Task Discovery

Query a decision task graph and group matching labels by worker type or task kind.

Prerequisites

Install uv. Read-only Taskcluster access does not need authentication.

Usage

DISCOVER=~/.claude/skills/task-discovery/scripts/discover.py

# Audit the current autoland task graph.
uv run "$DISCOVER" -w win11-64-24h2 --branch autoland -o summary

# Generate exact task labels for mach try fuzzy.
uv run "$DISCOVER" -w win11-64-24h2 --exact -k test -o query

# List all worker types in the graph.
uv run "$DISCOVER" --list-worker-types --branch autoland

Run uv run "$DISCOVER" --help for regex matching, output formats, and timeouts.

Gotchas

• The default branch is mozilla-central. Use --branch autoland for current migration planning.
• Worker matching is a substring search by default. Use --exact when suffix variants such as -gpu, -hw, or -source must not match.
• Task graphs can exceed 30 MB. Increase --timeout on slow links.
