Universal Planner

Assets

This skill uses a modular assets architecture. Detailed documentation, templates, and helpers are in the assets/ directory:

• assets/modes/ — PLAN mode, EXECUTE mode, and 6 planning sub-modes

• assets/helpers/ — Config resolution, decision log, code quality, troubleshooting

• assets/templates/ — Document templates with frontmatter

• assets/validators/ — Output validation schemas

• assets/examples/ — Test cases and examples

See assets/README.md for full directory documentation.

Purpose

Unified planning and execution skill for any software engineering scenario. This skill operates in two mutually exclusive modes:

• PLAN mode — Produce professional, structured planning documentation. Detects the scenario (new project, feature, refactor, bug fix, tech debt, architecture) and activates the appropriate sub-mode. Never executes code.

• EXECUTE mode — Consume plan output and implement it sprint-by-sprint, phase-by-phase, task-by-task using dual roles (Senior Developer + Scrum Master). Never creates plans.

Critical Rules

RULE 1 — MODE BOUNDARY: PLAN NEVER EXECUTES, EXECUTE NEVER PLANS

PLAN mode produces documentation only — it MUST NOT implement, code, build, or deploy. EXECUTE mode implements existing plans only — it MUST NOT create new planning documents, modify strategy, or restructure sprints. This boundary is absolute.

RULE 2 — CONTEXT-FIRST: RESPECT EXISTING PATTERNS

Before making any decision on an existing codebase, explore and understand the project's established patterns, conventions, and architecture. Every proposal and implementation MUST align with what already exists. Deviations must be documented and justified.

RULE 3 — ADAPTIVE MODE DETECTION

Detect the top-level mode (PLAN vs EXECUTE) and planning sub-mode from the user's input. If ambiguous, ask. Never force a mode that doesn't match the scenario.

RULE 4 — PROFESSIONAL QUALITY

In PLAN mode: output must read as if produced by a senior engineering team — no vague language, no placeholders. In EXECUTE mode: write production-quality code — clean, readable, properly tested.

RULE 5 — COMPLETENESS

PLAN mode: generate ALL documents required by the active sub-mode. EXECUTE mode: complete ALL tasks in a phase before moving to the next.

RULE 6 — PLAN IS SOURCE OF TRUTH (EXECUTE MODE)

The planning documents define what to build, how to structure it, and which patterns to follow. Every implementation decision must trace back to the plan. Do not improvise architecture or invent new patterns.

RULE 7 — CONVENTIONS ARE NON-NEGOTIABLE

discovery/CONVENTIONS.md defines the project's DNA. Every planning proposal and every line of implementation code MUST follow these conventions.

RULE 8 — ASSUMPTION TRANSPARENCY

When information is missing: PLAN mode documents assumptions in ANALYSIS.md. EXECUTE mode documents decisions in the Decision Log. Never silently assume.

Mode Detection

Top-Level: PLAN vs EXECUTE

Mode Signals Example Inputs

PLAN Planning, analyzing, designing, "plan", "create a plan", new work without existing plan "Plan the auth system", "I need an app to track expenses"

EXECUTE Implementing, executing, "start working", "implement the plan", existing plan output present "Execute the project plan", "Start implementing Sprint 1"

Disambiguation: If the user's intent is unclear, ask:

"Do you want me to plan this work (produce documentation) or execute an existing plan (implement code)?"

PLAN Sub-Modes

When in PLAN mode, detect the planning sub-mode. See assets/modes/PLAN.md for the full detection table and capabilities matrix.

Sub-Mode Signals

NEW_PROJECT Product idea, "build from scratch", no existing codebase

NEW_FEATURE Adding to existing project, "add", "implement"

REFACTOR Restructure, reorganize, migrate patterns

BUG_FIX Fix, broken, regression, error

TECH_DEBT Cleanup, dead code, deprecated, missing tests

ARCHITECTURE System design, scaling, infrastructure change

Asset Loading (Mode-Gated)

After detecting the mode, read ONLY the assets listed for that mode. Do NOT read assets for other modes — they waste context tokens.

Mode Read These Assets Do NOT Read

PLAN output-resolve.md , PLAN.md , detected sub-mode .md

EXECUTE.md, config-resolver.md, decision-log.md, code-quality-standards.md, unrelated sub-mode files, examples/, validators/

EXECUTE output-resolve.md , EXECUTE.md , decision-log.md , code-quality-standards.md

PLAN.md, config-resolver.md, all sub-mode files, templates/, examples/, validators/

PLAN sub-mode loading: After detecting the sub-mode from user input, read ONLY that file (e.g., NEW_FEATURE.md ). Do NOT read the other 5 sub-mode files. Templates are loaded on-demand as each workflow step references them.

On-demand helpers (both modes): troubleshooting.md — read only when issues arise. config-resolver.md — loaded only when output-resolve.md can't find existing config (first-time setup).

Quick Start

PLAN Mode

Use when planning any software work:

Plan the authentication system for the app.

Assets to read now: output-resolve.md + PLAN.md — then read only the detected sub-mode file from assets/modes/.

EXECUTE Mode

Use when implementing an existing plan:

Execute the project plan.

