TESTING AND RELIABILITY / Jesse Vincent / Superpowers

Superpowers Systematic Debugging

Moves debugging from reproducible evidence through a single hypothesis to a verified fix, with a stop point for repeated failed attempts.

“Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes”

01 / THE REASONING

Why this made the selection.

  • Asks for evidence at component boundaries and backward tracing of bad values before proposing a patch.
  • Treats repeated failed fixes as a reason to revisit the architecture rather than keep layering changes.

02 / THE REVIEW RECORD

What we actually inspected.

Source review has boundaries.
A clear record is more useful than a “safe” badge.

Material inspected

  • skills/systematic-debugging/SKILL.md
  • skills/systematic-debugging/root-cause-tracing.md
  • skills/systematic-debugging/find-polluter.sh
  • LICENSE

Our findings

  • The definition separates evidence collection, working-example comparison, hypothesis testing and implementation.
  • The root-cause reference follows the origin of invalid state through callers instead of fixing only the final symptom.
  • The inspected helper detects creation of a path, not general test success; no successful debugging run is claimed here.

Not established by this review

  • Source inspection only; no skill installation or workflow execution was performed.

The review applies to the material and revision named here. A newer upstream release can change its behavior.

03 / PUT IT TO WORK

DOCUMENTED COMMAND

npx skills add https://github.com/obra/superpowers/tree/5bf4e78011075bcfc0dc295f0724994cd123ee71/skills/systematic-debugging

Copying does not execute this command. It may retrieve a newer version than the reviewed source.

  1. Install the complete skill directory with its references and helpers; a copied SKILL.md alone may be incomplete.
  2. Choose the intended agent and project scope in the installer, then review its permissions before using the skill.

Before you start

  • Node.js/npm for this installer
  • An agent that supports the Agent Skills format
  • A reproduction, relevant logs and permission to run the project’s checks
