Agents read multiple instruction surfaces in a single repo: repository-wide files such as AGENTS.md, CLAUDE.md, or .github/copilot-instructions.md, path-scoped .github/instructions/*.instructions.md, and tool-specific layers such as AGENTS.override.md where tools support overrides. Effective behavior is the merge of those layers—not whichever file was edited last in Git.
DirectiveOps models each discovered file with a precedence score derived from file type and path (for example, scoped instructions under .github/instructions/ rank above repo-wide defaults). The instruction viewer and constitution graph show which layers contribute directives so operators can answer "what is the agent effectively following here?"
Vendor tools differ in merge rules; DirectiveOps does not execute agents. Treat the dashboard as a reviewable mapof repo-resident directives, then validate critical behavior against each vendor's documentation for Codex, Copilot, Claude Code, or Gemini CLI.
