/pbr:plan — Phase Planning

You are the orchestrator for /pbr:plan. This skill creates detailed, executable plans for a specific phase. Plans are the bridge between the roadmap and actual code — they must be specific enough for an executor agent to follow mechanically. Your job is to stay lean, delegate heavy work to agents, and keep the user's main context window clean.

Context Budget

Reference: skills/shared/context-budget.md for the universal orchestrator rules.

Additionally for this skill:

•Minimize reading agent output — read only plan frontmatter for summaries
•Delegate all research and planning work to agents — the orchestrator routes, it doesn't plan

Step 0 — Immediate Output

Before ANY tool calls, display this banner:

code

╔══════════════════════════════════════════════════════════════╗
║  PLAN-BUILD-RUN ► PLANNING PHASE {N}                         ║
╚══════════════════════════════════════════════════════════════╝

Where {N} is the phase number from $ARGUMENTS. Then proceed to Step 1.

Prerequisites

•.planning/config.json exists (run /pbr:begin first)
•.planning/ROADMAP.md exists with at least one phase
•.planning/REQUIREMENTS.md exists

Argument Parsing

Parse $ARGUMENTS according to skills/shared/phase-argument-parsing.md.

Standard Invocation

/pbr:plan <N> — Plan phase N

Parse the phase number and optional flags:

Argument	Meaning
`3`	Plan phase 3
`3 --skip-research`	Plan phase 3, skip research step
`3 --assumptions`	Surface assumptions before planning phase 3
`3 --gaps`	Create gap-closure plans for phase 3 (from VERIFICATION.md)
`3 --teams`	Plan phase 3 using specialist agent teams
(no number)	Use current phase from STATE.md

Subcommands

Subcommand	Meaning
`add`	Append a new phase to the end of the roadmap
`insert <N>`	Insert a new phase at position N (uses decimal numbering)
`remove <N>`	Remove phase N from the roadmap

Freeform Text Guard — CRITICAL

STOP. Before ANY context loading or Step 1 work, you MUST check whether $ARGUMENTS looks like freeform text rather than a valid invocation. This check is non-negotiable. Valid patterns are:

•Empty (no arguments)
•A phase number: integer (3, 03) or decimal (3.1)
•A subcommand: add, insert <N>, remove <N>
•A phase number followed by flags: 3 --skip-research, 3 --assumptions, 3 --gaps, 3 --teams
•The word check (legacy alias)

If $ARGUMENTS does NOT match any of these patterns — i.e., it contains freeform words that are not a recognized subcommand or flag — then stop execution and respond:

code

`/pbr:plan` expects a phase number or subcommand.

Usage:
  /pbr:plan <N>              Plan phase N
  /pbr:plan <N> --gaps       Create gap-closure plans
  /pbr:plan add              Add a new phase
  /pbr:plan insert <N>       Insert a phase at position N
  /pbr:plan remove <N>       Remove phase N

Then suggest the appropriate skill based on the text content:

If the text looks like...	Suggest
A task, idea, or feature request	`/pbr:todo` to capture it, or `/pbr:explore` to investigate
A bug or debugging request	`/pbr:debug` to investigate the issue
A review or quality concern	`/pbr:review` to assess existing work
Anything else	`/pbr:explore` for open-ended work

Do NOT proceed with planning. The user needs to use the correct skill.

Self-check: If you reach Step 1 without having matched a valid argument pattern above, you have a bug. Stop immediately and show the usage block.

Orchestration Flow: Standard Planning

Execute these steps in order for standard /pbr:plan <N> invocations.

Step 1: Parse and Validate (inline)

Reference: skills/shared/config-loading.md for the tooling shortcut (state load, plan-index, phase-info) and config field reference.

