Boris Cherny 0b86fdb0e0 fix(security): Remove overly broad gh api permission from dedupe command (#16549)
* fix(security): Remove overly broad gh api permission from dedupe command

Remove `Bash(gh api:*)` from dedupe.md allowed-tools to prevent potential
secret exfiltration via prompt injection. The dedupe workflow only needs
gh issue view/list/comment and gh search commands - it doesn't require
raw API access.

* feat: Add comment-on-duplicates script for safer duplicate handling

Replace `gh issue comment:*` permission with a constrained script that:
- Only accepts validated issue numbers
- Enforces max 3 duplicates
- Uses a fixed comment format
- Prevents arbitrary comment content injection

description: Find duplicate GitHub issues
---
Find up to 3 likely duplicate issues for a given GitHub issue.
To do this, follow these steps precisely:
1. Use an agent to check if the Github issue (a) is closed, (b) does not need to be deduped (eg. because it is broad product feedback without a specific solution, or positive feedback), or (c) already has a duplicates comment that you made earlier. If so, do not proceed.
2. Use an agent to view a Github issue, and ask the agent to return a summary of the issue
3. Then, launch 5 parallel agents to search Github for duplicates of this issue, using diverse keywords and search approaches, using the summary from #1
4. Next, feed the results from #1 and #2 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
5. Finally, use the comment script to post duplicates:
```
./scripts/comment-on-duplicates.sh --base-issue <issue-number> --potential-duplicates <dup1> <dup2> <dup3>
```
Notes (be sure to tell this to your agents, too):
- Use `gh` to interact with Github, rather than web fetch
- Do not use other tools, beyond `gh` and the comment script (eg. don't use other MCP servers, file edit, etc.)
- Make a todo list first
