hundreds of sessions across dozens of projects. $200/mo max plan.
same usage would cost ~$12K on the API with caching, ~$95K without. no autonomous loops. no cron jobs. every session starts with me typing a prompt. how the cost math works →

/plugin install lore@anipotts # install lore (session analytics)
/plugin install cc@anipotts # install cc (cross-session messaging)
/plugin install time@anipotts # install time (fuel gauge + estimates)you get lore · session mining to sqlite. costs, search, error memory, pattern detection. all data stays local at ~/.claude/lore/lore.db.
/lore today's sessions, cost, top tools
/lore search "websocket" full-text search across all conversations
/lore mistakes error patterns claude keeps repeating
/lore hotspots most-edited files across sessions
/lore loops repeated patterns across sessions
start with lore + the safety-guard hook. add more as you go. lore docs →
cross-session messaging and the time subsystem. see what other claude code sessions are doing, send messages between them, and get realistic time estimates grounded in your own session history.
/plugin install cc@anipotts/cc show active sessions
/cc send merizo "pause" message another session
/cc:time-estimate <task> ranged CC estimate, uses your current model + effort
/cc:time-calibrate diff real throughput (from lore.db) against the rule
/cc:time-benchmark guided A/B/C across effort levels on your model
hooks are the difference between "claude does what i want" and "claude does whatever it feels like." CLAUDE.md gives guidance. hooks give enforcement. one is a suggestion, the other is a wall.
this repo has 9 hooks you can drop into any project. safety-guard blocks force pushes, rm -rf /, and curl | bash. no-squash blocks squash merges. context-save preserves state before compaction. pick the ones that fit your workflow. hook guide →
multiple claude instances working simultaneously on the same codebase, each in its own git worktree. the coordinator assigns tasks, collects results, merges the best approach.
i use this for parallel research, trying risky changes safely, and comparing approaches side-by-side without touching my working tree. how i use agent teams →
this is why the $200/mo plan is the best deal in AI coding. claude code caches your system prompt, tools, and CLAUDE.md as a prefix. 91% of my input tokens hit the cache, meaning i pay 10% of the input cost on 91% of my reads.
the key: keep your CLAUDE.md short and stable. every edit breaks the prefix cache. mine is 30 lines and changes maybe once a week. the full cost breakdown →
short, standalone techniques. each one is something you can use in your next session.
| tip | what you learn |
|---|---|
| prompt caching | get 97%+ cache hit rates, slash your bill |
| safety hooks | block force pushes and rm -rf in 5 minutes |
| settings hierarchy | project vs global vs local settings |
| session length | why shorter sessions are more efficient (with data) |
| ultrathink | force extended thinking for complex problems |
| context management | compaction strategies, active tool rate, keeping sessions tight |
| plan mode | when planning saves time vs when it wastes it |
| fast mode | same model, faster output, the tradeoff |
| plugins | build a plugin from scratch, what makes one worth installing |
| subagents | agent teams, worktree isolation, when parallel pays off |
| mcp integration | wire up MCP servers, use them inside sessions |
| hooks v2 | command vs http vs prompt hooks, the async pattern |
copy one, wire it up, done. each is a standalone bash script. full guide →

|---|---|---|
| safety-guard | PreToolUse | blocks force push, rm -rf /, DROP TABLE, curl-pipe-sh |

- CLAUDE.md templates · starter configs for TypeScript, Python, Rust, Next.js
- example agents · 4 agents, each teaching a different pattern
- example commands · 2 commands you can copy to any project
- handoff plugin · PreCompact context preservation
- broadcast plugin · async notifications on git events
this repo runs on its own patterns.
- CI workflows for validation, freshness, competitive intel, community signal, releases, AI-assisted review
- 9 standalone hooks + per-plugin hooks across cc / lore / time
- AI-powered checks use haiku so monthly CI cost stays under a couple of dollars
- automation handles the mechanical work so judgment-heavy decisions stay human
these all came out of living in claude code every day. each solves a specific problem i kept hitting.