•Parse $ARGUMENTS for phase number and flags
•Read .planning/config.json for settings (see config-loading.md for field reference) CRITICAL: Write .active-skill NOW. Write the text "plan" to .planning/.active-skill using the Write tool.
•Resolve depth profile: run node ${PLUGIN_ROOT}/scripts/pbr-tools.js config resolve-depth to get the effective feature/gate settings for the current depth. Store the result for use in later gating decisions.
•
Validate:
- •Phase exists in ROADMAP.md
- •Phase directory exists at .planning/phases/{NN}-{slug}/
- •Phase does not already have PLAN.md files (unless user confirms re-planning)
•If no phase number given, read current phase from .planning/STATE.md
•CONTEXT.md existence check: If the phase is non-trivial (has 2+ requirements or success criteria), check whether a CONTEXT.md exists at EITHER .planning/CONTEXT.md (project-level) OR .planning/phases/{NN}-{slug}/CONTEXT.md (phase-level). If NEITHER exists, warn: "Phase {N} has no CONTEXT.md. Consider running /pbr:discuss {N} first to capture your preferences. Continue anyway?" If user says no, stop. If yes, continue. If at least one exists, proceed without warning.

If phase already has plans:

•
Use the yes-no pattern from skills/shared/gate-prompts.md: question: "Phase {N} already has plans. Re-plan from scratch?" header: "Re-plan?" options:
- •label: "Yes" description: "Delete existing plans and create new ones"
- •label: "No" description: "Keep existing plans unchanged"
•If "Yes": delete existing PLAN.md files in the phase directory
•If "No" or "Other": stop

Step 2: Load Context (inline)

Read context file PATHS and metadata. Build lean context bundles for agent prompts — include paths and one-line descriptions, NOT full file bodies. Agents have the Read tool and will pull file contents on-demand.

code

1. Read .planning/ROADMAP.md — extract current phase goal, dependencies, requirements
2. Read .planning/REQUIREMENTS.md — extract requirements mapped to this phase
3. Read .planning/CONTEXT.md (if exists) — extract only the `## Decision Summary` section (everything from `## Decision Summary` to the next `##` heading). If no Decision Summary section exists (legacy CONTEXT.md), fall back to extracting the full `## Decisions (LOCKED...)` and `## Deferred Ideas` sections.
4. Read .planning/phases/{NN}-{slug}/CONTEXT.md (if exists) — extract only the `## Decision Summary` section. Fall back to full locked decisions + deferred sections if no Decision Summary exists.
5. Read .planning/config.json — extract feature flags, depth, model settings
6. List prior SUMMARY.md file paths and extract frontmatter metadata only (status, provides, key_files). Do NOT read full SUMMARY bodies — agents pull these on-demand via Read tool.
7. Read .planning/research/SUMMARY.md (if exists) — extract research findings

Digest-select depth for prior SUMMARYs (Step 6):

Reference: skills/shared/digest-select.md for the full depth rules and examples. In short: direct dependencies get frontmatter + key decisions, transitive get frontmatter only, 2+ back get skipped.

Collect all of this into a context bundle that will be passed to agents.

Step 3: Assumption Surfacing (inline, if `--assumptions` flag)

IMPORTANT: This step is FREE (no agents). It happens entirely inline.

Before spawning any agents, present your assumptions about how this phase should be approached:

code

Phase {N}: {Name}
Goal: {from roadmap}

My assumptions about this phase:

1. **Approach**: I'm assuming we'll {approach}
   - Correct? [yes/no/adjust]

2. **Key technology**: I'm assuming we'll use {tech}
   - Correct? [yes/no/adjust]

3. **Architecture**: I'm assuming {architectural assumption}
   - Correct? [yes/no/adjust]

4. **Scope boundary**: I'm assuming {scope assumption}
   - Correct? [yes/no/adjust]

For each assumption the user corrects:

•Record the correction
•These corrections become additional CONTEXT.md entries

After all assumptions are confirmed/corrected:

•Update .planning/CONTEXT.md with any new locked decisions
•Continue to Step 4

Step 4: Phase Research (delegated, conditional)

Skip this step if ANY of these are true:

•--skip-research flag is set
•--gaps flag is set
•Depth profile has features.research_phase: false

To check: run node ${PLUGIN_ROOT}/scripts/pbr-tools.js config resolve-depth and read profile["features.research_phase"]. This replaces checking features.research_phase and depth separately -- the depth profile already incorporates both.

Conditional research (standard/balanced mode): When the profile has features.research_phase: true, also check whether .planning/codebase/ or .planning/research/ already contains relevant context for this phase. If substantial context exists (>3 files in codebase/ or a RESEARCH.md mentioning this phase's technologies), skip research and note: "Skipping research -- existing context found in {directory}." This implements the balanced mode's "conditional research" behavior.

