Planning
Create detailed technical implementation plans through research, codebase analysis, solution design, and comprehensive documentation.
Prerequisites
AgentKit CLI required: This skill requires the ak CLI for plan operations.
Install AgentKit before using CLI-managed plan scaffolding or status updates.
CLI Integration
This skill orchestrates planning, but AgentKit CLI owns plan file scaffolding and phase state mutations whenever ak is available.
Use these commands instead of hand-editing CLI-managed plan structure:
ak plan create "{plan title}" --basedir /absolute/path/to/plans
ak plan add-phase /absolute/path/to/plan-dir "Implement"
ak plan add-phase /absolute/path/to/plan-dir "Test"
ak plan check /absolute/path/to/plan-dir/phase-01-start.md
ak plan uncheck /absolute/path/to/plan-dir/phase-01-start.md
ak plan status /absolute/path/to/plan-dir
ak config start --port 3456 --no-open
Rules:
Use ak plan create to scaffold plan.md and the starter phase-*.md when the CLI is available.
When --html is present, the final user-facing plan artifact is plan.html.
Use ak plan create only when a plan directory, active-plan metadata, or a
--github companion plan.md index is needed. Do not duplicate the full plan
body across Markdown and HTML.
Default scope is project-local (./plans/ under the current project).
Global scope is conditional: use the configured global plans root only when the user asks for global planning or no project context exists.
Use ak plan check / ak plan uncheck for phase status changes.
Do not hand-edit the phases table for status toggles or structural updates when CLI commands are available.
Use the dashboard at http://localhost:3456/plans for visual plan management.
Generated-file write guard:ak plan create and ak plan add-phase create existing plan.md and phase-XX-*.md stub files. Before composing long replacement content, run a read pass over plan.md and every generated phase stub. A directory listing is not enough. Claude Code enforces Read-before-Write on existing files; skipping any stub read causes that file's Write to be rejected after wasting the full Write payload. The stubs are tiny, so read them all first, then fill them.
Mandatory Generated-File Read Pass
After ak plan create and before the first long Write/Edit to any generated plan file:
Enumerate generated files: plan.md plus all phase-*.md.
Read plan.md.
Read every generated phase-*.md stub, including future phases you have not drafted yet.
Only after the read pass, write or edit the full content for plan.md and each phase.
Do not draft or submit a full phase body for a generated stub that has not been read in the current session.
Canonical Phase File Template
Use this structure when filling each phase-XX-*.md. Loaded once with the skill — no per-file Read needed to learn it. Frontmatter fields match the CLI's phase schema; section headers match documentation-management.md so phase files stay consistent across plans.
IMPORTANT: Before you start, scan unfinished plans in the active scope first:
Project scope: ./plans/
Global scope: the configured global plans root
Default when unset: ~/.claude/plans/
If there are relevant plans overlapping your upcoming plan, update them as well. If you're unsure or need more clarifications, use ask_user capability tool to ask the user.
Scope Selection
Project scope is the default whenever the current working tree has project context.
Global scope is allowed only when:
the user explicitly asks for it via --global, or
there is no project context to anchor a local plan.
No project context means no .git, package.json, or CLAUDE.md was found in the ancestor chain.
Keep scope honest in prose and examples: the skill describes CLI-owned behavior, it does not implement scope resolution itself.
Cross-Plan Dependency Detection
During the pre-creation scan, detect and mark blocking relationships between plans:
Scan — Read plan.md frontmatter of each unfinished plan (status != completed/cancelled)
Compare scope — Check overlapping files, shared dependencies, same feature area
Classify relationship:
New plan needs output of existing plan → new plan blockedBy: [existing-plan-dir]
New plan changes something existing plan depends on → existing plan blockedBy: [new-plan-dir], new plan blocks: [existing-plan-dir]
Cross-scope dependency → use global: or project: prefixes
Mutual dependency → both plans reference each other in blockedBy/blocks
Bidirectional update — When relationship detected, update BOTH plan.md files' frontmatter
Ambiguous? → Use ask_user capability with header "Plan Dependency", present detected overlap, ask user to confirm relationship type (blocks/blockedBy/none)
Status interaction:ak plan status is the authoritative inspection surface. Same-scope bare refs stay in the current scope; prefixed refs resolve against the explicit project/global root. Missing refs should warn and show not found, not hard-fail the plan.
