What it does

Provider Adapter Development is an agent skill from AbdelStark/worldforge. Use for WorldForge provider work: adding adapters, changing capability declarations, promoting scaffolds, debugging provider failures, updating provider catalog docs, or touching LeWorldModel, GR00T, LeRobot, Cosmos-Policy, JEPA, Genie, or JEPA-WMS. Ensures capabilities remain truthful and optional runtimes stay host-owned.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Project scaffolding. The repository describes itself as: Harness framework to build world model based workflows for physical AI systems. The licence is MIT.

When your agent uses it

  • WorldForge provider work: adding adapters
  • Changing capability declarations
  • Promoting scaffolds
  • Debugging provider failures

Example prompts

  • “/provider-adapter-development”

Requirements

  • Python 3

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Read the closest existing adapter, then src/worldforge/providers/base.py, src/worldforge/providers/catalog.py, and…
  2. Classify the upstream runtime by what it actually does, not by model marketing language.
  3. For a new scaffold, start with uv run python scripts/scaffold_provider.py ...; keep capabilities unadvertised until real methods return…
  4. Validate public inputs before network calls, filesystem reads, or optional runtime calls.
  5. Return the correct public model: PredictionPayload, EmbeddingResult, ActionScoreResult, or ActionPolicyResult.
  6. Add success and malformed/error fixtures under tests/fixtures/providers/.
  7. Add worldforge.testing.assert_provider_contract() coverage for every advertised capability.
  8. Update .env.example, provider docs, generated catalog surfaces, README, changelog, AGENTS.md, or CLAUDE.md only when public behavior or…
  9. Validate with focused provider tests, ruff, generated provider-doc check, and the coverage/package gates when the public surface changes.

What it can do on your machine

Read from SKILL.md and the folder at commit 30b65da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Provider Adapter Development loads about 990 tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 400 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~89
When it runs · the whole SKILL.md, loaded when a task matches
~990

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:55

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use for WorldForge provider work: adding adapters, changing capability declarations, promoting scaffolds, debugging provider failures, updating provider catalog docs, or touching LeWorldModel, GR00T, LeRobot, Cosmos-Policy, JEPA, Genie, or JEPA-WMS. Ensures capabilities remain truthful and optional runtimes stay host-owned.

Provider Adapter Development

Non-Negotiables

  • Valid capabilities are predict, embed, plan, score, and policy.
  • ProviderCapabilities() is fail-closed. Advertise only callable, tested operations.
  • plan is a WorldForge facade workflow. Do not benchmark or advertise it as a provider operation unless a real provider-owned planner exists.
  • Optional runtimes, checkpoints, datasets, CUDA, robot packages, credentials, and robot controllers stay out of base dependencies and repo artifacts.
  • Provider events are a log boundary. Never emit bearer tokens, API keys, signed URL query strings, or secret-like metadata.
  • Treat upstream marketing names as untrusted. Capability labels come from observed callable behavior and contract tests, not from model family branding.

Workflow

  1. Read the closest existing adapter, then src/worldforge/providers/base.py, src/worldforge/providers/catalog.py, and docs/src/provider-authoring-guide.md.
  2. Classify the upstream runtime by what it actually does, not by model marketing language.
  3. For a new scaffold, start with uv run python scripts/scaffold_provider.py ...; keep capabilities unadvertised until real methods return validated WorldForge models.
  4. Validate public inputs before network calls, filesystem reads, or optional runtime calls.
  5. Return the correct public model: PredictionPayload, EmbeddingResult, ActionScoreResult, or ActionPolicyResult.
  6. Add success and malformed/error fixtures under tests/fixtures/providers/.
  7. Add worldforge.testing.assert_provider_contract() coverage for every advertised capability.
  8. Update .env.example, provider docs, generated catalog surfaces, README, changelog, AGENTS.md, or CLAUDE.md only when public behavior or env vars change.
  9. Validate with focused provider tests, ruff, generated provider-doc check, and the coverage/package gates when the public surface changes.

Definition Of Done

  • Every advertised capability has a provider-contract test and at least one malformed/provider-error test.
  • Provider metadata, docs, generated catalog output, and .env.example agree on capabilities and configuration.
  • Events and public errors redact credentials, signed URLs, host-local secrets, and unsafe metadata.
  • Optional-runtime paths degrade to typed skipped/preflight results without installing host-owned packages.
