What it does

Long Task Explore is an agent skill from suriyel/longtaskforagent. Use for on-demand deep exploration of an existing codebase - analyzes architecture, data flow, domain model, API surface, dependencies, and code health

Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/exploration-dimensions.md`).

It sits in Development, covering Code quality.

When your agent uses it

  • On-demand deep exploration of an existing codebase - analyzes architecture
  • Tasks that involve Code quality

Example prompts

  • “/long-task-explore”

Workflow steps

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

  1. Parse Arguments & Announce
  2. Project Detection
  3. Dispatch Locator SubAgent (Phase 1 — Breadth-First Scan)
  4. Dispatch Analyzer + Pattern-Finder (Phase 2 — Parallel Deep Dive)
  5. Synthesize Findings
  6. Write Output
  7. Present Summary

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 bash).

    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 Explore loads about 2.7k tokens when it runs, and up to ~5.5k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 961 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~2.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.5k

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 961 words (~2,655 tokens).

“Explore an existing codebase to produce a structured understanding document. Dispatches specialized SubAgents to locate key structures, analyze architecture and data flow, and measure code health.”