Default (No Arguments)
If invoked with a task description, proceed with planning workflow. If invoked WITHOUT arguments or with unclear intent, use ask_user capability to present available operations:

--html

--github
Create or update a GitHub issue after plan validation with branch, summary, plan links, open questions, and ready to review
--wiki
Publish the final reviewed plan docs or HTML artifact to AgentWiki via CLI or MCP when available
HTML Output Mode (--html)
When --html is present, activate /ak:frontend-design before composing the
HTML artifact. If ak:frontend-design requires design intelligence, follow its
ak:ui-ux-pro-max activation rule before styling.
Artifact rules:
Write the primary output as plan.html in the selected plan directory.
The HTML file must be self-contained: inline CSS and JavaScript, no build
step, no network-required assets.
If generated image assets are used, embed selected images as data URIs so
plan.html remains portable; keep source images under {plan-dir}/assets/
for review only.
Generate plan.html after red-team and validation gates so the HTML reflects
the final reviewed plan. Markdown files produced for CLI scaffolding or gate
compatibility are not the user-facing deliverable in this mode.
If another workflow requires plan.md (for example --github), keep
plan.md as a concise index that points to plan.html; do not duplicate the
full plan body unless a downstream /ak:cook handoff explicitly needs it.
Include accessible responsive UI, keyboard-friendly controls, and reduced
motion handling.
Content requirements:
Plan overview and phase roadmap.
Main page must show a concise outline summary for every phase: title, status,
priority, dependencies, objective, 3-6 key bullets, related files,
success criteria highlights, and test/validation gate when known.
Each phase outline must open a detail modal rendering the full phase markdown:
headings, lists, checkboxes, tables, fenced code, inline code, blockquotes,
links, horizontal rules, and frontmatter metadata. Escape raw HTML unless a
trusted sanitizer is bundled inline.
User flows.
Diagrams and charts rendered directly in HTML/CSS/SVG/Canvas.
Interactive affordances such as tabs, filters, expandable risks, or chart
toggles when useful.
Citations as visible URLs for external sources, GitHub issues, docs, and
any web references used.
Open questions section; write "None" when there are no unresolved questions.
Generated illustration requirements:
If imagegen, built-in image_gen, or create_image is available, generate
1-3 raster illustrations for the HTML.
Prompt style: technical sketch, watercolor wash, hand-drawn engineering
notebook, ink linework, warm paper, muted red/gold accents, no text, no logo,
no watermark.
If image generation is unavailable or fails, continue with typographic
diagrams / CSS-only structure and state the limitation in the final response.
Design direction:
Use the editorial magazine style contract from the user's supplied guideline
when present; otherwise use this built-in contract.
Use warm paper #faf7f2, paper panels #f0ebe1, ink #0a0a0a, muted
#6b6258, accent red #b8232c, hairline dividers, serif display, mono
labels, and restrained sans body.
Use print-editorial structure: cover section, running mono slide tags/folios,
generous whitespace, asymmetric grids, rule lines, pull quotes, stat bands,
and fixed nav dots when useful.
Avoid gradients, drop shadows, rounded cards, pure white backgrounds, generic
SaaS styling, decorative bokeh/orbs, emoji icons, and hidden instructions.
Use accent only for italic serif emphasis, eyebrows, active states, left
rules, and small data highlights. Include subtle CSS paper grain.
Keep typography readable on mobile and desktop; no horizontal scrolling.
GitHub Issue Mode (--github)
When --github is present, create or update a GitHub issue after validation and
red-team gates finish and before implementation handoff.
Required issue fields:
Branch name from git branch --show-current.
Plan summary.
Repo-relative link to plan.md.
Repo-relative link to plan.html when --html is present.
Repo-relative link to the brainstorm report when one exists; otherwise state
Brainstorm report: None found.
Open questions when present; otherwise state Open questions: None.
Acceptance criteria from the validated plan.
Required label:ready to review.
AK lifecycle labels (ready to cook, in progress, ready to ship *) are
owned by ak-vibe/ak-issue-to-plan; ready to review marks a
plan-awaiting-human-review stage before ready to cook.
