What it does

Project Architect is an agent skill from ersinkoc/project-architect. Documentation-first project planning that produces implementation-ready blueprints and single-shot coding agent prompts. Generates 4 interconnected docs — SPECIFICATION.md, IMPLEMENTATION.md, TASKS.md, BRANDING.md — plus a self-contained PROMPT.md for autonomous execution by any coding agent. Includes interactive tech stack selection, design pattern recommendations, and architecture decisions with trade-off analysis. Trigger when user wants to: plan a project, create specs, architect a system, break work into…

Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including reference files (for example `README.md`, `plugin.json` and `references/agent-prompt.md`). Compatibility notes: Works with any coding agent that supports file read/write and user interaction. Optimized for WrongStack and Claude Code, also compatible with Cursor, Gemini…

It sits in Development, covering Project management and Design patterns. The repository describes itself as: Documentation-first project planning agent skill. Generates specs, implementation plans, tasks, and single-shot prompts for coding agents. Compatible with Claude Code, Cursor… The licence is MIT.

When your agent uses it

  • User wants to: plan a project
  • Architect a system
  • Break work into tasks
  • Choose a tech stack

Example prompts

  • “plan my project”
  • “spec this out”
  • “architect”
  • “/project-architect”

Requirements

  • Compatibility (from SKILL.md): Works with any coding agent that supports file read/write and user interaction. Optimized for WrongStack and Claude Code, also compatible with Cursor, Gemini CLI, Codex, and other agentskills.io-compatible agents.

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Discovery & Elicitation
  2. SPECIFICATION.md
  3. IMPLEMENTATION.md
  4. TASKS.md
  5. BRANDING.md (Optional)
  6. PROMPT.md (Always Generate)

What it can do on your machine

Read from SKILL.md and the folder at commit 220653c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Works with any coding agent that supports file read/write and user interaction. Optimized for WrongStack and Claude Code, also compatible with Cursor, Gemini CLI, Codex, and other agentskills.io-compatible agents.

    From compatibility in the SKILL.md frontmatter.

Context cost

Project Architect loads about 2.3k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 211 tokens; SKILL.md has 840 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~211
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~21k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Project Architect

A documentation-first project planning system that produces implementation-ready blueprints and agent-ready prompts. The philosophy: think deeply, document thoroughly, then execute with zero ambiguity. The final PROMPT.md is self-contained and portable — hand it to WrongStack, Claude Code, or any agent that reads and writes files.

Output Pipeline

[Discovery]  →  SPECIFICATION.md  →  IMPLEMENTATION.md  →  TASKS.md  →  BRANDING.md
                  (The What)           (The How)           (The Work)    (Identity)
                       ↓                    ↓                   ↓
                       └────────────────────┴───────────────────┘
                                          ↓
                                     PROMPT.md
                             (Single-Shot Agent Prompt)

Each document feeds the next. The final PROMPT.md synthesizes all documents into a single prompt optimized for single-shot execution by any coding agent (WrongStack, Claude Code, Cursor, and others).

Reference Files

Read the appropriate reference file before generating each document:

PhaseReference FileWhen to Read
Discovery${CLAUDE_PLUGIN_ROOT}/references/elicitation-guide.mdBefore asking any questions
Tech Stack${CLAUDE_PLUGIN_ROOT}/references/tech-stacks.mdWhen user needs stack selection help
Patterns${CLAUDE_PLUGIN_ROOT}/references/design-patterns.mdWhen making architecture decisions
Specification${CLAUDE_PLUGIN_ROOT}/references/specification-guide.mdBefore generating SPECIFICATION.md
Implementation${CLAUDE_PLUGIN_ROOT}/references/implementation-guide.mdBefore generating IMPLEMENTATION.md
Tasks${CLAUDE_PLUGIN_ROOT}/references/tasks-guide.mdBefore generating TASKS.md
Branding${CLAUDE_PLUGIN_ROOT}/references/branding-guide.mdBefore generating BRANDING.md
Prompt${CLAUDE_PLUGIN_ROOT}/references/agent-prompt.mdBefore generating PROMPT.md

Workflow

Phase 0: Discovery & Elicitation

Read ${CLAUDE_PLUGIN_ROOT}/references/elicitation-guide.md for the full question framework.

Before writing anything, understand the project through structured conversation. Use AskUserQuestion tool aggressively for choices — the user should tap, not type, whenever possible.

