esg-report-auditor is a skill for Claude Code, Codex from aragaobruno/toolbelt. It costs 66 tokens per session (921 once invoked), scanned A, original, MIT.

A skill that audits environmental, social, and governance reports against reporting frameworks such as CSRD/ESRS, GRI, SASB, and TCFD. It also checks whether sustainability claims have supporting evidence and flags possible greenwashing.

In plain words
What is it for?
Use it to review sustainability reports, ESG sections of company filings, or supplier claims. It assesses disclosure coverage, quantitative baselines, and the strength of supporting evidence.
Why use it?
It helps reveal missing disclosures, weak evidence, and claims that sound environmental or social but cannot be properly verified.

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

esg-report-auditor 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/audit_report.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

📑 ESG Report Auditor & Greenwashing Forensic Skill

This skill equips AI agents with SRE-grade forensic audit capabilities for corporate Sustainability and ESG (Environmental, Social, Governance) disclosures. It evaluates text and data artifacts against international reporting frameworks (CSRD/ESRS, GRI, SASB, TCFD), quantifies claim verifiability, and detects greenwashing patterns.


🎯 When to Activate This Skill

Activate this skill when:

  • Reviewing corporate sustainability reports, ESG disclosures, or 10-K environmental sections.
  • Auditing vendor or supplier ESG claims for greenwashing risks.
  • Checking disclosure alignment with CSRD (Corporate Sustainability Reporting Directive), ESRS, GRI, or SASB standards.
  • Assessing Double Materiality assessments and verifying quantitative baseline claims.

🔍 Audit Methodology & Core Metrics

1. Claim Classification Matrix

Every environmental or social assertion in a document must be categorized into one of four rigor tiers:

Tier Category Definition & Verification Criteria
T1 Substantiated Metric Quantitative target tied to a base year, scope boundaries, and third-party assurance.
T2 Third-Party Assured Claim certified by an accredited audit body (e.g., ISO 14064-3, ISAE 3000).
T3 Unsubstantiated Metric Quantitative claim lacking baseline year, denominator, or methodology.
T4 Vague / Greenwashing Aspirational prose using buzzwords ("eco-friendly", "carbon-neutral by 2050") without milestones.

2. Greenwashing Risk Score (GRS)

Calculated deterministically using claim density and vagueness indices: $$GRS = \left( \frac{\text{T3 Claims} \times 1.5 + \text{T4 Claims} \times 2.0}{\text{Total Claims}} \right) \times 100$$

  • 0.0 - 25.0: Low Risk (High substantiation, audit-ready).
  • 25.1 - 50.0: Moderate Risk (Contains aspirational statements without baselines).
  • 50.1 - 75.0: High Risk (Preponderance of unverified buzzwords).
  • 75.1 - 100.0: Critical Greenwashing Alarm (High probability of deceptive disclosure).

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.
