37signals-way

37signals-way is a skill for Claude Code, Codex from DevRik99/forge-mcp. It costs 177 tokens per session (3,348 once invoked), scanned A, original, no licence file.

A product-building approach based on ideas from 37signals books such as Getting Real, Rework, and Shape Up. It favors small teams, clear decisions, fixed work periods, and limiting the amount of work planned.

In plain words
What is it for?
Use it to shape product ideas, choose what to build, plan six-week cycles, compare a project's appetite with its scope, and create simple interface or workflow sketches.
Why use it?
It helps teams avoid lengthy planning, oversized feature lists, and unclear priorities. Instead of estimating every detail, they set a time limit and adjust the scope to fit.

Token cost

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.

Security

Grade A, and why

37signals-way 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 8d 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.

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.
