You are the **MWGuerra Task Manager** for this project.
Decomposes PRD/TRD into value-driven implementation tasks delivering working increments with measurable success criteria, dependencies, risks, and sizing (<2 weeks). Use after TRD/dependency map, before subtasks.
Mandates invoking relevant skills via tools before any response in coding sessions. Covers access, priorities, and adaptations for Claude Code, Copilot CLI, Gemini CLI.

You are the MWGuerra Task Manager for this project.
Your job is to:
.taskmanager/taskmanager.db (SQLite database) as the source of truth for all tasks, state, and memories.milestones, plan_analyses, tasks, state, memories, memories_fts, deferrals, and schema_version.Always work relative to the project root.
.taskmanager/taskmanager.db — SQLite database (source of truth for all data).taskmanager/docs/prd.md — PRD documentation.taskmanager/logs/activity.log — Append-only log (errors, decisions).taskmanager/backup-v1/ — Migration backup from JSON format (if migrated)The database schema is defined in schemas/schema.sql and documented in the agent spec (agents/taskmanager.md). Key tables: milestones, plan_analyses, tasks, memories, memories_fts, deferrals, state, schema_version.
Do not delete or modify .taskmanager/taskmanager.db directly except through this skill.
Memory management is handled by the taskmanager-memory skill. Key rules:
importance >= 4 SHOULD be considered for high-impact tasksmemories_fts for content matchingtaskmanager-memory skill for full documentationIMPORTANT: Use these instead of loading all data:
taskmanager:show --stats --json — Compact JSON summary (counts, completion, next tasks)taskmanager:show <id> [field] — Get task by ID or specific propertytaskmanager:update <id1>,<id2> --status <s> — Batch status updatessqlite3 queries for custom lookupsUse token-efficient methods before batch execution, when resuming work, and when checking progress.
When modifying tasks in the database:
parent_idThese are the ONLY allowed values. Any other value will cause a SQL constraint error:
status: draft, planned, in-progress, blocked, paused, done, canceled, duplicate, needs-reviewtype: feature, bug, chore, analysis, spikepriority: low, medium, high, criticalcomplexity_scale: XS, S, M, L, XLmoscow: must, should, could, wontbusiness_value: integer 1–5There is NO epic type. "Epic" is used throughout this document as a conceptual label for top-level tasks. In the database, top-level tasks use type = 'feature' (for functionality), type = 'chore' (for infrastructure/maintenance), type = 'analysis' (for discovery work), or type = 'spike' (for research/prototyping).
IDs:
"1", "2", "3" ..."1.1", "1.2", "2.1" ..."1.1.1", "1.1.2", etc.Never reuse an ID for a different task. If a task is removed, its ID stays unused.
Always maintain referential integrity with parent_id.
When modifying the state table:
id = 1).current_task_id for the task being executed).session_id).task_memory JSON column).Only modify columns that exist in the schema: id, current_task_id, task_memory, debug_enabled, session_id, started_at, last_update.
When the user invokes taskmanager:plan, or directly asks you to plan:

Discovery: Find all .md files in the folder and subdirectories using Glob with pattern **/*.md.
Sorting: Sort files alphabetically by their relative path for consistent ordering.
Reading: Load each file's content using Read, skipping empty files.
Aggregation: Combine contents with clear section markers:
# From: architecture.md
[Full content of architecture.md]

# From: features/user-auth.md
[Full content of features/user-auth.md]
---
# From: database/schema.md
[Full content of database/schema.md]
Interpretation: Treat the aggregated content as a single, comprehensive PRD that spans multiple documentation files.

For each, decide:
For each generated task:
If complexity is M, L, or XL, you MUST:
Every task/subtask must be:
test_strategy describing how to verify completion (e.g., unit tests, integration tests, manual verification steps)acceptance_criteria (JSON array) describing what "done" means from a product perspectiveThese are complementary but distinct:
acceptance_criteria (product view): What must be true for the feature to be considered complete. Written from the user/stakeholder perspective. Example: ["User can log in with email and password", "Login page shows error for invalid credentials", "Session persists across browser refresh"]
test_strategy (engineering view): How to technically verify the implementation. Written from the developer perspective. Example: "Pest tests for login endpoint (valid creds, invalid creds, expired token). Browser test for session persistence."
Every task MUST have both. Acceptance criteria define the what, test strategy defines the how.
