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 | $0.00102 | $0.02351 |
| Opus 5 | $0.00051 | $0.01175 |
| Sonnet 5 | $0.00020 | $0.00470 |
| Haiku 4.5 | $0.00010 | $0.00235 |
Grade A, and why
mk:autobuild 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.
How it starts
The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
mk:autobuild — Autonomous Multi-Hour Build Orchestration
Step-file workflow that runs the complete generator/evaluator harness pipeline as an autonomous build. Handles green-field product builds (planner stage → contract stage → evaluator loop → ship decision) with adaptive scaffolding density based on detected model tier.
When to Use
Activate when:
- User runs
/mk:autobuild "build a X"(or any green-field product description) - Existing kit detection routes a green-field "build me an app" intent here instead of
mk:cook - A multi-hour autonomous build is requested with no manual handholding
Skip when:
- The task is a single feature, bug fix, or refactor → use
/mk:cookinstead - The task is a doc update → use the existing doc skills
- The request is "explain X" or "review Y" → use the appropriate single-shot skill
Hard Constraints
- Adaptive density — picks scaffolding density via
mk:scale-routing(ordensity-select.sh); honorsMEOWKIT_AUTOBUILD_MODEenv override - Budget caps — warns at $30 spent, requires explicit approval at $100, hard-blocks at user-set
--budgetvalue - 6-hour wall-clock timeout — hard limit per Anthropic's observed runs ; checkpoints every step for resumability
- Max 3 iteration rounds between generator and evaluator before escalating to human (configurable via
--max-iter) - Run report mandatory — every autobuild run produces
tasks/autobuild-runs/YYMMDD-{slug}/run.mdwith full audit trail - Coexists with
mk:cook— does not replace it; both route through Gate 1 + Gate 2 - TDD opt-in (parallel to cook): autobuild respects
--tddlike other flows. Default: no RED-phase gate. With--tdd: writes the.claude/session-state/tdd-modesentinel and the developer waits on tester before each generator iteration. Active-verification HARD GATE (Rule 8 ofharness-rules.md) is independent of TDD mode and always applies.

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.

mk:autobuild is a skill published in the GitHub repository ngocsangyem/MeowKit (14 stars, last pushed 1mo ago), licensed MIT. It adds 102 tokens to every session and 2,351 once invoked, about $0.0005 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.
