toml

toml is a skill for Claude Code, Codex from jscraik/Agent-Skills. It costs 29 tokens per session (642 once invoked), scanned A, original, Apache-2.0.

A guide for creating and reviewing TOML configuration files, a text format commonly used for tool settings. It focuses on correct types, expected keys, compatibility, and preserving a file’s structure.

In plain words
What is it for?
Use it to create or repair TOML settings, check them against a tool’s schema, preserve comments and key order, and validate the result.
Why use it?
It helps prevent configuration files that parse incorrectly or use keys and value types the owning tool does not understand. It keeps fixes small and easier to review.

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

toml 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 8d 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.

Table of Contents

When to use

  • Use for TOML config creation, review, or schema-safe fixes.
  • Inputs: target files, owning tool, expected key paths, and compatibility constraints.
  • Deliver valid TOML with minimal key-path churn and notes for schema-impacting edits.

Required inputs

  • Target TOML file path and owning tool or schema.
  • Intended key paths, value types, and compatibility constraints.
  • Validation command or parser expected to consume the file.

Deliverables

  • Minimal TOML edit preserving existing comments and order where possible.
  • Validation evidence from parser, schema, or owning tool.
  • Notes for any type, key-path, or compatibility risk.

Philosophy

  • Prefer schema truth and low-churn edits over clever rewrites.

Procedure

  1. Confirm the consumer schema and current key paths.
  2. Make the smallest compatible edit.
  3. Validate before closeout.

TOML Guidelines

  • Preserve key order where tool owners expect readability.
  • Prefer explicit scalars and arrays over ambiguous shapes.
  • Keep one responsibility per table and use dotted keys consistently.
  • Do not mix inline tables and expanded tables for the same object path.

Editing Rules

  • Change only the smallest required key path.
  • Retain existing comments unless provably outdated.
  • Keep trailing commas out of arrays and inline tables.

Validation

  • Run the relevant parser/schema/tool checks for touched files.
  • Fail fast: stop at the first failed gate and report exact blocker evidence.

Constraints

  • If schema ownership is unclear, pause before adding keys.
  • Redact secrets and do not run destructive or network commands unless explicitly approved.

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.