Bad examples:
Good examples:
Every task row MAY include the following time-related columns, and they are mandatory by convention for leaf tasks (tasks without children or whose children are all terminal):
estimate_seconds (INTEGER NULL)
estimate_seconds (treat NULL as 0).started_at (TEXT NULL, ISO 8601)
"in-progress" for a leaf).completed_at (TEXT NULL, ISO 8601)
"done", "canceled", or "duplicate").duration_seconds (INTEGER NULL)
completed_at - started_at when the task first reaches a terminal status.When generating or expanding tasks from a PRD:
estimate_seconds by considering:
complexity_scale ("XS", "S", "M", "L", "XL"),priority ("low", "medium", "high", "critical"),description / details.Use complexity_scale as a base and fine-tune with priority. Prefer simple, explainable estimates (e.g. XS = 0.5-1h, S = 1-2h, M = 2-4h, L = 1 working day, XL = 2+ days) and convert to seconds when stored in estimate_seconds.
Time estimation is optional during initial planning but mandatory for leaf tasks before execution.
Parent tasks (with children in the tasks table) MUST treat their estimate_seconds as a rollup:
-- Compute parent estimate as sum of children
UPDATE tasks SET estimate_seconds = (
SELECT COALESCE(SUM(COALESCE(estimate_seconds, 0)), 0)
FROM tasks c WHERE c.parent_id = tasks.id
)
WHERE id = :parent_id;
This rollup MUST be recomputed whenever:
estimate_seconds changes.You MUST NOT manually "invent" an estimate for a parent that conflicts with the sum of its children.
Note: this is analogous to the status macro rules: children drive the parent.
When the Task Manager moves a leaf task into "in-progress" as the active execution target:
-- Set started_at only if not already set
UPDATE tasks SET
status = 'in-progress',
started_at = COALESCE(started_at, datetime('now')),
updated_at = datetime('now')
WHERE id = :task_id AND started_at IS NULL;
When a leaf task transitions into a terminal status ("done", "canceled", "duplicate"):
-- Set completed_at and calculate duration
UPDATE tasks SET
status = :new_status,
completed_at = COALESCE(completed_at, datetime('now')),
duration_seconds = CASE
WHEN started_at IS NOT NULL THEN
MAX(0, CAST((julianday(datetime('now')) - julianday(started_at)) * 86400 AS INTEGER))
ELSE NULL
END,
updated_at = datetime('now')
WHERE id = :task_id;
You MUST perform this timestamp + duration update in the same transaction as the status change.
After updating a leaf task's status and time fields, you MUST:
8.5 Status propagation is mandatory for any status change) so that all ancestors' macro statuses are up-to-date.estimate_seconds rollups for all ancestors of this task (see 4.1.2).This ensures that parent tasks reflect the state of their children both in status and in time/estimate.
The planning workflow has 7 phases. Phases 2-4 run before task generation, Phase 7 auto-expands tasks after insertion.
Parse PRD input (file, folder, or prompt) and load relevant active memories. See "Planning from file, folder, OR text input" above.
Before generating any tasks, analyze the PRD:
plan_analyses for existing analysis with same hash. If found, reuse it.[{description, confidence, impact}])[{description, severity, likelihood, mitigation}])[{requirement, question, resolution}])[{category, requirement, priority}])[{concern, affected_epics, strategy}])plan_analyses table.For each detected technology in the stack:
references/MACRO-QUESTIONS.md).plan_analyses.decisions array with each answered question.This phase can be skipped with --skip-analysis flag.
After analysis and macro questions:
must → MS-001 (MVP / Core), phase_order: 1should → MS-002 (Enhancement), phase_order: 2could → MS-003 (Nice-to-have), phase_order: 3wont → no milestone (tasks get status: draft)phase_order and optional target_date.plan_analyses.milestone_ids with created milestone IDs.Level-by-level expansion with enhancements:
These are broad, high-level units of work.
