Tessl • The management layer for AI agent skills

The body is a strongly actionable integration guide: copy-paste-ready Membrane CLI commands for auth, connection setup with state-machine handling, action discovery/execution, and proxy fallback. Main weaknesses are the broken step references ('Step 2', '1b' with no matching labels), the low-value bare entity list, and no validation guidance for action results or destructive operations.

Suggestions

Fix the incoherent step numbering: either label the sections 'Step 1'/'Step 2' consistently or replace 'skip to **Step 2**' and '#### 1b.' with descriptive headings.

Cut or enrich the 27-item bare entity list ('**Matter**', '**Note**', ...) — either move it to a reference file or annotate entries with what each object is for; also delete the filler line 'Use action names and parameters as needed.'

Add a validation step after running actions — e.g. check the output/error fields of 'membrane action run' before proceeding, especially before destructive actions like delete-lead.

Dimension	Reasoning	Score
Conciseness	The body is mostly lean, executable command blocks and tables with no over-explanation of concepts Claude already knows. The 27-item entity list under 'CINC Overview' (e.g. 'Matter', 'Note') is bare names with no accompanying guidance and reads as padding, plus the filler line 'Use action names and parameters as needed.' — minor trimmable instances matching score 4 rather than the fully lean score 5.	4 / 5
Actionability	Every section gives copy-paste-ready commands with exact flags: 'npm install -g @membranehq/cli@latest', 'membrane connection ensure "https://www.cincpro.com/" --json', 'membrane action run <actionId> --connectionId=CONNECTION_ID --input ... --json', plus a flags table for proxy requests and a 14-row popular-actions table covering common cases. It is fully executable and covers the common cases, matching the score 5 anchor.	5 / 5
Workflow Clarity	The sequence (install → login incl. headless flow → connect → poll state → search → run) is clear, with a genuine feedback loop for connection states (READY / CLIENT_ACTION_REQUIRED / CONFIGURATION_ERROR with clientAction fields to inspect). It falls short of 5 due to incoherent step numbering — 'skip to Step 2' and '#### 1b.' reference steps that are never labeled elsewhere — and no validation guidance for action-run results or destructive actions like delete-lead, which are minor gaps fitting score 4's 'most checkpoints present'.	4 / 5
Progressive Disclosure	No bundle files exist, so all content is necessarily inline in SKILL.md; sections are clearly headed and easy to navigate (CLI setup, connection, actions, proxy, best practices). The bare entity list and full actions table are content that could live in a separate reference file if a bundle were used, which keeps it at 'Good structure; most content appropriately placed; minor organization gaps' rather than 5.	4 / 5

Description

48%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 correctly uses third person, has an explicit 'Use when' clause, and anchors on the distinctive CINC product name. Its weakness is the 'what' half: 'Manage data, records, and automate workflows' is generic filler that could describe any integration, with no concrete capabilities (lead management, notes, agents, webhooks) that this skill demonstrably supports.

Suggestions

Replace the generic 'Manage data, records, and automate workflows' with concrete capabilities drawn from the skill, e.g. 'Manage leads, agents, labels, notes, and webhook subscriptions in CINC (real estate CRM)' to raise specificity and completeness.

Add natural trigger terms and synonyms users would actually say — e.g. 'CINC, CINCpro, real estate CRM, leads' — so the description fires on realistic phrasings.

State the integration mechanism briefly (e.g. 'runs CINC actions via the Membrane CLI') to sharpen the 'what' and further reduce overlap with other data-management skills.

Dimension	Reasoning	Score
Specificity	"Manage data, records, and automate workflows" names the domain (CINC) but the actions are minimal and generic — no concrete operations like retrieving leads, creating notes, or managing transactions that the skill actually supports. This matches the anchor 'Names the domain but actions are minimal or generic' and falls below score 3, which requires 1-2 concrete named actions.	2 / 5
Completeness	The 'when' is explicit ("Use when the user wants to interact with CINC data") but the 'what' is vague — "Manage data, records, and automate workflows" describes virtually any integration. Because the what half is generic, this sits between the score 3 anchor (clear what, weak when) and score 4 (both present, when could be more specific), and the vague 'what' pulls it to 3.	3 / 5
Trigger Term Quality	"CINC" is the key natural term a real estate agent would say, and "data"/"records" add mild relevance, but common variations are missing (e.g., "leads", "real estate CRM", "CINCpro"). This fits 'Some relevant keywords but missing common variations or synonyms' rather than score 4, which expects good keyword coverage with only a few natural terms missing.	3 / 5
Distinctiveness Conflict Risk	"CINC" is a distinctive product name giving a clear niche with minimal conflict risk, but the surrounding phrases ("Manage data, records, and automate workflows") are generic and could overlap with other integration skills. Mostly distinct with minor overlap risk — score 4 rather than 5 because the generic action language isn't tied to CINC-specific triggers like leads or real estate CRM.	4 / 5
