yorishiro-proxy: Skill for Claude Code

.claude/skills/implement/SKILL.md

implement is a skill for Claude Code from usk6666/yorishiro-proxy. It costs 22 tokens per session (1,349 once invoked), scanned A, original, Apache-2.0.

An end-to-end workflow for implementing a Linear Issue, which is a tracked development task, from selecting a branch through testing, committing, and opening a pull request.

In plain words
What is it for?
Loading and updating issues, creating branches, reviewing designs, presenting an implementation plan, writing code, testing it, committing changes, and creating a pull request.
Why use it?
It keeps the work connected to its issue and applies the same implementation steps each time, including a required design review for broader changes.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is usk6666/yorishiro-proxy's own configuration. It tells Claude Code how to work on yorishiro-proxy 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 yorishiro-proxy 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

implement 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 13d 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.

/implement

An end-to-end workflow skill for implementing a Linear Issue through to PR creation.

Arguments

  • /implement <Issue ID> — Implement the specified Issue (e.g., /implement USK-12)

Steps

  1. Load Issue: Fetch Issue details with mcp__linear-server__get_issue
  2. Update Issue status: Update status to "In Progress"
  3. Create branch: Generate an appropriate branch name from the Issue
    • feat: feat/<id>-<short-desc>
    • fix: fix/<id>-<short-desc>
    • other: chore/<id>-<short-desc>
  4. Design review (mandatory for any Issue that introduces a new public type, modifies an interface, or touches more than one package; skip for docstring-only / test-only / single-call-site fixes — note the skip reason in the user-facing plan): launch the design-reviewer agent. See "Design Review Invocation" below.
  5. Present plan to user: Issue summary, file actions (new / modified / untouched), key resolved decisions from the design review, the Test Plan (the failing tests that will be written first), deferred items, unresolved questions. Get user confirmation before implementing. For trivial Issues that skipped Step 4, present a one-paragraph plan that still names the failing test(s) to write first, or the TDD exemption that applies.
  6. Red — write failing tests first: Follow "TDD Workflow" Phase 1 in .claude/agents/implementer.md (it is the single source for the rules and exemptions). Write the tests plus compile-only scaffolding, run them with make test-pkg PKG=<pkg> RUN=<regexp>, confirm each fails on its assertion (not a compile error or no tests to run), and commit them alone as test(<scope>): add failing tests for <Issue ID>. Keep the --- FAIL: lines for the PR body.
  7. Green, then refactor: Implement until the Phase 1 tests pass, without weakening any Phase 1 assertion (implementer.md Phase 2), then refactor.
  8. Verify:
    • Auto-format with gofmt -w .
    • make lint (gofmt check + golangci-lint: govet / staticcheck / unused / ineffassign / gocyclo)
    • make build
    • make test
  9. Commit: Commit in Conventional Commits format, as a separate commit after the Step 6 red commit (do not amend or squash them together)
    • Include Refs: <Issue ID> in the commit message footer
  10. Push: Push to remote with git push -u origin <branch-name>
  11. Create PR:
    • Review changes with git diff main...HEAD
    • PR title in Conventional Commits format (e.g., feat(protocol): add HTTP handler)
    • PR body follows the template below
    • Create PR with gh pr create
  12. Update Issue status: Update status to "In Review"
  13. Report results: Display implementation summary + PR URL

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.

implement is a skill published in the GitHub repository usk6666/yorishiro-proxy (19 stars, last pushed yesterday), licensed Apache-2.0. It adds 22 tokens to every session and 1,349 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
