What it does

Python Architecture is an agent skill from microsoft/apm, published by the product's own GitHub organization. Activate when creating new modules, refactoring class hierarchies, introducing design patterns, or making changes spanning 3+ files in the APM CLI codebase.

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Monitoring and alerting, Design patterns and Refactoring. It works with Python. The repository describes itself as: Agent Package Manager. The licence is MIT.

When your agent uses it

  • Tasks that involve Monitoring and alerting
  • Tasks that involve Design patterns
  • Tasks that involve Refactoring

Example prompts

  • “/python-architecture”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 280b8a7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Python Architecture loads about 347 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 125 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~347

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Python Architecture Skill

Python architect persona

When to activate

  • Creating new Python modules or packages under src/apm_cli/
  • Refactoring class hierarchies or introducing base classes
  • Changes that touch 3+ files with shared logic patterns
  • Introducing new design patterns (Strategy, Observer, etc.)
  • Cross-cutting concerns (logging, auth, error handling)
  • Performance-sensitive paths (parallel downloads, large manifests)

Key rules

  • Follow existing patterns (BaseIntegrator, CommandLogger, AuthResolver) before inventing new ones
  • Prefer composition over deep inheritance
  • Push shared logic into base classes, not duplicated across siblings
  • One canonical owner per decision: route through the existing authority (target_catalog, AuthResolver/host_providers, runtime registry, CommandLogger, CompiledOutputWriter, deployment_ledger, install-outcome, neutral hook IR, BaseIntegrator); extend it, never fork it. Full rule: .apm/instructions/architecture.instructions.md
  • Lock every centralization with a dual guardrail: a regression test plus a static check in scripts/lint-architecture-boundaries.sh

Can I use Python Architecture in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add microsoft/apm --skill python-architecture -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/python-architecture, .gemini/skills/python-architecture, .github/skills/python-architecture and .opencode/skills/python-architecture in your project.

What does Python Architecture need to run?

SKILL.md names no scripts, command-line tools or credentials: Python Architecture is instructions for the agent only. Our summary lists: Python 3.

Does Python Architecture access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Python Architecture safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Python Architecture use?

Python Architecture is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Python Architecture use?

About 347 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
