execute

An execution step in a task-management workflow that runs planned work through separate subagents. A task DAG is a dependency-aware list showing which tasks can run and which must wait.

In plain words
What is it for?
Use it after the planning phase to run the task list, collect each result, and produce an evaluation report.
Why use it?
It prevents execution from starting before a plan and its task files are ready.

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

execute 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.

The opening of the file, as written. The whole thing — 495 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Execute Workflow

CRITICAL: This is the EXECUTE skill. Only use this after /plan has completed and task files exist in .tasker/tasks/. If no tasks exist, tell the user to run /tasker:plan first.

IMPORTANT: All tasker working files are in $TARGET_DIR/.tasker/. Do NOT create or use any other directories like project-planning/, planning/, or schemas/ at the target project root. The .tasker/ directory is the ONLY location for tasker artifacts (including .tasker/schemas/ for JSON schemas).

Execute a task DAG via isolated subagents. This is Phase 3 of the tasker workflow:

/specify → /plan → /execute

Input Requirements

  • Task DAG from /plan: .tasker/tasks/T001.json, T002.json, etc.
  • State file: .tasker/state.json with phase = "ready" or "executing"

Output

  • Working implementation in target directory
  • Task results: .tasker/bundles/T001-result.json, etc.
  • Evaluation report: .tasker/reports/evaluation-report.txt

MANDATORY FIRST STEP: Ask for Target Project Directory

ALWAYS ask for target_dir FIRST before anything else. No guessing, no inference from CWD.

Use AskUserQuestion to ask:

What is the target project directory?

Free-form text input. User must provide an absolute or relative path.

After target_dir is confirmed:

TARGET_DIR="<user-provided-path>"
# Convert to absolute path
TARGET_DIR=$(cd "$TARGET_DIR" 2>/dev/null && pwd)

TASKER_DIR="$TARGET_DIR/.tasker"

# Verify .tasker/ exists and has state
if [ ! -f "$TASKER_DIR/state.json" ]; then
    echo "Error: No tasker session found at $TASKER_DIR"
    echo "Run /plan first to create a task plan."
    exit 1
fi

Execute Prerequisites

# Verify planning is complete
tasker state status
# Phase must be: ready, executing, or have tasks

Git Repository Initialization (MANDATORY)

Before any implementation begins, check if the target repository has git initialized. If not, initialize it:

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.

execute is a skill published in the GitHub repository Dowwie/tasker (19 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 3,556 once invoked, about $0.0001 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.
