What it does

Complete Subtask is an agent skill from Log2n-io/Typhon. Complete a sub-issue of an umbrella issue - close it, check parent checkbox, update design doc

Its SKILL.md is about 1.5k 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 Agent Workflows, covering Task breakdown and Architecture decision records. It works with GitHub and Model Context Protocol. 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

  • “/complete-subtask”

Requirements

  • Python 3

Workflow steps

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

  1. Fetch Sub-Issue Details
  2. Detect Parent (Umbrella) Issue
  3. Close the Sub-Issue
  4. Update Project Status to Done
  5. Check Checkbox in Parent Issue
  6. Update Design Doc Status (if exists)
  7. Report Summary

What it can do on your machine

Read from SKILL.md and the folder at commit fec10f5. 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

Complete Subtask loads about 1.5k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 553 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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 553 words (~1,521 tokens).

“Mark a sub-issue as done within an umbrella issue workflow. This is the lightweight counterpart to /complete-task — it handles subtask completion without branch cleanup, PR checks, or ADR prompts.”
