source-verification

source-verification is a skill for Claude Code, Codex from rebel0789/Memory-Recall. It costs 0 tokens per session (97 once invoked), scanned A, original, Apache-2.0.

A procedure for checking important claims against cited evidence and source details. It labels claims as supported, weak, conflicting, outdated, or unsupported.

In plain words
What is it for?
Use it to verify research findings, reports, and other material claims by checking their evidence, timing, authority, and exact wording.
Why use it?
It helps identify statements that lack reliable support or rely on sources that are old, unclear, or in conflict.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

source-verification scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Source Verification

Purpose

Verify material claims against available evidence.

Procedure

  1. List each material claim.
  2. Resolve cited evidence IDs and source metadata.
  3. Check time, authority, conflict, and exact support.
  4. Mark supported, weak, conflicting, stale, or unsupported.

Completion

Return evidence, files changed when applicable, exact checks, risks, limitations, rollback, and safest next step. The skill never grants a tool or broadens policy.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
