Content

75%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 body delivers excellent, copy-paste-ready CLI guidance with a clear connection lifecycle and state-based checkpoints, and is well organized for a single-file skill. Its main weaknesses are moderate padding (concept intro, duplicated search guidance, a sloppy Agent Types aside) and dangling step references ('Step 2', '1b') that break the workflow numbering.

Suggestions

Label the workflow steps explicitly ('Step 1', 'Step 2') so the 'skip to Step 2' and '#### 1b' references resolve to real sections.

Trim the intro paragraph explaining what Astronomer/Airflow is, tighten the 'Agent Types' aside, and deduplicate the action-list command shown in both 'Searching for actions' and 'Popular actions'.

Either flesh out or remove the bare 'Astronomer Overview' bullet list (Deployment/Release/Workspace/User/Token) — as written it adds no actionable guidance.

DimensionReasoningScore

Conciseness

The core CLI guidance is efficient, but there is noticeable padding: an intro explaining what Astronomer/Airflow is ('Astronomer is a modern data orchestration platform powered by Apache Airflow. It's used by data engineers and data scientists...'), a rambling 'Agent Types' aside ('Those will be used to adjust tooling to be used best with your harness'), and the same action-list command duplicated in 'Searching for actions' and 'Popular actions'. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than level 4, where excess would be only minor.

3 / 5

Actionability

Commands are fully executable and copy-paste ready: install ('npm install -g @membranehq/cli@latest'), login including the headless flow ('membrane login complete <code>'), connection setup with polling ('membrane connection ensure "https://astronomer.io" --json' plus '--wait'), action discovery and execution with JSON input ('membrane action run <actionId> --connectionId=CONNECTION_ID --input '{"key": "value"}' --json'), and a complete proxy flag table. Specific examples cover the common cases.

5 / 5

Workflow Clarity

The sequence (install → login → connection → discover actions → run → proxy fallback) is clear with explicit state-based checkpoints (READY / BUILDING / CLIENT_ACTION_REQUIRED with re-poll guidance and error states). It is not level 5 because 'skip to Step 2' references a step that is never labeled and '#### 1b' implies an unlabeled '1a', leaving the numbering incoherent.

4 / 5

Progressive Disclosure

The single-file structure is well organized with clear section headers (Install, Authentication, Connecting, Searching, Running, Proxy, Best practices) and no bundle files exist or are needed at this size. It is not level 5 because the bare 'Astronomer Overview' bullet list (Deployment/Release/Workspace/User/Token) has no depth, links, or stated purpose — a minor organization gap.

Description

57%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 has an explicit 'Use when' clause and a distinctive product name, giving it acceptable completeness and low conflict risk. However, its capability statement is generic ('manage data, records, and automate workflows') with no concrete Astronomer-specific actions, and trigger term coverage is limited to the product name alone.

Suggestions

Replace the generic action list with concrete Astronomer capabilities, e.g. 'Deploy and manage Apache Airflow DAGs, manage deployments, workspaces, users, and API tokens'.

Add natural trigger synonyms users would actually say — 'Airflow', 'data pipelines', 'orchestration', 'DAGs' — to broaden keyword coverage beyond just 'Astronomer'.

Make the 'Use when' clause more specific with concrete triggers, e.g. 'Use when the user mentions Astronomer, Airflow deployments, or data pipeline orchestration.'

DimensionReasoningScore

Specificity

"Manage data, records, and automate workflows" names the Astronomer domain but the actions are generic; no concrete capabilities like deploying Airflow DAGs or managing deployments, workspaces, or tokens. This matches the anchor 'names the domain but actions are minimal or generic' and not level 3, which requires 1-2 concrete domain-specific actions.

2 / 5

Completeness

Both a what ("Astronomer integration. Manage data, records, and automate workflows") and an explicit when ("Use when the user wants to interact with Astronomer data") are present, so it is above level 3 where 'when' is missing or only implied. It falls short of level 5 because the 'what' is generic and the 'when' lacks concrete trigger phrases.

4 / 5

Trigger Term Quality

"Astronomer" is a natural user term (used twice) but the description includes no synonyms or variations users would say such as Airflow, data pipelines, orchestration, or deployments. This matches 'some relevant keywords but missing common variations or synonyms' rather than level 4, which expects good keyword coverage.

3 / 5

Distinctiveness Conflict Risk

"Astronomer" establishes a clear niche with a distinct trigger, keeping conflict risk low, but the generic "manage data / automate workflows" phrasing leaves minor overlap risk with generic data-automation or Apache Airflow skills. Not level 5 because the triggers are not fully distinctive beyond the product name.
