Repository instructions for developing a Home Assistant integration that exposes Home Assistant through an MCP server. They explain which internal APIs are safe to call and when to use a service instead.

Use them when changing handlers, replacing private calls with Home Assistant services, or checking whether a method is a supported entity interface, a cross-integration internal, or an unsupported data lookup.

They help prevent integration code from depending on private Home Assistant internals that may change without warning. They also highlight that service calls can return fewer fields than the methods they replace.

pulumi-esc — Skill for Claude Code and Codex by pulumi

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add pulumi/agent-skills --skill pulumi-esc

Clone the repo

git clone --depth 1 https://github.com/pulumi/agent-skills

Made for: Claude Code, Codex.

Or install pulumi, the plugin that ships this one along with the rest of its 9 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.02839
Opus 5	$0.00039	$0.01419
Sonnet 5	$0.00016	$0.00568
Haiku 4.5	$0.00008	$0.00284

Security

Grade A, and why

pulumi-esc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Pulumi ESC (Environments, Secrets, and Configuration)

Pulumi ESC is a centralized service for managing environments, secrets, and configuration across cloud infrastructure and applications.

What is ESC?

ESC enables teams to:

Centralize secrets and configuration in one secure location
Compose environments by importing and layering configuration
Generate dynamic credentials via OIDC for AWS, Azure, GCP
Integrate external secret stores (AWS Secrets Manager, Azure Key Vault, Vault, 1Password)
Version and audit all configuration changes
Control access with fine-grained RBAC

Essential CLI Commands

# Create a new environment
pulumi env init <org>/<project-name>/<environment-name>

# Edit environment (opens in editor)
pulumi env edit <org>/<project-name>/<environment-name>

# Set values
pulumi env set <org>/<project-name>/<environment-name> <key> <value>
pulumi env set <org>/<project-name>/<environment-name> <key> <value> --secret

# View definition (secrets hidden)
pulumi env get <org>/<project-name>/<environment-name>

# Open and resolve (reveals secrets)
pulumi env open <org>/<project-name>/<environment-name>

# Run command with environment
pulumi env run <org>/<project-name>/<environment-name> -- <command>

# Link to Pulumi stack
pulumi config env add <project-name>/<environment-name>

Key Concepts

Command Distinctions

pulumi env get: Shows static definition, secrets appear as [secret]
pulumi env open: Resolves and reveals all values including secrets and dynamic credentials
pulumi env run: Executes commands with environment variables loaded
pulumi config env add: Only takes the / portion

Environment Structure

Environments are YAML documents with reserved top-level keys:

imports: Import and compose other environments
values: Define configuration and secrets

Reserved sub-keys under values:

environmentVariables: Map values to shell environment variables
pulumiConfig: Configure Pulumi stack settings
files: Generate files with environment data

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
