seedit: Skill for Claude Code

.claude/skills/you-might-not-need-an-effect/SKILL.md

you-might-not-need-an-effect is a skill for Claude Code from bitsocialnet/seedit. It costs 54 tokens per session (1,099 once invoked), scanned A, original, GPL-3.0.

A code-review guide for finding unnecessary or misused React useEffect calls. useEffect is a React feature for running code in response to changes.

In plain words
What is it for?
Use it to audit React components for useEffect anti-patterns and refactor them into simpler alternatives.
Why use it?
It helps replace effects that add complexity when simpler React patterns can produce the same result.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter.

This is bitsocialnet/seedit's own configuration. It tells Claude Code how to work on seedit 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 seedit configures →

SkillSpector: 1 finding, up to high

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 →

  • high Memory Poisoning · line 71
    Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
    Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

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

you-might-not-need-an-effect 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 5d 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 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.
