pm-tech-scope

pm-tech-scope is a skill for Claude Code, Codex from joinwell52-AI/CodeFlowMu-open. It costs 76 tokens per session (470 once invoked), scanned A, original, MIT.

A planning guide for choosing the smallest suitable technology stack for a development task.

In plain words
What is it for?
Use it before assigning development work to decide the language, runtime, framework, environment, deliverable format, and when the developer must ask for guidance.
Why use it?
It prevents unnecessary frameworks, languages, build tools, or services from being added when a simpler option will work.

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

pm-tech-scope 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 5d 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

PM Tech Scope

When to use

Use this skill before PM dispatches a development task whose implementation language, runtime, framework, build chain, or delivery format is not already obvious from the target project.

Rules

  • Do not infer the target task stack from the host repository stack.
  • Choose the smallest appropriate stack for the requested deliverable.
  • Prefer static HTML/CSS/JS for standalone browser games, demos, prototypes, and simple interactive pages.
  • Prefer Python for automation, data processing, scripts, CLIs, local tooling, AI/ML workflows, quick backend utilities, and glue code.
  • Prefer TypeScript for existing TypeScript projects, long-lived frontend apps, shared packages, complex browser UI, or code that benefits from typed contracts.
  • Follow the target project's existing stack for changes inside an existing project.
  • Require justification before adding a framework, build tool, backend, database, package manager, or new language.
  • State how much technical discretion DEV has, and when DEV must report back before proceeding.

Required output

Use the structure in docs/skills/pm-playbook/tech-scope.md.

Forbidden actions

  • Do not make TypeScript the default just because CodeFlowMu is TypeScript.
  • Do not make Python the default just because it is a strong general-purpose AI-development language.
  • Do not add a framework or build system for a task that can be delivered cleanly as a static file or small script.
  • Do not hide deployment, runtime, or environment assumptions from DEV.
  • Do not override explicit ADMIN or target-project constraints.

Minimal example

Deliverable: standalone browser mini-game
Preferred stack: static HTML/CSS/JS
Reason: no persistence, no shared package, no production build requirement
DEV discretion: may keep it single-file; must report before adding TypeScript or a bundler

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.
