sk-code

sk-code is a skill for Claude Code from MichelKerkmeester/skilled-agent-harness_spec-driven-loops. It costs 29 tokens per session (3,789 once invoked), scanned A, original, MIT.

A routing skill for coding work that combines quality checks, code review, and project-specific guidance for Webflow, OpenCode, Pi Remote, and Obsidian codebases. It detects the relevant project surface and programming language before applying its workflow.

In plain words
What is it for?
Use it for code-family tasks such as implementing features, reviewing changes, debugging, and running project-specific quality checks.
Why use it?
It helps an agent use the right implementation, debugging, review, and verification rules for the code it is changing.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions OpenCode.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node .skilled/bin/compiled-route.cjs --hub sk-code --prompt "<task>".

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

sk-code 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 today.

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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Canonical source: .skilled/skills/sk-code/. This is a generated markdown-only copy so Hermes can load the skill without scanning the canonical directory. Read references/, assets/ and scripts/ from the canonical path above.

Code Family Hub (sk-code)

One skill, two axes, one shared surface-detection router, and one advisor identity. The workflow axis is two code modes that act (sk-code-quality, sk-code-review). The surface axis is two read-only evidence packets the hub bundles alongside a workflow mode (sk-code-ci, sk-code-skilled). Each carries the shared implement → debug → verify workflow doctrine (shared/references/workflow-*.md, symlinked in) plus its own domain knowledge. This hub holds NO per-mode logic: it routes by workflowMode through mode-registry.json, and each mode or surface keeps its own contract in its packet.

Version authority. This file's version frontmatter is the hub's release version and matches the newest entry under changelog/. description.json, mode-registry.json and hub-router.json carry the same value, so every hub-root JSON routing file states the same release. ROUTER.md and README.md keep their own document versions, as the frontmatter-versioning standard gives every doc but SKILL.md. The authority stops at the hub root: each modes[] packet carries its own version and release cadence, so a packet version is independent of this one by design and a gap between them is not drift.

1. WHEN TO USE

Use this skill for code-family workflows. Invoke it as sk-code with an optional mode hint such as quality: <request>. The hub classifies the request, resolves a mode key, and loads the matching nested packet.

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.