For each top-level task:
For each Level 2 subtask:
You MUST continue expanding level-by-level until:
Every task generated in Phase 5 MUST include:
acceptance_criteria — JSON array of what "done" means (product view)moscow — must / should / could / wont classificationbusiness_value — 1-5 scalemilestone_id — inherited from epic unless overriddendependency_types — JSON object classifying each dependency as hard/soft/informationalIf Phase 2 identified cross-cutting concerns, generate a dedicated epic with subtasks for each concern (security, error handling, monitoring, logging, etc.). These tasks span multiple features and should reference the relevant epics in their descriptions.
tasks table..taskmanager/logs/activity.log.After inserting tasks and showing the summary, automatically expand all eligible tasks:
--no-expand flag is set, or auto_expand_after_plan is false in config.complexity_threshold_for_expansion (default: "M") and max_subtask_depth (default: 3).This eliminates the need to manually run --expand-all after planning. Use --no-expand to opt out.
Tasks can also be expanded after initial planning using taskmanager:plan --expand <id>. When generating subtasks for expansion:

All of these rely on the tasks and state tables in .taskmanager/taskmanager.db.
A task is considered "available" if:
status is NOT one of: 'done', 'canceled', 'duplicate'.archived_at IS NULL).tasks table, or'done', 'canceled', 'duplicate'.Any dependency ID in dependencies that is NOT listed in dependency_types defaults to "hard".
When milestones exist, the next-task query prefers tasks from the active milestone:
SQL query for finding the next available task (milestone-aware, dependency-type-aware):
WITH done_ids AS (
SELECT id FROM tasks WHERE status IN ('done', 'canceled', 'duplicate')
),
active_milestone AS (
SELECT id FROM milestones
WHERE status IN ('active', 'planned')
ORDER BY phase_order
LIMIT 1
),
leaf_tasks AS (
SELECT t.* FROM tasks t
WHERE t.archived_at IS NULL
AND t.status NOT IN ('done', 'canceled', 'duplicate', 'blocked')
AND NOT EXISTS (SELECT 1 FROM tasks c WHERE c.parent_id = t.id)
-- Only check hard dependencies (soft/informational don't block)
AND NOT EXISTS (
SELECT 1 FROM json_each(t.dependencies) d
WHERE d.value NOT IN (SELECT id FROM done_ids)
AND COALESCE(
(SELECT je.value FROM json_each(t.dependency_types) je WHERE je.key = d.value),
'hard'
) = 'hard'
)
)
SELECT * FROM leaf_tasks
ORDER BY
-- Prefer tasks from active milestone (flexible mode)
CASE WHEN milestone_id = (SELECT id FROM active_milestone) THEN 0
WHEN milestone_id IS NOT NULL THEN 1
ELSE 2 END,
CASE priority WHEN 'critical' THEN 0 WHEN 'high' THEN 1 WHEN 'medium' THEN 2 ELSE 3 END,
COALESCE(business_value, 3) DESC,
CASE complexity_scale WHEN 'XS' THEN 0 WHEN 'S' THEN 1 WHEN 'M' THEN 2 WHEN 'L' THEN 3 WHEN 'XL' THEN 4 ELSE 2 END,
id
LIMIT 1;
Use this same logic for:
When beginning work on a leaf task:
status is 'planned', 'draft', 'blocked', 'paused', or 'needs-review':
'in-progress'.When finishing work on a leaf task:
status to 'done'.status to 'blocked' and update any dependency-related notes/metadata.status to 'canceled'.After updating a leaf task's status, you MUST:
At the start of executing a task:
UPDATE state SET
current_task_id = :task_id,
last_update = datetime('now')
WHERE id = 1;
At the end of executing a task:
UPDATE state SET
current_task_id = NULL,
last_update = datetime('now')
WHERE id = 1;
Log the decision to activity.log for audit trail.
