Teaching Agents New Tricks via Agent Skills

A presentation and technical exploration by Brett Morgan categorizing how Agent Skills (following the agentskills.io open specification) are authored, generated, and applied in practice—using the reverse-engineering of embedded firmware for the this.is.NOISE Gamma mini synth (powered by an Electro-Smith Daisy Seed 2 DFM) as a real-world case study.

The "Three Ways" Taxonomy

When reverse-engineering the Gamma mini synth without schematics or source code, seven custom Agent Skills emerged across three distinct authoring patterns (plus a capstone mashup):

  1. Way 1: Library Review Skills

    • libdaisy-guide & daisysp-guide
    • Created by having an agent inspect C++ library source trees (libDaisy and DaisySP), synthesize architectural and real-time DSP reference reports, and package those findings into reusable skills.

  2. Way 2: DFU Operational Skills

    • gamma-firmware-flash & gamma-firmware-restore
    • Created by solving USB-C dfu-util bootloader flashing requirements (BOOT_SRAM 0x24000000 vector table relocation and the ~2.5s Daisy bootloader grace window) and wrapping the workflow into deterministic Python scripts and operational runbooks.

  3. Way 3: Hardware Discovery Skills

    • gamma-pinout & gamma-hardware-controls
    • Distilled from a phased series of interactive diagnostic firmwares that mapped physical pins, ADC channels, polarities, and C++ driver idioms for the 14 tactile keys, 4 potentiometers, 2 dual-axis thumbsticks, rotary encoder, and SSD1306 OLED display.

  4. The Capstone Mashup Skill

    • gamma-usb-connectivity
    • Combines all three patterns into a single skill package: discovered USB pinout facts (UsbHandle::FS_EXTERNAL on D29/D30), a deadlock-immune C++ firmware driver (gamma_usb.h), and a host-side Python communication utility (gamma_usb.py).

Repository Structure

  • slides/ — Slidev presentation deck, custom Vue components, layouts, and acts (01-primer.md through 06-experiment-and-conclusion.md).
  • .agents/skills/ — Agent Skills packages used both in the Gamma mini synth case study and for authoring/maintaining this repository.
  • terminal-recordings/ — Sanitized asciinema .cast recordings embedded in the presentation.
  • GLOSSARY.md — Canonical project terminology and domain language.

Running the Slide Deck Locally

The presentation is built with Slidev (Vue 3 + Vite).
