What it does
Understand Issue is an agent skill from mastra-ai/mastra. Investigate a GitHub issue or reported bug the way a seasoned maintainer would — form an independent model before reading the thread's theories, trace the mechanism and history, verify the diagnosis, and return a concise briefing with a verdict and fix direction. Use for triage, root-cause analysis, or re-investigation.
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/recipes.md` and `references/templates.md`).
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
- Root-cause analysis
- Re-investigation
Example prompts
- “/understand-issue”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Build your own model
- Read the thread and prior art
- Diagnose like a maintainer
- Recover history when it can change the diagnosis
- Verify the diagnosis
- Decide and brief
What it can do on your machine
Read from SKILL.md and the folder at commit fecbeda. 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:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Understand Issue loads about 3.1k tokens when it runs, and up to ~4.9k if it reads all its reference files. Until then it costs about 85 tokens; SKILL.md has 1,874 words of instructions outside code blocks.
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 1,874 words (~3,139 tokens).
“Investigate the issue as a maintainer deciding what is actually wrong and what should happen next. Help the human understand it without turning the investigation into a walkthrough. Run uninterrupted to a concise front page, then stay available inside the…”
