What it does

Task Prune is an agent skill from jiangzhe/doradb. Inspect and optionally remove completed Doradb task worktrees and their local branches with deterministic safety checks. Use when listing cleanup candidates or pruning clean task worktrees marked implemented both locally and on origin/main, from the main dispatch checkout; never delete remote branches.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Git worktrees. The repository describes itself as: DoraDB - Async Rust storage engine. The licence is Apache-2.0.

When your agent uses it

  • Listing cleanup candidates
  • Pruning clean task worktrees marked implemented both locally and on origin/main
  • From the main dispatch checkout
  • Never delete remote branches

Example prompts

  • “/task-prune”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Start with a dry run
  2. Require the output to list all worktrees before any removal decision.
  3. Exclude the main worktree with reason main_dispatch_branch.
  4. Inspect every non-main worktree under .worktrees/ whose basename is a
  5. Mark a worktree safe only when all conditions hold
  6. Report candidates under safe_to_purge, unfinished, and excluded, with
  7. Apply removal only after explicit user intent

What it can do on your machine

Read from SKILL.md and the folder at commit 3291b68. 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:

    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Task Prune loads about 551 tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 235 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~551

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.

description
Inspect and optionally remove completed Doradb task worktrees and their local branches with deterministic safety checks. Use when listing cleanup candidates or pruning clean task worktrees marked implemented both locally and on origin/main, from the main dispatch checkout; never delete remote branches.

Task Prune Workflow

Use this skill only from the main dispatch worktree. The underlying tool calls this operation purge-worktrees; keep that command name unchanged.

Required Flow

  1. Start with a dry run:
bash
tools/task.rs purge-worktrees
  1. Require the output to list all worktrees before any removal decision.
  2. Exclude the main worktree with reason main_dispatch_branch.
  3. Inspect every non-main worktree under .worktrees/ whose basename is a six-digit task id, using that worktree's own docs/tasks/<task-id>-*.md document.
  4. Mark a worktree safe only when all conditions hold:
    • its matching task document has status: implemented;
    • the worktree is clean;
    • exactly one matching docs/tasks/<task-id>-*.md document on origin/main has status: implemented;
    • it contains no other registered worktree. The task document on origin/main is the completion authority; neither a same-name remote task branch nor local-tip ancestry is required. Apply mode refreshes origin before checking eligibility; dry runs use locally available refs.
  5. Report candidates under safe_to_purge, unfinished, and excluded, with reasons for every non-safe worktree.
  6. Apply removal only after explicit user intent:
bash
tools/task.rs purge-worktrees --apply

Removal Boundary

Apply mode may act only on direct children of the dispatch root matching .worktrees/<six-digit-task-id>. It may remove only:

  • the local worktree via git worktree remove;
  • the local branch via git branch -D.

Never delete a remote branch. Treat missing task documents, non-implemented status, dirty worktrees, missing origin/main, missing or ambiguous task documents on origin/main, non-implemented status on origin/main, or nested registered worktrees as hard reasons to retain the worktree.
