Cue Kind Definition

What it does

When your agent uses it

• Working with CUE kinds
• Adding a new resource type
• Adding a version to an existing kind
• Writing schema field constraints

Example prompts

• “model a resource”
• “add a CUE schema”
• “write a kind”
• “/cue-kind-definition”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1Common kind metadata
2. 2Per-version schema
3. 3App manifest

What it can do on your machine

Read from SKILL.md and the folder at commit 1ccacf2. 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

  No scripts in the folder and no shell commands in SKILL.md (its code samples are cue and bash).

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

• Network

  Links to these hosts (documentation or services it may open):

  • github.com
  • cuelang.org

  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

Cue Kind Definition loads about 1.4k tokens when it runs, and up to ~7.4k if it reads all its reference files. Until then it costs about 202 tokens; SKILL.md has 230 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~202

When it runs · the whole SKILL.md, loaded when a task matches

~1.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~7.4k

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

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

Author CUE kind definitions for grafana-app-sdk apps - schemas, versioning, field constraints, named type definitions, custom routes, and codegen configuration. Scaffolds kinds via `grafana-app-sdk project kind add`, writes spec/status schemas with type constraints (regex, enum, range), defines `#`-prefixed named types for reusable structs, registers versions in the app manifest, and runs `grafana-app-sdk generate` with explicit error recovery. Use when working with CUE kinds, adding a new resource type, adding a version to an existing kind, writing schema field constraints, defining `#Definition` types, adding custom routes, editing files under `kinds/`, or when the user asks to "model a resource", "add a CUE schema", or "write a kind" — even without saying "CUE" explicitly.

# 1. Scaffold the kind files
grafana-app-sdk project kind add MyKind --overwrite
# Produces kinds/mykind.cue + kinds/mykind_v1alpha1.cue + updates kinds/manifest.cue.

# 2. Edit the generated .cue files — fill in schema.spec / schema.status fields

# 3. Generate types and clients
grafana-app-sdk generate

# 4. Verify the generated artifacts exist
ls pkg/generated/    # should contain new types for MyKind

# 1. Copy the existing version file
cp kinds/mykind_v1alpha1.cue kinds/mykind_v1.cue

# 2. Edit kinds/mykind_v1.cue — rename the top-level object (e.g. myKindv1) and adjust the schema

# 3. Register the new version in kinds/manifest.cue
#    Add a versions["v1"]: { schema: myKindv1 } entry

# 4. Re-generate
grafana-app-sdk generate

# 5. Verify both versions were generated — per-version Go types live under pkg/generated/<group>/<version>/
ls pkg/generated/             # should list both version directories (e.g. v1alpha1/ v1/)
# Optionally inspect the CRD spec under definitions/ to confirm both versions appear in `spec.versions[]`
