evidence-ledger

evidence-ledger is a skill for Claude Code from wanshuiyin/Anti-Autoresearch. It costs 221 tokens per session (11,987 once invoked), scanned A, original, MIT.

An evidence-building skill for research audits. It inventories available files, determines whether the evidence is only a PDF or also includes LaTeX, source code, and results, then creates hashed, checkable records linking claims to exact document spans.

In plain words
What is it for?
Use it as the first step when auditing a research project or paper for whether its claims are supported by the available files.
Why use it?
It gives later auditors one consistent, traceable set of source records instead of making each auditor reread documents and produce conflicting numbers or tables.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

evidence-ledger scanned grade A with 1 finding 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 13d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 638 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Evidence Ledger — the spine every auditor reads

Infrastructure skill, not an auditor. It produces the only structure the auditor skills are allowed to reason over, so they don't each re-read the PDF and hallucinate a different table and a different list of numbers. It emits no findings and no verdict — only artifact_manifest.json + claims.json. See references/integrity-forensics-contract.md §"The pipeline" (stages [1]–[2]).

Build the ledger for: $ARGUMENTS

🔁 Not verdict-bearing — but not a polling skill either. The deterministic backbone (Steps 1–2) is a pure function of the hashed sources: same source bytes → byte-identical claims.json. Re-run it only when the sources change, never on a wall-clock timer. The only non-deterministic part is the optional enrichment pass (Step 3), which is additive and skippable. Do not wrap this skill in /loop / /schedule / CronCreate; there is no verdict to re-fire and no external event to wait on.

Why this exists

Five language-model auditors each independently parsing a PDF = five different hallucinated tables and five different number lists, none reproducible — and the obvious dismissal, "an LLM grading another LLM's paper is just slop." The structural answer is one deterministic pass that turns the paper into:

  • artifact_manifest.json — what was observable; this fixes the observability level L, the ceiling on every downstream finding's severity, and
  • claims.json — a list of span-anchored, hashed, checkable claims (schemas/claims.schema.json).

Every downstream finding must cite a claim_id from this ledger and quote a verbatim span of it. No ledger claim → no finding (the single most important integrity rule of the repo, enforced again by tools/adjudicate_findings.py). That is what makes the difference between "a model said so" and "here is the exact sentence, its file, and its content hash" (DESIGN.md §2).

evidence-ledger is a skill published in the GitHub repository wanshuiyin/Anti-Autoresearch (153 stars, last pushed 3d ago), licensed MIT. It adds 221 tokens to every session and 11,987 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
