Claude Skills and Plugins consulting

Every department has a way it wants things done: the proposal outline sales leadership approved, the variance thresholds finance uses, the words marketing never prints. Today that knowledge lives in a few people's heads and a shared drive nobody opens, and employees retype it into every Claude conversation. A Skill packages it once. Each Skill has a SKILL.md file with a short name and description, followed by instructions, plus optional reference files, templates and scripts. Claude reads only the name and description up front, opens the full instructions when a request matches, and opens extra files only when a step calls for them. That design lets a company keep many Skills without crowding every conversation.

1. 01

   Skills, plugins, connectors and projects are different tools

   Buyers mix these up, and the mix-up leads to wrong designs. A Skill teaches Claude how to do a task. A connector gives Claude live access to a system, such as SharePoint or your ticketing tool; a Skill cannot reach a service by itself, but it can tell Claude how to use a connector. A plugin bundles several Skills with the connectors, commands and agents they need, so a team installs one package instead of six parts. A project holds background knowledge that is always loaded in that project's chats. Instructions that should apply to every conversation belong in preferences or project instructions, not a Skill, because a Skill loads only when a request matches its description.

   Where company Skill libraries go wrong

   The first failure is a vague description. If it says "helps with documents", Claude cannot tell when to use it, and two broad Skills start stealing each other's requests. The second is credentials: an API key pasted into a script ships to everyone the Skill is shared with. The third is ownership. A Skill written by an enthusiast in March encodes March pricing, and nobody updates it after that person changes roles. The fourth is skipping review because Skills look like plain text. A Skill can run code and direct Claude to call tools, so Anthropic tells enterprises to treat installing one like installing software. Each of these failures shows up as wrong output, not as an error message.

   Why Abstrakt Solutions

   We have spent years turning sales, service and operations processes into Salesforce flows, validation rules and approval chains, and a Skill is the same exercise written in plain language. We interview the people who do the work, collect three real examples of good output, write the evaluation cases before the instructions, and test each Skill against prompts that should and should not trigger it. We then set up the organization library: who can publish, who reviews, how versions roll back, and which groups get which plugins. Because we also build connectors and custom MCP servers, we can write the Skill and the system access it depends on in one project. The consultants who write your Skills hold Claude certifications, 12 across the team, and Abstrakt is a Certified Services Partner in the Claude Partner Network.

The engagements we run most often on Claude Skills and Plugins, from first implementation through optimization.

1. 01

   Pick five workflows and gather real examples

   Department heads nominate tasks people repeat weekly. For each, we collect three examples of good finished work, one example of a common mistake, and the written rules if any exist. We drop tasks that need data Claude cannot reach yet and tasks where nobody agrees on the standard. A named business owner signs up for each of the five that survive; that person approves content and answers questions after launch.

2. 02

   Write the tests before the instructions

   Anthropic recommends building evaluations first, and so do we. For each Skill we write three to five test prompts: requests that should trigger it, requests that should not, and ambiguous ones. We run them without the Skill to record a baseline. Then we write the shortest instructions that close the gaps, add templates and scripts only where a step must be exact, and rerun until the Skill beats the baseline.

3. 03

   Review security and coexistence

   A reviewer who did not write the Skill reads every file. They check for hard-coded credentials, network calls, instructions to hide actions, and references to tools the Skill should not use. We then test the new Skill alongside the existing library, because a broad description can steal requests from other Skills. On Enterprise we turn on Skills and plugins scanning before the first upload so new items are scanned automatically.

4. 04

   Package, publish and assign

   Skills for one team go into one plugin. We upload it or sync it from your private repository, set its availability, and on Enterprise assign it by group so finance does not see sales Skills. Bundled connectors are added in Organization settings > Connectors separately. We usually start with Installed by default for the pilot team and move to Required only for Skills that encode a policy everyone must follow.

5. 05

   Assign owners and a change process

   Each Skill gets an entry in a simple registry: purpose, business owner, current version, dependencies and last test date. Changes go through pull requests in the repository, the tests rerun before merge, and the owner approves. We set publishing to Requires review so member-built Skills get the same check. A quarterly review uses the Users (30d) column to retire Skills nobody uses.

1. 01

   Writing descriptions for humans, not for matching

   Claude decides whether to load a Skill from its description alone. Name the task and the words people use to ask for it, in third person, or the Skill never fires.

2. 02

   One giant Skill per department

   Anthropic advises starting narrow and consolidating only when tests show no loss. Several focused Skills combine better than one that tries to cover every request.

3. 03

   Putting secrets in scripts

   Everyone a Skill is shared with receives its files. Use a connector so each person signs in with their own account.

4. 04

   No owner after launch

   Pricing, policy and templates change. Without a named owner and a review date, a Skill keeps producing last year's answer with full confidence.
