medharness: Skill for Claude Code

.claude/skills/openspec-continue-change/SKILL.md

openspec-continue-change is a skill for Claude Code from charliehzm/medharness. It costs 157 tokens per session (702 once invoked), scanned A, original, Apache-2.0.

A planning aid that expands an OpenSpec change proposal into detailed technical designs, specifications, acceptance criteria, tests, and risks. OpenSpec is a structured format for describing software changes before implementation.

In plain words
What is it for?
Use it after creating an OpenSpec change to define data models, API or internal contracts, component interactions, failure recovery, performance limits, compliance details, test hooks, and mitigations.
Why use it?
It helps expose missing requirements and unclear technical decisions before coding begins. It also checks that planned product requirements are represented in the specifications.

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

openspec-continue-change 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 13d 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.

What it actually says

OpenSpec Continue Change

The "make it implementation-ready" expansion. After openspec-new-change scaffolds, this fills.

Quality bar — when to stop

The change is ready when every PRD in-scope item maps to ≥ 1 spec row, and every spec row has acceptance criteria.

Workflow

  1. PRD ↔ Spec mapping — list every in-scope item in PRD §3; ensure each has a spec id.
  2. Design body — technical approach for each spec, in design.md:
    • Data model (tables / messages / contracts)
    • API/IPC contracts
    • Component interaction diagram (mermaid acceptable)
    • Failure modes + recovery
    • Performance budgets
  3. Compliance Design — refine the section seeded in openspec-new-change:
    • Mark every L3/L4 field's flow path
    • Specify desensitization points
    • Specify audit log entries this change introduces
  4. Specs — for each spec row:
    • one-line behavior description
    • acceptance criteria (Given/When/Then or list)
    • test hook (which test type, what data)
  5. Risks — top 3 risks + mitigation (in design.md)
  6. Validate — run openspec validate (or openspec-ff-change for fast path) — must pass.

Common failure modes

  1. PRD item without spec — silent drop. Mitigation: explicit PRD↔Spec matrix at the top of design.md.
  2. Acceptance criteria as wishes — "the system should be fast". Mitigation: "P99 < 200ms on stage-mock data".
  3. Compliance afterthought — fill at the end. Mitigation: refine section every time you add a data-touching spec.
  4. Premature implementation — code samples in design.md > 30 lines. Mitigation: design says what, code says how (later).

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.
