| " --append-system-prompt "You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements. | |
| General guidelines. | |
| - When you execute commands, always save their logs to files for easier reading if the output becomes large. | |
| - When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file. | |
| - When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command. | |
| - When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps: | |
| Step 1: List recent runs with timestamps using: gh run list --repo Jhon-Crow/godot-topdown-MVP --branch issue-93-43a6ffeaa53a --limit 5 --json databaseId,conclusion,createdAt,headSha | |
| Step 2: Verify runs are after the latest commit by checking timestamps and SHA | |
| Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo Jhon-Crow/godot-topdown-MVP --log > ci-logs/{workflow}-{run-id}.log | |
| Step 4: Read each downloaded log file using Read tool to understand the actual failures | |
| Step 5: Report findings with specific errors and line numbers from logs | |
| This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR. | |
| Note: If user says \"failing\" but tools show \"passing\", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy. | |
| - When a code or log file has more than 1500 lines, read it in chunks of 1500 lines. | |
| - When facing a complex problem, do as much tracing as possible and turn on all verbose modes. | |
| - When you create debug, test, or example/experiment scripts for fixing, always keep them in an examples and/or experiments folders so you can reuse them later. | |
| - When testing your assumptions, use the experiment scripts, and add it to experiments folder. | |
| - When your experiments can show real world use case of the software, add it to examples folder. | |
| - When you face something extremely hard, use divide and conquer — it always helps. | |
| Initial research. | |
| - When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality. | |
| - When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs. | |
| - When you read issue, read all details and comments thoroughly. | |
| - When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, use WebFetch tool (or fetch tool) to download the image first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's HTML 404 pages saved as .png) can cause \"Could not process image\" errors and may crash the AI solver process. If the file command shows \"HTML\" or \"text\", the download failed and you should retry or skip the image. | |
| - When you need issue details, use gh issue view https://github.com/Jhon-Crow/godot-topdown-MVP/issues/93. | |
| - When you need related code, use gh search code --owner Jhon-Crow [keywords]. | |
| - When you need repo context, read files in your working directory. | |
| - When you study related work, study the most recent related pull requests. | |
| - When issue is not defined enough, write a comment to ask clarifying questions. | |
| - When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication. | |
| - When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed. | |
| - When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default. | |
| - When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints: | |
| 1. PR review comments (inline code comments): gh api repos/Jhon-Crow/godot-topdown-MVP/pulls/107/comments --paginate | |
| 2. PR conversation comments (general discussion): gh api repos/Jhon-Crow/godot-topdown-MVP/issues/107/comments --paginate | |
| 3. PR reviews (approve/request changes): gh api repos/Jhon-Crow/godot-topdown-MVP/pulls/107/reviews --paginate | |
| IMPORTANT: The command \"gh pr view --json comments\" ONLY returns conversation comments and misses review comments! | |
| - When you need latest comments on issue, use gh api repos/Jhon-Crow/godot-topdown-MVP/issues/93/comments --paginate. | |
| Solution development and testing. | |
| - When issue is solvable, implement code with tests. | |
| - When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch. | |
| - When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request. | |
| - When you test: | |
| start from testing of small functions using separate scripts; | |

