Add New OPC Skill

Use this skill when adding a new skill to the OPC Skills project. Follow every step below to ensure the skill meets all publishing requirements.

Pre-flight

Before starting, confirm:

You are on a feature branch: feature/skill/<skill-name> (branched from develop)
The skill name is kebab-case (e.g., my-new-skill)

Checklist

1. Skill Directory Structure

Create the skill directory with required files:

skills/<skill-name>/
├── SKILL.md              (required) Main skill documentation
├── scripts/              (if skill has scripts)
│   └── *.py / *.sh
├── examples/             (recommended) Usage examples
│   └── *.md
└── references/           (optional) API docs, templates
    └── *.md

SKILL.md must include YAML frontmatter:

---
name: <skill-name>
description: Clear description. Include trigger keywords and "Use when..." contexts.
---

Use template/SKILL.md as a starting point:

cp -r template skills/<skill-name>

2. Skill Logo

Generate a pixel-art style SVG logo matching existing skill logos:

# Use the logo-creator skill
python3 skills/nanobanana/scripts/batch_generate.py \
  "Pixel art <subject> logo, 8-bit retro style, black pixels on white background, minimalist icon, clean crisp edges, no text, centered" \
  -n 20 --ratio 1:1 \
  -d .skill-archive/logo-creator/<date>-<skill-name> \
  -p logo

# Open preview to pick a logo
cp skills/logo-creator/templates/preview.html .skill-archive/logo-creator/<date>-<skill-name>/
open .skill-archive/logo-creator/<date>-<skill-name>/preview.html

# After picking (e.g., #5):
python3 skills/logo-creator/scripts/crop_logo.py <input>.png <output>-cropped.png
python3 skills/logo-creator/scripts/vectorize.py <output>-cropped.png skill-logos/<skill-name>.svg

Verify: skill-logos/<skill-name>.svg exists and matches the pixel-art style of other logos.

3. skills.json Entry

4. README.md

Add the skill to the "Included Skills" table in README.md:

| <img src="./skill-logos/<skill-name>.svg" width="24"> | [<skill-name>](./skills/<skill-name>) | Short description |

Insert in the appropriate position within the existing table.

5. Website (worker.js)

Add the skill to the hardcoded skills array in website/worker.js inside the fetchCompareData() function. Find the ],\n };\n} closing of the skills array and add before it:

{
  name: "<skill-name>",
  version: "1.0.0",
  description: "<description>",
  icon: "<icon>",
  color: "<color>",
  triggers: ["trigger1", "trigger2"],
  dependencies: [],
  auth: { required: false, note: "..." },
  install: {
    user: {
      claude: "npx skills add ReScienceLab/opc-skills --skill <skill-name> -a claude",
      droid: "npx skills add ReScienceLab/opc-skills --skill <skill-name> -a droid",
      opencode: "npx skills add ReScienceLab/opc-skills --skill <skill-name> -a opencode",
      codex: "npx skills add ReScienceLab/opc-skills --skill <skill-name> -a codex",
    },
    project: {
      claude: "npx skills add ReScienceLab/opc-skills --skill <skill-name>",
      droid: "npx skills add ReScienceLab/opc-skills --skill <skill-name>",
      cursor: "npx skills add ReScienceLab/opc-skills --skill <skill-name>",
      opencode: "npx skills add ReScienceLab/opc-skills --skill <skill-name>",
      codex: "npx skills add ReScienceLab/opc-skills --skill <skill-name>",
    },
  },
  commands: [],
  links: {
    github: "https://github.com/ReScienceLab/opc-skills/tree/main/skills/<skill-name>",
  },
},

6. CHANGELOG.md

Add the skill to the Skill Compatibility & Dependency Matrix table:

| **<skill-name>** | 1.0.0 | - | - |

Add an entry under ## [Unreleased] (or the release version section):

### <skill-name>
#### [1.0.0] - YYYY-MM-DD
- **Added**: Initial release - <description>

Verification

Before committing, verify all items:

# 1. SKILL.md exists with valid frontmatter
head -5 skills/<skill-name>/SKILL.md

# 2. Logo SVG exists
ls -la skill-logos/<skill-name>.svg

# 3. skills.json is valid JSON with all fields
python3 -c "
import json
config = json.load(open('skills.json'))
skill = [s for s in config['skills'] if s['name'] == '<skill-name>'][0]
required = ['name','version','description','logo','icon','color','triggers','dependencies','auth','install','links']
missing = [f for f in required if f not in skill]
print('PASS' if not missing else f'MISSING: {missing}')
"

# 4. README.md lists the skill
grep '<skill-name>' README.md

Declarative Agents

by github

vendor ×1

Complete development kit for Microsoft 365 Copilot declarative agents with three comprehensive workflows (basic, advanced, validation), TypeSpec support, and Microsoft 365 Agents Toolkit integration

Format and structurally validate local treatment-plan documentation after clinical decisions have already been supplied and verified by authorized licensed professionals. Use for source traceability, clinician-authored intervention records, goals and checkpoints, shared-decision records, reconciliation handoffs, and release gates—not for clinical decision-making.

> provider/change budget/修改卖家/修改预算/draft/草稿/我的任务/my tasks/what am I working on/关闭/取消任务/决策列表/decision list/指定服务商/browse (sender.role = COUNTERPARTY, not you); (3) literal "Read the okx-ai skill" (or legacy "Read the okx-agent-task skill") in the envelope.

Prior Auth Review Skill

by anthropics

vendor ×1

Automate payer review of prior authorization (PA) requests. This skill should be used when users say "Review this PA request", "Process prior authorization for [procedure]", "Assess medical necessity", "Generate PA decision", or when processing clinical documentation for coverage policy validation and authorization decisions.

Expert in designing and building autonomous AI agents. Masters tool use, memory systems, planning strategies, and multi-agent orchestration.

Autonomous agents are AI systems that can independently decompose goals, plan actions, execute tools, and self-correct without constant human guidance. The challenge isn't making them capable - it's making them reliable. Every extra decision multiplies failure probability.

Orchestrates design workflows by routing work through brainstorming, multi-agent review, and execution readiness in the correct order.

Structured persuasion for tech leads, PMs, and founders—not activity logs. Five scenarios (kickoff, status update, wrap-up, investor pitch, solution selling) on one 5-part framework (Hook→Context→Proposal→Evidence→Ask). AI prompts for missing materials and audience context; pre-submit checklist. Claude Code plugin; Cursor, Codex, and chat via prompts.

How to use it

Copy the folder

Take resciencelab/add-new-opc-skill from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
