kubed 2.4.1

Reduce AI agent token usage: layout.json + learned.json replace heavy discovery. Infra index for K8s, Docker, Terraform, Helm.

Kubed

Reduce AI agent token usage with two small files.

CLI and context tooling for Kubernetes, Docker, Terraform, and Helm. Kubed gives AI agents two lightweight files instead of expensive discovery:

File	What it stores	Size
.kubed/layout.json	Infra layout: Dockerfiles, Terraform, Helm, K8s, project structure, shared infra	~1,500–3,000 tokens
.kubed/learned.json	Accumulated knowledge: architecture facts, important paths, dependencies, patterns	~500 tokens

Without Kubed: Agents run find, ls -laR, kubectl get, grep -r → 50,000+ tokens, 10+ tool calls, repeated every session.

With Kubed: Agents read two files → ~2,000–3,500 tokens, 1–2 file reads, knowledge persists across sessions.

• Docs: cmds.daleyarborough.com
• Layout index: kubed layout capture writes .kubed/layout.json. Schema: docs/LAYOUT_SCHEMA.md.
• Learned cache: kubed learned add-fact "..." persists discoveries. Agents read it first to avoid re-discovering.
• Reducing tokens: docs/reducing-token-usage.md

Installation (Python package)

pip install kubed
kubed-setup

Non-interactive: kubed-setup --force-yes. See cmds.daleyarborough.com for full docs.

Layout commands (Go binary)

Build the binary (requires Go 1.21+):

make build   # outputs build/kubed
# or: go build -o build/kubed ./cmd/kubed

• kubed layout capture — Index infra paths, project structure, shared infra, and (optionally) K8s resources; write .kubed/layout.json. Optional: --all-namespaces.
• kubed layout show — Print layout.json to stdout.

Learned cache (accumulated knowledge)

• kubed learned show — Print .kubed/learned.json (facts, paths, deps, patterns accumulated across sessions).
• kubed learned summary — Quick summary: "3 facts, 2 paths, 5 deps, 1 patterns".
• kubed learned add-fact "fact" [--category=X] [--source=Y] — Add a discovered fact.
• kubed learned add-path "/path" "description" [--tags=a,b] — Add an important path.
• kubed learned add-dep "name" [--kind=X] [--version=Y] — Add a dependency.

Agents read learned.json first to avoid re-discovering the same things. When the agent learns something useful (architecture, dependencies, patterns), it persists it so future sessions benefit.

This repo does not use Kubernetes; we validate layout with make test (fixture-based agent-query tests).

Development: test before pushing

Run make verify before pushing to main (same idea as Kubernetes: only working, quality code).

make verify   # runs go vet + tests (unit + agent-query tests)
make test     # tests only
make build    # build binary
make help     # list targets

Tests include agent-query tests: given a layout fixture, they assert that the data passed to an agent/LLM answers questions like "what workloads exist?", "what does service X select?", "what configmaps does deployment Y use?". See internal/layout/query_test.go.
