Firewatch

Firewatch

Query, filter, and act on GitHub PR activity using the Firewatch CLI (fw).

Quick Start

fw --refresh --summary --open    # Sync and see what needs attention
fw --type comment --pr 42       # Comments on PR #42
fw --type comment | jq 'select(.author != .pr_author)'  # External feedback only

Core Concepts

JSONL Output

Firewatch outputs one JSON object per line. Each entry is denormalized — it contains full PR context (title, state, author, labels) so you never need joins.

fw --type comment --limit 1

{
  "id": "IC_kwDOK...",
  "type": "comment",
  "subtype": "review_comment",
  "author": "alice",
  "body": "Consider adding error handling here",
  "file": "src/auth.ts",
  "line": 42,
  "pr": 123,
  "pr_title": "Add user authentication",
  "pr_state": "open",
  "pr_author": "bob",
  "created_at": "2025-01-14T10:00:00Z"
}

Entry Types

Querying

Filter Flags

fw --type comment              # By type
fw --since 24h                 # By time (30s, 5m, 24h, 7d, 2w, 1mo)
fw --pr 42                    # By PR number
fw --author alice              # By author
fw --open                      # Open PRs only
fw --active                    # Open or draft PRs
fw --mine                      # PRs assigned to me
fw --reviews                   # PRs I need to review

Combine filters (AND logic):

fw --type review --author alice --since 7d --open

Aggregation

Per-PR summary instead of individual entries:

fw --summary --open

Composing with jq

CLI filters handle common cases; jq handles everything else:

# Only approved reviews
fw --type review | jq 'select(.state == "approved")'

# Comments mentioning "TODO"
fw --type comment | jq 'select(.body | test("TODO"; "i"))'

# External feedback (not self-comments)
fw --type comment | jq 'select(.author != .pr_author)'

# Count by type
fw | jq -s 'group_by(.type) | map({type: .[0].type, count: length})'

Tip: Use CLI filters first, then jq. CLI filters are faster because they skip JSON parsing for non-matching entries.

See references/jq-cookbook.md for more patterns.

Taking Action

Post a Comment

fw add 42 "LGTM, merging!"

Reply to a Review Comment

Every comment entry has an id field:

fw add 42 "Fixed in latest commit" --reply IC_kwDOK...

Reply and Resolve

fw add 42 "Done" --reply IC_kwDOK... --resolve

Resolve Without Replying

fw close IC_kwDOK...

Resolve multiple threads:

fw close IC_abc IC_def IC_ghi

Staleness Tracking

Review comments can become stale when the file is modified. Run fw check to populate staleness data:

fw check

Then query for unaddressed comments:

fw --type comment | jq 'select(.file_activity_after.modified == false)'

The file_activity_after field shows:

• modified — Whether file was changed after the comment
• commits_touching_file — How many commits touched the file
• latest_commit — SHA of the most recent commit to the file

Graphite Stack Support

Firewatch integrates with Graphite for stack-aware queries. When syncing in a repo with Graphite stacks, entries include stack metadata:

fw --refresh   # Auto-detects Graphite stacks

Stack Fields

Entries gain a graphite object:

{
  "graphite": {
    "stack_id": "abc123",
    "stack_position": 2,
    "stack_size": 4,
    "parent_pr": 101
  }
}

• stack_position — 1 is the base (closest to main), higher = further up
• file_provenance — Which PR in the stack introduced each file

Quick Stack Queries

# All entries with stack metadata
fw | jq 'select(.graphite != null)'

# Base PRs only (bottom of stack)
fw --summary | jq 'select(.graphite.stack_position == 1)'

# Comments where file originated in a different PR
fw --type comment | jq 'select(.file_provenance.origin_pr != .pr)'

Stack Workflows

For detailed Graphite workflows (querying stacks, cross-PR fixes, commit patterns):

• graphite/stack-queries.md — Querying stack data
• graphite/cross-pr-fixes.md — File provenance and fixing in the right PR
• graphite/commit-workflow.md — gt modify vs gt amend -a

Agent Tips

1. CLI filters first, then jq — More efficient than jq-only filtering
2. Denormalized = no joins — Each entry has full PR context
3. Entry IDs for actions — Use id field with --reply and fw close
4. Run fw check for staleness — Populates file_activity_after field
5. Check .graphite for stacks — Null if not in a Graphite stack
6. File provenance for cross-PR fixes — See graphite/cross-pr-fixes.md
