+## Safety & Change Management
+
+Grokkit is designed to work seamlessly with Git. Rather than creating redundant `.bak` files, we lean on Git's powerful version control to manage changes and rollbacks.
+
+### The Safety Workflow
+
+1.  **Preview**: Every command that modifies files (like `edit`, `lint`, `docs`) shows a diff-style preview first.
+2.  **Confirm**: You must explicitly confirm (`y/N`) before any changes are written to disk.
+3.  **Git Integration**: Use Git to manage the "pre-staged," "staged," and "committed" degrees of change.
+
+### Managing Undesired Changes
+
+If you've applied a change that you don't like, Git makes it easy to roll back:
+
+- **Unstaged changes**: If you haven't `git add`-ed the changes yet:
+  ```bash
+  git restore <file>
+  ```
+- **Staged changes**: If you've already staged the changes:
+  ```bash
+  git restore --staged <file>
+  git restore <file>
+  ```
+- **Committed changes**: If you've already committed the changes:
+  ```bash
+  git revert HEAD
+  # or to reset to a previous state:
+  git reset --hard HEAD~1
+  ```
+
+By using Git, you have a complete audit trail and multiple levels of undo, ensuring your codebase remains stable even when experimenting with AI-driven refactors.

+- NO monkey-patching: never assign to runtime.GOOS, exec.Command, os.Stdout, os.Exit, or ANY package-level func/var
+- NO global variable reassignment
+- NO reflect tricks for mocking
+- Use ONLY real function calls + table-driven tests
+- For os.Exit or stdout testing, use simple smoke tests or pipes (no reassignment)
+- Prefer simple happy-path + error-path tests

+
+Exact rules:
+- Derive test names from functions (e.g. isInstalled → TestIsInstalled_Unit)
+- The XXX in t.Skip MUST exactly match the live function name
+- t.Parallel() on unit tests only

