eventyay: Skill for Claude Code

.agents/skills/plugin-integration/SKILL.md

plugin-integration is a skill for Claude Code, Codex from fossasia/eventyay. It costs 29 tokens per session (268 once invoked), scanned A, original, Apache-2.0.

An integration workflow for Eventyay core and its Business and Stripe plugin repositories. It traces shared events or API contracts between the core system and the plugins, then checks the changes across the affected repositories.

In plain words
What is it for?
Use it to set up local plugin integration, trace event receivers, test changed contracts, prepare coordinated pull requests, and handle compatible entry points or webhook aliases.
Why use it?
It helps prevent mismatches when a shared contract changes in one repository but not its consumers. It also checks duplicate or failed delivery and keeps core behavior separate from payment-specific behavior.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fossasia/eventyay's own configuration. It tells Claude Code and Codex how to work on eventyay itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything eventyay configures →

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

plugin-integration 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 8d 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.

What it actually says

Plugin integration

Read the repository map to identify the owner of the behavior, then setup and delivery when installing, testing, or preparing a release. Follow root agents.md and the matching .github/instructions/ rules.

  1. Confirm Git roots, branches, and installed module paths before editing. A plugin directory and the package currently imported by Python may differ.
  2. Trace the relevant shared signal/API and its plugin receiver. Check behavior with no receiver and with duplicate/failed delivery where relevant.
  3. Keep core contracts in core and commercial/payment implementations in their owning repository. Preserve compatible entry-point names and webhook aliases.
  4. Test the changed contract in core and affected consumers in their repository. Use the review guide for fee/billing changes.
  5. Prepare separate PRs against dev, recording revisions and compatibility. Use the handoff template; coordinate lock updates only when a released code change needs them.
Files

What ships with it

2 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.
