Navigator

Finish What You Start

Sessions that last. AI that learns. Features that ship.

What is Navigator?

Navigator is a Claude Code plugin that implements context engineering for AI-assisted development.

Instead of loading all your documentation upfront (and crashing at exchange 7), Navigator loads what you need, when you need it—keeping 94% of your context window available for actual work.

For developers using Claude Code who want sessions that finish features instead of crash mid-way.

The Loop You're Stuck In

You know the pattern:

Exchange 5:  Claude forgets your recent changes
Exchange 7:  Hallucinations start ("that function doesn't exist")
Exchange 8:  "Context limit reached"

Restart. Reload. Re-explain everything. Repeat.

You loaded 150k tokens of documentation "just in case."

You used 8k.

The rest? Noise drowning out signal.

Break The Loop

Navigator implements context engineering—load what you need, when you need it.

Metric	Without Navigator	With Navigator
Tokens loaded	150,000	12,000
Session length	5-7 exchanges	20+ exchanges
Context at end	95% (crashed)	35% (comfortable)
Token savings	—	92%

Result: Sessions that actually finish what they start.

And Your AI Gets Smarter

Navigator v5.0 adds Theory of Mind—Claude learns you.

nav-profile: Remembers your preferences across sessions

"Remember I prefer concise explanations"
→ Applied in future sessions
→ Auto-learns from corrections

nav-diagnose: Catches collaboration drift

Same correction twice → Quality check triggered
"You're not getting this" → Re-anchoring prompt

Loop Mode (v5.1): Run until done

"Run until done: add user authentication"
→ Structured completion with progress tracking
→ Dual-condition exit (heuristics + explicit signal)
→ Stagnation detection prevents infinite loops

Knowledge Graph (v6.0): Project memory that persists

"What do we know about auth?"
→ Unified search across tasks, SOPs, system docs
→ Experiential memory: patterns, pitfalls, decisions
→ Auto-surfaces relevant context on session start

Reply modes (v7.9): the reply shaped for you, switched by a sentence

"adhd mode on"
→ One next action first, bullets over prose, lists capped at five
→ Follows you across repos; "adhd mode off" ends it
→ STE mode (one idea per sentence, active voice) ships in v8.3.0

See Where You Are

Since v8 the workflow is enforced by a runtime that runs inside Claude Code, not by prose in a config file. It gates task-shaped prompts, guards fan-out reads, records what each turn finished, and writes one line to a reject log every time it says no. It also draws.

Type /nav and a pane opens beside your session:

Card	What it tells you
context	Fill percentage, trend, and whether this is a good moment to compact
session	Today's cost, tokens, cache hit rate, tokens/min
reads	Fan-out verdict and today's reject count
judge	What the typed judge decided about your last prompt, and what Navigator did
next	The current leg of the active task as a button that submits it, with an ETA
memories	Knowledge-graph memories for the open task; pin one into your next prompt

A one-line status band above the prompt shows the phase, context fill and next action without opening the pane. Requires Claude Code 2.1.287 or newer; older versions run the same behaviors through the Python fallback, without the pane.

Quick Start

Install

# Claude Code plugin marketplace
/plugin marketplace add qf-studio/navigator
/plugin install navigator

# Restart Claude Code (2.1.287+ for the in-process runtime and the /nav pane)

Code intelligence (optional). Install a language-server plugin for your stack (/plugin install pyright-lsp@claude-plugins-official, typescript-lsp, gopls-lsp, …; the server binary must be on your PATH) and the research agent answers symbol questions with go-to-definition, references and outlines instead of text search. Without one it uses Grep exactly as before. Measured on this repo: a who-calls question went from 9 requests and 284k context tokens to 5 requests and 142k, with the complete call-site list.

Initialize

"Initialize Navigator in this project"

Start Every Session

"Start my Navigator session"

That's it. Navigator handles the rest.

Optional: Typed Prompt Judge

Navigator's loop-trigger, complexity and ambiguity detectors are keyword matchers. With a TypeSafe key they get a typed judge behind them (v7.7.0): one request per prompt, decisive answers override, everything else falls back to the keywords. Measured on 60 labeled prompts, tier accuracy went from 38 to 53. Off by default because the prompt text is sent to the API.

export TYPESAFE_API_KEY=...      # or: write it to ~/.config/typesafe/api_key (chmod 600)

Then say enable judge and verify with python3 hooks/nav_hook_lib/judge.py --check from the plugin root. Setup and tuning: .agent/sops/integrations/typesafe-judge-setup.md.

What You Get

Skills that auto-invoke on natural language:

"Start my Navigator session"              → Session with 92% savings
"Create a React component for profile"    → Component + tests + styles
"Add an API endpoint for posts"           → Endpoint + validation + tests
"Create context marker: checkpoint"       → 97% context compression
"Run until done: add dark mode"           → Loop mode completion
"Deep research on WebGPU browser support"  → Cited report + graph memories
"Enable judge"                             → Typed Jev judgments behind the prompt gates
"adhd mode on"                             → Replies shaped for you, across repos
/nav                                       → Live pane: context, cost, rejects, next leg

No commands to memorize. Skills detect intent and execute.

Stop Restarting. Start Shipping.

Your sessions crash because context management is broken by default.

Navigator fixes this with context engineering—the same principles Anthropic recommends.

92% token savings. 20+ exchange sessions. Verified metrics.

/plugin marketplace add qf-studio/navigator
/plugin install navigator

Finish what you start.

---

Troubleshooting

Skill loads but prints docs instead of executing, or /nav is missing

claude plugin update navigator@navigator-marketplace

Then restart Claude Code. Outdated plugin version, or the pane needs 2.1.287+.
