design

design is a skill for Claude Code from minusblindfold/devloop. It costs 39 tokens per session (889 once invoked), scanned A, original, MIT.

A design-planning workflow that turns an approved feature plan into an architecture document, diagrams, and detailed task specifications.

In plain words
What is it for?
It is for designing a feature from an existing plan, documenting dependencies and structure, and saving the result as a project design.
Why use it?
It gives implementation a reviewed technical direction and exposes unclear decisions before code is written.

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

design 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Execute each section in order. Copy the checklist and check off items as you complete them. Do not proceed past a Gate until verified.

Artifact: Write to .work/designs/. Verify with ls before wrapping up.

Constraint: Do not write code. This skill produces a design, not an implementation.

Mode

Check .work/active/ for marker files. If exactly one exists and no $ARGUMENTS provided, auto-select that feature's slug. If multiple markers exist, list them, offer to archive any with date older than 30 days to .work/archive/, then ask. Arguments always override.

If $ARGUMENTS (or auto-selected slug) is set → check designs for match (refine), then plans for match (create). No match → print "Run /dl:plan first." and stop. Ambiguous → list and ask. If $ARGUMENTS is empty → list designs; none: fall through to plan picker; one: offer refine or new; many: numbered list. Plan picker: list plans; none → stop; one → auto-select; many → ask.

Task Progress:
- [ ] Determine mode
- [ ] If refine: show current design, ask what to change, iterate, write once
- [ ] Read plan: extract tasks and dependencies
- [ ] Gather context: CLAUDE.md, project scan
- [ ] Ask 2-3 clarifying questions (only unresolved items)
- [ ] Write Overview and Architecture
- [ ] Write Task Specs
- [ ] Write Mermaid diagrams to .work/designs/diagrams/ (see diagrams.md)
- [ ] Write design to .work/designs/
- [ ] Gate: verify design and .mmd files with ls; update active marker
- [ ] Present design for review — primary checkpoint before implementation

Context gathering

Read the plan — extract name, tasks, and dependencies. List them in your response. Read CLAUDE.md if present. Scan the project directory.

Clarifying questions

Ask 2-3 clarifying questions. Read prior artifact decisions — only ask about genuinely unresolved items. Wait for answers.

Task specs

Write a spec for each plan task: Goal, Interfaces, Implementation notes, Acceptance criteria, Tests, Dependencies. In the Tests field, write concrete verification steps that implement can run immediately after completing the slice — not a deferred test plan. Note applicable rules by title (e.g., **Rules:** JPA Entity Rules) — this tells /dl:implement which rule docs from devloop/rules/ to apply.

Changes

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.

design is a skill published in the GitHub repository minusblindfold/devloop (1 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 889 once invoked, about $0.0002 per session on Opus 5.5. 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.
