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

Create Cowork Plugin Package 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 7d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Cowork Plugin Package

Inputs

  • {{name}}: Cowork plugin name
  • {{capability}}: Business capability the plugin supports
  • {{skills}}: Specialized skills to bundle, or none for a connector-only package
  • {{connector}}: MCP connector requirement, or none
  • {{outputDir}}: Package output directory

Requirements

  1. Read .github/skills/development/cowork-plugin-creator/SKILL.md in full before authoring files.
  2. Decompose {{capability}} into non-overlapping skills. Each skill owns one stage, task, or domain and defers explicitly at its boundaries. The package must declare at least one skill or at least one connector.
  3. Create {{outputDir}}/<plugin-name>/manifest.json with manifestVersion, a stable GUID id, version, developer, name, description, icons, agentSkills, and any agentConnectors. Do not add fields outside the supported schema.
  4. Add color.png at 192x192 pixels and outline.png at 32x32 pixels, and reference both from icons.
  5. Create skills/<skill-name>/SKILL.md for every skill. The frontmatter name must be kebab-case and match its folder name exactly, and the description must contain realistic trigger phrases.
  6. Register every skill folder in agentSkills. Populate references/ and scripts/ inside a skill folder only when that skill needs them.
  7. When {{connector}} is not none, add an agentConnectors entry with an HTTPS mcpServerUrl, a packaged mcpToolDescription file under tools/, and an authorization block whose type is None, OAuthPluginVault, ApiKeyPluginVault, or DynamicClientRegistration. Every type except None requires a vault referenceId. Never embed credentials in the package.
  8. Do not leave TODO markers, generic placeholders, secrets, personal data, customer-sensitive data, or unsupported claims.
  9. Require human review before sending, publishing, deleting, approving, or taking another consequential action.
  10. Run .github/skills/development/cowork-plugin-creator/scripts/New-CoworkPluginPackage.ps1 against the completed source directory.
  11. Verify the zip contains manifest.json, both icons, and every registered skill folder at the archive root with no wrapper directory.
  12. Return the generated zip path and a concise list of packaged files. The final deliverable must be the zip file, not only a Markdown response or source directory.

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.
