feat(cli): deny agentflare work when invoked by an AI agent - #484
Merged
getappz merged 3 commits intoAug 14, 2026
Conversation
agentflare work is meant for a human's own terminal or the daemon's in-process WorkItemExecutor -- not an AI agent shelling out to it, which bypasses the claim/queue bookkeeping the dashboard and agent_jobs table rely on and risks racing the daemon's own dispatch. WorkArgs::run now checks the same AI-agent marker env vars bashenv.rs's shim dispatcher already uses (CLAUDECODE, CURSOR_AGENT, CODEX_CLI_SESSION, GEMINI_SESSION, CODEBUDDY, LEAN_CTX_AGENT) before calling execute_work, and denies with a message naming why and what to do instead. Left as a strict, unconditional deny per scope -- a comment at the guard site flags the known tension with human-authorized-but-agent-executed recovery runs for a future override decision.

…nv-var list Item #113's original guard reimplemented bashenv.rs's marker env-var list. agent_detector::agent_name() is already the established primitive for this (claims.rs::owner_id, mcp_server.rs::identity, review.rs::submitter_name, cli/hook.rs::resolve_agent) and is strictly more robust -- it also walks the parent process tree, so it isn't defeated by an agent whose wrapper doesn't forward its marker env var through to a subprocess.

WorkArgs::runat the guard boundary.This test only calls
agent_detector::agent_name(). It does not prove thatWorkArgs::runperforms the check, emits the error, exits with status 1, or skipsexecute_work(). A future edit could remove or move the guard while this test still passes. Extract the decision into a testable helper, or add a child-process CLI test that asserts the exit status, stderr, and absence of work execution.🤖 Prompt for AI Agents

Summary
Implemented the guard exactly as scoped in item #113:
src/cli/work.rs: addedai_agent_env_marker(), checking the same marker env varsbashenv.rs's shim dispatcher uses (CLAUDECODE,CURSOR_AGENT,CODEX_CLI_SESSION,GEMINI_SESSION,CODEBUDDY,LEAN_CTX_AGENT).WorkArgs::runcalls it first, beforeexecute_work()—execute_workandWorkItemExecutor(the daemon's in-process dispatch path) are untouched, as required.ai_agent_env_marker_detects_claudecode_and_clears) — combined into one test rather than two, since env vars are process-global andcargo testparallelizes by default; two separate set/clear tests would race.bashenv.rs'sOPENCODE_*gap — flagging it here rather than silently expanding scope, per the item's own "or file separately" guidance.Verified:
cargo test --bin agentflare cli::work::— 45/45 pass. Manually ranCLAUDECODE=1 ./target/debug/agentflare work fake-id-123→ denied with the message, exit 1, before any claim attempt; without the marker vars → proceeds normally into real claim logic (fails only because the fake ID doesn't exist).One incidental fix needed to get builds running at all:
~/.cache/sccache(this worktree's configured sccache dir) is read-only in this environment, which broke everycargo build. Worked around it locally with a temporarySCCACHE_DIRoverride for verification only — no repo files changed for that, and I cleaned up the temp cache dir afterward.Summary by CodeRabbit