Minimum understanding before any document generation:

  1. What does this project do? (elevator pitch)
  2. Who is it for? (target audience)
  3. What's the project type? (web app, CLI, library, API, mobile, desktop, infra tool)
  4. What's the scope? (MVP vs full product)
  5. Tech stack direction (or "help me choose")

If the user says "help me choose a stack": Read ${CLAUDE_PLUGIN_ROOT}/references/tech-stacks.md and run the interactive stack selection flow. Present options with trade-offs using AskUserQuestion.

Phase 1: SPECIFICATION.md

Read ${CLAUDE_PLUGIN_ROOT}/references/specification-guide.md before generating.

Defines what the project is. Technology-aware but not implementation-detailed. After generating, pause for user review.

Phase 2: IMPLEMENTATION.md

Read ${CLAUDE_PLUGIN_ROOT}/references/implementation-guide.md AND ${CLAUDE_PLUGIN_ROOT}/references/design-patterns.md before generating.

Translates specification into how to build it. This is where you:

  • Recommend design patterns based on the project's needs (consult patterns reference)
  • Define concrete directory structures with file-by-file purpose
  • Choose dependencies with rationale
  • Define module interfaces and data flows
  • Include code snippets for critical patterns (signatures, types, structural examples)

Pattern Recommendations: Consult ${CLAUDE_PLUGIN_ROOT}/references/design-patterns.md and recommend specific patterns with rationale. Don't just name-drop — show how each pattern applies to THIS project with a short code sketch.

Phase 3: TASKS.md

Read ${CLAUDE_PLUGIN_ROOT}/references/tasks-guide.md before generating.

Converts implementation into ordered work items. Each task must be:

  • Completable by a coding agent in a single session
  • Self-contained with full context
  • Ordered by strict dependency chain
  • Include the exact files to create/modify
Phase 4: BRANDING.md (Optional)

Read ${CLAUDE_PLUGIN_ROOT}/references/branding-guide.md before generating.

Only generate if user wants it or the project is user-facing.

Phase 5: PROMPT.md (Always Generate)

Read ${CLAUDE_PLUGIN_ROOT}/references/agent-prompt.md before generating.

This is the most critical output. Synthesize all documents into a single-shot prompt that any coding agent (WrongStack, Claude Code, Cursor, …) can execute to build the entire project from scratch. The prompt must be completely self-contained, with inline code for complex patterns and an ordered checklist of every file to create.

Operating Rules

  1. Document order is sequential. SPEC → IMPL → TASKS → BRANDING → PROMPT. Never skip ahead.

  2. Pause between documents. Present each doc, ask for approval before the next.

  3. Use AskUserQuestion for decisions. Tech stack, database, auth, deployment — any decision with 2-4 clear options should use interactive selection, not freeform questions.

  4. Recommend, don't dictate. Present 2-3 options with trade-offs. Let user choose. If user says "you pick", choose and explain why.

  5. Scale to project size. Weekend project = concise docs, 15-30 tasks. Enterprise platform = thorough docs, 100+ tasks. Match depth to ambition.

  6. Always save as files. Every document goes to ./[project-name]/docs/ in the current working directory as Markdown files. Use the Write tool to save them.

  7. Cross-reference between documents. IMPL references SPEC sections. TASKS reference IMPL modules. PROMPT inlines everything needed.

  8. No filler. Every line must be specific to THIS project. Remove sections that would be generic boilerplate.

  9. Design patterns are recommendations. When choosing patterns for IMPLEMENTATION.md, consult ${CLAUDE_PLUGIN_ROOT}/references/design-patterns.md and match patterns to the project's specific needs. Include a brief "why this pattern" rationale for each recommendation.

Plugin-Aware Integration

Check if the user has other Claude Code plugins or skills installed. If they do:

  • Frontend framework planner (react-app-planner, nextjs-app-planner, etc.) → Suggest using it for deeper framework decisions after architect docs are done
  • Frontend design → Reference it for UI component guidance in IMPLEMENTATION.md
  • Brand/design skills → Integrate into BRANDING.md generation
  • MCP builder → If project includes an MCP server, note the skill for implementation phase
  • Language-specific skills (typescript-mastery, etc.) → Incorporate coding standards from that skill into IMPLEMENTATION.md

Mention relevant skills naturally: "You have a react-app-planner skill — want me to use it for deeper React architecture decisions after we finish the high-level plan?"
