How this analysis is made

Examples

Add context window property
Add a new property called 'contextWindow' with label 'Context Window' and tooltip 'The maximum number of tokens the agent can handle in a single request.' It should be a badge type and belong to the features group.
Add pricing tier property
I need to add a 'pricingTier' property to the agents database. It's a text field under the 'identity' group. Display label 'Pricing Tier', tooltip 'Free, Pro, or Enterprise tier'.

name: add-agent-property description: Add a new property to the AI agents database. Use when the user wants to add, create, or introduce a new column, property, field, or feature to track across all agents in the comparison matrix. Handles all four required steps - database updates, groups.json, table display, and GitHub issue templates.

Add Agent Property

Add a new property to the agents board by modifying four files in sequence.

Schema reference: See references/schema.md for data structures.

Workflow

1. Gather Property Details

Ask the user for:

  • Property key (camelCase, e.g., contextWindow)
  • Display label (short, e.g., "Context Window")
  • Tooltip description (1 sentence explaining the property)
  • Cell type: badge (yes/no/partial) or text (free-form)
  • Group: identity, packaging, or features

2. Update agents-detailed.json

Add the property to every agent in src/data/agents-detailed.json:

"propertyKey": {
  "value": null,
  "detail": null
}

Insert after the last feature property, before additionalInfo.

3. Update groups.json

Add the property key to the appropriate group's columns array in src/data/groups.json:

{
  "id": "features",
  "label": "Features",
  "columns": ["existingProp", "propertyKey"]
}

4. Update AgentTable.jsx

Add column definition to the columns array in src/components/AgentTable.jsx:

{ key: 'propertyKey', label: 'Label', sortable: true, cellType: 'badge', tooltip: 'Description' }

Insert at the position matching its group order.

5. Update useAgentsData.js

Add transformation in src/hooks/useAgentsData.js:

propertyKey: agent.propertyKey.value,
propertyKeyDetail: agent.propertyKey.detail,

6. Update FilterBar.jsx (for filterable properties)

If the property is in packaging or features group and has cellType: 'badge', add it to the featureOptions array in src/components/FilterBar.jsx:

{ key: 'propertyKey', label: 'Label' }

Insert in the appropriate section (Packaging or Features) following the existing order.

7. Update GitHub Issue Templates

01-update-agent.md - Add under Features section:

- [ ] **Property Label** (`propertyKey`)
  - New value: <!-- yes/no/partial/null -->
  - Detail:

02-add-new-agent.md - Add new section with property definition, value format, and examples.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/add-agent-property-mm5t89vm/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/add-agent-property-mm5t89vm' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/add-agent-property-mm5t89vm/download' --output '.skill-downloads/add-agent-property-mm5t89vm/SKILL.md.part' && mv '.skill-downloads/add-agent-property-mm5t89vm/SKILL.md.part' '.skill-downloads/add-agent-property-mm5t89vm/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/add-agent-property-mm5t89vm/SKILL.md' && test -s '.skill-downloads/add-agent-property-mm5t89vm/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/add-agent-property' && cp -R '.skill-downloads/add-agent-property-mm5t89vm' '.claude/skills/add-agent-property'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/add-agent-property-mm5t89vm'

openskills read 'add-agent-property-mm5t89vm'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/add-agent-property-mm5t89vm/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
