Claude Code mod
snagon-dev-mods
A coding-agent harness for Claude Code as a mod that needs only Claude Code: /snagon-setup writes your project instructions without repeating the harness, a per-project memory (SQLite full-text search over JSONL, kept out of git), a fact-forcing safety gate with git hook-bypass and secret checks, session journal reminders, end-of-session handoff, cost and context notices, a flow that takes TypeScript and Python features from plan to release under the owner's approvals (tickets, tests first, a sandboxed judge, review, verify, ship), plus 64 skills, 66 agents and 43 commands.

How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

More memory & instructions mods
session-handoff
1m-tababi/session-handoff
Writes a structured session handoff on demand to ~/.claude/handoffs/<project>/ (never into the project), resumes from the newest one, restarts into a fresh conversation with the handoff (pill or /handoff fresh) and hints once when the context fills up.
style-cop
1MDmubarak786/claude-mods
Enforce the style rules Claude keeps ignoring: banned words and phrases, a comment-density cap on added code, and files that must not gain comments. Rules live in .claude/style-cop.md and are both shown to Claude and enforced on edits.
segmem
1mahuebel/segmem
Segmented, scoped memory for agents: one file, SQLite, no daemon. Wake at session start, recall on every prompt, staleness nag at stop.
walkthrough
1enhki/claude-mods
A checklist pane for manual testing: Claude publishes the steps, you mark each pass, fail or skip with a note, and the results go back as one message
neo4j-memory
1troglodyte/claude-sqlite-mem
Persistent memory for Claude Code in a local SQLite file (node:sqlite; no server, no container). Injects standing facts and a subsystem map at session start, captures new facts at compaction and session end, and exposes search tools. A machine's Neo4j graph moves across by itself on first start.
