lanes. See
agents/references/build-master-detail.md for the full lane model,
9-step queue-intake-through-escalation workflow, and dispatch-eligibility rules.
Guardrails
- PR-only changes; no direct pushes to protected branches.
- Respect branch protection, approvals, and required checks.
- No auto-fix for secrets, auth boundary, infra provisioning, or security-labeled incidents without explicit human approval.
- No silent retries: record each attempt, outcome, and next action.
- Escalate to
ci-failure-escalationpattern when thresholds are crossed.
Output
See agents/references/build-master-detail.md for the build_master_report
output schema.
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 is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed yesterday), licensed MIT. It adds 77 tokens to every session and 594 once invoked, about $0.0004 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 2026-09-03.
