Phase Triage
Phase agent that triages a Linear ticket — expands acronyms, classifies (feature/bug/docs/refactor/chore), identifies genuine blockers (a semantic second-pass over the backlog — NOT a prose scrape; CTL-838), estimates scope, writes triage.json, and posts a triage analysis comment to Linear. Triage completion is signaled by that comment plus the local triage.json — there is no `triaged` label. Emits phase.triage.complete.<TICKET> on success and phase.triage.failed.<TICKET> on error. Dispatched by the phase-agent orchestrator (CTL-452) via slash command — `user-invocable: true` so the dispatcher's `claude --bg "/catalyst-dev:phase-triage ..."` resolves.

From the source SKILL.md
Greenfield phase agent shipped in CTL-451 (Initiative 1 Phase 5). Reads a Linear ticket, produces a structured triage analysis, and lands the analysis as a Linear comment + label so subsequent phase agents (research, plan, …) can rely on the classification.
What this skill does
Phase Triage is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/phase-triage/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Phase Triage Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 158,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Phase Triage skill?
Use Phase Triage when your Claude Code task falls under the Engineering category — specifically in the code quality area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Phase Triage" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Phase Triage skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Phase Triage is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
