Using Arch Compiler

Using Architecture Compiler

Read This First

Before doing anything else:

1. Read AGENTS.md.
2. Treat tools/, schemas/, config/, and patterns/ as read-only unless the human explicitly asked for compiler-maintenance work in this repo.
3. Decide whether the task is about architecture selection or architecture implementation.

Routing Rule

Use skills/compiling-architecture/SKILL.md when:

• the user wants to turn requirements into architecture decisions
• the user wants to write or refine a spec
• the user wants to compile, recompile, inspect pattern selection, or finalise an architecture
• the user has an existing prototype or codebase and needs to compile, validate, or re-approve the architecture it should converge to
• docs/architecture/ does not exist yet
• docs/architecture/architecture.yaml is missing approval
• implementation planning or coding exposes unresolved provider/runtime/auth/retention/message-path decisions
• any later decision would change constraints.*, constraints.saas-providers, top-level patterns.*, or accepted risk posture
• the user wants existing prototype choices to replace approved providers, boundaries, or selected patterns

Use skills/implementing-architecture/SKILL.md when:

• docs/architecture/architecture.yaml exists
• it is approved
• the task is to write code that follows that architecture
• the task is to refactor an existing prototype or codebase so it conforms to the approved architecture
• provider/runtime bindings are already concrete enough that coding will not silently replace the approved contract

Hard Stops

• If the full Architecture Compiler repo is not installed in a stable local path, stop and install it before routing further. Installing only copied skill files is not enough; the workflows depend on tools/, schemas/, config/, and patterns/.
• If no application repo exists yet, do not write app architecture artifacts into the compiler repo.
• If an implementation task lacks approved architecture, stop and switch to the compiling skill.
• If planning starts under the implementing skill and reveals unresolved architecture-binding choices, stop and route back to the compiling skill before more planning or coding.
• If a previously approved architecture is recompiled or materially changed, treat the old approval as invalid until the human re-approves the new output.
• If the user is asking to change compiler behavior or the pattern registry itself, this is compiler-maintenance work, not normal skill usage.

Output

After choosing, explicitly say which of the two skills you are using and why.