+# `grokkit query` Simple Query Tool
+## Priority: x of 13
+
+**Description**: A "one shot" prompt/answer query tool. Use it to ask StackOverflow style questions, like "how do I do x? Or What library do I use for y?". The sweet spot is concise, actionable answers with just enough context, a code snippet if relevant, and no unnecessary fluff. Think: problem solved in 100-300 words, tops. However, a "wordy" flag will be included to allow for full "textbook" style answers, as well.
+
+## Problem It Solves
+
+Reduces the amount of context switching needed to answer basic programming questions.
+
+### Example Short Query 1: 
+
+```
+grokkit query "What is the difference between a slice and a map in Go?"
+
+Slices are dynamic arrays for ordered sequences of elements (e.g., `[]int`), with length/capacity and fast index access. Use for lists or queues; append with `append(s, val)`.
+
+Maps are unordered key-value stores (e.g., `map[string]int`), for fast lookups/deletes via hashing. Use for dictionaries or caches; access with `m[key]`.
+
+Key diffs: Slices are indexed by integers and ordered; maps use arbitrary keys and are unordered. Both are reference types, initialized with `make`.
+
+Example:
+    ```go
+    s := []int{1, 2, 3} // Slice
+    m := map[string]int{"a": 1} // Map
+    ```
+```
+### Example Short Query 2: 
+```
+"$ grokkit query "Are there any other languages with a concept like Python list comprehensions?"
+
+Yes, several languages have similar concise syntax for creating collections via expressions:
+
+- **Haskell**: List comprehensions, e.g., `[x*2 | x <- [1..5]]` (outputs `[2,4,6,8,10]`).
+- **Scala**: For-comprehensions, e.g., `for (x <- 1 to 5) yield x*2`.
+- **JavaScript (ES6+)**: Array methods like `map`/`filter`, e.g., `[1,2,3,4,5].map(x => x*2)`. Not identical, but functional equivalent.
+- **C#**: LINQ queries, e.g., `from x in Enumerable.Range(1,5) select x*2`.
+- **Rust**: Iterators with `map`/`collect`, e.g., `(1..=5).map(|x| x*2).collect::<Vec<i32>>()`.
+
+Python's are inspired by Haskell. For exact matches, Haskell is closest.
+```
+
+### Example Long Query: 
+```
+$ grokkit query "What is the difference between a slice and a map in Go?" --wordy
+
+Ah, slices and maps in Go—two of the language's built-in data structures that make life easier (or at least less array-tastic) for developers. They're both reference types, meaning they're lightweight and point to underlying data, but they serve very different purposes. I'll break it down step by step, with some examples, and keep it straightforward. If Go had a sense of humor, it'd say slices are for cutting things up neatly, while maps are for when you lose your keys... again.
+
+### What is a Slice?
+A slice is essentially a dynamic, resizable view of an array. Think of it as a flexible array that can grow or shrink without you having to manage the underlying memory manually. Slices are backed by an array under the hood, but they're more convenient because:
+- They have a length (how many elements are currently in it) and a capacity (how much room is allocated before it needs to resize).
+- You can append to them, slice them further (hence the name), and they're zero-initialized by default.
+- They're ordered: Elements are accessed by integer indices, starting from 0.
+
+**Key traits:**
+- Type: `[]T` (e.g., `[]int` for a slice of integers).
+- Ordered? Yes.
+- Use case: Lists, stacks, queues, or any sequence of items where order matters and you need fast random access.
+
+**Example:**
+
+    ```go
+    package main
+    
+    import "fmt"
+    
+    func main() {
+        // Create a slice with make (initial length 3, capacity 5)
+        s := make([]string, 3, 5)
+        s[0] = "apple"
+        s[1] = "banana"
+        s[2] = "cherry"
+    
+        // Append to it (grows if needed)
+        s = append(s, "date")
+    
+        fmt.Println(s)       // Output: [apple banana cherry date]
+        fmt.Println(s[1:3])  // Slicing: [banana cherry]
+    }
+    ```
+
+Slices are great for when you want array-like behavior without the fixed-size hassle of actual arrays in Go.
+
+### What is a Map?
+A map is Go's version of a hash table or dictionary: an unordered collection of key-value pairs. You use it to associate unique keys with values, and it's super efficient for lookups, inserts, and deletes (average O(1) time complexity, thanks to hashing).
+- Keys must be comparable (e.g., strings, ints, structs without pointers), but values can be anything.
+- Maps are unordered, so don't rely on iteration order—it's not guaranteed (though as of Go 1.12, it's pseudo-random but consistent per run for debugging).
+- They're also nil-safe: An uninitialized map is nil, and you can't add to it until you `make` it.
+
+**Key traits:**
+- Type: `map[K]V` (e.g., `map[string]int` for string keys and int values).
+- Ordered? No (unordered by design).
+- Use case: Lookup tables, caches, configurations, or anywhere you need fast key-based access without caring about order.
+
+**Example:**
+
+    ```go
+    package main
+    
+    import "fmt"
+    
+    func main() {
+        // Create a map with make
+        m := make(map[string]int)
+        m["apple"] = 1
+        m["banana"] = 2
+        m["cherry"] = 3
+    
+        // Access by key
+        fmt.Println(m["banana"])  // Output: 2
+    
+        // Check if a key exists
+        value, exists := m["date"]
+        if !exists {
+            fmt.Println("Date not found!")  // This will print
+        }
+    
+        // Delete a key
+        delete(m, "cherry")
+    }
+    ```
+Maps are your go-to when you need to map one thing to another without the linear search nonsense.
+
+### Key Differences
+- **Structure and Purpose**: Slices are sequences of elements (like a list or array), ideal for ordered collections. Maps are associative arrays for key-value storage, perfect for quick lookups by key.
+- **Access Method**: Slices use integer indices (e.g., `s[42]`). Maps use keys of any hashable type (e.g., `m["foo"]`).
+- **Ordering**: Slices preserve insertion order and allow indexing. Maps are unordered—iteration might give you keys in a seemingly random order.
+- **Resizing and Capacity**: Slices have explicit length and capacity; they can grow via `append`. Maps grow automatically as you add elements, but you don't control capacity directly.
+- **Initialization**: Both often use `make` for creation, but slices can be literals like `[]int{1, 2, 3}`, while maps use `map[string]int{"a": 1}`.
+- **Performance**: Slices are contiguous in memory (fast iteration and access), maps use hashing (fast lookups but more overhead for small sizes).
+- **Nil Behavior**: A nil slice can still be appended to (it acts like an empty slice). A nil map will panic if you try to read/write to it.
+- **When to Use Which**: Use a slice if you need a list (e.g., processing a queue of tasks). Use a map if you need to associate data (e.g., user IDs to profiles).
+
+In short, if slices are like a neatly organized toolbox drawer, maps are like a junk drawer where you can find stuff quickly by yelling its name—but don't expect it to be in any particular spot.

