Configure Claude Code for the full 1M-token context window and optimal operation in the Heady ecosystem: - autoCompactWindow=1000000 + ANTHROPIC_BETAS=context-1m-2025-08-07 so the whole context window is used before summarization - raised output/thinking/MCP token budgets (env) - effortLevel=xhigh, always-thinking, file checkpointing, 90d retention - enableAllProjectMcpServers for the Heady MCP toolchain - permissions: allow Heady dev toolchain; deny-read secrets (.env/.heady/keys); block/gate destructive commands - SessionStart hook injects live repo context each session - PreToolUse(Bash) hook denies catastrophic commands, asks before destructive ones (DROP TABLE, gcloud delete, wrangler delete) - README documenting every knob

Summary
Adds a Claude Code configuration (
.claude/) tuned for the full 1M-token context window and Heady-optimal operation. This repo previously had no.claude/config at all.Maximum context
autoCompactWindow: 1000000+env.ANTHROPIC_BETAS=context-1m-2025-08-07— the whole 1M window is used before any summarization (pair with a 1M-capable model, e.g.claude-opus-4-8[1m]).autoCompactEnabled: true— long sessions summarize at the boundary instead of hard-failing.env:CLAUDE_CODE_MAX_OUTPUT_TOKENS=64000,MAX_THINKING_TOKENS=32000,MAX_MCP_OUTPUT_TOKENS=50000.effortLevel=xhigh, always-thinking + thinking summaries, file checkpointing, 90-day transcript retention.Heady-optimal operation
enableAllProjectMcpServers: true— auto-approves the Heady MCP toolchain..env,.heady/**, keys,*.pem); block/gate destructive commands.SessionStarthook (hooks/session-context.sh) — injects live repo context (branch, HEAD, present canonical configs, Stop Rule) at session start.PreToolUse(Bash)hook (hooks/guard-bash.sh) — hard-denies catastrophic commands (rm -rf /, force-push,mkfs, fork-bombs); asks before destructive-but-legitimate ones (DROP TABLE,gcloud … delete,wrangler … delete). Enforces the governance rule that irreversible actions need human confirmation.Verification
Both hooks were pipe-tested with realistic stdin payloads:
SessionStartadditionalContextJSON.rm -rf /and force-push, and asks onDROP TABLE.settings.jsonvalidated withjq..claude/README.mddocuments every knob.Notes
The 1M window requires a 1M-capable model; it is intentionally not pinned in committed settings so the team isn't forced onto one model/tier — select per session or in personal