If research is needed:

Display to the user: Spawning researcher...

Invoke the @researcher agent with the phase research prompt.

NOTE: The @researcher agent is defined in agents/researcher.md. Do NOT inline it.

Path resolution: Before constructing the agent prompt, resolve plugin root to its absolute path. Do not pass the variable literally in prompts. Use the resolved absolute path for any pbr-tools.js or template references included in the prompt.

Phase Research Prompt Template

Read skills/plan/templates/researcher-prompt.md.tmpl and use it as the prompt template for the researcher agent. Fill in the placeholders with phase-specific context:

•{NN} - phase number (zero-padded)
•{phase name} - phase name from roadmap
•{goal from roadmap} - phase goal statement
•{REQ-IDs mapped to this phase} - requirement IDs
•{dependencies from roadmap} - dependency list
•Fill <project_context> and <prior_work> blocks per the shared partial (templates/prompt-partials/phase-project-context.md.tmpl): Decision Summary for context, manifest table for prior work

Wait for the researcher to complete before proceeding.

Step 4.5: Seed Scanning (inline, before planning)

Before invoking the planner, scan .planning/seeds/ for seeds whose trigger matches the current phase:

•
Glob for .planning/seeds/*.md
•
For each seed file, read its frontmatter and check the trigger field
•
A seed matches if ANY of these are true:
- •trigger equals the phase slug (e.g., trigger: authentication) — preferred
- •trigger is a substring of the phase directory name (e.g., trigger: auth matches 03-authentication)
- •trigger equals the current phase number as integer (e.g., trigger: 3) — backward compatible but NOT recommended for new seeds (breaks with decimal phases like 3.1)
- •trigger equals * (always matches)
•
If matching seeds are found, present them to the user:
code
```
Found {N} seeds related to Phase {NN}:
  - {seed_name}: {seed description}
  - {seed_name}: {seed description}
```
Use the yes-no-pick pattern from skills/shared/gate-prompts.md: question: "Include these {N} seeds in planning?" header: "Seeds?" options: - label: "Yes, all" description: "Include all {N} matching seeds" - label: "Let me pick" description: "Choose which seeds to include" - label: "No" description: "Proceed without seeds"
•
If "Yes, all": include all matching seed content in the planner's context
•
If "Let me pick": present individual seeds for selection
•
If "No" or "Other": proceed without seeds
•
If no matching seeds found: proceed silently

Step 4.6: Surface Deferred Ideas (inline, before planning)

Before invoking the planner, check .planning/CONTEXT.md for deferred ideas that may be relevant to this phase:

•If .planning/CONTEXT.md does NOT exist, skip this step silently
•If it exists, scan for sections named "Deferred Ideas", "Deferred", "Ideas", or "Seeds" (case-insensitive heading match)
•For each deferred item found, check relevance to the current phase by comparing the item text against the phase goal, requirements, and slug
•
If relevant deferred items are found, present them to the user:
code
```
Found {N} deferred idea(s) from previous discussions that may be relevant to Phase {NN}:
  - {deferred item summary}
  - {deferred item summary}
```
Use the yes-no pattern from skills/shared/gate-prompts.md: question: "Include these deferred ideas in the planning context?" header: "Deferred Ideas" options: - label: "Yes" description: "Pass relevant deferred ideas to the planner" - label: "No" description: "Proceed without deferred ideas"
•If "Yes": append the relevant deferred items to the context bundle for the planner prompt (add them to the <project_context> block under a Deferred ideas to consider: heading)
•If "No" or no relevant items found: proceed without changes

This is a lightweight relevance filter — do NOT invoke an agent for this. Just match keywords from the deferred items against the phase goal and requirement text.

Step 5: Planning (delegated)

Team Mode (--teams)

Reference: references/agent-teams.md for team role definitions and coordination details.

If --teams flag is set OR config.parallelization.use_teams is true:

•
Create the team output directory: .planning/phases/{NN}-{slug}/team/
•
Display to the user: Spawning 3 planners in parallel (architect, security, test)...