| [2026-01-18T03:55:49.277Z] [INFO] You are an AI issue solver. You prefer to find the root cause of each and every issue. When you talk, you prefer to speak with facts which you have double-checked yourself or cite sources that provide evidence, like quote actual code or give references to documents or pages found on the internet. You are polite and patient, and prefer to assume good intent, trying your best to be helpful. If you are unsure or have assumptions, you prefer to test them yourself or ask questions to clarify requirements. | |
| General guidelines. | |
| - When you execute commands, always save their logs to files for easier reading if the output becomes large. | |
| - When running commands, do not set a timeout yourself — let them run as long as needed (default timeout - 2 minutes is more than enough), and once they finish, review the logs in the file. | |
| - When running sudo commands (especially package installations like apt-get, yum, npm install, etc.), always run them in the background to avoid timeout issues and permission errors when the process needs to be killed. Use the run_in_background parameter or append & to the command. | |
| - When CI is failing or user reports failures, consider adding a detailed investigation protocol to your todo list with these steps: | |
| Step 1: List recent runs with timestamps using: gh run list --repo Jhon-Crow/godot-topdown-MVP --branch issue-93-43a6ffeaa53a --limit 5 --json databaseId,conclusion,createdAt,headSha | |
| Step 2: Verify runs are after the latest commit by checking timestamps and SHA | |
| Step 3: For each non-passing run, download logs to preserve them: gh run view {run-id} --repo Jhon-Crow/godot-topdown-MVP --log > ci-logs/{workflow}-{run-id}.log | |
| Step 4: Read each downloaded log file using Read tool to understand the actual failures | |
| Step 5: Report findings with specific errors and line numbers from logs | |
| This detailed investigation is especially helpful when user mentions CI failures, asks to investigate logs, you see non-passing status, or when finalizing a PR. | |
| Note: If user says "failing" but tools show "passing", this might indicate stale data - consider downloading fresh logs and checking timestamps to resolve the discrepancy. | |
| - When a code or log file has more than 1500 lines, read it in chunks of 1500 lines. | |
| - When facing a complex problem, do as much tracing as possible and turn on all verbose modes. | |
| - When you create debug, test, or example/experiment scripts for fixing, always keep them in an examples and/or experiments folders so you can reuse them later. | |
| - When testing your assumptions, use the experiment scripts, and add it to experiments folder. | |
| - When your experiments can show real world use case of the software, add it to examples folder. | |
| - When you face something extremely hard, use divide and conquer — it always helps. | |
| Initial research. | |
| - When you start, make sure you create detailed plan for yourself and follow your todo list step by step, make sure that as many points from these guidelines are added to your todo list to keep track of everything that can help you solve the issue with highest possible quality. | |
| - When user mentions CI failures or asks to investigate logs, consider adding these todos to track the investigation: (1) List recent CI runs with timestamps, (2) Download logs from failed runs to ci-logs/ directory, (3) Analyze error messages and identify root cause, (4) Implement fix, (5) Verify fix resolves the specific errors found in logs. | |
| - When you read issue, read all details and comments thoroughly. | |
| - When you see screenshots or images in issue descriptions, pull request descriptions, comments, or discussions, use WebFetch tool (or fetch tool) to download the image first, then use Read tool to view and analyze it. IMPORTANT: Before reading downloaded images with the Read tool, verify the file is a valid image (not HTML). Use a CLI tool like 'file' command to check the actual file format. Reading corrupted or non-image files (like GitHub's HTML 404 pages saved as .png) can cause "Could not process image" errors and may crash the AI solver process. If the file command shows "HTML" or "text", the download failed and you should retry or skip the image. | |
| - When you need issue details, use gh issue view https://github.com/Jhon-Crow/godot-topdown-MVP/issues/93. | |
| - When you need related code, use gh search code --owner Jhon-Crow [keywords]. | |
| - When you need repo context, read files in your working directory. | |
| - When you study related work, study the most recent related pull requests. | |
| - When issue is not defined enough, write a comment to ask clarifying questions. | |
| - When accessing GitHub Gists (especially private ones), use gh gist view command instead of direct URL fetching to ensure proper authentication. | |
| - When you are fixing a bug, please make sure you first find the actual root cause, do as many experiments as needed. | |
| - When you are fixing a bug and code does not have enough tracing/logs, add them and make sure they stay in the code, but are switched off by default. | |
| - When you need comments on a pull request, note that GitHub has THREE different comment types with different API endpoints: | |
| 1. PR review comments (inline code comments): gh api repos/Jhon-Crow/godot-topdown-MVP/pulls/107/comments --paginate | |
| 2. PR conversation comments (general discussion): gh api repos/Jhon-Crow/godot-topdown-MVP/issues/107/comments --paginate | |
| 3. PR reviews (approve/request changes): gh api repos/Jhon-Crow/godot-topdown-MVP/pulls/107/reviews --paginate | |
| IMPORTANT: The command "gh pr view --json comments" ONLY returns conversation comments and misses review comments! | |
| - When you need latest comments on issue, use gh api repos/Jhon-Crow/godot-topdown-MVP/issues/93/comments --paginate. | |
| Solution development and testing. | |
| - When issue is solvable, implement code with tests. | |
| - When implementing features, search for similar existing implementations in the codebase and use them as examples instead of implementing everything from scratch. | |
| - When coding, each atomic step that can be useful by itself should be commited to the pull request's branch, meaning if work will be interrupted by any reason parts of solution will still be kept intact and safe in pull request. | |
| - When you test: | |
| start from testing of small functions using separate scripts; | |
| write unit tests with mocks for easy and quick start. | |
| - When you test integrations, use existing framework. | |
| - When you test solution draft, include automated checks in pr. | |
| - When issue is unclear, write comment on issue asking questions. | |
| - When you encounter any problems that you unable to solve yourself (any human feedback or help), write a comment to the pull request asking for help. | |

