tinillm 2.6.0

Hardware LLM capability scanner — know what runs on your machine

tinillm

A local-first LLM agent and hardware scanner — chat with your hardware, let it write code.

pipx install tinillm
tinillm

What it does

tinillm is an interactive agent that runs on your local Ollama models. Type anything at the prompt and it talks to the agent. Type /cmd and it runs a command.

• Chat with tools. The agent can read files, edit code, run bash, and search the web — all gated by a three-tier permission model (read-only / workspace-write / danger-full-access).
• Plan mode. /plan puts the model in a read-only planning pass. Approve the plan and it executes autonomously — no per-command confirmations.
• Hardware-aware. /scan tells you which LLMs fit your machine before you download 30 GB of weights. /models browses real Ollama models with fit analysis.
• Linux sandbox. When bubblewrap is installed, bash calls run in a namespace jail rooted at your workspace.
• Session persistence. Every conversation is written to a JSONL log you can /chat --resume.

Install

pipx install tinillm     # recommended: isolated per-tool environment
# or
pip install tinillm

Requires Python 3.11+ and a running Ollama server for the agent. Hardware scanning works without Ollama.

Optional on Linux:

apt install bubblewrap   # enables workspace-rooted bash sandbox

The unified prompt

Everything happens at one prompt. There's no separate "chat mode."

│ refactor agent_chat.py to extract a ChatSession dataclass
⚙  read_file(path='tinillm/run/agent_chat.py')
⚙  write_file(path='tinillm/run/chat_session.py', …)
⚙  edit_file(path='tinillm/run/agent_chat.py', …)
done — extracted ChatSession with create/handle_user_turn/handle_slash.

│ /scan
  LLM Capability Matrix
  ~1B    Perfect   Q8_0     1.9 GB   580 t/s
  ~7B    Perfect   Q6_K     6.2 GB    88 t/s
  ~13B   Perfect   Q5_K_M  10.1 GB    47 t/s

Free text → the agent. /scan, /models, /doctor → Click commands. In-chat commands like /plan, /cost, /rewind, /diff, /tasks operate on the live agent session.

Commands

Agent

Command	What it does
(type anything)	Send a turn to the agent
/plan	Enter plan mode (read-only); produce a numbered plan that auto-executes on approval
/plan-off	Leave plan mode without executing
/compact	Summarize older turns to free context
/summary	Print a summary without touching history
/rewind [N]	Remove the last N turns
/diff	Show files changed this session
/cost	Token + time usage so far
/tasks	Current agent TODO list
/load <model>	Swap the live model mid-session
/permissions [mode]	View or set permission mode
/chat [--resume ID]	Re-initialise the agent (or resume a session)

Hardware + models

Command	What it does
/scan	Scan hardware and show which LLM sizes fit
/scan --verbose	Include sizes that don't fit
/scan --json	Machine-readable output
/models	Browse real Ollama models with fit analysis
/models --fits-only	Hide models that don't fit
/models --ollama	Show which models are locally installed
/run [tag]	Launch a model directly in Ollama
/suggest --use-case coding	Personalised recommendation

System

Command	What it does
/doctor	Health check (hardware, Ollama, sandbox)
/memory show · /remember · /forget	Persistent per-project memory
/sessions	List resumable chat sessions
/skills	List installed agent skills
/init	Scaffold a TINILLM.md for this repo
/help	List every command
/clear	Clear the terminal
/exit	Quit (Ctrl+D also works)

Tab-completion works on every slash command, subcommand, and flag.

Plan mode

│ /plan
plan mode ON — read-only. Describe your goal.

│ add a --json flag to the scan command
Plan:
1. read render/scan.py to find the current output path
2. add --json flag in commands.py scan_cmd
3. route to a JSON renderer, gated on the flag
4. add a test in tests/test_scan_cmd.py

plan auto-accepted — executing in workspace-write mode
⚙  read_file(path='tinillm/render/scan.py')
⚙  edit_file(path='tinillm/commands.py', …)
⚙  write_file(path='tinillm/render/scan_json.py', …)
done.

Once the plan is approved, destructive bash and write-tool calls run without confirmation prompts. Autonomy is scoped to the one execution phase — the next user turn gets a fresh confirm-on-destructive policy.

---

Permissions

Three modes, set per-session:

Mode	Reads	Workspace writes	Shell	Network
read-only	✓	—	—	—
workspace-write (default)	✓	✓	confirm on destructive	—
danger-full-access	✓	✓	✓	✓

Switch mid-session with /permissions read-only.

---

Sandbox

On Linux with bubblewrap installed, every bash call is wrapped with bwrap --unshare-net --bind <workspace> / --ro-bind /usr /usr … — reads are confined to the workspace, writes can't escape it, and network is off by default. sandbox_allow_network=true in .tinillmrc opens it.

macOS / Windows: sandbox is a no-op for now; permission enforcer and workspace resolution still apply.

Check status with /doctor or the welcome panel.

---

Configuration

Per-project: .tinillmrc (TOML) in the repo root:

model = "qwen2.5-coder:14b"
permission_mode = "workspace-write"
auto_accept_plan = true
sandbox_enabled = true
sandbox_allow_network = false
allowed_tools = ["read_file", "write_file", "edit_file", "bash"]
denied_tools = []

Per-user: ~/.tinillm/settings.json (written by /load).

GPU support

Vendor	Detection method
NVIDIA	nvidia-smi → sysfs fallback
AMD	rocm-smi → sysfs fallback
Apple Silicon	system_profiler (unified memory)
Intel Arc	sysfs + lspci
Windows (all)	PowerShell WMI
Any	vulkaninfo last-resort fallback

---

Fit levels

Level	Meaning
Perfect	Fits comfortably at Q4_K_M or better with ≥20% headroom
Good	Fits but tightly
Marginal	Only at heavy compression / reduced context, or CPU-only
TooTight	Won't fit under any quantisation

---
