2 things to look at

  • 17 days oldThe repository was created 17 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
  • 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Verify the sources supporting the current HACP Working Object, distinguish direct evidence from inference and unknowns, and append a sources-checked annotation without replacing the object. Use only when the user invokes CHECK SOURCES or explicitly asks to verify the current sources.

📚 Check Sources

ID: reality-check/check-sources
HACP: 0.4
Kind: operation
Mode: annotate
Traits: read-only, evidence-annotation, source-verification
Default Binding: Claims and sources in the current object or request
Accepts: hacp/content, hacp/result
Produces: hacp/result, preserving the input kind and content and adding reality-check/sources-checked with traits evidence and source-evidence
Duration: once

Effect: Verify material claims against the best allowed sources and append a scoped evidence annotation without replacing the current object.

Check

  1. Identify only the claims whose truth matters to the object's use.
  2. Inspect the cited or best allowed primary sources. Revalidate time-sensitive claims.
  3. Mark each material claim supported, partial, contradicted, unverified, or inference.
  4. Append source identity, freshness, access limitations, resolved Binding, traits, and source. Preserve the object's Binding, status, kind, content, and existing annotations.

Honor active controls before access. When external access is blocked, consult only local files, cached artifacts, command output, and conversation context; mark remote claims unverified locally. Never name or depend on the card that established the control.

Limits

  • A plausible statement is not evidence.
  • A secondary source cannot silently stand in for an available primary source.
  • Never fabricate citations, quotes, dates, or tool observations.

Format

Contribute → 🔎 **CHECK SOURCES** to the one complete combo trace, or begin with > 🎯 **<binding>** → 🔎 **CHECK SOURCES** when used alone. Then use Sources for the material classifications. Never emit a second trace or deck-status line.

Grouped from the skills themselves: near-identical wordings counted once, and counted by distinct author, so one author publishing three of these counts once. Length counted with cl100k_base; the agent that loads this file may tokenize it differently.
