plan

A planning workflow that breaks a software specification into dependent tasks and creates planning records in a project’s .tasker directory.

In plain words
What is it for?
Asking for the target project directory, mapping required capabilities, defining task dependencies, and producing task, artifact-map, and validation-report files.
Why use it?
It helps turn a broad specification into an ordered set of work that can be carried out and checked.

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

plan 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 — 547 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Workflow

CRITICAL: This is the PLAN skill. Do NOT call Skill(execute) or Skill(tasker:execute). Follow the instructions below directly.

IMPORTANT: All tasker working files go in $TARGET_DIR/.tasker/. Do NOT create 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).

Decompose a specification into an executable task DAG. This is Phase 2 of the tasker workflow:

/specify → /plan → /execute

Input Requirements

  • Spec from /specify: {TARGET}/docs/specs/<slug>.md
  • Capability Map: {TARGET}/docs/specs/<slug>.capabilities.json
  • FSM Artifacts (optional): {TARGET}/docs/state-machines/<slug>/

Output

  • Task DAG: .tasker/tasks/T001.json, T002.json, etc.
  • Physical Map: .tasker/artifacts/physical-map.json
  • Validation Report: .tasker/reports/task-validation-report.md

MANDATORY FIRST STEP: Ask for Target Project Directory

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

Step 1: Ask for Target Directory

Use AskUserQuestion to ask:

What is the target project directory?

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

Validation:

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

if [ ! -d "$TARGET_DIR" ]; then
    # For new projects, check parent exists
    PARENT=$(dirname "$TARGET_DIR")
    if [ -d "$PARENT" ]; then
        echo "Directory will be created: $TARGET_DIR"
        mkdir -p "$TARGET_DIR"
    else
        echo "Error: Parent directory does not exist: $PARENT"
        # Re-ask for target_dir
    fi
fi

Step 2: Check for Existing Session and Initialize

After target_dir is confirmed, check for existing .tasker/ state:

TASKER_DIR="$TARGET_DIR/.tasker"
if [ -f "$TASKER_DIR/state.json" ]; then
    echo "Found existing tasker session at $TASKER_DIR"
    echo "Resuming from saved state..."
    # Read phase from state.json and resume
    tasker state status
else
    echo "No existing session. Initializing..."
    # Initialize directory structure
fi

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.

plan is a skill published in the GitHub repository Dowwie/tasker (19 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 25 tokens to every session and 4,333 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.
