Conciseness

The body is dense and assumes competence (no explanation of what Dagster or Slack is), but the core mapping (e.g., "make_slack_on_run_failure_sensor -> pipeline-level alert, statuses: [FAILED]") is restated across the Decision Guide, Conversion Steps, Gotchas, and Before/After sections. Not 5 because that repetition could be trimmed; not 3 because each restatement serves a distinct reading mode and there is no padded explanation.

Actionability

Fully executable guidance: complete YAML for both the alerts block and the SLACK/SEND_SLACK_MESSAGE task, exact field schemas ("Required parameter: channel_name; at least one of text, blocks, or attachments"), a copy-paste before/after pair, and the literal connection-setup path. Covers the common conversion cases end to end.

Workflow Clarity

The 5-step Conversion Steps section is clearly sequenced (identify usage → map sensors/hooks → map op-level hooks → convert in-op messages → create connection) and anchored by the Decision Guide table. Not 5 because there is no validation checkpoint (e.g., verifying the produced YAML or test-firing the alert); the operation is low-risk config authoring, so the destructive/batch cap does not apply.

Progressive Disclosure

No bundle files exist; the single SKILL.md is well-organized with clear section headers and a flat, one-level References list of external doc URLs. Not 5 because at ~175 lines the AlertModel/AlertDestinationModel schema tables and the full dbt+Slack task example are inline content that could be split into reference files (the under-50-line exception doesn't apply).

Specificity

Enumerates the exact source constructs ("SlackResource, make_slack_on_run_failure_sensor, make_slack_on_freshness_policy_status_change_sensor, or op success/failure hooks that post to Slack") and the concrete targets ("Orchestra pipeline alert or task"), giving comprehensive, explicit coverage of the conversion domain. Not 4 because coverage of the domain's patterns is complete rather than having minor gaps.

Completeness

Explicitly answers both: what ("convert Dagster Slack notifications … into an equivalent Orchestra pipeline alert or task") and when ("Use this skill when the user wants to…" plus a dedicated "Triggers:" clause with concrete trigger phrases). Not 4 because the 'when' is not merely present but spelled out with multiple explicit trigger conditions.

Trigger Term Quality

Natural triggers include "migrating or rewriting Dagster Slack notifications to Orchestra" plus code-level cues ("importing from dagster_slack", "@success_hook/@failure_hook functions that send Slack messages") — terms a user with this need would genuinely say. Not 5 because synonym coverage is thin (e.g., "porting", "moving", "Slack alerts") beyond the two verbs given.

Distinctiveness Conflict Risk

A clear niche (Dagster→Orchestra Slack notification migration) with highly specific triggers (named sensors, dagster_slack imports, hook decorators) that no other plausible skill would match. Not 4 because overlap risk is essentially nil, not just minor.