Issue creation rules:
gh label list --json name --jq '.[].name' | grep -Fx "ready to review" >/dev/null \
|| gh label create "ready to review" --color "C5DEF5" --description "Plan ready for human review"
gh issue create --title "<plan title>" --body-file "<body.md>" --label "ready to review"
If an issue already exists for the same plan or branch, update/comment on it
instead of creating a duplicate.
All links posted to GitHub must be repo-relative. Do not post absolute local
filesystem paths.
Redact secrets, env values, tokens, customer data, private logs, and local
machine-specific details before writing issue bodies or comments.
If gh cannot create labels or issues, stop and report the exact error.
Combined --html --github
plan.html is the authoritative plan. Create a short companion plan.md index
only to satisfy the GitHub issue's stable plan.md link requirement. The issue
must include both relative links.
AgentWiki Publish Mode (--wiki)
When --wiki is present, publish the final reviewed plan artifact to AgentWiki
after validation/red-team gates and after plan.html generation when --html
is also present.
Deliberate AK divergence from upstream publish-first default (issue #685):
--wiki is private/workspace-first. Use agentwiki doc share by default.
Run agentwiki doc publish or agentwiki sites upload only when the user
explicitly requests public publishing or a public hosted site.
Availability check:
Prefer AgentWiki CLI when command -v agentwiki succeeds and
agentwiki whoami confirms auth.
If CLI is unavailable, use AgentWiki MCP tools when exposed in the session
for document create/update, file upload, share links, or static site upload.
If neither is available or auth fails, do not block plan creation. Report
"AgentWiki publish skipped" with the exact missing capability.
Markdown/document publish:
Publish a reviewed Markdown artifact. If the plan spans phase-*.md files,
create {plan-dir}/wiki-publish.md as a concise combined document or index
before uploading.
Capture the returned share URL and include it in the final response. Use
agentwiki doc publish "{document-id}" --description "{short summary}" --json
only on explicit user request for a public document.
HTML/static-site publish:
For --html, keep the self-contained plan.html local by default and report
its path. Upload it as a public hosted site only when the user explicitly asks:
Capture the returned site URL and include it in the final response. If
--github is also present, comment on or update the issue with the wiki URL.
MCP fallback:
Use AgentWiki MCP document tools for Markdown content when available
(document_create/document_update, upload, share-link equivalents).
Use MCP static-site upload only if the active toolset exposes that exact
capability and the user explicitly requested public site upload. Do not fake
a hosted URL from a raw file upload.
Security rules:
Redact secrets, env values, tokens, customer data, private logs, and
local-machine-only paths before publishing.
Prefer repo-relative paths and public-safe summaries.
Publish only final reviewed artifacts; do not publish intermediate research
notes unless the user explicitly asks.

This diagram is the authoritative workflow. Prose sections below provide detail for each node.
Workflow Process
Pre-Creation Check → Check Plan Context for active/suggested/none
1b. Cross-Plan Scan → Scan unfinished plans, detect blockedBy/blocks relationships, update both plans
1c. Scope Challenge → Run Step 0 scope questions, select mode (see references/scope-challenge.md)
Skip if:--fast mode or trivial task
Mode Detection → Auto-detect or use explicit flag (see workflow-modes.md)
Research Phase → Spawn researchers (skip in fast mode)
Codebase Analysis → Read docs, scout if needed
Plan Documentation → Write comprehensive plan via planner subagent
Red Team Review → Run /ak:plan red-team {plan-path} (hard/deep/parallel/two modes)
Post-Plan Validation → Run /ak:plan validate {plan-path} (hard/deep/parallel/two modes)
HTML Artifact → If --html, activate /ak:frontend-design and write final reviewed plan.html as the primary output
Hydrate Tasks → Create Claude Tasks from phases (default on, --no-tasks to skip)
GitHub Issue → If --github, create/update issue and apply ready to review
AgentWiki Publish → If --wiki, publish final docs privately or upload plan.html only when AgentWiki CLI/MCP is available and the requested visibility permits it
Boundary Reminder → Present optional next-step commands with absolute path
Journal → Run /ak:journal to write a concise technical journal entry upon completion
Whole-Plan Consistency Gate
This gate is mandatory after /ak:plan validate or /ak:plan red-team edits any plan file.
Load: references/verification-roles.md → "Whole-Plan Consistency Sweep".
