Move GPT off Cursor before November 12
Codex vs Cursor after OpenAI dated the Cursor GPT pipe. Install Codex CLI, pin gpt-5.6-sol or Terra, then prove a real coding turn before November 12.
Claude Code cache TTL is now a frontmatter field
Claude Code cache TTL is a per-agent frontmatter field. Pin 1h on the idle reviewer, 5m on the chatty explorer, then prove the split with /cost today.
A PreModelSwitch hook that blocks a cache-killing model swap
A PreModelSwitch hook that denies a warm /model swap so the cache stays. Prove it with /cost still saying warm, then watch auto fallback walk around it.
Claude channels from Telegram without granting root
Claude Code channels let Telegram hit a live local session. Launch it in Manual mode, skip-permissions stays off, and deny the git push on the laptop.
A Claude Code dev container is the sandbox you skipped
A claude code dev container puts the CLI in Docker so bash cannot see the host home. Persist login with CLAUDE_CONFIG_DIR, then rebuild and prove isolation.
A Claude Code status line that shows weekly remaining
A Claude Code status line that prints 5-hour and weekly remaining from stdin JSON. Paste one jq command, mock-test the invert, and stop guessing the week.
CLAUDE.md vs AGENTS.md in the same repo
Split CLAUDE.md AGENTS.md in the same repo. Keep project law in CLAUDE.md, put the agent roster in AGENTS.md, and then prove the split with two hashes.
Install claude-mem so the next session remembers
Install claude-mem with npx, not a global npm package. Curl the per-user worker port, then start a new session that prints observation IDs without a paste.

JetBrains Context indexes the repo so VS Code agents search by meaning. Install jbcontext, wire setup-agent, and prove a file-line hit without a grep crawl.