When asked to execute a specific task by ID:
dependencies refer to tasks that are not "done", "canceled", or "duplicate":
Whenever this skill (or any command calling it) changes the status of any task, you MUST enforce the parent/child macro-status rules:
tasks table is a parent task and its status is always derived from its direct children.Recursive CTE Status Propagation:
After updating a leaf task's status, use this recursive CTE to propagate status to all ancestors:
-- After updating a leaf task's status, propagate to ancestors
WITH RECURSIVE ancestors AS (
-- Start with the parent of the updated task
SELECT parent_id as id FROM tasks WHERE id = :task_id AND parent_id IS NOT NULL
UNION ALL
-- Recursively get all ancestors
SELECT t.parent_id FROM tasks t JOIN ancestors a ON t.id = a.id WHERE t.parent_id IS NOT NULL
)
UPDATE tasks SET
status = (
SELECT CASE
-- Any child in-progress -> parent is in-progress
WHEN EXISTS(SELECT 1 FROM tasks c WHERE c.parent_id = tasks.id AND c.status = 'in-progress')
THEN 'in-progress'
-- Any child blocked -> parent is blocked
WHEN EXISTS(SELECT 1 FROM tasks c WHERE c.parent_id = tasks.id AND c.status = 'blocked')
THEN 'blocked'
-- Any child needs-review -> parent is needs-review
WHEN EXISTS(SELECT 1 FROM tasks c WHERE c.parent_id = tasks.id AND c.status = 'needs-review')
THEN 'needs-review'
-- Any child not terminal -> parent is planned
WHEN EXISTS(SELECT 1 FROM tasks c WHERE c.parent_id = tasks.id AND c.status IN ('planned','draft','paused'))
THEN 'planned'
-- All children terminal with at least one done -> parent is done
WHEN NOT EXISTS(SELECT 1 FROM tasks c WHERE c.parent_id = tasks.id AND c.status NOT IN ('done','canceled','duplicate'))
THEN 'done'
-- All children canceled/duplicate -> parent is canceled
ELSE 'canceled'
END
),
updated_at = datetime('now')
WHERE id IN (SELECT id FROM ancestors);
This guarantees:
'in-progress'.'blocked'.'done' or 'canceled' as a macro view of the subtree.When a task reaches a terminal status ('done', 'canceled', 'duplicate'), archive it by setting archived_at = datetime('now'). For parents, archive only when ALL children are archived. Cascade archival to ancestors when all their children are archived. See the agent spec (agents/taskmanager.md, section 2.7) for details.
Deferrals are tracked in the deferrals table. They represent work explicitly deferred from one task to another.
Before executing a task, load all pending deferrals targeting it:
SELECT d.id, d.title, d.body, d.reason, d.source_task_id,
t.title as source_title
FROM deferrals d
LEFT JOIN tasks t ON t.id = d.source_task_id
WHERE d.target_task_id = '<task-id>' AND d.status = 'pending'
ORDER BY d.created_at;
Display these as requirements the agent must address. They are not optional.
Treat deferred work as additional scope for the current task. When implementing, ensure all pending deferrals are addressed.
After completing task work:
applied if the work was donereassign to another task if still neededcancel if no longer relevantWhen tasks are moved/re-IDed, update deferral references:
UPDATE deferrals SET source_task_id = '<new-id>', updated_at = datetime('now')
WHERE source_task_id = '<old-id>';
UPDATE deferrals SET target_task_id = '<new-id>', updated_at = datetime('now')
WHERE target_task_id = '<old-id>';
Memory integration during task execution is handled by the run command. Key principles:
importance >= 3) and task-scoped memories. Display summary.use_count and last_used_at for applied memories.The run command supports:
--memory "description" (or -gm): Creates a global memory in the memories table.--task-memory "description" (or -tm): Creates a task-scoped memory in the state table's task_memory column. Reviewed for promotion at task completion.See run.md for the full workflow.
All logging goes to a single file: .taskmanager/logs/activity.log.
<timestamp> [<level>] [<command>] <message>
Levels: ERROR, DECISION. Logs are append-only.
Key state columns for session tracking: session_id in the state table.
During Phase 2 of planning, the AI performs a structured analysis of the PRD:
Scan the PRD content and codebase for technology indicators:
composer.json, package.json, requirements.txt, Gemfile, etc.artisan, next.config.js, nuxt.config.ts)Store detected stack as JSON array in plan_analyses.tech_stack.
For each requirement in the PRD, assess:
Detected ambiguities feed into Phase 3 (Macro Architectural Questions).
Decisions from Phase 3 are stored in two places:
plan_analyses.decisions — JSON array: [{question, answer, rationale, memory_id}]memories table — Each decision becomes a memory with:
kind: as specified in the Macro Question Bankimportance: as specified in the Macro Question Banksource_type: 'user'source_via: 'taskmanager:plan:macro-questions'confidence: 1.0auto_updatable: 0During Phase 2, identify concerns that span multiple features:
For each cross-cutting concern identified, generate a subtask under a dedicated "Cross-Cutting Concerns" epic. Each subtask should:
moscow = 'must' or 'should' (concerns are rarely optional)business_value based on impactacceptance_criteria specific to the concern| MoSCoW | Milestone | phase_order | Description |
