bike_index: Skill for Claude Code

.claude/skills/rspec-testing/SKILL.md

rspec-testing is a skill for Claude Code from bikeindex/bike_index. It costs 91 tokens per session (3,702 once invoked), scanned A, original, AGPL-3.0.

A guide for writing RSpec tests in the Bike Index Ruby application. RSpec is a Ruby testing tool, and a spec is a test file describing expected behavior.

In plain words
What is it for?
Use it when adding or changing spec files, increasing test coverage, or deciding how to structure tests for Ruby code.
Why use it?
It helps tests follow the project's conventions and avoids test patterns the project does not want, such as mocking certain behavior.

Skill for Claude Code

This is bikeindex/bike_index's own configuration. It tells Claude Code how to work on bike_index itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything bike_index configures →

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

rspec-testing 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 6d 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.

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.
