tp — Task Plan

Spec-to-task lifecycle manager for AI coding agents.

Break specs into atomic, dependency-ordered tasks. Agents execute them with 2 tool calls instead of hundreds.

Why

AI agents fail at long tasks. Research shows:

• <15 min tasks: 70%+ success (SWE-bench)
• >50 min tasks: ~23% success (SWE-bench Pro)
• Each tool call costs ~200 tokens of agent context

tp solves this with atomic task decomposition and a 2-call architecture:

tp plan --minimal --json       # ONE call: get execution plan
# [agent implements each task, commits each one]
tp done --batch results.ndjson # ONE call: close everything

Token overhead: ~5K (vs ~54K with naive per-task tool calls).

Install

# Go install
go install github.com/deligoez/tp/cmd/tp@latest

# Or build from source
git clone https://github.com/deligoez/tp.git
cd tp && go build -ldflags="-s -w" -o tp ./cmd/tp

# Install Claude Code skill (first time)
npx skills add -g deligoez/tp

# Update skill (after tp updates)
npx skills update -g deligoez/tp

Quick Start

# 1. Create a task file from a spec
tp init spec/my-feature.md

# 2. Add tasks (or use tp import for bulk)
tp add '{"id":"create-model","title":"Create User model","estimate_minutes":8,
  "acceptance":"Model exists. Migration runs.","source_sections":["### User Model"],
  "source_lines":"15-42","depends_on":[]}'

# 3. Get the execution plan
tp plan --minimal --json

# 4. Implement, commit, and close each task
tp done create-model "User model at app/Models/User.php. Migration runs." --gate-passed --auto-commit

Commands

Primary Workflow

tp plan                        # Full execution plan (THE primary command)
tp plan --minimal              # Minimal: id + acceptance only (~80% fewer tokens)
tp plan --compact              # Stripped: no description, source_lines, tags (~40% fewer)
tp plan --from <id>            # Start from a specific task onward
tp plan --level 0,1            # Filter by parallelism levels (multi-agent)
tp commit <id> [reason]        # Stage + structured commit + record SHA
tp commit <id> --files "*.go"  # Selective file staging
tp done <id> <reason>          # Close with implicit claim + verification
tp done <id> --gate-passed     # Relax keyword matching (agent attests gate passed)
tp done <id> --auto-commit     # Stage + commit + close in one call
tp done <id> --covered-by <id> # Close as covered by another done task
tp done <id> --commit <sha>    # Record implementing commit SHA
tp done --batch file.ndjson    # Batch close from NDJSON

Incremental (fallback)

tp next                        # Resume WIP or claim next ready
tp next --peek                 # Preview without claiming

Task State

tp claim <id> [id...]          # open → wip (batch: multiple IDs)
tp claim --all-ready           # Claim all ready tasks at once
tp close <id> <reason>         # wip → done (low-level, prefer tp done)
tp reopen <id>                 # done → open (clears timestamps + SHA)
tp remove <id>                 # Remove task (--force for dep cleanup)
tp set <id> field=value        # Update field (managed fields protected)
tp set --bulk sets.ndjson      # Bulk update from NDJSON {id, field, value}

Query

tp list                        # All tasks
tp list --status open          # Filter by status (open/wip/done)
tp list --tag api              # Filter by tag
tp list --ids                  # IDs only
tp list --compact              # Minimal fields
tp ready                       # Tasks with all deps satisfied
tp ready --first               # First ready task only
tp ready --count               # Count of ready tasks
tp ready --ids                 # Ready task IDs only
tp show <id>                   # Full details + spec_excerpt + blocks
tp status                      # Progress summary (open/wip/done counts)
tp blocked                     # Tasks waiting on unsatisfied deps
tp graph                       # Dependency tree
tp graph --tag api             # Filter by tag
tp graph --from <id>           # Subtree from a task
tp stats                       # Parallelism analysis
tp report                      # Per-task duration + estimation accuracy