Stop too frequently when moving along a long piece of cover\n2. Get stuck at the last cover before the player (walking into walls or standing still)\n\n### Root Causes Identified\n\n1. **No obstacle differentiation**: Cover positions on the same obstacle as current cover were scored equally, causing repeated small movements along the same wall\n2. **No minimum progress requirement**: Covers just a few pixels closer were valid, causing excessive stopping\n3. **No approach fallback**: When at the last cover with no better option, enemies had no graceful way to approach the player\n4. **No path verification**: Cover positions could be unreachable if walls blocked the path\n\n### Solutions Implemented\n\n- **Same-obstacle penalty** (-4.0 score): Covers on the same obstacle receive a penalty, encouraging movement to different covers\n- **Minimum progress requirement** (10%): Covers must get enemy at least 10% closer to player to be considered\n- **Approach phase** (up to 3 seconds): When no better cover exists, enemies move directly toward player until they can hit or timeout\n- **Path verification**: Verify cover positions are reachable before selecting them\n\n### New Variables/Constants\n\n| Name | Type | Value | Description |\n|------|------|-------|-------------|\n| `_current_cover_obstacle` | Object | null | Tracks current cover's obstacle |\n| `_pursuit_approaching` | bool | false | Whether in approach phase |\n| `_pursuit_approach_timer` | float | 0.0 | Timer for approach phase |\n| `PURSUIT_APPROACH_MAX_TIME` | const | 3.0 | Max seconds in approach phase |\n| `PURSUIT_MIN_PROGRESS_FRACTION` | const | 0.10 | Min 10% progress required |\n| `PURSUIT_SAME_OBSTACLE_PENALTY` | const | 4.0 | Score penalty for same obstacle |\n\n### Debug Label\n\nAdded `(APPROACH Xs)` label when enemy is in approach phase during PURSUING state.\n\n## Test plan\n\n- [ ] Test long cover scenario:\n - Enemy should NOT stop multiple times along the same wall\n - Should skip to end of wall or find different cover\n \n- [ ] Test last cover scenario:\n - Enemy should enter APPROACH phase when no better cover exists\n - Should move toward player (not stand still or walk into walls)\n - Should transition to COMBAT when can hit player or after 3 seconds\n \n- [ ] Test path verification:\n - Enemy should NOT select cover positions blocked by walls\n \n- [ ] Verify existing behaviors still work:\n - Cover-to-cover pursuit still works normally\n - ASSAULT state coordination works\n - COMBAT state cycling works\n - RETREATING under fire works\n\n## Files Changed\n\n- `scripts/objects/enemy.gd`: Main fix implementation\n- `docs/case-studies/issue-93/`: Comprehensive case study with analysis\n- `tests/unit/test_pursuing_state.gd`: Unit tests for the fix\n\n## References\n\n- [Case Study: Issue #93](docs/case-studies/issue-93/README.md)\n- Related: Issue #88, PR #89 (original PURSUING state implementation)\n\n---\nFixes Jhon-Crow/godot-topdown-MVP#93\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)", | |

