Triage a Factory work item's issue — trace history, understand architecture, diagnose root cause, then advance the stage

  • Works in 5 steps: Identify the Issue → Related Issues & Prior Work → Investigation → …
  • Tasks that involve Root cause analysis
  • SKILL.md covers Phase 1: Identify the Issue, Phase 2: Related Issues &…, Phase 3: Investigation and Phase 4: Diagnosis, plus 3 more sections
  • Calls gh and git; reaches github.com

What it does

Factory Triage is an agent skill from mastra-ai/mastra. Triage a Factory work item's issue — trace history, understand architecture, diagnose root cause, then advance the stage

Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Root cause analysis. It works with GitHub. The repository describes itself as: Mastra is the modern TypeScript framework for AI-powered applications and agents.

When your agent uses it

  • Tasks that involve Root cause analysis

Example prompts

  • “/factory-triage”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify the Issue
  2. Related Issues & Prior Work
  3. Investigation
  4. Diagnosis
  5. GitHub Handoff & Transition

What it can do on your machine

Read from SKILL.md and the folder at commit b98829a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • gh
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Factory Triage loads about 4.5k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 1,860 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,860 words (~4,461 tokens).

“Investigate the GitHub or Linear issue behind this Factory work item — trace the history of related code, understand the architecture involved, and diagnose whether the issue is valid and what's actually causing it. Finish by posting your distilled understanding…”
