Fathom SDK Patterns

What it does

When your agent uses it

• Building reusable Fathom clients
• Implementing meeting data pipelines
• Wrapping the Fathom REST API
• With phrases like fathom API patterns

Example prompts

• “fathom API patterns”
• “fathom client wrapper”
• “fathom Python client”
• “/fathom-sdk-patterns”

Requirements

• Python 3
• A credential in FATHOM_API_KEY
• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit

Workflow steps

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

1. 1Inject credentials only from the approved secret manager and validate request/response contracts at the boundary.
2. 2Use stable IDs, bounded retries, and redacted telemetry for sync/follow-up actions.
3. 3Unit-test with mocks and run one synthetic development integration check before promotion.

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Read
  • Write
  • Edit

  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 python and typescript).

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.fathom.ai

  Also links to:

  • developers.fathom.ai

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

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • FATHOM_API_KEY

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

• Compatibility

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Fathom SDK Patterns loads about 1.1k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 169 words of instructions outside code blocks.

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

~80

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

~1.1k

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

Production-ready Fathom API client patterns in Python and TypeScript. Use when building reusable Fathom clients, implementing meeting data pipelines, or wrapping the Fathom REST API. Trigger with phrases like "fathom API patterns", "fathom client wrapper", "fathom Python client", "fathom TypeScript".
