Harness runs coding agents (Claude Code, Codex and others) as harnesses, sessions the person can watch and join in the Harness app, on this computer or their other machines. Use it to start another agent on work that can run beside yours, needs another…
Look after the models on the user's machines — one laptop or a fleet: recognise their private grid, pick the model and settings that fit this machine for coding without asking, start it with the longest context the machine can give (never under 64K), say what…
Build or update the person's About You — a short profile of how they work, from their own messages across every agent and what their agents saved about them. Use when asked to "build my About You", "update About You", "what do you know about me", or to…
Inspect Harness sessions, explain activity and resource readings, preview cleanup, and stop or open explicitly selected sessions through their owning daemons.
Reuse what LM Studio already has on this computer through its `lms` CLI: adopt its running server into the person's fleet, serve its MLX models, or serve its GGUF files without it. Load before touching LM Studio, its models or its server.
Reuse what Ollama already has on this computer: adopt a running Ollama server into the person's fleet, or serve an Ollama-downloaded model without Ollama. Load before touching Ollama, its models or its settings.
Serve an MLX or Hugging Face safetensors model already on this Mac with mlx-lm's server and join it to the person's fleet. Load before installing, starting or stopping mlx-lm, or when `fleet models` lists an `mlx` or `safetensors` model on Apple silicon.
Serve a Hugging Face model with SGLang on a Linux machine with an NVIDIA or AMD GPU, configured from the model's SGLang cookbook page — or, when it has none, from the model's own files — and join it to the person's fleet. Load before installing, configuring,…
Serve a Hugging Face model with vLLM on a Linux machine with an NVIDIA or AMD GPU, configured from the model's official vLLM recipe — or, when it has none, from the model's own files — and join it to the person's fleet. Load before installing, configuring,…
Details behind AGENTS.md's 'Starting a model on this computer' flow: reading `fleet models`, sizing a start, choosing file and engine, picking a model for an engine with none, what `fleet verify` checks, and where to read when unsure. Open it when a step of…
Use in every Trail of Bits Skills workspace inside Harness, before any audit skill — the findings.json format the report pane is built from, which Trail of Bits skill serves which audit phase, and how their plugin features (plugin root, named sub-agents,…
Model objects and scenes with Blender's Python (bpy) headless — primitives, modifiers, materials, collections, cameras, lights, animation — export glTF the 3D pane shows live, render stills and turntables, export STL. Use for any request that ends in a 3D…
Write and fix circuits in CircuitJS1's text format — the `$` options header, element lines on a 16-px grid, scope `o` lines, slider `38` lines, layout rules, and the workflow that keeps the pane moving. Use this for every circuit in this workspace, whether…
Build molecules with RDKit — from SMILES or a scaffold, analogues and series (each with its parent), properties (MW, cLogP, TPSA, Lipinski, Veber, QED, alerts), similarity and substructure search, conformer ensembles written as SDF for the pane. Use for any…
Build coordinated editable DOCX reports, formula-driven XLSX workbooks and fresh LibreOffice PDF previews from structured source. Use for Sheet & Docs Studio work.
Write a live-coded track as a Strudel pattern — mini-notation, synths, effects, song structure — and check it with the verdict. Use whenever the workspace holds a .strudel file or the user asks for a beat, a groove, a bassline, a loop, a track, or music in…
Write documents in Typst — papers, spec sheets, reports, letters, slides — compile them to PDF with the pinned typst binary, read its diagnostics, and keep the pane current. Use for any request that ends in a PDF or a printed page.
Manage the machines on a Harness account by conversation — read the fleet, link and unlink, rename, note and group, bring a new computer in, remove one. Use in a Machine Monitor workspace whenever the person asks about their computers, what is running on…
Turn home-automation requirements into editable Home Assistant YAML, tested what-if scenarios, native Core traces and a reviewed installation kit in Habitat. Use for automation authoring and revision, not unrequested device control.
Plan real experiments and analyze supplied continuous measurements in Lab Bench. Use for defining factors and independent runs, randomized collection sheets, measurement CSV imports, experimental uncertainty and diagnostics, comparisons and follow-up…
Create and revise original board or card games from a person's idea, with editable mechanics and components, real human playtests, reproducible simulations and a complete playable and printable kit. Use for tabletop game design, card drafting, cooperative…
Run a decision through a panel of coding agents from different vendors — writing the motion, seating the room, the sealed-openings protocol, tagging the claim map, pressing a split, and writing a decision that picks and keeps its dissent. Read before opening…
Create and revise field-survey plans from supplied GeoJSON boundaries, exclusions, camera geometry and capture requirements. Use Drone Pilot for editable routes and sorties, recorded-flight CSV analysis, and portable GIS, CSV and report delivery.
Turn a user's brief into an editable voxel environment or asset kit in Voxel Worlds. Use for original scene design, modular assets, terrain sculpting, walkable spaces, importing VOX assets and delivering GLB/VOX files with an offline studio.
Turn a musical brief into editable concert-pitch music, checked instrument parts and a listenable practice pack in the Score harness. Use for composing, arranging and revising trusted LilyPond projects.
Turn user CSV files and a question into a typed, joined, repeatable local SQLite analysis with traceable records, browser revisions and verified portable exports.
Create and revise a usable brand identity and coordinated launch materials from a business brief, using the Forme project and the person's own artwork, text and production requirements.
Turn a user's STL and explicit machine/material requirements into compared OrcaSlicer plans, editable 3MF projects, checked G-code and a portable handoff. Use for Orca Slicer harness work.
Create original vector artwork and complete visual asset sets from a person's brief, with custom drawing programs, user-editable controls and real SVG/PNG/source delivery.
Compose and revise complete original music from a brief or the user's MIDI and recordings, with editable notes, arrangements and real WAV/stem/MIDI/project delivery.
Turn measured design briefs or existing parts into editable FreeCAD projects with checked dimensions, bores, clearances, interference and fastener access; deliver separate STEP/STL parts, reference drawings and a portable project handoff.
