dominicode-sdd-creator

dominicode-sdd-creator is a skill for Claude Code from bezael/sdd-creator. It costs 101 tokens per session (5,855 once invoked), scanned B, original, MIT.

A guided Spec-Driven Development workflow for non-trivial software features and products. Spec-Driven Development means writing the requirements and implementation plan before writing code, then verifying the result.

In plain words
What is it for?
Use it to create spec.md, plan.md, and tasks.md, guide implementation, verify and fix the work, review the code, and prepare a pull request or handoff.
Why use it?
It turns a vague request into documented decisions, tasks, checks, review, and a final handoff, reducing missed requirements during larger changes.

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 B, and why

dominicode-sdd-creator scanned grade B with 1 finding 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 12d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

- **State the cost once, in one sentence, without moralizing:** no regression detection, no confident refactoring, and every acceptance criterion gets verified by hand instead of by a runner.

Dominicode SDD Creator

This skill turns a vague product idea or issue into a complete, evidence-driven SDD lifecycle. Code still starts only after Spec → Plan → Tasks, and completion requires verification, review and a final regression gate.

SDD adaptation by Bezael Pérez · Dominicode.

The methodology in one sentence

Understand → Spec → Plan → Tasks → Implement → Verify (Fix → Verify on failure) → Code Review → Final Verify → PR / Handoff.

spec.md, plan.md and tasks.md are the durable sources of truth. Evidence, review and final verification prove those decisions were satisfied; .work/implementation.md remains disposable execution scratch.

When to use this skill

Trigger this skill at the start of any non-trivial coding work, even if the user did not say the word "spec". Signals:

  • Phrases like "I want to build...", "let's create...", "spec this out", "plan this feature", "design X", "scaffold a new project", "start a new MVP"
  • A feature description without prior planning artifacts in the conversation
  • A coding request that touches more than one module, layer, or screen
  • A request that would normally generate >100 lines of code

Do not trigger for:

  • Bug fixes with a clear repro
  • Small refactors with a single file in scope
  • Pure questions ("how does X work?")
  • Continuing work on a feature where a specs/<name>/spec.md already exists (read it instead)

Workflow (hybrid mode)

Step 0 — Detect the context level

Look at the conversation so far and classify what the user has given you:

Level Signal Action
HIGH Detailed PRD, ticket, doc, or 3+ paragraphs of context Produce a full draft of the 6 sections + list "Open questions" at the end
MEDIUM 1–2 sentences with clear goal but missing detail Produce a draft, mark unknowns with [NEEDS CONFIRMATION: ...] inline
LOW Vague request ("quiero hacer una app de X") Interview the user one section at a time — do NOT dump all 6 questions at once

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.
