fix: clear stale claude-prompts dir before each write by kyungilpark · Pull Request #1288 · anthropics/claude-code-action (original) (raw)

Previously, prompt files at ${RUNNER_TEMP}/claude-prompts/ from a prior invocation could persist on non-ephemeral self-hosted runners (where the documented RUNNER_TEMP cleanup contract is not reliably honored). In particular, claude-user-request.txt is only written by create-prompt when a user request exists; an agent-mode invocation does not overwrite it, so a stale value left by an earlier mention-mode job in another repo would leak into a later agent-mode job's effective context on the same runner agent.

Fix: rm -rf the directory before mkdir in both write sites (src/create-prompt/index.ts, src/modes/agent/index.ts). Idempotent, safe on hosted runners (where the dir is already empty), and self-heals on self-hosted runners.
