finance-automation-portfolio: Skill for Claude Code

.claude/skills/validate/SKILL.md

validate is a skill for Claude Code from sophonfinance-wq/finance-automation-portfolio. It costs 42 tokens per session (198 once invoked), scanned A, original, MIT.

A read-only validation tool for auditing finished spreadsheet workbooks. It reports PASS, REVIEW, or FAIL results and checks that the files remain byte-for-byte unchanged.

In plain words
What is it for?
Use it to audit workbook sets, inspect planted defects, run the validation test suite, and confirm that an audit has not changed any workbook bytes.
Why use it?
It detects workbook defects without modifying the files being audited. If a problem is found, the producing system must fix it before validation is run again.

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

validate 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.

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

Validation Engine (read-only)

Package validation_engine in audit-automation/.

Commands (run from audit-automation/)

python run.py                 # audits the workbook set read-only; prints PASS/REVIEW/FAIL per book
python -m pytest -q           # 4,814 tests incl. planted-defect suite

The one rule

This engine NEVER writes — workbooks open read_only=True and the suite asserts sha256 byte-identity after a run. Do not bolt a remediation loop onto it; it is the sensor other loops use. If asked to "fix" what it finds, route fixes through the producing engine, then re-validate.

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.
