README

Excerpt

Agent Common (Shared Preamble)

Memory First (CRITICAL — DO NOT SKIP)

Read memory before any work:

Bash(command="mkdir -p .cc10x")
Read(file_path=".cc10x/activeContext.md")
Read(file_path=".cc10x/patterns.md")
Read(file_path=".cc10x/progress.md")

Memory contains prior decisions, known gotchas, and current context. Without it, you work blind.

Narrower agent protocols win: if your agent doc deliberately narrows this protocol (anti-anchoring reviewers such as code-reviewer skip activeContext.md; plan-gap-reviewer reads no memory at all), follow the agent doc — the narrowing is intentional, not an omission.

This is the opening of the README. Read the full README on GitHub.