Spec & Validation

tp lint spec.md                # Spec quality + structured element detection
tp validate                    # Task file validation (--strict for atomicity errors)
tp validate                    # Includes line coverage check (source_lines vs spec)

Data

tp init spec.md                # Create empty task file
tp add <json>                  # Add task (--stdin for piped input)
tp add --bulk tasks.ndjson     # Bulk add from NDJSON
tp import file.json            # Import + validate (--force to overwrite + relax atomicity)

Global Flags

--file <path>    Explicit task file path
--json           Force JSON output (default when piped)
--compact        Minimal JSON (~40% smaller)
--quiet          Suppress info messages
--no-color       Disable colored output

Task File Discovery

tp finds your .tasks.json automatically:

1. --file flag (highest priority)
2. TP_FILE environment variable
3. Auto-detect: scans current directory, then one level of subdirectories

# Set once, use everywhere
export TP_FILE=spec/project.tasks.json

Task File Format

Tasks live in a JSON file alongside the spec:

spec/
  my-feature.md              # spec (source of truth)
  my-feature.tasks.json      # tasks (derived, git-tracked)

Each task is atomic — one commit, one verb, ≤15 minutes:

{
  "id": "create-model",
  "title": "Create User model",
  "status": "open",
  "estimate_minutes": 8,
  "acceptance": "Model exists. Migration runs.",
  "depends_on": [],
  "source_sections": ["### User Model"],
  "source_lines": "15-42"
}

JSON Field Aliases

deps is accepted as shorthand for depends_on:

{"id": "api", "deps": ["model"], ...}

Closure Verification

tp prevents lazy task closure. Every tp done and tp close verifies:

• Keyword matching: reason must address each acceptance criterion
• Minimum length: reason ≥ half the acceptance text
• Forbidden patterns: rejects "deferred", "will be done later", single-word reasons

# This fails:
tp done create-model "done"
# error: closure reason must address each acceptance criterion with evidence

# This passes:
tp done create-model "User model at app/Models/User.php. Migration runs clean."

Relaxed Modes

# --gate-passed: skip keyword matching (agent attests quality gate passed)
tp done task-1 "2559 tests pass, PHPStan level 8 clean" --gate-passed

# --covered-by: task satisfied by another done task (not a deferral)
tp done qa-delegation "test #26 covers this" --covered-by qa-tests

Structured Commits

tp commit generates conventional commit messages with task metadata:

tp commit auth-model "Model and migration created"

feat(auth-model): Create User model

Model and migration created

Task: auth-model
Acceptance: Model exists. Migration runs.

Or commit + close in one call:

tp done auth-model "evidence" --gate-passed --auto-commit

Spec Quality

tp lint detects structured elements (tables, numbered lists, code blocks) for decomposition verification:

tp lint spec.md --json | jq .structured_elements

tp validate checks line coverage — verifying that task source_lines cover the entire spec:

tp validate --json | jq .checks.line_coverage

AX (Agent Experience)

tp is designed for AI agents first (AX), not humans (DX):

Principle	How
Minimal tokens	--minimal ~80%, --compact ~40% smaller. 2-call architecture saves ~90%
Batch parity	tp claim --all-ready, tp done --batch, tp set --bulk
Actionable errors	Every error includes hint field with recovery action
Structured commits	tp commit generates conventional commit messages with task metadata
Implicit claim	tp done and tp commit auto-claim open tasks
WIP resume	tp next returns existing WIP task (crash recovery)
Covered-by	Close tasks covered by other tasks without duplicate work
Estimation calibration	tp add warns when historical estimates are consistently high
Duration tracking	tp report shows per-task timing and estimation accuracy

Claude Code Integration

tp ships with a Claude Code skill via the Agent Skills standard:

# Install skill (first time)
npx skills add -g deligoez/tp

# Update skill (after tp updates)
npx skills update -g deligoez/tp

The skill teaches Claude the 2-call workflow, decomposition rules, NDJSON format, closure verification, and commit conventions automatically.
