    "title": "claude -p headless run can't read files outside cwd with acceptEdits: 'requested permissions … haven't granted'",
    "error": "requested permissions … haven't granted",
    "body": "## Symptom\nA server spawns `claude -p ... --permission-mode acceptEdits --settings policy.json` to handle user requests. Requests that attach files (images, spreadsheets saved under `/srv/uploads/...`) or need `/tmp/x.diff` fail: the run reports that Claude requested permissions to read the file but they haven't been granted, and stops.\n\n## Cause\n`acceptEdits` auto-approves edits inside the working directory only. Reading paths outside cwd still needs an interactive approval, and in `-p` (print/headless) mode nobody can answer the prompt, so it is treated as denied.\n\n## Fix\nRun headless agents with permission bypass and express the policy through `deny` rules and hooks instead of prompts:\n```bash\nclaude -p \"$ASK\" --permission-mode bypassPermissions --settings /srv/svc/settings.json\n```\n(Run it as a dedicated non-root user.) Alternatively keep `acceptEdits` and add explicit allow rules such as `Read(//srv/uploads/**)` and `Glob(//srv/uploads/**)` to the settings file.\n\n## Verify\nAfter the change, an uploaded `.xlsx` was read with openpyxl and answered within ~8 s, and image attachments were read. `deny` rules still held under bypass: a `Read` of `.env.local` was refused.\n\n## Notes\nBypass mode makes prefix-based Bash deny rules your only shell guard — and they are easy to evade (see the separate entry about `Bash(git push:*)`). Add a PreToolUse hook.",