+# `grokkit scaffold`
+## Priority: 1 of 12
+
+**Description**: AI-powered code generation that creates new files from natural language descriptions, learning from your existing codebase patterns to produce idiomatic, ready-to-compile output.
+
+## Problem It Solves
+
+Every existing grokkit command operates on *existing* files (`edit`, `agent`, `lint`, `docs`, `testgen`). There is no command to *create* a new file from scratch. Developers spend significant time writing boilerplate for new handlers, services, models, CLI commands, middleware, etc. `scaffold` fills this gap.
+
+## Benefits
+
+- **Pattern-aware**: Reads similar existing files for package names, import styles, error handling conventions, struct naming, and logger usage before generating.
+- **Idiomatic output**: Produces code that looks like it was written by the same developer — same patterns as the rest of the codebase, not generic AI output.
+- **Multi-language**: Works for any language the project already supports (Go, Python, JS/TS, etc.), with lang detected from the output path or `--lang` flag.
+- **Optional test companion**: With `--with-tests`, also generates a corresponding test file using the same testgen prompt logic.
+- **Safe preview**: Shows a diff/preview before writing, requires confirmation (or `--yes` to skip).
+- **No overwrites**: Refuses to overwrite an existing file unless `--force` is passed.
+
+## CLI Examples
+
+```bash
+# Generate a new Cobra CLI command file
+grokkit scaffold cmd/export.go "export command that writes chat history to JSON or CSV"
+
+# New internal package
+grokkit scaffold internal/cache/cache.go "simple in-memory LRU cache with TTL support"
+
+# Generate with a companion test file
+grokkit scaffold internal/git/tag.go "functions to list and create git tags" --with-tests
+
+# Python module
+grokkit scaffold src/auth/jwt.py "JWT encode/decode utilities using PyJWT"
+
+# Skip confirmation
+grokkit scaffold cmd/webhook.go "webhook command that posts PR descriptions to Slack" --yes
+
+# Preview only (no write)
+grokkit scaffold cmd/watch.go "file watcher that reruns lint on save" --dry-run
+```
+
+## High-Level Implementation
+
+1. **Input validation**: Check target path doesn't already exist (error unless `--force`). Detect language from file extension.
+2. **Context harvesting**: Walk sibling files in the same directory and the most structurally similar files in the project (e.g., other `cmd/*.go` if generating a command). Read them for patterns.
+3. **Prompt construction**:
+   - System: "You are an expert Go/Python/etc. engineer. Given existing code samples, generate a new file that matches the codebase's conventions exactly. Return only the file content — no explanations, no markdown."
+   - User: paste harvested sibling files as context + target path + description.
+4. **Streaming response**: Use `client.StreamSilent` (same as `edit`/`testgen`).
+5. **Clean output**: Run through `grok.CleanCodeResponse` to strip any markdown fences.
+6. **Preview**: Print file content with a header showing the target path. Prompt `(y/n)`.
+7. **Write**: Create parent directories if needed (`os.MkdirAll`), write file.
+8. **Optional test generation**: If `--with-tests`, reuse testgen logic to generate companion test file with the same preview/confirm flow.
+
+## Flags
+
+| Flag | Description |
+|---|---|
+| `--with-tests` | Also generate companion test file |
+| `--yes` / `-y` | Skip confirmation prompt |
+| `--dry-run` | Preview only, do not write |
+| `--force` | Overwrite if target file already exists |
+| `--lang` | Override language detection (go, python, js, ts, rust, ruby) |
+| `--model` / `-m` | Override model |
+| `--context-files` | Comma-separated paths to use as context (overrides auto-detection) |
+
+## Implementation Notes
+
+- **Context size**: Cap harvested context at ~4000 tokens to avoid prompt bloat. Prefer the most relevant files (same directory, same `package` name for Go).
+- **Go specifics**: Extract `package` name from sibling files and inject it at the top of the prompt so the AI uses the correct package declaration.
+- **Reuse existing patterns**: Share `internal/linter.DetectLanguage`, `grok.CleanCodeResponse`, and the standard preview/confirm UX from `edit.go`.
+- **Effort**: Medium (~250–350 LOC). Most complexity is in the context-harvesting logic.
+
+## ROI
+
+**High**. This closes the only remaining gap in grokkit's file lifecycle coverage:
+
+| Lifecycle stage | Command |
+|---|---|
+| Create new file | **scaffold** ← missing |
+| Edit existing file | `edit` |
+| Multi-file changes | `agent` |
+| Review changes | `review` |
+| Document code | `docs` |
+| Generate tests | `testgen` |
+| Commit | `commit` |
+
+Developers scaffold new files multiple times per day. Making that AI-assisted and pattern-aware is a force multiplier for the entire tool.

