marketing-clis: Skill for Claude Code

.claude/skills/generate-cli/SKILL.md

generate-cli is a skill for Claude Code from FunnelEnvy/marketing-clis. It costs 26 tokens per session (1,058 once invoked), scanned A, original, MIT.

A skill for generating a complete command-line program for a marketing platform from its REST API documentation. A command-line program is a tool operated through a terminal rather than a graphical interface.

In plain words
What is it for?
Use it when adding a CLI for a platform such as HubSpot or SendGrid: provide the tool name and API documentation URL, then follow the repository's generation workflow.
Why use it?
It removes much of the repeated work involved in studying an API, choosing supported operations, and creating a consistent CLI project.

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.

Security

Grade A, and why

generate-cli 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 2mo ago.

The scan reads SKILL.md. This mod also ships 7 executable files (templates/node-cli/src/auth.ts, templates/node-cli/src/index.ts, templates/node-cli/src/lib/config.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Generate a Marketing CLI

Generate a complete CLI tool for a marketing platform from its API documentation.

Usage

/generate-cli <tool-name> <api-docs-url>

Examples:

/generate-cli hubspot https://developers.hubspot.com/docs/api/overview
/generate-cli sendgrid https://docs.sendgrid.com/api-reference

Arguments

The user must provide:

  • tool-name — lowercase name for the CLI (e.g., hubspot, sendgrid). Becomes the binary name, repo name ({tool}-cli), and npm package (@funnelenvy/{tool}-cli).
  • api-docs-url — URL to the platform's REST API documentation.

If either is missing, ask for it before proceeding.

Workflow

Follow all four phases in order. Read CLAUDE.md at the repo root for the full standards — it is the source of truth for naming, auth patterns, output formatting, error handling, and file structure.

Phase 1: API Discovery

  1. Fetch and read the API docs at the provided URL
  2. Check for an OpenAPI/Swagger spec (/openapi.json, /swagger.json)
  3. If a spec exists, save it as api-spec.json in the CLI repo
  4. Build an endpoint inventory:
    • Group endpoints by resource (campaigns, contacts, reports, etc.)
    • Note the auth method (API key, OAuth2, both)
    • Note rate limits and pagination patterns
    • Note response envelope format
  5. Save the inventory as api-inventory.md in the CLI repo

Reference: prompts/api-discovery.md

Phase 2: CLI Design

  1. Map API resources to command groups (nouns): campaigns, lists, reports
  2. Map CRUD operations to subcommands (verbs): list, get, create, update, delete
  3. Design the auth flow: --api-key flag > env var > config file > interactive login
  4. Plan output: JSON (default), table, CSV for all data commands
  5. Write the command tree and present it to the user before writing code
  6. Prioritize the most-used endpoints — don't try to cover every endpoint

Reference: prompts/cli-design.md, generator/prompts/auth-patterns.md

Phase 3: Scaffold & Implement

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.
