A documentation hub that directs authoring tasks to the right workflow for creating skills, agents, commands, guides, changelogs, and other OpenCode components.

Use it to create or update OpenCode documentation and component files, including skills, agents, READMEs, commands, and catalogs.

It prevents documentation work from being handled by the wrong workflow and provides shared quality checks.

sk-doc — Skill for Claude Code and OpenCode by MichelKerkmeester

Install

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.

Clone the repo

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.03616
Opus 5	$0.00017	$0.01808
Sonnet 5	$0.00007	$0.00723
Haiku 4.5	$0.00003	$0.00362

Security

Grade A, and why

sk-doc 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 yesterday.

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.

Documentation Authoring Hub (sk-doc)

One advisor identity, fourteen workflow modes across thirteen packets, one shared sk-create-quality-control backbone. sk-doc is the parent hub for documentation and OpenCode-component authoring. It holds NO per-packet logic: it routes by workflowMode through mode-registry.json, and each packet keeps its own contract in its nested folder. The cross-cutting sk-create-quality-control pipeline (validators, global standards, frontmatter/llms/template assets) lives once in shared/ and is consumed by every packet.

1. WHEN TO USE

Use this skill for documentation and OpenCode-component authoring, and for document-quality work. The hub classifies the request, resolves a workflowMode, and loads the matching nested packet.

Mode	Use it for	Packet	Command
sk-create-skill	Scaffold an OpenCode skill (and, via `sk-create-skill-parent`, a parent hub with nested mode packets)	`sk-create-skill/`	`/create:skill`, `/create:skill-parent`
sk-create-readme	Author a folder README or an install guide (install-guide is a folded variant)	`sk-create-readme/`	`/create:readme`
sk-create-agent	Scaffold an OpenCode agent (permission/authority frontmatter)	`sk-create-agent/`	`/create:agent`
sk-create-command	Scaffold an OpenCode slash command (argument-hint + allowed-tools + router/presentation split)	`sk-create-command/`	`/create:command`
sk-create-feature-catalog	Author a feature-catalog inventory package	`sk-create-feature-catalog/`	`/create:feature-catalog`
sk-create-manual-testing-playbook	Author a manual-testing-playbook package	`sk-create-manual-testing-playbook/`	`/create:manual-testing-playbook`
sk-create-benchmark	Author MCP-promotion, behavior, skill-benchmark, and model-benchmark packages or inputs	`sk-create-benchmark/`	`/create:benchmark`
sk-create-changelog	Author a global or packet-local changelog entry (version bump + topology-aware placement)	`sk-create-changelog/`	`/create:changelog`
sk-create-diff	Produce a local, Git-free before/after review of an edited document (text/Markdown/HTML/DOCX/text-PDF) as a self-contained HTML report	`sk-create-diff/`	`/create:diff`
sk-create-repo-rule	Create, revise or retire a repo-local rule under `repo-rules/` and wire it into `REPO RULES.md` (four decision tests refuse most requests)	`sk-create-repo-rule/`	`/create:repo-rule`
sk-create-with-human-voice	Apply the Human Voice Rules to prose, or score prose against them, with a scope gate and a re-scan	`sk-create-with-human-voice/`	`/create:with-human-voice`
sk-create-frontmatter	Own the YAML frontmatter contract: per-class field rules, the description budget, and the 4-part `version` derivation	`sk-create-frontmatter/`	— (routes via aliases)
sk-create-quality-control	Validate / score / optimize an EXISTING document (extract → DQI → HVR → validate)	`sk-create-quality-control/`	(routes via aliases)

What ships with it

60 files 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.

sk-doc is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (35 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 3,616 once invoked, about $0.0002 per session on Opus 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 2026-09-03.
