Lody: Skill for Claude Code

.agents/skills/effect-ts/SKILL.md

effect-ts is a skill for Claude Code, Codex from LodyAI/Lody. It costs 30 tokens per session (1,240 once invoked), scanned A, original, Apache-2.0.

A set of instructions for writing, reviewing, debugging, and setting up Effect code in TypeScript. Effect is a TypeScript library for structuring asynchronous work, errors, cancellation, and resource cleanup.

In plain words
What is it for?
Use it when changing Effect-based TypeScript code, checking resource and cancellation behavior, or reviewing related tests and implementation details.
Why use it?
It helps keep code aligned with the repository's locked package versions and local rules instead of relying on a different installed version. It also directs validation toward behavioral tests for cancellation, shutdown, retries, and cleanup.

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

This is LodyAI/Lody's own configuration. It tells Claude Code and Codex how to work on Lody 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 Lody configures →

About the project

Lody is a shared workspace that connects coding agents running on different computers and lets people view and direct their work from desktop, mobile, web, or a command line. Teams use it to share agent conversations, monitor progress and code changes, and assign work to connected machines while retaining their existing agents and configurations.

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

effect-ts 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 21d 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.

Native Effect work in Lody

Use this skill before assessing a native migration, choosing its structure or changing Effect lifecycle behavior. Lody already uses v4; ordinary Promise-to-Effect refactoring does not invoke the v3-to-v4 skill. Use that skill only for an explicitly scoped version migration.

Resolve the reference and scope

Select the task mode before migration planning:

Request Work and stopping condition
Review Trace changed behavior against the base and applicable contracts; report only findings allowed by repository review rules. Do not start a migration.
Debug Reproduce the symptom, isolate the cause and distinguish raw work from its waiter; diagnosis alone does not authorize a rewrite.
Feature/fix Deliver the requested behavior; include a complete native unit only when its dependencies and verification fit the task. Deferring migration is a valid outcome.
Dedicated migration Trace the complete responsibility and consumers; apply all three completion axes: kernel, consumers and ownership.

Keep the workspace catalog and lockfile version. Follow repository installation rules if dependencies are missing; do not install latest, add a root dependency or upgrade packages as a side effect. Resolve Effect from the consuming package, read its effect/AGENTS.md completely once per resolved version in the current context, then follow task-relevant links. Re-read if the version or context is lost. Search that release's ai-docs and src for APIs and lifecycle semantics. Upstream main and a temporary exact-release reference are not local validation.

Read applicable scoped AGENTS.md and relevant sections of Lody's Effect guide. For migration scope or completion claims, consult the relevant charter and ledger rows and their owning Notes; a whole-roadmap reread is unnecessary. Retain existing product contracts, pure computation, public/local boundaries and disabled telemetry. Upstream Schema, SQL and CLI examples do not authorize replacing Lody's existing validation, persistence or command frameworks.

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.

effect-ts is a skill published in the GitHub repository LodyAI/Lody (1,640 stars, last pushed today), licensed Apache-2.0. It adds 30 tokens to every session and 1,240 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-11.