+# `grokkit admin` administration tools
+
+### Category: Nice to Have
+
+Add an `admin` command that, if an `XAI_MGMT_KEY` is set in the environment, displays up-to-date token usage on the api account/team.
+
+### Details
+- **Command**: `grokkit admin`
+- **Subcommands**:
+    - `grokkit admin token-usage`    <-- default (shows token usage for current team)
+    - `grokkit admin credit-balance` <-- shows credit balance for current team
+    - `grokkit admin models`         <-- shows available models
+    - `grokkit admin api-keys`       <-- shows available API keys
+
+- **Condition**: Must check for `XAI_MGMT_KEY` env var.
+- **Functionality**: Fetch and display token usage stats from the [XAI MANAGEMENT API](https://docs.x.ai/developers/rest-api-reference/management.
+- **Goal**: Help me monitor my API costs and limits directly from the CLI.
+
+NOTE: If possible, it would be cool if this command was "hidden" if the XAI_MGMT_KEY is not set.

+# `grokkit audit`
+**Description**: Comprehensive AI-powered code audit for security, performance, best practices, and potential bugs across single files or entire projects.
+
+**Benefits**:
+- Deep analysis beyond static linters: vulns (e.g., SQLi, race cond), perf hotspots, Go idioms violations.
+- Generates actionable report + diff previews for fixes.
+- Multi-language support (reuse testgen/lint patterns).
+- Boosts code quality/PR readiness.
+
+**High-level implementation**:
+- Detect lang/files (internal/linter), collect code snippets/context.
+- Prompt Grok: "Audit for security, perf, best practices, bugs. List issues prioritized + suggested code fixes."
+- Output: Markdown report (sections: Critical/High/Med/Low), optional `--fix` generates edit previews.
+- Reuse `edit` preview/apply workflow; add `--apply` flag.
+
+**CLI example**:
+```
+grokkit audit main.go                    # Single file report
+grokkit audit ./cmd --lang=go             # Dir, lang filter
+grokkit audit . --fix                     # Report + fix previews
+grokkit audit . --fix --yes               # Auto-apply fixes (dangerous, preview first)
+```

+# `grokkit agent` cnotes integration
+
+**Description**: Wrappers for your `cnotes` CLI logging suite. Allows Grok to automatically log coding sessions, notes, progress during agent workflows (e.g., "start work on feature", "log bug found").
+
+## Problem It Solves
+
+Developers track time/effort manually. Integrate `cnotes` (cnadd/cndump/etc.) for AI-assisted logging: timestamps, descriptions, stats—seamless with code edits.
+
+## Benefits
+
+- **Automated logging**: Grok logs at key points (start/edit/commit).
+- **Queryable**: Search/dump stats via AI ("Show time on agent tasks today").
+- **Safe**: Append-only (`cnadd`), read-only queries (`cnfind`/`cncount`); no deletes.
+- **Terminal-native**: Fast C impl, no deps.
+- **Workflow boost**: "Refactor → log changes → stats".
+
+## Agent Tool Examples
+
+```
+grokkit agent "Start logging session, fix main.go, log completion"
+# Grok: cnadd "start: agent refactor main.go" → edits → cnadd "done: fixed errors"
+```
+
+```
+grokkit agent "Log today's coding stats before planning"
+# Grok: cncount → cnfind "today" → "2h on edits, 3 sessions"
+```
+
+## High-Level Implementation
+
+1. **Detect cnotes**: Run `cnhelp` or `which cnotes`.
+2. **Tool schemas**:
+   - `log_note(message: string) → ok`
+   - `list_notes(filter?: string) → string`
+   - `session_stats() → string`
+3. **Wrappers** in `internal/tools/cnotes.go`:
+   ```go
+   func LogNote(ctx context.Context, args map[string]any) (string, error)
+   ```
+4. **Agent integration**: Auto-log on milestones; user-prompted.
+5. **Safety**:
+   - Only `cnadd`/`cndump`/`cnfind`/`cncount`.
+   - Preview log message.
+   - Config: `[tools.cnotes.enabled]`.
+6. **Parsing**: Stdout JSON? Or simple text.
+
+## Flags / Config

+- **Commands**: cnadd (log), cndump (all), cnfind (search), cncount (stats), cndel (archive—whitelist carefully).
+- **Extend agent**: Tool calls in loop.
+- **Errors**: Custom CnotesError.
+- **Tests**: Mock `exec.Command`, table-driven.

