What it does

Long Task Design is an agent skill from suriyel/longtaskforagent. Use when SRS doc exists but no design doc and no feature-list.json - take the approved SRS as input and produce an architecture/design document focused on HOW to build it

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 Architecture decision records.

When your agent uses it

  • Tasks that involve Architecture decision records

Example prompts

  • “/long-task-design”

Workflow steps

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

  1. Read SRS & UCD & Extract Design Inputs
  2. Explore Technical Context
  3. Propose Approaches
  4. Section-by-Section Approval
  5. Write Design Document
  6. Transition to ATS

What it can do on your machine

Read from SKILL.md and the folder at commit ca67fe1. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

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

  • Network

    No URLs in SKILL.md.

    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

Long Task Design loads about 4.5k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 2,202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
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

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,202 words (~4,549 tokens).

“LANGUAGE RULE: You MUST respond to the user in Chinese (Simplified). All generated documents, reports, and user-facing output must be written in Chinese. Skill names, code identifiers, and JSON field names remain in English.”