Stop too frequently when moving along a long piece of cover\n2. Get stuck at the last cover before the player (walking into walls or standing still)\n\n### Root Causes Identified\n\n1. **No obstacle differentiation**: Cover positions on the same obstacle as current cover were scored equally, causing repeated small movements along the same wall\n2. **No minimum progress requirement**: Covers just a few pixels closer were valid, causing excessive stopping\n3. **No approach fallback**: When at the last cover with no better option, enemies had no graceful way to approach the player\n4. **No path verification**: Cover positions could be unreachable if walls blocked the path\n\n### Solutions Implemented\n\n- **Same-obstacle penalty** (-4.0 score): Covers on the same obstacle receive a penalty, encouraging movement to different covers\n- **Minimum progress requirement** (10%): Covers must get enemy at least 10% closer to player to be considered\n- **Approach phase** (up to 3 seconds): When no better cover exists, enemies move directly toward player until they can hit or timeout\n- **Path verification**: Verify cover positions are reachable before selecting them\n\n### New Variables/Constants\n\n| Name | Type | Value | Description |\n|------|------|-------|-------------|\n| `_current_cover_obstacle` | Object | null | Tracks current cover's obstacle |\n| `_pursuit_approaching` | bool | false | Whether in approach phase |\n| `_pursuit_approach_timer` | float | 0.0 | Timer for approach phase |\n| `PURSUIT_APPROACH_MAX_TIME` | const | 3.0 | Max seconds in approach phase |\n| `PURSUIT_MIN_PROGRESS_FRACTION` | const | 0.10 | Min 10% progress required |\n| `PURSUIT_SAME_OBSTACLE_PENALTY` | const | 4.0 | Score penalty for same obstacle |\n\n### Debug Label\n\nAdded `(APPROACH Xs)` label when enemy is in approach phase during PURSUING state.\n\n## Test plan\n\n- [ ] Test long cover scenario:\n - Enemy should NOT stop multiple times along the same wall\n - Should skip to end of wall or find different cover\n \n- [ ] Test last cover scenario:\n - Enemy should enter APPROACH phase when no better cover exists\n - Should move toward player (not stand still or walk into walls)\n - Should transition to COMBAT when can hit player or after 3 seconds\n \n- [ ] Test path verification:\n - Enemy should NOT select cover positions blocked by walls\n \n- [ ] Verify existing behaviors still work:\n - Cover-to-cover pursuit still works normally\n - ASSAULT state coordination works\n - COMBAT state cycling works\n - RETREATING under fire works\n\n## Files Changed\n\n- `scripts/objects/enemy.gd`: Main fix implementation\n- `docs/case-studies/issue-93/`: Comprehensive case study with analysis\n- `tests/unit/test_pursuing_state.gd`: Unit tests for the fix\n\n## References\n\n- [Case Study: Issue #93](docs/case-studies/issue-93/README.md)\n- Related: Issue #88, PR #89 (original PURSUING state implementation)\n\n---\nFixes Jhon-Crow/godot-topdown-MVP#93\n\n🤖 Generated with [Claude Code](https://claude.com/claude-code)", | |

Let me read the current enemy.gd implementation." | |

| "text": "Now I need to understand the issue better. Looking at lines 1571-1574, when no pursuit cover is found and the enemy can't see the player, it transitions to FLANKING. But from the FLANKING state (line 1194-1196), if `_can_see_player` is true, it immediately transitions back to COMBAT. And from the logs, this is causing the rapid PURSUING -> FLANKING -> COMBAT -> PURSUING cycling.\n\nThe core problem is that:\n1. In FLANKING, if `_can_see_player` is true, it immediately transitions to COMBAT (line 1194-1196)\n2. But in COMBAT, if conditions require pursuit, it goes back to PURSUING\n3. And in PURSUING, if no cover found and can't see player, it tries FLANKING again\n\nThis creates a rapid state cycling that doesn't actually move the enemy. Let me check the COMBAT state to understand when it transitions to PURSUING:" | |

