Florian BRUNIAUX 46c5862c4e fix(docs): critical factual corrections v3.6.1

Major audit correcting misleading documentation about Claude Code behavior:

### Fixed
- `--add-dir`: permissions (not context loading)
- `excludePatterns` → `permissions.deny` (never existed)
- `.claudeignore` removed (not an official feature)
- "selective loading" myth → lazy loading reality
- Invented CLI flags (`--think`, `--headless`, `--learn`) → prompt keywords
- `@` file reference: "loads automatically" → "reads on-demand"

### Added
- Session Search Tool (`cs`) - zero-dep bash script for finding sessions
- Security section: Known limitations of permissions.deny

[3.6.1] - 2026-01-15

Fixed - Critical Factual Corrections

Major audit identifying and correcting factual errors that could mislead users about Claude Code's actual behavior.

1. `--add-dir` Flag (Wrong Description → Permissions, Not Context Loading)

Before: Documented as "loading directories into context" / "focused context" Reality: Grants tool access to directories outside CWD (permissions only, no token impact)

File	Correction
guide/ultimate-guide.md	"focused context" → "allow tool access outside CWD"
guide/cheatsheet.md	"Add directory" → "Allow access outside CWD"
machine-readable/reference.yaml	"limit loaded dirs" → "access dirs outside CWD"
quiz/questions/10-reference.yaml	Question + explanation corrected

2. `excludePatterns` → `permissions.deny` (Never Existed)

Before: Documented excludePatterns as a valid settings key Reality: Never existed - the correct syntax is permissions.deny

File	Correction
guide/ultimate-guide.md	New syntax + warning
guide/data-privacy.md	New syntax + deprecation note
examples/scripts/audit-scan.sh	Detection + message fixed
tools/audit-prompt.md	3 references corrected

3. `.claudeignore` Removed (Does Not Exist)

Before: Documented as a file exclusion mechanism like .gitignore Reality: Not an official feature - use permissions.deny instead

File	Correction
guide/ultimate-guide.md	References → `permissions.deny`
guide/data-privacy.md	Section removed
CHANGELOG.md:1244	Historical reference corrected

4. "Selective Context Loading" Myth → Lazy Loading Reality

Before: Implied Claude loads entire codebase or selectively loads directories Reality: Claude uses lazy loading - reads files on-demand via Read/Grep tools

File	Correction
guide/ultimate-guide.md	New section explaining lazy loading
guide/cheatsheet.md	"Giant context loads" → "Vague prompts"
machine-readable/reference.yaml	"load giant context" → "bloated CLAUDE.md"

5. Invented CLI Flags (SuperClaude Extension Confusion)

Before: --think, --think-hard, --ultrathink, --headless, --learn, --uc, --web documented as official CLI flags Reality: These are SuperClaude framework extensions (prompt injection), NOT official Claude Code flags

Correction Type	Details
`--headless`	Replaced with `-p` (the actual flag for non-interactive mode)
`--think` variants	Clarified as "prompt keywords", not CLI flags
SuperClaude section	Added warning: "Non-official Extension"
Cheatsheet	Think flags table reformatted as prompt keywords
Decision tree	"Use --think" → "Use extended thinking prompts"

6. `@` File Reference Behavior

Before: "Claude loads file content automatically" After: "Signals Claude to read files on-demand via tools"

Added - Session Search Tool (`cs`)

Problem solved: After weeks of Claude Code usage, finding past conversations becomes painful:

claude --resume is interactive (no search)
Sessions accumulate in ~/.claude/projects/
No quick way to search "that session where I talked about auth"

Solution: cs — Zero-dependency bash script for searching and resuming sessions.

cs                    # List 10 recent sessions (15ms)
cs "authentication"   # Full-text search (400ms)
cs -n 20              # More results

# Output:
# 2026-01-15 08:32 │ my-project │ Implement OAuth flow for...
#   claude --resume 84287c0d-8778-4a8d-abf1-eb2807e327a8

Performance comparison:

Tool	List	Search	Deps	Resume cmd
`cs` (this script)	15ms	400ms	None	✅ Shown
claude-conversation-extractor	230ms	1.7s	Python	❌
`claude --resume` native	500ms+	❌	None	Interactive

Files created/modified:

File	Description
`examples/scripts/session-search.sh`	Script in repo (source)
`examples/README.md`	Entry in Scripts table
`guide/observability.md`	Section "Session Search & Resume"
`guide/ultimate-guide.md:505-524`	Examples in "Finding session IDs"
`README.md:398-403`	Section "Utility Scripts"
`machine-readable/reference.yaml`	`deep_dive.session_search` entry

Installation (local):

# Copy script
cp examples/scripts/session-search.sh ~/.claude/scripts/cs
chmod +x ~/.claude/scripts/cs

# Add alias to shell
echo 'alias cs="~/.claude/scripts/cs"' >> ~/.zshrc
source ~/.zshrc

Added - Security Documentation

Root Cause Analysis

The factual errors originated from:

SuperClaude framework confusion: User had ~/.claude/FLAGS.md with custom flags that were documented as if official
Assumption propagation: "selective loading" concept was assumed from other AI tools
Outdated syntax: excludePatterns may have been planned but never implemented

[2.9.0] - 2026-01-12

Fixed

MCP detection bug in audit-scan.sh (~60 lines modified)
- Root cause: Script searched for ~/.claude/mcp.json which doesn't exist
- Actual location: Claude Code stores MCP config in ~/.claude.json under projects.<path>.mcpServers
- Solution: Multi-source detection with priority:
  1. ~/.claude.json → projects.<cwd>.mcpServers (most common)
  2. ./.claude/mcp.json (project-level)
  3. ~/.claude/mcp.json (legacy global)
- JSON output now includes detailed mcp section (configured, count, servers, source)
- Human output shows server count and source location
Bug 0\n0 in claude_md_refs (~8 lines)
- Root cause: grep -c ... || echo "0" could produce double output
- Solution: Rewritten count_pattern() function to properly capture and return count

Changed

audit-scan.sh enhanced (~50 lines)
- Added MCP_SOURCE variable to track where MCP config was found
- Added MCP_COUNT variable for server count