Before recommending /ak:cook, re-read plan.md and every phase-*.md file. Search all plan files for stale terms, rejected assumptions, renamed APIs/files/fields, superseded decisions, and duplicate embedded drafts/contracts. Reconcile contradictions across the entire plan, not only the edited phase.
If unresolved contradictions remain, report them and ask the user. Do not recommend cook until the whole-plan consistency sweep reports zero unresolved contradictions.
Output Requirements
IMPORTANT: Invoke "/ak:project-organization" skill to organize the outputs.
DO NOT implement code - only create plans
Respond with plan file path and summary
Ensure self-contained plans with necessary context
Include code snippets/pseudocode when clarifying
With --html, respond with the plan.html path, the companion plan.md
index path when one exists, and a short note that HTML is authoritative.
With --github, respond with the GitHub issue URL and confirm the
ready to review label was applied.
With --wiki, respond with the AgentWiki document/share/site URL when
published, or state the exact reason publishing was skipped.
Fully respect the ./docs/development-rules.md file
Task Management
Plan files = persistent. Tasks = session-scoped. Hydration bridges the gap.
Default: Auto-hydrate tasks after plan files are written. Skip with --no-tasks.
3-Task Rule: <3 phases → skip task creation.
Fallback: Task tools (manage_plan capability/manage_plan capability/manage_plan capability/manage_plan capability) are CLI-only — unavailable in VSCode extension. If they error, use manage_plan capability for tracking. Plan files remain the source of truth; hydration is an optimization, not a requirement.
Cook picks up via manage_plan capability (same session) or re-hydrates (new session)
Active Plan State
Check ## Plan Context injected by hooks:
"Plan: {path}" → Active plan. Ask "Continue? [Y/n]"
"Suggested: {path}" → Branch hint only. Ask if activate or create new.
"Plan: none" → Create new using Plan dir: from ## Naming
After creating plan: node .agentkit/scripts/set-active-plan.cjs {plan-dir}
Reports: Active plans → plan-specific path. Suggested → default path.
Important
DO NOT create plans or reports in arbitrary user directories.
MUST create plans or reports in one of these allowed roots:
project scope → current working project directory
global scope → configured global plans root
Default when unset: ~/.claude/plans/
Subcommands

Validate plan with critical questions interview
Post-Plan Handoff (MANDATORY at session end)
After plan.md + phase files are written and the user has reviewed/approved them, use ask_user capability to offer the appropriate next step. Recommend the option that best fits the plan's risk/scope; recommended option listed FIRST and labelled "(Recommended)".
Option
Recommend When
Why
/ak:plan validate
Plan is moderate-to-complex; user wants critical-questions interview before implementation
Plan touches security, auth, payments, data integrity, public APIs, infra, or has high blast radius
Adversarial reviewers stress-test the plan for failure modes, attack vectors, and missing edge cases
/ak:cook <plan-path>
Plan is small / well-understood / low-risk and user wants to start implementation
Skip extra gates; go straight to implementation
End session
User wants to review/share plan before deciding
Stop with plan path returned
Skip this step ONLY when:
The current invocation IS already a subcommand (validate, red-team, archive) — those have their own terminal handoff.
User explicitly said "just plan, don't suggest next step".
Skip an individual option ONLY when the active mode already auto-ran that gate (per Workflow Process Steps 6-7):
Omit /ak:plan red-team from the offered options when mode is --hard, --deep, --parallel, or --two (Step 6 already ran adversarial review).
Omit /ak:plan validate from the offered options when mode is --deep (Step 7 already ran validation).
If both gates already ran, the Post-Plan Handoff still fires but offers only /ak:cook <plan-path> and End session.
After selection: invoke the chosen command with the plan path as argument for continuity.
Quality Standards
Thorough and specific, consider long-term maintainability
Research thoroughly when uncertain
Address security and performance concerns
Detailed enough for junior developers
Validate against existing codebase patterns
Remember: Plan quality determines implementation success. Be comprehensive and consider all solution aspects.
Workflow Position
Typically follows:/ak:brainstorm (after exploring options), /ak:scout (after codebase discovery)
May precede:/ak:cook after user approval (otherwise stop with plan path and next-step options)
Related:/ak:brainstorm (explore before planning), /ak:cook (execute after planning)