Invoke THREE @planner agents in parallel:

Agent 1 -- Architect:
- •Invoke @planner with: "You are the ARCHITECT role in a planning team. Focus on: structure, file boundaries, dependency ordering, wave assignment. Write your output to .planning/phases/{NN}-{slug}/team/architect-PLAN.md. Do NOT write final PLAN.md files -- your output will be synthesized."
- •Include phase goal, research doc paths, CONTEXT.md path in the prompt
Agent 2 -- Security Reviewer:
- •Invoke @planner with: "You are the SECURITY REVIEWER role in a planning team. Focus on: authentication checks, input validation tasks, secrets handling, permission boundaries. Write your output to .planning/phases/{NN}-{slug}/team/security-PLAN.md. Do NOT write final PLAN.md files."
- •Include same context as Agent 1
Agent 3 -- Test Designer:
- •Invoke @planner with: "You are the TEST DESIGNER role in a planning team. Focus on: test strategy, coverage targets, edge cases, which tasks should use TDD, integration test boundaries. Write your output to .planning/phases/{NN}-{slug}/team/test-PLAN.md. Do NOT write final PLAN.md files."
- •Include same context as Agent 1
•
Wait for all three to complete
•
Display to the user: Spawning synthesizer...

Invoke @synthesizer with: "Read all files in .planning/phases/{NN}-{slug}/team/. Synthesize them into unified PLAN.md files in .planning/phases/{NN}-{slug}/. The architect output provides structure, the security output adds security-related tasks or checks, and the test output informs TDD flags and test tasks. Resolve any contradictions by preferring the architect's structure with security and test additions."
•
Proceed to plan checking as normal

If --teams is NOT set and config.parallelization.use_teams is false or unset, proceed with the existing single-planner flow below.

Single-Planner Flow (default)

Display to the user: Spawning planner...

Invoke the @planner agent with all context inlined.

NOTE: The @planner agent is defined in agents/planner.md. Do NOT inline it.

Planning Prompt Template

Read skills/plan/templates/planner-prompt.md.tmpl and use it as the prompt template for the planner agent. Fill in all placeholder blocks with phase-specific context:

•<phase_context> - phase number, directory, goal, requirements, dependencies, success criteria
•<project_context> - locked decisions, user constraints, deferred ideas, phase-specific decisions
•<prior_work> - manifest table of preceding phase SUMMARY.md file paths with status and one-line exports (NOT full bodies)
•<research> - file path to RESEARCH.md if it exists (NOT inlined content)
•<config> - max tasks, parallelization, TDD mode from config.json
•<planning_instructions> - phase-specific planning rules and output path

Wait for the planner to complete.

After the planner returns, read the plan files it created to extract counts. Display a completion summary:

code

Planner created {N} plan(s) across {M} wave(s)

Where {N} is the number of PLAN.md files written and {M} is the number of distinct wave values across those plans (from frontmatter).

Step 6: Plan Validation (delegated, conditional)

Skip this step if:

•Depth profile has features.plan_checking: false

To check: use the resolved depth profile from Step 1. The profile consolidates the depth setting and any user overrides into a single boolean.

If validation is enabled:

Display to the user: Spawning plan checker...

Invoke the @plan-checker agent with the checker prompt.

NOTE: The @plan-checker agent is defined in agents/plan-checker.md. Do NOT inline it.

Checker Prompt Template

Read skills/plan/templates/checker-prompt.md.tmpl and use it as the prompt template for the plan checker agent. Fill in the placeholders:

•<plans_to_check> - manifest table of PLAN.md file paths (checker reads each via Read tool)
•<phase_context> - phase goal and requirement IDs
•<context> - file paths to project-level and phase-level CONTEXT.md files (checker reads via Read tool)

Process checker results:

After the plan checker returns, display its result:

•If VERIFICATION PASSED: display Plan checker: all plans passed and proceed to Step 8
•If issues found: display Plan checker found {N} issue(s) — entering revision loop and proceed to Step 7

Step 7: Revision Loop (max 3 iterations)

Reference: skills/shared/revision-loop.md for the full Check-Revise-Escalate pattern.

