review-shared

A review procedure for shared code and data contracts used by a server and web application. It checks types, validation, defaults, state transitions, serialization, and all affected consumers.

In plain words
What is it for?
Use it to review changes in shared packages, verify valid and malformed data paths, check compatibility impacts, and produce the required review JSON.
Why use it?
It helps prevent different parts of the application from disagreeing about valid data or breaking when shared formats and state changes evolve.

Per session 25 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 264 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

review-shared 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 2d 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

Review Shared

Responsibility

Review changes under packages/shared and every affected consumer. Findings only; no edits or GitHub mutation.

Run in a fresh context with shared source/tests, server and web consumers, accepted plan, exact diff and verification evidence.

Lenses

  • The concept is truly shared and serializable; host-only or UI-only behavior stays with its owner.
  • Runtime guards, defaults, reducers and TypeScript types describe the same valid states.
  • Discriminated unions are exhaustive and invalid combinations are unrepresentable or rejected at a boundary.
  • Workspace/layout and automation transitions preserve IDs, references and invariants for every operation order.
  • Wire-shape changes update producers, consumers, fixtures and runtime validation together.
  • Compatibility impact is explicit and no compatibility layer appears without user approval.
  • Tests include valid round trips, malformed serialized data, sibling variants and revert-failing state transitions.

Output

Produce .agents/schemas/review.schema.json with subject: "implementation" and reviewer_role: "review-shared".

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.

review-shared is a skill published in the GitHub repository davidomil/cloudx (1 stars, last pushed 9d ago), licensed MIT. It adds 25 tokens to every session and 264 once invoked, about $0.0001 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.
