description	File a Bugzilla bug directly via the BMO REST API with full power the prefilled enter_bug.cgi form can't do — create the bug AND upload one or more attachments (logs, patches, testcases, screenshots) AND set bug-/attachment-level flags (needinfo?, review?, sec-approval?, approval-mozilla-*?, tracking flags) in one confirmed operation. Also attaches files to, and sets flags on, existing bugs. Use when the user wants to actually submit a bug (not just open a draft form), attach files while filing, or set flags. For a simple file-it-myself-in-the-browser draft with no attachments, prefer the form-based `bug-filing` skill instead. Requires a Bugzilla API key.

Bug Filing (Pro) Skill

Files and edits Bugzilla bugs through the BMO REST API, so it can do what the form-based bug-filing skill cannot: submit the bug, attach multiple files, and set every flag — in a single confirmed run.

Dependencies and Bugzilla API-key setup live in README.md. Point the user there if bmo-file-bug --check-auth fails.

When to use this vs. the form-based bug-filing skill

• This skill (bug-filing-pro) — the user wants the bug actually filed, needs to attach files (logs, patches, reduced testcases, about:support, screenshots) and/or set flags, or wants to attach/flag an existing bug.
• Plain bug-filing — the user just wants a prefilled enter_bug.cgi form opened to review and submit by hand, with no attachments or flags.

The bug is created under the API-key owner's identity. Because of that, every write is gated: always dry-run + preview, then get explicit confirmation, then file. Never skip the confirmation step.

Security

The Bugzilla API key grants full write access under the user's identity. It is resolved inside shared/bmo_client.py and never enters the conversation. Never read, echo, or pass the key. To verify it is wired up (prints presence and source path, never the value):

python3 .claude/skills/bug-filing-pro/bmo-file-bug --check-auth

Workflow (filing a new bug)

Step 0 — Verify the API key (do this first)

Run python3 .claude/skills/bug-filing-pro/bmo-file-bug --check-auth. If it reports a key, continue normally. If no key is found, don't dead-end — use AskUserQuestion to offer two paths:

• Set up an API key — point the user to README.md for the one-time setup, then re-check. This unlocks attachments + flags via the API.
• File it in the browser myself (no key) — proceed through Steps 1–3 to draft the body, then in Step 6 run create … --browser-file (no --dry-run). That opens the prefilled enter_bug.cgi form for the user to submit under their own account. The form cannot carry attachments or flags, so tell the user those must be added manually afterward (or set a key to automate). Skip the attachment/flag gathering in Step 4 accordingly.

Catching this up front means the user never reaches a final-step "no key" error.

Step 1 — Determine product and component

If the change touches a file in the tree, run ./mach file-info bugzilla-component <file> on a representative file. Output is Product :: Component; split on ::. If it returns UNKNOWN, pick the closest sensible component. Otherwise ask the user.

Step 2 — Choose the bug type

• defect — shipping software misbehaving (regression, crash, error).
• enhancement — a new feature, or changing how a feature behaves.
• task — config/refactor/tooling/tests/docs with no user-facing change.

Step 3 — Draft the summary and description

• Keep the summary short and specific.
• Wrap code identifiers (functions, vars, files, prefs, flags) in backticks.
• For a test-failure bug, link the test dashboard: https://tests.firefox.dev/test.html?test=<path>.
• Write the description to a file and pass it with --description-file (so real newlines and markdown survive shell quoting).

Step 4 — Gather attachments and flags

(Skip this in browser-file mode — enter_bug.cgi can't carry attachments or flags, and they require an API key.)

• Simple files: one --attach <path> each (type and is_patch auto-detected).
• For per-attachment summaries/flags/privacy, write an --attachments-json file (schema below).
• Bug-level flags: --flag 'name:status[:requestee]' (e.g. --flag 'needinfo:?:[e-mail]').
• Tracking flags are fields, not flags: --field cf_status_firefox142=affected.

Step 5 — Dry-run and preview (REQUIRED for API filing)

Run with --dry-run. Default --preview html opens a local page rendering the full request (fields, flags, attachments table); use --preview form to show the body in BMO's native enter-bug form (body only — do not submit it).

Two browser modes, don't confuse them: --preview form is review-only — do not submit it (the API does the real filing on confirmation, so submitting would create a duplicate). --browser-file (Step 0 no-key path) is the opposite — there you do submit the form yourself and the API is never used.

(In browser-file mode there's nothing to dry-run; go straight to Step 6.)

python3 .claude/skills/bug-filing-pro/bmo-file-bug create \
    --product Core --component "Audio/Video: Playback" \
    --summary "<summary>" --description-file /tmp/desc.md \
    --type defect --severity S2 --priority P2 \
    --flag 'needinfo:?:[e-mail]' \
    --attach /tmp/crash.log --attach /tmp/fix.patch \
    --dry-run --preview html

Show the user the printed payload.

Step 6 — Confirm, then file

Confirm with AskUserQuestion, "Looks good, file the bug" as the first (recommended) option. Only on approval, re-run the exact same command without --dry-run (and without --preview). The script creates the bug, uploads each attachment, sets flags, then prints the bug URL.

If an attachment fails after the bug is created, the script reports which succeeded and prints the precise bmo-file-bug attach <id> … retry command — relay it; the bug itself is already filed.

No-key path (from Step 0): run the same create command with --browser-file (and no --dry-run). It opens the prefilled form in the browser for the user to submit themselves and prints which attachments/flags it couldn't include. Nothing is filed by the script — tell the user to click Submit, then add those attachments/flags manually on the new bug.

Other operations

attach and flags always require an API key (no browser fallback — enter_bug.cgi can't upload files or set flags).

Attach to an existing bug:

python3 .claude/skills/bug-filing-pro/bmo-file-bug attach <bug-id> \
    --attach /tmp/repro.html --dry-run --preview html

Set flags / fields on a bug or attachment:

python3 .claude/skills/bug-filing-pro/bmo-file-bug flags <bug-id> \
    --flag 'needinfo:?:[e-mail]' --field cf_status_firefox142=fixed \
    --attachment <attId> --attachment-flag 'review:+' --dry-run

List a bug's attachments and their flags:

python3 .claude/skills/bug-filing-pro/bmo-file-bug list <bug-id>

Reference

Flag syntax

name:status[:requestee] — status is one of ? + - X. Colon-separated so hyphenated names (sec-approval, approval-mozilla-beta) are unambiguous. Examples: review:?:[e-mail], sec-approval:?, approval-mozilla-beta:+.

--attachments-json schema (array of objects)

[
  {
    "path": "/tmp/fix.patch",
    "summary": "Proposed fix",
    "file_name": "fix.patch",
    "content_type": "text/plain",
    "is_patch": true,
    "is_private": false,
    "comment": "optional comment posted with the attachment",
    "flags": [{"name": "review", "status": "?", "requestee": "[e-mail]"}]
  }
]

Only path is required; everything else is auto-detected or optional.

Notes

• A new bug is created under the API-key owner's account — confirm before filing.
• BMO has no atomic "create + attach" call: the script creates the bug, then uploads attachments one per request, all within the single confirmed run.
