What it does

Software Patterns is an agent skill from bobmatnyc/claude-mpm. Decision framework for architectural patterns including DI, SOA, Repository, Domain Events, Circuit Breaker, and Anti-Corruption Layer. Use when designing systems, choosing patterns, or reviewing architecture.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `.etag_cache.json`, `metadata.json` and `references/.etag_cache.json`).

The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

  • Designing systems
  • Choosing patterns
  • Reviewing architecture

Example prompts

  • “/software-patterns”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. First: Establish DI container/pattern
  2. Second: Define service boundaries (SOA)
  3. Third: Add Repository for data access
  4. Then: Layer situational patterns as problems emerge

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. 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

Software Patterns loads about 1.8k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 636 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~18k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 636 words (~1,776 tokens).

“Architectural patterns solve specific structural problems. This skill provides a decision framework for when to apply each pattern, not a catalog to memorize.”

Decision framework for architectural patterns including DI, SOA, Repository, Domain Events, Circuit Breaker, and Anti-Corruption Layer.

When should I use Software Patterns?

Software Patterns fits situations like: designing systems; choosing patterns; reviewing architecture.

How do I install Software Patterns in Claude Code?

Run `npx skills add bobmatnyc/claude-mpm --skill software-patterns -a claude-code`. Or copy the skill folder (plugin/skills/universal-architecture-software-patterns in bobmatnyc/claude-mpm) into .claude/skills/software-patterns in your project. Claude Code loads it when a task matches its description.

How do I install Software Patterns in Codex?

Run `npx skills add bobmatnyc/claude-mpm --skill software-patterns -a codex`. Or copy the skill folder (plugin/skills/universal-architecture-software-patterns in bobmatnyc/claude-mpm) into .agents/skills/software-patterns in your project. Codex loads it when a task matches its description.

Can I use Software Patterns 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 bobmatnyc/claude-mpm --skill software-patterns -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/software-patterns, .gemini/skills/software-patterns, .github/skills/software-patterns and .opencode/skills/software-patterns in your project.

What does Software Patterns need to run?

SKILL.md names no scripts, command-line tools or credentials: Software Patterns is instructions for the agent only.

Does Software Patterns 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 Software Patterns 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 Software Patterns use?

Software Patterns has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Software Patterns use?

About 1.8k tokens (SKILL.md is roughly 7.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 17k tokens, read only when the agent opens those files.

What are the alternatives to Software Patterns?

Skills that share tags, products or a category with Software Patterns: Architecture Patterns (wshobson/agents, 40k stars), Android Clean Architecture (affaan-m/ECC, 275k stars), Architecture Patterns (davila7/claude-code-templates, 32k stars) and Architecture Docs Writer (prisma/orm, 48k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