Follow the revision loop pattern with:

•Producer: planner (re-invoked with skills/plan/templates/revision-prompt.md.tmpl)
•Checker: plan-checker (back to Step 6)
•Escalation: present issues to user, offer "Proceed anyway" or "Adjust approach" (re-enter Step 5)

Step 8: User Approval (inline, conditional)

Skip if:

•gates.confirm_plan is false in config
•mode is autonomous in config

If approval is needed:

Present a summary of all plans to the user:

code

Phase {N}: {name}
Plans: {count}

Plan {phase}-01: {plan name} (Wave {W}, {task_count} tasks)
  Must-haves: {list truths}
  Files: {list files_modified}
  Tasks:
    1. {task name}
    2. {task name}

Plan {phase}-02: {plan name} (Wave {W}, {task_count} tasks)
  ...

Wave execution order:
  Wave 1: Plan 01, Plan 02 (parallel)
  Wave 2: Plan 03 (depends on 01, 02)

Use the approve-revise-abort pattern from `skills/shared/gate-prompts.md`:
  question: "Approve these {count} plans for Phase {N}?"
  header: "Approve?"
  options:
    - label: "Approve"          description: "Proceed to build phase"
    - label: "Request changes"  description: "Discuss adjustments before proceeding"
    - label: "Abort"            description: "Cancel planning for this phase"

If user selects 'Request changes' or 'Other':

•Discuss what needs to change
•Re-enter Step 5 with updated context/constraints
•Or make small inline edits to plan files directly

If user selects 'Approve':

•
CONTEXT.md compliance reporting: If .planning/CONTEXT.md exists, compare all locked decisions against the generated plans. Print: "CONTEXT.md compliance: {M}/{N} locked decisions mapped to tasks" where M = locked decisions that are reflected in at least one task, N = total locked decisions. If any locked decisions are unmapped, list them as warnings.
•
Dependency fingerprinting: For each dependency phase (phases that this phase depends on, per ROADMAP.md):
1. •Find all SUMMARY.md files in the dependency phase directory
2. •Compute a simple hash of each SUMMARY.md file (e.g., first 8 chars of a SHA-256 of the file content, or a simpler approach: use the file's byte length + last-modified timestamp as a fingerprint string)
3. •
  Add a dependency_fingerprints field to each plan's YAML frontmatter:
  yaml
  dependency_fingerprints: "01-01": "len:4856-mod:2025-02-08T09:40" "01-02": "len:4375-mod:2025-02-08T09:43"
4. •This allows the build skill to detect if dependency phases were re-built after this plan was created
•
Update ROADMAP.md Progress table (REQUIRED — do this BEFORE updating STATE.md):

Tooling shortcut: Use the CLI for atomic updates:
bash
```
node ${PLUGIN_ROOT}/scripts/pbr-tools.js roadmap update-plans {phase} 0 {N}
node ${PLUGIN_ROOT}/scripts/pbr-tools.js roadmap update-status {phase} planned
node ${PLUGIN_ROOT}/scripts/pbr-tools.js state update status planned
node ${PLUGIN_ROOT}/scripts/pbr-tools.js state update last_activity now
```
1. •Open .planning/ROADMAP.md
2. •Find the ## Progress table
3. •Locate the row matching this phase number
4. •Update the Plans Complete column to 0/{N} where N = number of plan files just created
5. •Update the Status column to planned
6. •Save the file — do NOT skip this step
•
Update STATE.md (CRITICAL — update BOTH frontmatter AND body): set status: "planned", plans_total, last_command in frontmatter AND update Status:, Plan: lines in body ## Current Position
•
If features.auto_advance is true AND mode is autonomous: Chain directly to build. This continues the build->review->plan->build cycle automatically.
•
Otherwise: Suggest next action: /pbr:build {N}

Orchestration Flow: Subcommands

Subcommand: `add`

CRITICAL: Write .active-skill NOW. Write the text "plan" to .planning/.active-skill using the Write tool.

•Read .planning/ROADMAP.md
•Calculate next phase number (last phase + 1)
•Ask user: "What's the goal for this new phase?"
•Ask user: "What requirements does it address?" (show available unassigned REQ-IDs)
•Ask user: "What phases does it depend on?"
•Append phase to ROADMAP.md
•Create phase directory: .planning/phases/{NN}-{slug}/
•Update STATE.md if needed
•Suggest: /pbr:plan {N} to plan the new phase
•Delete .planning/.active-skill if it exists.

Subcommand: `insert <N>`

Reference: skills/plan/decimal-phase-calc.md for decimal numbering rules.

