Memoh: Skill for Claude Code

.agents/skills/memoh-error-handling/SKILL.md

memoh-error-handling is a skill for Claude Code, Codex from felinics/Memoh. It costs 92 tokens per session (2,394 once invoked), scanned A, original, AGPL-3.0.

A shared error-handling approach for the Memoh application, covering backend errors, server-sent events, and frontend error codes. Server-sent events are a way to send ongoing updates from a server to a browser.

In plain words
What is it for?
Adding user-facing backend errors, formatting error responses, handling streaming updates, and letting the frontend choose localized messages.
Why use it?
It keeps application logic based on stable error codes while preventing private diagnostic details from being sent to users.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

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

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is go test ./internal/apperror/... ./internal/server/... ./internal/handlers/....

About the project

Memoh is an open-source multi-agent platform that gives each AI agent a persistent computer-like workspace with a filesystem, desktop, browser, network access, and long-term memory. It is for individuals and teams running agents continuously, including built-in agents or coding agents such as Claude Code and Codex, through chat platforms and a web interface.

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 →

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

memoh-error-handling scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.
