Feature Flag Completion

> **Project context:** Values in angle brackets below (e.g. `<scheme>`, `<JIRA_KEY>`, `<flag-key-enum>`) are resolved at runtime — detect them from the project (`xcodebuild -list -json` for the scheme, `git`/`gh` for repo & owner, the branch name for the Jira key, a codebase search for flag/font files), or ask if they cannot be inferred. This plugin ships no per-project config.

Post-removal documentation for feature flag cleanup **$ARGUMENTS**.

This skill updates status.md, posts to Slack, and optionally updates Notion after a feature flag removal PR is merged.

**Note:** Run this skill AFTER updating `docs/feature-flags/status.md` with the removed flags.

Usage

/feature-flag-completed [pr_number]

• `pr_number` - Optional PR number (defaults to current branch's PR)

Steps

1. Gather Information

Get PR details using `gh pr view`:

• If PR number provided: `gh pr view <pr_number> --json number,title,url,body`
• If no PR number: `gh pr view --json number,title,url,body`

Extract the list of removed flags from the PR body (look for "Flags removed" table or list).

2. Read Current Status

Read `docs/feature-flags/status.md` and extract:

• Total removed count
• Total flags count
• Percentage
• In-Progress count
• Pending count

3. Post to Slack

Use `mcp__slack__conversations_add_message` to post to #flags-removal (ID: C0AST27EWTA):

:triangular_flag_on_post: Feature Flag Cleanup — Status Update
Progress: <removed> / <total> removed (<percentage>%)
In-Progress: <in_progress>
Pending: <pending>

Recently Removed:
- <flag_name_1> — #<pr_number> — <date>
- <flag_name_2> — #<pr_number> — <date>
...

:page_facing_up: Tracking: <notion-flags-tracker-url>

4. Update Notion (Optional)

If Notion MCP is available, for each removed flag:

• Search for the flag in the Notion database
• Update the page with:
• `Code removal date` = today's date (YYYY-MM-DD)
• `Owner` = git user name

5. Confirm to User

Output summary:

## Feature Flag Cleanup Complete

| Metric | Value |
|--------|-------|
| Flags removed | <count> |
| PR | #<pr_number> |
| Progress | <removed>/<total> (<percentage>%) |

### Flags Removed
- <flag_1>
- <flag_2>
...

### Actions
| Action | Status |
|--------|--------|
| status.md | Already updated |
| Slack posted | Message sent to #flags-removal |
| Notion | Updated / Not available |

Error Handling

• **No PR found:** Prompt user to provide PR number explicitly
• **No flags found in PR body:** Ask user to list the flags manually
• **Slack error:** Show message for manual posting

Notes

• This skill is meant to be run AFTER a flag removal PR is ready/merged
• The status.md should be updated as part of the removal PR itself
• Slack channel #flags-removal ID: C0AST27EWTA
• Part of Firebase Feature Flags Maintenance initiative
