Spec score 7.5 #24 of 26 in Infographic Makers

What it is

Signal Loom is an open-source local skill package for turning research materials into evidence-traceable infographics. It accepts reports, notes, datasets, interviews, or existing infographics together with an intended audience and purpose. The default result is a semantic, responsive web infographic; an approved story can be reconstructed for carousels or other requested formats. Each project creates a Loomfile folder containing evidence, claims, story, visual plan, infographic, review records, and checkpoints. Its workflow runs through ORIENT, SHAPE, PLAN, BUILD, FINISH, DISTRIBUTE, and VERIFY. The repository documents Codex and Claude Code as host environments, with installation by cloning the repository into the host’s personal skills directory. Included Python tools use the standard library, make no network calls, and contain no telemetry. Signal Loom does not independently verify truth, refresh facts without authorization, approve its own work, or publish artifacts. Static checks cannot establish factual accuracy, accessibility, security, or professional fitness.

Strong points and limits

Strong points

  • Open-source MIT-licensed package
  • Evidence and claims stored in Loomfiles
  • Semantic responsive web infographic output
  • Works with Codex and Claude Code
  • Python tools make no network calls

Limits

  • Does not independently verify claims
  • Does not publish artifacts on its own
  • Static checks are not security assessments
  • AI host may transmit files under its terms

Who it suits

It suits people who need a local, resumable process for building evidence-linked infographics from supplied material. Users of Codex or Claude Code are the documented host audience.

Verdict

Signal Loom structures infographic work around traceable evidence, staged production, and review records. It remains a local skill package: users provide the material and approvals, while factual, security, accessibility, and publication decisions remain outside its automated validation.
