What it does
Start Subtask is an agent skill from Log2n-io/Typhon. Start working on a sub-issue of an umbrella issue - updates status, validates dependencies, updates design doc
Its SKILL.md is about 1.6k 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 Agent Workflows, covering Task breakdown and Architecture decision records. It works with GitHub. The repository describes itself as: A microsecond-latency ACID database engine with a native Entity-Component-System data model, built for real-time systems.
When your agent uses it
- Tasks that involve Task breakdown
- Tasks that involve Architecture decision records
Example prompts
- “/start-subtask”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Fetch Sub-Issue Details
- Detect Parent (Umbrella) Issue
- Validate Parent Status
- Check Dependencies
- Update Project Status to In Progress
- Update Design Doc Status (if exists)
- Report Summary
What it can do on your machine
Read from SKILL.md and the folder at commit da2018e. 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
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, 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
Start Subtask loads about 1.6k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 517 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 517 words (~1,633 tokens).
“Begin work on a sub-issue within an umbrella issue workflow. This is the lightweight counterpart to /start-task -- it handles subtask activation without branch creation or design doc creation (those already exist from the umbrella).”