In `_calculate_flank_position()` (lines 2572-2584), the flank target is calculated with a random side (`randf() > 0.5`) but it doesn't take into account whether the flank position is on the same side as the obstacle blocking the enemy.\n\nLet me also check what's being logged when the FLANKING state transitions. The key insight from the logs is:\n- Enemy7 shows `PURSUING -> FLANKING -> COMBAT -> PURSUING` cycling every 2 seconds\n- This suggests the enemy enters FLANKING, immediately sees the player, goes to COMBAT, then loses sight and goes back to PURSUING\n\nThe issue is that in FLANKING state, if `_can_see_player` is true, the enemy immediately goes to COMBAT (line 1194-1196) WITHOUT actually moving to the flank position first. This defeats the purpose of flanking.\n\nLet me trace through the specific issue:\n\n1. Enemy is at cover behind an obstacle\n2. Player is on the other side of the obstacle \n3. Enemy in PURSUING can see player (through gaps or around edges) but can't hit them\n4. Enemy transitions to FLANKING to try to get around\n5. BUT in FLANKING, `_can_see_player` check causes immediate transition to COMBAT\n6. In COMBAT, enemy still can't hit the player (wall in the way), so it either:\n - Goes to seeking_clear_shot phase\n - Or loses LOS and goes to PURSUING\n7. Cycle repeats\n\nThe fix should be: **FLANKING state should NOT immediately transition to COMBAT just because it can see the player.** The enemy should complete the flanking maneuver first.\n\nLet me check how `_can_see_player` is determined and whether there's a concept of \"can hit player\":" | |

The issue is:\n\n**Root Cause Analysis:**\n\n1. **In FLANKING** (line 1194-1196):\n ```gdscript\n if _can_see_player:\n _transition_to_combat()\n return\n ```\n This causes immediate exit from FLANKING if the enemy can see the player, even if the enemy can't actually hit them (wall in the way).\n\n2. **In COMBAT** (line 826-832):\n ```gdscript\n if not _can_see_player:\n _transition_to_pursuing()\n return\n ```\n And if the enemy can see but can't hit due to wall blocking (lines 897-918), it goes to seeking_clear_shot or flanking.\n\nThe problem is that the FLANKING state should use **`_can_hit_player_from_current_position()`** instead of just **`_can_see_player`** before transitioning to COMBAT. The enemy should complete the flank maneuver until they have a clear shot.\n\nLet me also check if there's a timing issue with the FLANKING state - the enemy might not be moving because it keeps recalculating the flank position and resetting:" | |

The enemy can see the player through a gap or around an edge\n2. But the enemy can't actually HIT the player because there's a wall in the way\n3. So the enemy should CONTINUE FLANKING until they have a clear shot\n\nThe fix is to change line 1194-1196 to check `_can_hit_player_from_current_position()` instead of just `_can_see_player`.\n\nAdditionally, I notice on line 1203, `_calculate_flank_position()` is called EVERY FRAME, which includes a random side selection. This means the flank target could switch sides randomly each frame, causing erratic behavior. The flank target should be set once when entering the FLANKING state and not recalculated every frame unless the player moves significantly.\n\nLet me check the FLANK_COVER_WAIT_DURATION constant:" | |

The main issues are:\n\n**Issue 1: FLANKING state transitions to COMBAT prematurely**\n- Line 1194-1196 checks `_can_see_player` but should check `_can_hit_player_from_current_position()`\n- The enemy should continue flanking until they have a clear shot, not just visibility\n\n**Issue 2: Random flank side selection every frame**\n- Line 2580 uses `randf() > 0.5` but this is called every frame in `_process_flanking_state()`\n- The flank side should be consistent for the duration of the flanking maneuver\n\n**Issue 3: Enemy doesn't persist in flanking direction**\n- When the enemy enters FLANKING, it should commit to a direction and stick with it\n\nLet me read more of the file to understand the state variables better:" | |
