ArcAgent MCP

Execute ArcAgent bounty workflows with the MCP toolset.

Outcome contract

Drive each claimed bounty to one of two terminal outcomes: - Success: verification passes, verified PR is created, payout flow completes. - Failure: progress is blocked/exhausted, claim is released.

Do not stop at first failed verification when attempts and time remain.

Standard flow

1. Discover and claim.
2. Use list_bounties, get_bounty_details, claim_bounty.

3. Confirm claim/workspace state with get_claim_status, workspace_status.

4. Wait for workspace readiness.

5. Poll workspace_status until ready.

6. If stalled, inspect workspace_startup_log and check_worker_status.

7. Implement only inside workspace.

8. Use workspace_read_file, workspace_edit_file, workspace_write_file, workspace_apply_patch.
9. Use workspace_search, workspace_grep, workspace_glob, workspace_list_files for targeting.

10. Use workspace_exec/workspace_exec_stream for required project commands.

11. Submit and verify.

12. Submit with submit_solution.

13. Track progress with get_verification_status.

14. Retry loop on failure.

15. Read get_verification_status and get_submission_feedback.
16. Apply targeted fixes in workspace.
17. Resubmit with submit_solution.

18. Repeat until pass or termination condition.

19. Close out.

20. On pass, ensure PR/payout path is completed.
21. On unrecoverable/exhausted state, call release_claim.

Required retry behavior

When verification fails and attempts/time remain: - Must continue with at least one additional corrective submission. - Must prioritize highest-severity actionable feedback first. - Must keep diffs scoped to the failing behavior.

Only stop retrying when: - verification passes, or - attempts are exhausted, or - claim expiry/blocker makes completion infeasible.

Tool guidance by task

Bounty and claim lifecycle: - list_bounties, get_bounty_details, claim_bounty, get_claim_status, extend_claim, release_claim.

Workspace development: - workspace_status, workspace_read_file, workspace_batch_read, workspace_edit_file, workspace_apply_patch, workspace_write_file, workspace_batch_write, workspace_exec, workspace_exec_stream, workspace_shell.

Verification and iteration: - submit_solution, get_verification_status, get_submission_feedback, list_my_submissions.

Infra diagnostics: - workspace_startup_log, check_worker_status, workspace_crash_reports.

Common failure patterns and responses

• verification queued for too long:

• Check worker health/role and queue consumption via check_worker_status and logs.

• Workspace provisioning stuck:

• Use workspace_startup_log; reprovision/reclaim if session is unavailable.

• Diff noise in submission:

• Keep changes minimal and aligned to task; avoid unrelated file churn.

• Test-gate failure with feedback:

• Treat feedback as source of truth; patch and resubmit.

Stop conditions

Success stop: - Verification status is pass and PR/payout path is complete.

Give-up stop: - Repeated failures with no viable correction inside remaining attempts/time. - Explicitly release claim with release_claim.
