 # CompText V7 Agent Instructions
 
+## Repo-local skill docs
+- Before starting work, read the relevant docs under `docs/codex_skills/`.
+- Use `docs/codex_skills/mcp_context_layer.md` for MCP context layer, CLI, prompt rendering, validation, and adapter work.
+- Use `docs/codex_skills/artifact_validation.md` for deterministic artifacts and regeneration checks.
+- Use `docs/codex_skills/git_pr_workflow.md` for branch sync, commits, pushes, and PR preparation.
+- Use `docs/codex_skills/docs_positioning.md` for README/docs positioning and scope boundaries.
+
+## Default safety rules
+- Repository state is the source of truth.
+- Inspect before editing.
+- Make the smallest safe patch.
+- Keep behavior deterministic and fixture-bound.
+- Maintain local sanitization and privacy boundaries (GDPR/DSGVO Art. 25) at all times.
+- Do not introduce semantic scoring, embeddings, vector DBs, external APIs, autonomous orchestration, or runtime tool execution unless explicitly scoped.
+- Prefer focused validation over broad checks unless the task requires broader validation.
+- Do not commit, push, create PRs, or merge unless explicitly requested.

 ## Project focus
 - CompText V7 is the deterministic replay-integrity layer for compressed operational agent traces.
 - Current focus: core foundation, deterministic replay artifacts, CI artifacts, docs, and conservative positioning.
