Navigator Features Skill

Display and toggle Navigator features with an interactive table. Helps users understand what's enabled and customize their setup.

When to Invoke

Invoke this skill when the user:

• Says "show my features", "navigator features", "what features are enabled"
• Says "enable [feature]", "disable [feature]", "turn on/off [feature]"
• Says "configure navigator", "my navigator settings"
• Asks "what can navigator do?", "what features are available?"

**DO NOT invoke** if:

• User is asking about project features (not Navigator)
• User is in middle of implementation
• Just starting session (use nav-start instead)

Execution Steps

Step 1: Read Current Configuration

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/cache/navigator-marketplace/navigator}"
[ -d "$PLUGIN_DIR" ] || PLUGIN_DIR="$HOME/.claude/plugins/marketplaces/navigator-marketplace"
python3 "$PLUGIN_DIR/skills/nav-features/functions/feature_manager.py" show

This displays the feature table (one row per configurable Navigator feature, current version's number in the header):

Step 2: Handle Toggle Request (If Applicable)

If user requested to enable/disable a feature:

PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/cache/navigator-marketplace/navigator}"
[ -d "$PLUGIN_DIR" ] || PLUGIN_DIR="$HOME/.claude/plugins/marketplaces/navigator-marketplace"
# Enable a feature
python3 "$PLUGIN_DIR/skills/nav-features/functions/feature_manager.py" enable task_mode

# Disable a feature
python3 "$PLUGIN_DIR/skills/nav-features/functions/feature_manager.py" disable loop_mode

**Supported features**:

Core (config-toggled):

• `task_mode` - Unified workflow orchestration
• `tom_features` - Theory of Mind (verification checkpoints, profile, diagnostics)
• `loop_mode` - Autonomous loop execution
• `simplification` - Code cleanup before commit
• `auto_update` - Auto-update on session start
• `knowledge_graph` - Unified project knowledge + memories (v6.0.0)
• `multi_agent` - Parallel agent orchestration via `nav-multi` (v6.0.0)

Hooks (config-toggled, edit with caution):

• `compact_hook` - Pre-compact summary injection
• `workflow_enforcer_hook` - Mandatory WORKFLOW CHECK block (disabling weakens guardrails)
• `read_guard_hook` - Anti upfront-loading guard
• `workflow_state_hook` - Tracks task/phase across the session
• `task_graph_sync_hook` - Auto-syncs tasks into knowledge graph
• `profile_sync_hook` - Auto-captures profile corrections

v7 hooks runtime (config-toggled; new blocking/injecting features ship OFF):

• `dispatcher` - Single hook dispatcher runtime (`nav_dispatch`); ON by default —

disabling turns off ALL hook ops at once

• `tier1` - Zero-token answers for whitelisted prompts (per-rule flags live under

`tier1.rules.*` in `.agent/.nav-config.json`; edit those directly)

• `stop_completion` - Completion gate on Stop via decision:block

(`stop_completion.continue_enabled` stays false; `max_continues` caps at 2)

• `jit_memory` - Just-in-time memory injection after tool use
• `subagent_context` - Project context injection into subagents

(`subagent_context.budget_chars`, default 2000)

• `failure_diagnosis` - Graph-pitfall injection on PostToolUseFailure (ships OFF)
• `config_guard` - systemMessage warning on invalid `.nav-config.json` edits

(safety surface, ON by default)

• `setup_hook` - One-line runtime status on the Setup event (safety surface,

ON by default)

Install-based:

• `mu
