stream-feeds-migration

Generate the v2 -> v3 sync mapping for a Stream Activity Feeds app by sampling its live v2 activities and reactions. Use when setting up a Feeds v2 to v3 migration, when asked to build, review, or debug a v3 sync mapping, when someone asks 'what mapping do we need for our app?', or when a migrated activity lands in v3 with missing text, missing attachments, comments that are not comments, or bookmarks that went missing. Triggers on v3sync, v2 to v3, feeds migration, activity feeds migration, sync mapping, extra_context, reaction kinds, comments and bookmarks mapping. The same mapping drives both the live syncer and the bulk exporter.

Quality

Content

92%Weight 40%Scale 1-5

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 and well-structured, with a clear sequenced workflow, explicit validation, and clean progressive disclosure to a real reference file. Only minor conciseness tightening would raise it further.

DimensionReasoningScore

Conciseness

Lean and competence-assuming throughout - no padding about what Stream/Feeds is - but a few explanatory passages (e.g. the rationale for the `!` prefix, the legacy layout flag aside) could be trimmed slightly.

4 / 5

Actionability

Fully executable guidance: exact fetch command, presence-check command, export invocation, named endpoints, and a copy-paste-ready JSON output example covering the common cases.

5 / 5

Workflow Clarity

A clear 5-step sequence with explicit validation checkpoints (secret presence check, 401/403/404 diagnostics, empty-array handling) and a Limits-of-the-sample checklist that functions as an error-recovery/feedback loop.

5 / 5

Progressive Disclosure

The body is an overview that consistently delegates the full key catalogue to the real one-level-deep references/mapping-keys.md, with a bundled script and well-organized sections for easy navigation.

Description

92%Weight 40%Scale 1-5

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, complete, and distinctive, clearly stating what it does and when to use it with concrete, natural trigger phrases. It only loses a point on trigger_term_quality for a few missing common synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions - 'Generate the v2 -> v3 sync mapping', 'sampling its live v2 activities and reactions', and notes the mapping drives 'both the live syncer and the bulk exporter' - covering the task comprehensively.

5 / 5

Completeness

Explicitly answers both 'what' (generate the v2->v3 sync mapping by sampling live data) and 'when' (Use when setting up a migration, building/reviewing/debugging a mapping) with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural trigger coverage ('v3sync, v2 to v3, feeds migration, sync mapping') plus diagnostic phrases users would say ('missing text', 'comments that are not comments'), with a few common synonyms still absent.

4 / 5

Distinctiveness Conflict Risk

A clear, narrow niche (Stream Activity Feeds v2->v3 migration mapping) with domain-specific triggers unlikely to fire for any unrelated skill.
