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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 381 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00024 | $0.05744 |
| Opus 5 | $0.00012 | $0.02872 |
| Sonnet 5 | $0.00005 | $0.01149 |
| Haiku 4.5 | $0.00002 | $0.00574 |
Grade A, and why
sk-create-command 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.
How it starts
The opening of the file, as written. The whole thing — 481 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Command
create-command is the command-authoring workflow packet of the sk-doc parent hub. It creates and improves OpenCode slash commands under .opencode/commands/ with executable workflows, precise frontmatter, required input gates, least-privilege tools, and router/presentation separation when needed.
This SKILL.md contains the core creation workflow. Use the references/ route map (references/README.md), assets/command-template.md, assets/command-router-template.md, assets/command-presentation-template.md, and ../shared/ only for exhaustive examples, edge cases, and validator implementation detail.
This packet is lean and self-contained. The advisor identity lives at the sk-doc hub root; do not add packet-local graph-metadata.json.
1. WHEN TO USE
Activation Triggers
Use this packet when the request involves:
- Creating a new OpenCode slash command.
- Refactoring a command into a thin router plus owned presentation asset.
- Adding or fixing command frontmatter, especially
argument-hintandallowed-tools. - Designing command argument handling with
$ARGUMENTS. - Authoring a namespace command such as
/namespace:action. - Separating visible prompts, dashboards, result templates, or next-step wording into a presentation contract.
- Checking whether a workflow should be a command instead of a skill, agent, or one-off task.
Keyword triggers: create command, /create:command, slash command, OpenCode command, argument-hint, allowed-tools, command template, router presentation split, thin router, presentation contract, paired /create, $ARGUMENTS.
When NOT to Use
Use another sk-doc packet when:
- The request is to create a skill or parent hub. Use
create-skill. - The request is to create an agent. Use
create-agent. - The task is a README, install guide, feature catalog, manual testing playbook, benchmark package, flowchart, or changelog. Use
create-readme,create-feature-catalog,create-manual-testing-playbook,create-benchmark,create-flowchart, orcreate-changelog. - The task audits, validates, scores, or optimizes an existing command document. Use
create-quality-control. - The task is one-time work that does not need a reusable slash command.
- The command already exists and the user only wants runtime debugging.
- The requested workflow is destructive or externally privileged but lacks confirmation and rollback requirements.

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-create-command is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (35 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 5,744 once invoked, about $0.0001 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.
