Second installment of Oleg Efimov's Claude Code series. ## Author's thesis (Adler Q1+Q2) **What is the article about?** What the smallest correctly-scoped Claude Code configuration should contain, and where personal versus shared project settings belong. **What is being argued?** A small, correctly scoped configuration outperforms a large one: commit shared project instructions, keep personal overrides local, and treat CLAUDE.md as operational guidance rather than a security control — real access boundaries need OS-level or sandbox enforcement, not prose deny rules. ## Key arguments (≤3) 1. **Understand the settings hierarchy before adding automation** — most setup mistakes come from skipping the fundamentals of how personal, project, and local settings merge or override. 2. **Deny rules are a workflow guardrail, not a security boundary** — settings.json deny rules can be worked around; they reduce accidental mistakes, they don't stop a determined bypass. 3. **CLAUDE.md is for operations, not enforcement** — the file should describe how the project works, not attempt to be the mechanism that prevents bad actions. ## Claim atoms ### Understand the settings hierarchy before adding plugins or automation > [!quote] ID:rw_01kz7sswrag24xqdb0n62r147r > most people skip the fundamentals Where/why: opens the article's setup-order argument. ### Deny rules are a guardrail, not a security boundary > [!quote] ID:rw_01kz7ssz0j23s9z8m27nhqtw7c > deny rules in settings.json are not a reliable security boundary Where/why: the article's central security-scoping claim. ### CLAUDE.md is for operational guidance, not enforcement > [!quote] ID:rw_01kz7sszny7w8badnr49jjp1qr > CLAUDE.md is for operations Where/why: closes the loop on what CLAUDE.md should and shouldn't be asked to do. ## Permanent candidates - **Prose configuration cannot substitute for a real access boundary** — the article's deny-rules claim is a distinct, genuine claim worth its own Permanent note (not the same as the series' generic enforceable-layer boilerplate candidate, which duplicates an existing note — see the Full Workflow Literature Note). ## Processing checklist - [x] Checked for an existing Permanent note on the generic series candidate — exists, linked rather than duplicated - [x] Created a new Permanent note for this article's distinct deny-rules claim - [x] Connect into the relevant MOC — [[3.
