How to update

Step 1: Identify what changed

• •Contract surface changed? → Update interface-private-architecture.instructions.md
• •Phase advanced? → Update interface-private-roadmap.instructions.md
• •Build process changed? → Update interface-build-and-test.instructions.md
• •Conventions changed? → Update interface-coding-conventions.instructions.md
• •Repo structure changed? → Update interface-project-structure.instructions.md
• •Strategy shifted? → Update interface-private-strategy.instructions.md
• •Review priorities changed? → Update interface-code-review.instructions.md

Step 2: Read the current file and update it

Use read_file to load, then edit with current state.

Step 3: Keep instructions concise

• •State facts, not procedures (procedures go in skills)
• •Use tables over prose
• •Target under 50 lines per file

Step 4: Cross-repo consistency

If the change affects contracts, update corresponding files in:

• •Phoenix-Agentic-Engine-Backend/.github/instructions/
• •Phoenix-Agentic-Engine/.github/instructions/

Step 5: Verify no secrets leaked (PUBLIC repo)

This is a public repo. Instruction files must NOT contain:

• •System prompts or prompt templates
• •API keys or credentials
• •Orchestration implementation details

Instruction file format

Manual-only (most files)

# Title

Content here. Keep it concise.

No frontmatter = manual-only. Agent loads these via the load-interface-instructions skill.

With excludeAgent guard (code-review only)

---
excludeAgent: "coding-agent"
---

# Title

Content here.

The excludeAgent guard prevents the autonomous coding agent from using this file even if manually attached.
