object-modify

Modify a Unity `UnityEngine.Object`'s serializable fields/properties. Three modification surfaces are available (`objectDiff`, `pathPatches`, `jsonPatch`) — see the skill body. Use 'object-get-data' first to inspect the object structure.

Quality

Content

65%

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

The content is highly actionable with real CLI commands and schemas, but schema duplication hurts conciseness, the destructive modify workflow lacks a validation/feedback loop, and large inline schemas could be externalized for better progressive disclosure.

Suggestions

Add a verification checkpoint after modification (e.g. re-run object-get-data or check the response Logs) so the destructive workflow has an explicit validate-and-recover loop.

De-duplicate the Shared JSON-schema definitions (ObjectRef, SerializedMember, SerializedMemberList) between the Input and Output sections, or move the full schemas into a references file and keep only a concise overview inline.

DimensionReasoningScore

Conciseness

The body is mostly lean and assumes Unity knowledge, but the AIGD.ObjectRef, SerializedMember, and SerializedMemberList JSON-schema definitions are duplicated verbatim across the Input and Output sections, adding ~100 redundant lines that could be tightened.

2 / 3

Actionability

Provides concrete, executable commands (unity-mcp-cli run-tool with --input, --input-file, and stdin-pipe patterns) plus a full input table and JSON schemas, matching the copy-paste-ready anchor.

3 / 3

Workflow Clarity

Execution ordering is stated (jsonPatch then pathPatches then objectDiff) and 'At least one is required' is noted, but this destructive modification operation has no validation/verification step or error-recovery loop, capping workflow clarity at 2 per the destructive-operations guideline.

2 / 3

Progressive Disclosure

The body is well-sectioned but exceeds 50 lines and inlines large input/output JSON schemas that could be split into a separate reference file; no bundle files exist to offload detail, so it stops at the 'could be better organized' anchor.

Description

67%

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

The description is specific and distinctive, but it over-relies on internal jargon for triggers and lacks an explicit 'when to use this skill' clause, capping completeness and trigger quality at 2.

Suggestions

Add an explicit 'Use when ...' trigger naming natural phrasings (e.g. when the user asks to edit, change, or update a Unity object's fields/properties or component values).

Soften or front-load plain-language keywords alongside the technical surface names so natural user requests map to the skill more reliably.

DimensionReasoningScore

Specificity

Names a concrete domain ('Modify a Unity UnityEngine.Object's serializable fields/properties') and enumerates three specific modification surfaces (objectDiff, pathPatches, jsonPatch), matching the 'lists multiple specific concrete actions' anchor.

3 / 3

Completeness

The 'what' is explicit, but the only trigger-like phrase ('Use object-get-data first to inspect the object structure') is a prerequisite ordering hint rather than an explicit 'when to use object-modify' trigger, so completeness caps at 2 per the missing-trigger guideline.

2 / 3

Trigger Term Quality

Contains some natural terms ('Modify a Unity', 'object') but leans heavily on technical jargon (UnityEngine.Object, jsonPatch, RFC mechanisms) and omits common phrasings like 'edit', 'change', or 'update Unity object/component', so it stops short of full natural-term coverage.

2 / 3

Distinctiveness Conflict Risk

The Unity object-modification niche with named surfaces is distinct from the companion object-get-data skill and unlikely to trigger for unrelated skills.