+# Grokkit Interactive Agent
+
+
+## Goal
+
+Add a persistent, conversational **agent mode** to Grokkit so I can chat interactively in the terminal and have Grok directly edit code, run tests, commit, etc., without any copy-paste friction.
+
+This is the natural evolution of the current `chat` and `agent` commands — turning the terminal into a true agentic partner instead of a one-shot prompt tool.
+
+## Command
+
+```bash
+grokkit chat --agent # or new subcommand: grokkit agent-chat
+```
+
+(Keep the existing simple `chat` mode untouched; add an `--agent` flag or a dedicated `agent-chat` command.)
+
+## Core Features
+
+- Persistent session using the existing `chat_history.json` (with optional `--new-session` flag)
+- Full tool-calling loop: I (Grok) can invoke any existing Grokkit primitive:
+  - `edit`
+  - `scaffold`
+  - `testgen`
+  - `lint`
+  - `review`
+  - `commit` / `commit-msg`
+  - `docs`
+  - etc.
+- Safe-by-default workflow:
+  - Always preview changes (diff style, same as current `edit`/`scaffold`)
+  - Require explicit confirmation (`y/n` or `--yes`)
+  - Preview and confirm all changes before application
+- Ability to chain actions naturally in conversation:
+  - “The scaffold tests are flaky on Windows paths — fix it and add a test case.”
+  - “Refactor the context harvester to use rg, then run make test.”
+  - “Write a new command for todo prioritization and commit it.”
+- Optional `--dry-run` and `--model` flags (inherited from root)
+
+## Acceptance Criteria
+
+- `make test` remains fast (no new API cost in normal tests)
+- Live agent mode respects the same `-short` gating pattern we just built for scaffold
+- Session survives across multiple `grokkit` invocations (or can be started fresh)
+- All edits go through the existing safe preview/confirm flow — no silent changes
+- Works with the full Grok context window (no early compaction)
+- Can be extended later with vector memory or external tool plugins
+
+## Why This Matters
+
+This removes the last remaining copy-paste friction between me and the codebase. The 45-minute scaffold test iteration we just did showed the productivity gain; this turns that gain into a permanent workflow. Closes the “agentic chat” vision we discussed.

+**Description**: Wrappers for Makefile targets (test/lint/build/cover). Enables Grok to run/verify builds mid-agent workflow (e.g., "edit, test, fix loops").
+
+## Problem It Solves
+
+Agent edits code but can't auto-verify compilation/tests—manual `make test` context-switch.
+
+## Benefits
+
+- **Automated verification**: Post-edit `make test` + analyze failures.

+**Description**: Safe, AI-orchestrated wrappers for Gitea `tea` CLI commands. Enables Grok to manage repos (list/create PRs/issues, comments) as part of agent workflows, with previews and confirmations.
+
+## Problem It Solves
+
+Grokkit's `agent` excels at code edits but lacks repo mgmt. Developers context-switch to browser/CLI for Gitea actions. Integrate `tea` for seamless: "Review PRs, create issue for bugs, log progress".
+
+## Benefits
+
+- **Safe execution**: Whitelisted commands/args, dry-run previews, confirm destructive ops (merge/push).
+- **AI reasoning**: Grok decides *when* to call `tea` (e.g., "After edits, create PR").
+- **Logging**: All calls logged to `~/.config/grokkit/tools.log`.
+- **Repo-aware**: Combines with git (`internal/git`), code edits.
+- **No new deps**: Uses `os/exec` for `tea` (assume installed).
+
+## Agent Tool Examples
+
+```

+# Grok: Runs lint → tea issue create "High-risk refactor"
+```
+
+## High-Level Implementation
+
+1. **Detect tea**: Check `exec.Command("tea", "version")`.
+2. **Tool schemas** (Grok tool-calling JSON):
+   - `list_prs(state: "open") → string`
+   - `create_pr(title, body, base) → pr_url`
+   - `comment_pr(pr_id, body)`
+   - `merge_pr(pr_id)`
+3. **Wrapper funcs** in `internal/tools/tea.go`:
+   ```go
+   func ListPRs(ctx context.Context, args map[string]any) (string, error)
+   ```
+4. **Agent loop** (`cmd/agent.go`): Parse tool calls → Execute → Feed output back.
+5. **Safety**:
+   - Whitelist: pr ls/create/comment/merge, issue create/comment.
+   - Preview: Print `tea ...` + expected output.
+   - Confirm: User y/n for each.
+6. **Config**: `[tools.tea.enabled]`, `[tools.tea.gitea_url]`.
+
+## Flags / Config

+| Key | Description |
+|-----|-------------|
+| `tools.tea.enabled` | Enable tea tools |
+| `tools.tea.gitea_url` | Override repo URL |
+| `--dry-run` | Simulate tool calls |
+
+## Implementation Notes
+
+- **Extend agent**: Modify plan phase to include tool suggestions.
+- **Error handling**: `internal/errors` + GitError-like TeaError.
+- **Tests**: Table-driven `TestTeaTools` with mocks (`exec.Command` patching).
