auto-claim

auto-claim is a skill for Claude Code from zjunlp/Mechanist. It costs 298 tokens per session (14,914 once invoked), scanned A, original, MIT.

A workflow skill for turning a research task into a tested claim about observed behavior and the mechanism that may cause it.

In plain words
What is it for?
Running claim-stage research pipelines, validating proposed phenomena, choosing or discovering mechanisms, and coordinating the required research and experiment phases.
Why use it?
It organizes whether the behavior and explanation are accepted or need validation and discovery before research and experimentation proceed.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is - **[Output Versioning Protocol](../shared-references/output-versioning.md)** — write timestamped file first, then copy to fixed name.

SkillSpector: 2 findings, up to high

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 →

  • high Tool Misuse · line 88
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
  • medium Excessive Agency · line 648
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

auto-claim 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 8d 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.

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.

Workflow 1: Claim Stage — Behavior (given / given-validation / discovery) × Mechanism (given / discovery)

Orchestrate the claim stage for: $ARGUMENTS. Two orthogonal constants drive everything: BEHAVIOR_SOURCE (where the behavior comes from + whether it is validated) and MECHANISM (who picks the mechanism method).

Overview

This skill chains sub-skills into a single automated pipeline. All combinations share Phases 0, 0.5, 1, 4.5, 5, and 5.5; they differ in how the claim(s) entering Phase 4.5 are produced (Phase 2 + the ideation Phases 3/3.5/4) and in what Phase 1.75 loads.

Behavior stage — BEHAVIOR_SOURCE decides the behavior origin, whether ideation runs, and whether the plan opens with an M0 phenomenon-validation gate:

  • given (default) — the behavior is already specified in the direction / task.md and assumed to hold. Faithfully capture it (no ideation, no novelty, no M0) and go straight to the mechanism:
    /research-lit → faithful behavior capture (from task.md) → /research-refine-pipeline
    
  • given-validation — the behavior is captured the same way (no mining, no ideation, no novelty) but its existence is validated first: the experiment plan opens with a hard M0 gate that the experiment stage runs before any mechanism compute.
    /research-lit → faithful behavior capture (from task.md) → /research-refine-pipeline (plan opens with M0)
    
  • discovery — the behavior itself is mined: /mechanism-behavior-discovery sharpens a new candidate phenomenon, then full ideation generates and ranks mechanistic ideas; the plan opens with the M0 gate too.
    /research-lit → /idea-creator → /novelty-check → /impact-check → /research-review → /research-refine-pipeline
      (survey)      (brainstorm)    (verify novel)   (verify it     (critical feedback)  (refine method + plan)
                                                      matters)
    
    The final idea is selected by combined impact + novelty, with impact weighted first (a less-novel idea on an important problem outranks a novel idea nobody needs).

auto-claim is a skill published in the GitHub repository zjunlp/Mechanist (72 stars, last pushed 12d ago), licensed MIT. It adds 298 tokens to every session and 14,914 once invoked, about $0.0015 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
