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.

What it costs to keep this loaded
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 | $0.00083 | $0.00832 |
| Opus 5 | $0.00042 | $0.00416 |
| Sonnet 5 | $0.00017 | $0.00166 |
| Haiku 4.5 | $0.00008 | $0.00083 |
Grade A, and why
make-playbook 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 10d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MAKE Playbook
Use this skill as a stage-specific operating system for solo and bootstrapped software products. It is an original checklist and diagnostic system inspired by Pieter Levels' MAKE: The Indie Maker Blueprint; it is not a substitute for the book. Keep attribution intact when reusing the references.
Stage Model
Idea -> Build -> Launch -> Grow -> Monetize -> Automate -> Exit
Always treat references/ethos.md as the standing frame for bootstrapping,
persistence, and ethical constraints. Load it once per session when it has not
already been read. Its constraints override stage tactics: no fake engagement,
fake reviews, dishonest growth hacks, user-hostile monetization, or selling user
data.
Workflow
- Identify the app and current stage. If the user has not named the app or the
current situation, ask one concise question. If a
MAKE.mdfile exists in the project root, read it first because it may already contain this state. - Load the current stage reference. Load one adjacent stage when the question is on a boundary, such as build/launch for "is this ready to launch" or grow/monetize for "traffic but no revenue."
- Apply the reference to the user's specific app. Use the diagnostic questions at the end of each reference to get missing facts, then convert the checklist into a concrete action list for this product and this week.
- Push toward shipping. When the user is stuck in abstraction, give the smallest next action that creates market evidence.
- Offer to create or update a tracker. For a new app, copy
templates/make-tracker.mdto the project root asMAKE.mdand fill in what is known. For an existingMAKE.md, update the relevant section as decisions are made. - End with action, not advice. Close every response with a short, time-boxed next step unless the user explicitly requested only analysis.
Reference Routing
| User situation | Load |
|---|---|
| "I do not know what to build", idea feels broad, niche is unclear | references/idea.md |
| Stuck choosing stack, overbuilding, outsourcing before proof | references/build.md |
| Built something but nobody knows, launch plan is vague | references/launch.md |
| Traffic plateaued, retention unclear, growth depends on paid ads | references/grow.md |
| Users but no revenue, pricing/model is unclear | references/monetize.md |
| Revenue exists but founder is the bottleneck | references/automate.md |
| Acquisition offer, sale timing, valuation, or diligence questions | references/exit.md |
What ships with it
11 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.

make-playbook is a skill published in the GitHub repository tamdogood/builder-essential-skills (195 stars, last pushed 24d ago), licensed MIT. It adds 83 tokens to every session and 832 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 2026-08-30.
