Add Caatinga skill to community ecosystem cards

[Dione-b]

Summary

• Adds Caatinga to ECOSYSTEM_CARDS so it appears on skills.stellar.org and in generated llms.txt.
• Skill source: https://github.com/Dione-b/caatinga-skill/blob/master/skills/caatinga/SKILL.md
• Install (Claude Code plugin marketplace):

  /plugin marketplace add Dione-b/caatinga-skill
  /plugin install caatinga-skill@caatinga-skill
  

• CLI: @caatinga/cli (ctg command)

Why this skill is useful

The catalog's smart-contracts skill covers writing and deploying Soroban contracts with the Stellar CLI directly, but doesn't address the deployment-orchestration layer teams need once a project has multiple interdependent contracts and generated frontend bindings to keep in sync.

Caatinga fills that gap for the ctg workflow:

• Deployment Graph — contracts declare dependsOn in caatinga.config.ts; Caatinga topologically sorts and deploys them in the correct order instead of requiring manual sequencing.
• Versioned artifacts as source of truth — caatinga.artifacts.json tracks contract IDs per network, replacing manual .env copy/paste that drifts on redeploy.
• Generated TypeScript bindings — ctg generate keeps frontend clients in sync with what's actually deployed.
• Credential hygiene — the skill actively steers agents away from passing raw secret keys via --source and from hand-editing generated artifacts/bindings, both common failure modes when an agent falls back to raw stellar CLI commands in a Caatinga-managed repo.

This gives agents working in ctg-based repos (signaled by caatinga.config.ts / caatinga.artifacts.json / CAATINGA_* env vars) opinionated, project-aware guidance instead of generic Stellar CLI advice that would bypass Caatinga's invariants.

Test plan

• node --experimental-strip-types scripts/generate-llms-txt.mjs succeeds and the generated llms.txt includes the new ecosystem card
• Skill on Dione-b/caatinga-skill documents the ctg workflow, hard rules, and install steps
• Confirm card renders under Community skills on the preview deploy
• Optional: install the plugin via /plugin marketplace add Dione-b/caatinga-skill and try a Caatinga-related prompt

Thanks for this, Dione — this is exactly the kind of gap I wanted the ecosystem section to fill (deployment orchestration on top of the raw Stellar CLI, not another wallet or explorer skill), and the SKILL.md itself is unusually careful. I checked the 3.9.2 "Versioning note" claim against the actual CLI changelog: the os.tmpdir() key-leak fix and the ctg sync-env env-file-wipe fix you cite are both real, 3.9.2 is genuinely npm's current latest, and the wallet-adapter / single-invoker claims match docs/wallets.md in the main caatinga repo too.

One thing I want cleared up before this goes on the catalog: the SKILL.md's "Versioning note" section says Caatinga is "pre-1.0 (alpha)," but the main repo's README says the opposite — "v1.0 stable contract on npm major 3.x" — and npm's latest is 3.9.2, well past a 1.0 line. That's a real contradiction an agent reading the skill could act on (e.g. telling someone not to trust it in production when the project itself calls it stable). Could you update or drop that line in skills/caatinga/SKILL.md so it doesn't contradict the project's own README?

Once that's fixed I'm happy to merge — everything else here checked out clean.
