 This installs any missing skills, creates an agent API key, and prints shell exports to run as that agent.
 
+## Instructions Resolution
+
+If `instructionsFilePath` is configured, Paperclip reads that file and prepends it to the stdin prompt sent to `codex exec` on every run.
+
+This is separate from any workspace-level instruction discovery that Codex itself performs in the run `cwd`. Paperclip does not disable Codex-native repo instruction files, so a repo-local `AGENTS.md` may still be loaded by Codex in addition to the Paperclip-managed agent instructions.

 ## Environment Test

 Notes:
 - Prompts are piped via stdin (Codex receives "-" prompt argument).
+- If instructionsFilePath is configured, Paperclip prepends that file's contents to the stdin prompt on every run.
+- Codex exec automatically applies repo-scoped AGENTS.md instructions from the active workspace. Paperclip cannot suppress that discovery in exec mode, so repo AGENTS.md files may still apply even when you only configured an explicit instructionsFilePath.
 - Paperclip injects desired local skills into the active workspace's ".agents/skills" directory at execution time so Codex can discover "$paperclip" and related skills without coupling them to the user's login home.
 - Unless explicitly overridden in adapter config, Paperclip runs Codex with a per-company managed CODEX_HOME under the active Paperclip instance and seeds auth/config from the shared Codex home (the CODEX_HOME env var, when set, or ~/.codex).
 - Some model/tool combinations reject certain effort levels (for example minimal with web search enabled).
