agentspec: Skill for Claude Code

.claude/skills/sdd-ship/SKILL.md

sdd-ship is a skill for Claude Code from luanmorenommaciel/agentspec. It costs 182 tokens per session (2,497 once invoked), scanned A, original, MIT.

A final phase of a specification-driven development workflow that verifies a completed feature and archives its planning, design, and build documents. It also records lessons learned and marks the documents as shipped.

In plain words
What is it for?
It helps check release readiness, organise feature archives, update workflow statuses, and clean temporary working folders.
Why use it?
It closes the development cycle with evidence that the feature is complete and preserves the decisions and results for later reference.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

sdd-ship 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 7d 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.

SDD Ship — feature archival and lessons learned (Phase 4)

Ship closes the 5-phase SDD workflow: it turns a completed feature's working documents into a permanent archive with lessons learned, marks every phase document Shipped, and leaves the working folders clean for the next feature. Nothing ships unless the build is verifiably complete.

Contract

Aspect Value
Input (required) .claude/sdd/features/DEFINE_{FEATURE}.md · .claude/sdd/features/DESIGN_{FEATURE}.md · .claude/sdd/reports/BUILD_REPORT_{FEATURE}.md
Input (optional) .claude/sdd/features/BRAINSTORM_{FEATURE}.md (if Phase 0 was used)
Output .claude/sdd/archive/{FEATURE}/ containing all artifacts + SHIPPED_{DATE}.md

Contract source .claude/sdd/architecture/WORKFLOW_CONTRACTS.yaml (ship:, status_transitions:, folder_structure:, naming:)

Naming rules (from the contracts): feature names are SCREAMING_SNAKE_CASE (e.g., USER_NOTIFICATIONS); the archive folder is .claude/sdd/archive/{FEATURE_NAME}/; the shipped file is SHIPPED_{YYYY-MM-DD}.md, dated with the ship date.

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.
