chatto-api-compatibility

Review or design Chatto public API and protocol changes for temporal compatibility, capability discovery, version skew, migration impact, and generated artifacts. Use whenever changing or reviewing public protobufs, ConnectRPC handlers, discovery metadata, realtime frames or behaviour, public auth/error/pagination/visibility semantics, or bundled client/server compatibility.

Quality

Content

100%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, token-efficient review skill: a clear sequenced workflow with verification, concrete classification and checklists, and clean section organization without concept padding or unnecessary indirection.

DimensionReasoningScore

Conciseness

Lean and dense with domain-specific guidance; it never explains concepts Claude already knows (protobufs, ConnectRPC, realtime) and every section earns its tokens.

3 / 3

Actionability

Provides a concrete four-way classification (Additive/Behavioural/Deprecated/Breaking), specific named checks ('Connect error codes and absence semantics', 'realtime hello, heartbeat, reconnect, and catch-up behaviour'), and a named tool ('Run Buf breaking checks') — actionable guidance for an instruction-only review skill.

3 / 3

Workflow Clarity

A clearly sequenced 7-step Workflow culminating in an explicit verification step ('Verify protobuf comments, generated Go/TypeScript, generated API reference, tests, FDR/ADR links'), with a guard against declaring Buf-clean changes semantically compatible.

3 / 3

Progressive Disclosure

No bundle files exist and none are needed; the body is well-organized into one-level sections (Source Of Truth, Covered Surfaces, Workflow, Compatibility Checks, Output) pointing only to source-of-truth repo docs rather than nested skill references.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that pairs concrete capabilities with an explicit 'Use whenever' trigger and natural domain keywords. It is both specific and distinctive, with no vagueness or over-claiming.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Review or design', 'temporal compatibility, capability discovery, version skew, migration impact, and generated artifacts' — rather than vague language.

3 / 3

Completeness

Clearly answers both what ('Review or design Chatto public API and protocol changes for...') and when with an explicit 'Use whenever changing or reviewing...' trigger clause.

3 / 3

Trigger Term Quality

Covers natural terms a user would say when needing this skill — 'public protobufs, ConnectRPC handlers, discovery metadata, realtime frames', 'auth/error/pagination/visibility semantics'.

3 / 3

Distinctiveness Conflict Risk

Scoped to a clear niche — Chatto public API/protocol compatibility — with distinct triggers unlikely to fire for unrelated skills.