CRITICAL: Write .active-skill NOW. Write the text "plan" to .planning/.active-skill using the Write tool.

•Read .planning/ROADMAP.md
•
Calculate decimal phase number:
- •If inserting at position 3: becomes 3.1
- •If 3.1 already exists: becomes 3.2
- •Etc. (see decimal-phase-calc.md)
•Ask user for phase goal, requirements, dependencies
•Insert phase into ROADMAP.md at the correct position
•Create phase directory: .planning/phases/{NN.M}-{slug}/
•Update dependencies of subsequent phases if affected
•Suggest: /pbr:plan {N.M} to plan the new phase
•Delete .planning/.active-skill if it exists.

Subcommand: `remove <N>`

•Read .planning/ROADMAP.md
•
Validate:
- •Phase must exist
- •Phase must be in pending or not started status (cannot remove completed/in-progress phases)
- •No other phases depend on this phase (or user confirms breaking dependencies)
•CRITICAL: Write .active-skill NOW. Write the text "plan" to .planning/.active-skill using the Write tool.
•Confirm with user: "Remove Phase {N}: {name}? This will delete the phase directory and renumber subsequent phases."
•
If confirmed:
- •Delete .planning/phases/{NN}-{slug}/ directory
- •Remove phase from ROADMAP.md
- •Renumber subsequent phases (N+1 becomes N, etc.)
- •Update all depends_on references in ROADMAP.md
- •Update STATE.md if needed
•Delete .planning/.active-skill if it exists.

Orchestration Flow: Gap Closure (`--gaps`)

When invoked with --gaps:

•
Read .planning/phases/{NN}-{slug}/VERIFICATION.md
- •If no VERIFICATION.md exists: tell user "No verification report found. Run /pbr:review {N} first."
•Extract all gaps from the verification report
•Invoke @planner in Gap Closure mode:

Read skills/plan/templates/gap-closure-prompt.md.tmpl and use it as the prompt template for the gap closure planner. Fill in the placeholders:

•<verification_report> - inline the FULL VERIFICATION.md content
•<existing_plans> - inline all existing PLAN.md files for the phase
•<gap_closure_instructions> - specify output path and gap_closure frontmatter flag

•
After gap-closure plans are created:
- •Run plan checker (if enabled)
- •Present to user for approval
- •Suggest: /pbr:build {N} --gaps-only

Error Handling

Phase not found

If the specified phase doesn't exist in ROADMAP.md, display:

code

ERROR

Phase {N} not found in ROADMAP.md.

**To fix:** Run `/pbr:status` to see available phases.

Missing prerequisites

If REQUIREMENTS.md or ROADMAP.md don't exist, display:

code

ERROR

Project not initialized. Missing REQUIREMENTS.md or ROADMAP.md.

**To fix:** Run `/pbr:begin` first.

Research agent fails

If the researcher agent fails, display:

code

Research agent failed. Planning without phase-specific research.
This may result in less accurate plans.

Continue to the planning step.

Planner agent fails

If the planner agent fails, display:

code

ERROR

Planner agent failed for Phase {N}.

**To fix:**
- Try again with `/pbr:plan {N} --skip-research`
- Check `.planning/CONTEXT.md` for conflicting constraints

Checker loops forever

After 3 revision iterations without passing, display:

code

ERROR

Plan checker failed to pass after 3 revision iterations for Phase {N}.

**To fix:**
- Review the remaining issues below and decide whether to proceed or revise manually
- Run `/pbr:plan {N}` to restart planning from scratch

Present remaining issues and ask user to decide: proceed or intervene.

Files Created/Modified by /pbr:plan

File	Purpose	When
`.planning/phases/{NN}-{slug}/RESEARCH.md`	Phase-specific research	Step 4
`.planning/phases/{NN}-{slug}/PLAN-{NN}.md`	Executable plan files	Step 5
`.planning/CONTEXT.md`	Updated with assumptions	Step 3 (--assumptions)
`.planning/ROADMAP.md`	Plans Complete + Status -> `planned`; updated for add/insert/remove	Step 8, Subcommands
`.planning/STATE.md`	Updated with plan status	Step 8

Cleanup

Delete .planning/.active-skill if it exists. This must happen on all paths (success, partial, and failure) before reporting results.
