LedgerSkills

Security-vetted Claude Code skills for audit, tax, FP&A and accounting. Tested on real files. No mystery code.

LedgerSkills is a curated marketplace of agent skills for finance professionals using Claude Code and claude.ai. Every listing is:

• Hand-reviewed — we read every line before listing it
• Security-scanned — invisible-Unicode injection checks, prompt-injection lint, executable inventory (methodology)
• SHA-pinned — third-party skills are pinned to the exact reviewed commit; upstream changes go back into review, never auto-shipped
• Actually tested — we run each skill on realistic files and publish the verdict

⚠️ Every skill here is a drafting and analysis aid, not professional advice. Output must be reviewed by a qualified professional. Scan scores mean "scanned", not "safe".

In Claude Code:

/plugin marketplace add OWNER/ledgerskills
