kotlin-lib-mcp: Skill for Claude Code

.claude/skills/review-currency/SKILL.md

review-currency is a skill for Claude Code from aoreshkov/kotlin-lib-mcp. It costs 95 tokens per session (914 once invoked), scanned A, original, Apache-2.0.

A review workflow for checking whether the Kotlin library project keeps up with current official releases and recommended practices. It uses specialist reviewers for Kotlin, MCP, dependencies, CI, publishing, security, and setup.

In plain words
What is it for?
Use it to audit version pins, Gradle and GitHub Actions settings, Docker and publishing setup, security controls, and Claude Code configuration.
Why use it?
It replaces guesswork about whether tools, dependencies, workflows, and security practices are out of date. It also requires claims about current versions to be checked against official sources.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is aoreshkov/kotlin-lib-mcp's own configuration. It tells Claude Code how to work on kotlin-lib-mcp 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 kotlin-lib-mcp 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

review-currency 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project currency review — expert panel

Run a currency review of this repository: how far its toolchain, dependencies, and practices have drifted from the latest official releases and recommendations as of today's date. Never judge currency from memory — every claim about "latest" must be verified by the expert subagents against official sources on the web today.

Workflow

1. Snapshot project state

Read these files and collect the facts the experts will need (versions, pins, action refs, base images). Note today's date — all research anchors to it.

  • gradle/libs.versions.toml — every version pin and its comments (comments mark deliberate pins)
  • gradle/wrapper/gradle-wrapper.properties — Gradle version
  • .github/workflows/ci.yml, .github/workflows/codeql.yml, .github/workflows/release.yml
  • Dockerfile and server.json
  • CLAUDE.md — project conventions and gotchas the experts must honor
  • .claude/ — agents, skills, hooks, settings.json (the Claude Code setup itself)

2. Select the panel

The panel is six dedicated currency subagents (defined in .claude/agents/): kotlin-currency, mcp-currency, deps-currency, ci-currency, security-currency, claude-code-currency. Each agent carries its own persona, inspection list, official sources, project gotchas, and output contract — they are the single source of truth. (references/experts.md is the human-readable copy of those briefs, kept in sync for reviewers.)

If $ARGUMENTS is non-empty, launch only the experts whose keys it names (kotlin, mcp, deps, ci, security, claude-code → the matching *-currency agent); otherwise launch all six.

3. Launch the experts in parallel

Launch one subagent per selected expert, all in a single message, using the matching *-currency agent type. Each agent already knows its brief and output contract, so the prompt only needs to supply:

  1. The relevant snapshot facts from step 1 (versions, pins, action refs, base images).
  2. The absolute repo path and today's date.
  3. A reminder to return the standard findings table (Area | Current in repo | Latest official | Severity | Recommendation | Source URL) followed by ≤5 sentences of practice-level commentary — the agent's own definition spells this out in full.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
