Conciseness

The body is dense with Orchestra-specific, non-obvious facts (5-digit suffix semantics, the <INTEGRATION>__<CONNECTION_ID>__<FIELD> naming scheme, credential-store read behavior) and assumes Dagster/YAML knowledge, but a few passages could be trimmed ("Read it back rather than asking someone to find it: connections are managed through ... as well as the UI", "This mirrors how Dagster swaps resources per deployment/environment"). It is efficient with minor over-explanation, matching anchor 4 rather than 5 where every token would earn its place.

Actionability

Guidance is copy-paste ready: complete YAML snippets (connection: my_snowflake_12345, ${{ ENV.SNOWFLAKE_CONN }}, inputs: blocks), full resource-to-connection mapping tables with key fields, an exact SDK call (orchestra.get_linked_connection("snowflake", connection_id="prod_12345")), a profiles.yml env_var snippet, and a concrete setup checklist. Not a 4 because no common case lacks executable detail; connection creation via API is delegated to a documented reference rather than left vague.

Workflow Clarity

The "Connection Setup Checklist" gives a clear sequenced process and validation checkpoints appear inline ("Orchestra reads the secret when the connection is saved and rejects it if it can't be read or its keys don't match", "Check a variable exists rather than assuming it"), but there is no explicit validate-then-fix-then-retry loop for the overall migration. This matches anchor 4 (most checkpoints present, minor validation gaps) rather than 5 (explicit feedback loops).

Progressive Disclosure

With no bundle files present, the single-file skill is well organized: clear section headers, scoped tables, a setup checklist, and a clearly listed References section of external docs. It falls short of anchor 5 because the ~211-line body carries large lookup tables (the resource-type mapping section) that would naturally split into a one-level-deep reference file in a progressively disclosed bundle.

Specificity

The description names the domain ("converting Dagster code that references resources holding credentials ... to Orchestra") and enumerates concrete entities ("ConfigurableResource subclasses, EnvVar, integration resources like SnowflakeResource / S3Resource / DbtCliResource, or resources wired into Definitions"), but the action set is a single conversion task rather than several distinct actions, so it sits between the 3 and 5 anchors.

Completeness

Both what ("converting Dagster code that references resources holding credentials ... to Orchestra") and when ("Use this skill when ... Triggers: any Dagster resource that stores host/login/token/key, any EnvVar used for credentials, or environment-specific resource configuration") are explicitly stated with concrete trigger phrases, matching the anchor-5 example structure. A 4 would require the when-clause to be less explicit, which it is not.

Trigger Term Quality

It comprehensively covers the natural terms a user doing this migration would say — "Dagster resource that stores host/login/token/key", "EnvVar used for credentials", "environment-specific resource configuration", "connection: field" — including synonyms for the credential shapes (host/login/token/key). Not below 5 because no common phrasing in this niche is missing; not applicable above since 5 is the maximum.

Distinctiveness Conflict Risk

It carves a clear niche — Dagster-to-Orchestra credential/connection migration — with distinct triggers (credentialed resources, EnvVar for credentials, connection: fields in Orchestra YAML) that no generic or sibling skill would naturally claim. Not a 4 because the trigger scoping leaves no meaningful overlap with adjacent conversion skills.
