Agent Improvement Proposal

Pattern Detected

Type: config_adjustment (permission fix)
Affected Agent: ca-bug-hunter
Evidence: Bug hunter pool completely blocked — all workers failing on git clone

Detailed Evidence

The bug hunter pool supervisor reported at 2026-04-06T06:18:11Z on session state issue #3775:

[CRITICAL] Bug hunter supervisor hunter-pool-1 is blocked.

All dispatched workers are failing because they cannot clone the repository due to restrictions in the execution environment. The git clone command is not permitted.

Error: The user has specified a rule which prevents you from using this specific tool call. on git clone.

Blocked workers: alembic, asv, benchmarks, docs, examples, features, hooks, k8s, src

Root Cause Analysis:

The ca-bug-hunter.md agent definition has a mismatch between its instructions and its permissions:

  • Instructions (Worker Mode, line 228-242): "CRITICAL: You MUST work in your own isolated clone. NEVER operate in /app." followed by git clone https://<FORGEJO_PAT>@<FORGEJO_HOST>/<owner>/<repo>.git "$CLONE_DIR"

  • Permissions (lines 19-36): The bash permissions only include read-only git commands:

    "git log*": allow
    "git status*": allow
    "git diff*": allow
    "git show*": allow
    "git branch*": allow
    

    Missing: "git clone*": allow, "git config*": allow, and directory operations ("cd *": allow, "mkdir *": allow, "rm -rf *": allow)

The agent needs git clone to create its isolated working copy, git config to set identity, and directory operations for clone management.

Proposed Change

Add the missing bash permissions to ca-bug-hunter.md's frontmatter:

permission:
  bash:
    # ... existing permissions ...
    # Git clone for worker mode isolation:
    "git clone*": allow
    "git config*": allow
    # Directory operations for clone management:
    "cd *": allow
    "mkdir *": allow
    "rm -rf *": allow

This aligns the permissions with the agent's documented Worker Mode Clone Isolation Protocol.

Expected Impact

  • Bug hunter pool unblocked: All 8+ workers will be able to clone and scan modules
  • Proactive bug detection restored: The system will resume finding bugs before they manifest
  • Zero risk to other agents: This only affects ca-bug-hunter's own permissions

Risk Assessment

  • Very low risk: This is a permission fix that aligns permissions with documented behavior
  • No behavioral change: The agent already tries to clone — this just allows it to succeed
  • Read-only safety preserved: The agent still has edit: deny, so it cannot modify files in the repo — it can only read and file issues

This is a proposal from the agent evolver. A human must approve this issue before the change will be implemented. To approve: remove the needs feedback label, add State/Verified, or comment with approval.

## Agent Improvement Proposal ### Pattern Detected **Type**: config_adjustment (permission fix) **Affected Agent**: `ca-bug-hunter` **Evidence**: Bug hunter pool completely blocked — all workers failing on git clone ### Detailed Evidence The bug hunter pool supervisor reported at 2026-04-06T06:18:11Z on session state issue #3775: > **[CRITICAL] Bug hunter supervisor `hunter-pool-1` is blocked.** > > All dispatched workers are failing because they cannot clone the repository due to restrictions in the execution environment.

MoSCoW classification: MoSCoW/Should Have

Rationale: This proposal fixes a real operational gap — the bug-hunter pool is completely blocked because the agent definition's permissions don't include git clone, which the agent's own documented Worker Mode Clone Isolation Protocol requires. This is a clear permission/config mismatch.

Why Should Have (not Must Have):

  • The bug-hunter is a quality monitoring tool, not core product functionality
  • The system continues to function without proactive bug detection
  • The fix is low-risk (permission alignment, no behavioral change)
  • However, restoring proactive bug detection is important for overall system quality

Why Should Have (not Could Have):

  • The bug-hunter pool is completely blocked, not just degraded
  • Proactive bug detection is a key quality gate for a system with 878+ open bugs
  • The fix is straightforward and well-documented

This should be implemented in the next available cycle after higher-priority work.