Assets to read now: output-resolve.md + EXECUTE.md + decision-log.md + code-quality-standards.md

Mode Workflows (Quick Reference)

PLAN Mode Workflow

• Configuration Resolution → resolve {output_dir}

• Codebase Discovery → discovery/CONVENTIONS.md (except NEW_PROJECT)

• Analysis → analysis/ANALYSIS.md

• Planning → planning/PLANNING.md

• Execution Plan → execution/EXECUTION.md

• Sprint Plans (optional) → sprints/PROGRESS.md

• sprints/SPRINT-*.md

• Handoff → summarize and stop

Full details: See assets/modes/PLAN.md

EXECUTE Mode Workflow

• Locate and Validate → verify plan directory exists and is complete

• Internalize Plan → read all planning documents

• Execute Active Sprint → phase-by-phase, task-by-task

• Complete Sprint → update tracking, verify graduation gates 3.5. Retrospective (optional) → capture learnings

• Project Completion → final metrics and report

Full details: See assets/modes/EXECUTE.md

Configuration Resolution

{output_dir} is the directory where universal-planner stores all planning documents. Resolve it once at the start:

• User message context — If the user's message contains file paths, extract {output_dir} from those paths

• Auto-discover — Scan for .agents/universal-planner/ in {cwd}

• Ask the user — If nothing found, ask where to save documents. Default suggestion: .agents/universal-planner/{project-name}/

No AGENTS.md. No branded blocks. The output directory is resolved at runtime.

See assets/helpers/output-resolve.md for the lightweight resolver. For full error handling, see assets/helpers/config-resolver.md.

Obsidian Output Standard

All documents generated or modified by this skill MUST follow these rules:

• Frontmatter: Every .md file includes the universal frontmatter schema (title, date, updated, project, type, status, version, tags, changelog, related)

• Types: Use conventions , analysis , plan , execution-plan , sprint-plan , progress , requirements , architecture , retrospective as appropriate

• Wiki-links: All inter-document references use [[filename]] syntax — never text

• References: Every document ends with ## References listing Parent, Siblings, Children, and Input Documents

• Living documents: PROGRESS.md and sprint plans are living documents — bump version , update changelog , transition status on modification

• IDs: Use FR-/NFR- for requirements, ADR- for architecture decisions, T- for tasks, DEC- for decisions, K-/P-/L-/A- for retrospective items

• Bidirectional: If document A references B, document B must reference A in related and ## Referencias

• Metrics: Use | Metric | Before | After | Delta | Status | format for all quantitative data

• Gates: Sprint plans include ## Graduation Gate with verifiable checkbox criteria

• Carried Forward: Sprint 2+ includes ## Carried Forward from [[previous-sprint]] for incomplete items

• Sequential numbering: Use 01- , 02- prefixes where reading order matters

• Status transitions: Move status through draft → active → completed (or draft → active → failed ) as work progresses

Frontmatter template for sprint plans:

title: "Sprint {N}: {Name}" date: "YYYY-MM-DD" updated: "YYYY-MM-DD" project: "{project-name}" type: "sprint-plan" status: "draft" version: "1.0" sprint: {N} phase: "{active-phases}" progress: 0 previous_doc: "[[SPRINT-{N-1}-name]]" next_doc: "[[SPRINT-{N+1}-name]]" parent_doc: "[[PROGRESS]]" tags: ["{project-name}", "sprint-{N}", "sprint-plan"] changelog:

• version: "1.0" date: "YYYY-MM-DD" changes: ["Initial sprint plan"] related:
• "[[PROGRESS]]"
• "[[EXECUTION]]"
• "[[SPRINT-{N-1}-name]]"
• "[[SPRINT-{N+1}-name]]"

Mode-specific frontmatter extensions:

• BUG_FIX: Add severity: "critical|high|medium|low" to ANALYSIS.md frontmatter

• REFACTOR: Add scope_modules: ["module-a", "module-b"] to ANALYSIS.md frontmatter

Sprint Structure Standards

All sprint documents follow the Obsidian-native markdown standard with structured frontmatter, progress tracking, and cross-references.

Complete sprint formats: See assets/templates/SPRINT.md

Task granularity:

• L1 - Sprint: Major milestone (3-7 days)

• L2 - Phase: Logical grouping (0.5-2 days)

• L3 - Task: Discrete work item (1-4 hours) with file paths, before/after code, verification

• L4 - Subtask: Single action (5-30 min)

Every task must include: checkbox, file paths (when applicable), before/after code snippets, verification command, and reference to existing patterns/components.

Troubleshooting

Common issues and resolutions for both PLAN and EXECUTE modes.

Full troubleshooting guide: See assets/helpers/troubleshooting.md

Limitations

• Mode boundary: PLAN mode cannot execute; EXECUTE mode cannot plan

• Requires input: PLAN mode needs a description of the work; EXECUTE mode needs plan output

• Assumptions must be validated: Inferred decisions need team review before implementation

• Technology recommendations are suggestions: The development team makes final choices

• Manual tracking: Sprint progress must be updated manually during execution

• No automated validation: Cannot verify plans match codebase reality — relies on thorough discovery

• Sequential execution: EXECUTE mode processes one sprint at a time, in order

• External blockers: Cannot resolve dependencies on external teams or services — logs them and moves on

• Context window: For projects with more than 4 sprints, consider executing sprints in separate sessions to avoid context exhaustion. EXECUTE mode can resume from the last incomplete sprint.
