ase-task-implement

A task-plan implementation workflow that applies the current software task plan in a separate worktree.

In plain words
What is it for?
Use it to implement a planned feature, fix, refactor, or other software change.
Why use it?
It turns an approved plan into code while keeping the work isolated from the main working directory.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ase-task-implement scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Procedure

  1. Determine Task:

    1. Set initially, with any leading and trailing whitespace stripped. Inherit the always existing from the current context. Inherit the always existing from the current context. Do not output anything.

    2. React on task id:

  2. Determine Operation:

    1. Determine the current task plan content:

    2. If the is still empty, complain and tell the user to use the ase-code-resolve, ase-code-refactor, ase-code-craft, or ase-task-edit skills first to create a task plan. Then immediately stop processing this skill.

    3. Internalize the tenets stated by the plan:

  3. Prepare WorkTree:

    1. Set . The worktree is never named by its own option value: it always carries the unique task id, so the worktree directory and its branch stay unambiguously tied to the very task plan implemented in them. The task id is a plain identifier by construction, hence it is directly usable as both a directory and a branch name. Do not output anything.

    2. Determine the worktree directory by calling the ase_worktree_path(id: "<worktree-name/>", create: true) tool of the ase MCP server and capturing its output into .

      You MUST NEVER assemble this path yourself, as only this tool rejects a path leading through a symbolic link, through a non-directory, or out of the repository -- a path git worktree add would otherwise silently follow and thereby write outside the repository.

    3. Determine the existing worktrees and existing branches by running the corresponding commands (taken exactly as given) and capturing their outputs:

      git worktree list --porcelain

      git branch --list

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ase-task-implement is a skill published in the GitHub repository rse/ase (47 stars, last pushed 4d ago), licensed Apache-2.0. It adds 44 tokens to every session and 3,047 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
