blueprint

blueprint is a skill for Claude Code from itsribbZ/Godspeed. It costs 179 tokens per session (3,863 once invoked), scanned A, original, MIT.

A step-by-step planning guide for designing and deploying game systems or other software features, with project scanning and research built in.

In plain words
What is it for?
It is for creating production-ready blueprints with concrete code locations, classes, phases, research, and deployment steps for projects such as Unreal Engine games or SaaS applications.
Why use it?
It turns a broad feature request into a detailed implementation plan tied to the existing codebase and project documentation.

Skill for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter; mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

blueprint 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 6d 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.

The opening of the file, as written. The whole thing — 297 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Blueprint — Actionable Implementation Blueprint Skill v2.0

You are a senior technical architect producing a production-ready implementation blueprint for your project. Your output is not research — it is a precise, phased deployment plan with specific code, classes, and steps that can be followed exactly.

Pre-work: Follow ${CLAUDE_PLUGIN_ROOT}/shared/_shared_protocols.md §1.

Project Context

Project-agnostic. Paths loaded dynamically from project init skills:

  • UE5/your project: Source root, docs root, PDF output, project docs, Variant folders detected from your-project-init
  • SaaS projects: Detected from project package.json and framework configs
  • Any project: PDF output defaults to project root + /docs/research/
  • Quality bar and architecture: Inherited from project's CLAUDE.md or init skill

Workflow

Phase 0: Session Marker (PRE-EXECUTION — shell-append, compaction-resistant)

CRITICAL per SL-046/SL-062: Fire this Bash command IMMEDIATELY on invocation, BEFORE Phase 1 scan. Blueprint's _learnings.md was stuck at 22 lines / 1 entry despite v2.1 checkpoint claim — the fix did not fire because writes were queued for end-of-phase and context compaction ate them.

SKILL_DIR="$HOME/.claude/skills/blueprint"
TS="$(date +%Y%m%d_%H%M%S)"
DATE="$(date +%Y-%m-%d)"
printf '\n### Session Marker: blueprint — %s\n<!-- meta: { "run_id": "blueprint_%s", "domain": "pending", "confidence": "PENDING", "confirmed_count": 0, "roi_score": null, "staleness_check": "%s" } -->\n\n**Phase**: Pre-execution\n**Status**: Session started — topic TBD\n**Action**: Full checkpoint written after Phase 2 research; this marker persists if run is interrupted\n' "$DATE" "$TS" "$DATE" >> "$SKILL_DIR/_learnings.md"

One Bash call. Not an Edit. Shell writes outside Claude's context, so the marker survives compaction. This is non-negotiable — the entire v2.1 incremental checkpoint discipline is dead weight without this shell-append landing first.

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.

blueprint is a skill published in the GitHub repository itsribbZ/Godspeed (1 stars, last pushed 2mo ago), licensed MIT. It adds 179 tokens to every session and 3,863 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
