What it does
Send Private Method is an agent skill from Shopify/rubydex, published by the product's own GitHub organization. Remediate a send/send call that reaches a private method, restoring a real public seam instead of bypassing visibility. Use when send is being used to invoke private functionality in a class.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Ruby. The repository describes itself as: A high-performance static analysis toolkit for Ruby.
When your agent uses it
- Send is being used to invoke private functionality in a class
Example prompts
- “/send-private-method”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Promote to public (or protected)
- Drive the public entry point, assert on the observable outcome
- Extract to its own object/module
What it can do on your machine
Read from SKILL.md and the folder at commit d8ff475. 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 (its code samples are ruby).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Send Private Method loads about 1.8k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 924 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 924 words (~1,848 tokens).
“A test calls obj.send(:some_private_method) (or send) to invoke a method Ruby's visibility system would otherwise forbid. send deliberately bypasses encapsulation. send behaves identically and is the conventional spelling when a class defines its own send; Ruby warns when you redefine…”
