launchpad-spec

launchpad-spec is a skill for Claude Code from Geono/claude-launchpad. It costs 59 tokens per session (2,053 once invoked), scanned A, original, MIT.

A framework for planning software work through written specifications and smaller implementation tasks. It uses TDD, meaning tests are written or updated to guide development before the code is completed.

In plain words
What is it for?
Use it to turn an idea into a specification, refine it, answer clarification questions, split it into tasks, and run those tasks.
Why use it?
It reduces unclear requirements and prevents work from starting while important questions remain unanswered.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

launchpad-spec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Launchpad Spec

Iterative feature development framework ensuring zero ambiguity before execution.

Quick Reference

Command Purpose Input
/lp:spec <intent> Create spec from "I want to build/add X" Feature description
/lp:refine [section] Improve spec with research Optional section focus
/lp:clarify <response> Answer clarification questions Your response
/lp:tasks Break spec into executable tasks None (uses active spec)
/lp:run-task [task#] Execute tasks with TDD Optional task number

Core Principle

Iterate until clarity: No task execution begins until ALL questions are resolved and the spec is unambiguous. Claude must be able to execute without interruptions.


Phase 1: /lp:spec - Create Specification

Trigger: /lp:spec <description> or "I want to build/add X"

Workflow

  1. Check specs/ folder:

    • If missing: Create specs/ and specs/README.md
    • If exists: Read specs/README.md for project overrides
  2. Detect project context:

    • Scan repo for language indicators (go.mod, pyproject.toml, package.json, etc.)
    • Note primary language(s) for later skill invocation
    • Check specs/README.md for language overrides
  3. Generate spec file:

    • Filename: specs/{feature-slug}.md (kebab-case)
  4. Fill initial sections:

    • Parse user intent into Objective
    • List initial requirements (functional/non-functional)
    • Mark status as DRAFT
  5. Generate clarifying questions:

    • Identify ambiguities, edge cases, unknowns
    • List as numbered questions in "Open Questions" section
    • STOP and present questions to user

Output

Created: specs/feature-name.md (DRAFT)

Questions requiring clarification:
1. [Question about scope]
2. [Question about behavior]
3. [Question about constraints]

Use `/lp:clarify` to answer, or `/lp:refine` to research solutions.

Phase 2: /lp:refine - Research & Improve

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
