When your agent uses it
- Working in a Ruby project - provides authoritative sources for documentation
Example prompts
- “/ruby-resource-map”
What it can do on your machine
Read from SKILL.md and the folder at commit b1ea8b5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
docs.ruby-lang.orggithub.comrubyreferences.github.iorailsatscale.comstdgems.orgdocs.seattlerb.orgtest-unit.github.iosorbet.org
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ruby Resource Map loads about 744 tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 235 words of instructions outside code blocks.
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
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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.

Typing Ecosystem
Two type definition formats exist in Ruby:
- RBI - Sorbet's format. Uses Ruby DSL syntax (
sig { ... }) in.rband.rbifiles. - RBS - Official Ruby format (Ruby 3.0+). Dedicated syntax in
.rbsfiles or inline as comments.
Sorbet Ecosystem
Sorbet is a static and runtime type checker for Ruby, maintained by Stripe. Key companion tools:
- Tapioca - Generates RBI files for gems and DSLs (Rails, ActiveRecord, etc.)
- Spoom - Coverage analysis, strictness bumping, dead code detection, signature migration
RBS Ecosystem
- rbs - Official CLI for working with RBS files (prototype, list, methods)
- Steep - Type checker that uses RBS
RBS Inline Comments
Sorbet supports RBS-style inline type annotations using #: comment syntax. This eliminates the need for separate .rbi files or verbose sig blocks.
