Task Forest

Task Forest

Language Policy

Write skill instructions in English. When interacting with the user or generating task titles, node fields, proposals, reports, or exported user-facing content, use the user's language. Default to Chinese when the user's language is unknown.

Role

Maintain repo-local task structure. Record long-running goals, subtasks, dependencies, progress, deviations, todos, and session history under the current workspace. Export an offline HTML view of the task graph.

Portability

Resolve paths from the directory that contains this SKILL.md. Use the available Python command on the host (python3, python, or py -3). The scripts are intended for macOS, Windows, and Linux with Python 3 and the standard library. In portable builds, agents may set COMPASS_AGENT_NAME or AGENT_NAME when they want graph history to record the calling agent.

Core Principles

1. Write task-forest data only through scripts/task_forest.py; never edit files under .agent-workbench/task-forest/ directly.
2. The internal model is a DAG. The default presentation is a forest: one primary child_of parent per node, contributes_to for secondary ownership, and depends_on for execution prerequisites.
3. If user intent is unclear, apply $task-clarifier before task graph work. If intent is clear enough, present a proposal and wait for confirmation before applying it.
4. Keep unconfirmed assumptions in proposals. Write formal graph changes only after confirmation.
5. When execution diverges from the user's requirement, record a deviation and move related tasks to review_needed or wait for user confirmation.
6. Store canonical data in the current workspace at .agent-workbench/task-forest/. Store only lightweight registry data in the global SQLite index.
7. In concurrent sessions, read and write through the CLI so locking and stale-hash checks can run.
8. Treat HTML export as a primary product surface. Changes to the HTML template must satisfy references/html-visualization-contract.md and pass scripts/validate_task_forest_export.py.

CLI

Resolve <skill-dir> to the directory that contains this SKILL.md. Use the available Python command for the host (python3, python, or py -3). Examples use python3; adapt only the Python executable name when needed.

python3 <skill-dir>/scripts/task_forest.py --help

The default workspace is the current working directory. To target a specific workspace:

python3 <skill-dir>/scripts/task_forest.py init \
  --workspace /path/to/repo

Common commands:

python3 <skill-dir>/scripts/task_forest.py init

python3 <skill-dir>/scripts/task_forest.py add-node \
  --kind global_task \
  --title "Maintain the local agent workbench" \
  --requirement "Task data stays inside the workspace" \
  --acceptance "The task graph can be exported to HTML"

python3 <skill-dir>/scripts/task_forest.py add-node \
  --title "Implement task graph HTML export" \
  --parent TF-0001 \
  --estimate 120 \
  --difficulty medium

python3 <skill-dir>/scripts/task_forest.py todo
python3 <skill-dir>/scripts/task_forest.py export
python3 <skill-dir>/scripts/task_forest.py validate

Session Close Workflow

When the user asks to update the task forest, close the current session, or maintain the task list from the conversation:

1. Run init to ensure the data directory exists.
2. Run list --json and todo --json to read current nodes and open work.
3. Analyze the session and create candidate changes only: new nodes, node updates, edges, deprecations, deviations, or questions.
4. If the session goal is unclear, ask which goal this conversation mainly served.
5. If the goal is clear enough, show the proposal: where each new node goes, how it relates to existing tasks, and which fields would change.
6. Save the candidate changes as a proposal. Apply with proposal-apply --yes only after user confirmation.
7. After applying, run validate and export, inspect the HTML against references/html-visualization-contract.md, and tell the user the HTML path.

Proposal JSON fields and invariants live in references/schema.md. Complex session-close reasoning lives in references/session-close-workflow.md.

Read references/goal-alignment.md when judging how a task serves a global goal, whether it can achieve the user's purpose, or which candidate task plan to offer. Clarification methods come from $task-clarifier; task-forest owns graph meaning, candidate task structure, and proposal writes.

Read references/node-types.md only when adding or classifying nodes.

Concurrency and multi-session rules live in references/concurrency.md. Proposals store base_graph_hash; application rejects stale proposals by default. Use --allow-stale only after manual conflict review.

Outputs And Integration

Exports are fixed at:

.agent-workbench/task-forest/exports/task-forest.graph.json
.agent-workbench/task-forest/exports/task-forest.todos.json
.agent-workbench/task-forest/exports/task-forest.timeline.json
.agent-workbench/task-forest/exports/task-forest.html

gap-router and local-agent-control-room read these exports. They must leave canonical task-forest data unchanged. Field contracts live in references/integration-contract.md.

The CLI updates a lightweight global registry when possible during init, export, validate, proposal-save, and proposal-apply:

~/.agent-workbench/agent-workbench.sqlite3

The registry stores workspace paths, task-forest paths, export paths, export hashes, node/edge/status counts, command status, and error summaries. It omits node bodies, edge bodies, history snapshots, HTML, proposal content, and full conversation summaries. Use AGENT_WORKBENCH_DB to set another registry path. Set TASK_FOREST_DISABLE_GLOBAL_REGISTRY=1 to disable the global registry.

Full rebuild regression:

python3 <skill-dir>/scripts/validate_task_forest_export.py --skill-dir <skill-dir>

The validator creates a temporary workspace, initializes task-forest, builds a sample DAG with multiple states and edge types, runs validate/export, and checks exported JSON and HTML behavior.

Boundaries

• Explicit invocation is the reliable way to run this skill at session end.
• Low-confidence goal inference must become a question or stay in a proposal.
• Prefer deprecated for removed tasks so history remains reviewable.
• Estimates must include confidence. Use unknown or low confidence when evidence is thin.
