What is tabular-review?

A batch document-review workflow that puts one document per row and one requested fact per column, with every answer linked to a source quote and location. It is designed for checking many contracts or other documents consistently.

Use it for M&A diligence, such as reviewing contracts for change-of-control, assignment, or material-adverse-change clauses, and for other source-cited batch reviews.

Reviewing a large set of documents manually can produce inconsistent notes and hard-to-verify conclusions. This creates a structured spreadsheet and shows which results need further checking.

tabular-review — Skill for Claude Code by anthropics/claude-for-legal

About the project

Claude for Legal is a collection of AI agents, skills, and data connectors for legal work such as commercial, privacy, employment, litigation, regulatory, and intellectual-property matters. Lawyers and legal teams use it through Claude Cowork, Claude Code, or the Claude Managed Agents API, with attorney review required for every output. The catalogue entries are its workflow plugins, skills, agents, and connectors.

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 Anti-Refusal · line 156
Skill instructs the agent to never refuse or to always comply. Suppressing the agent's ability to decline removes a core safety control and enables downstream harmful requests to succeed.

Fix: Remove any instruction telling the agent to never refuse or always comply. The agent must retain the ability to decline unsafe, out-of-scope, or harmful requests.
medium Rogue Agent · line 44
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00124	$0.04039
Opus 5.5	$0.00050	$0.01616
Sonnet 5.5	$0.00025	$0.00808
Haiku 4.5	$0.00012	$0.00404

Security

Grade A, and why

tabular-review 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 236 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/tabular-review

Load ~/.claude/plugins/config/claude-for-legal/corporate-legal/CLAUDE.md → diligence structure, thresholds, house format.
Confirm: what documents, what columns, where does the output go.
Build the typed schema. Write .review-schema.yaml. Confirm with the user.
Sample run (3–5 docs). Adjust schema. Confirm.
Fan out — one sub-agent per document, parallel. Each cell: value + state + verbatim quote + location.
Normalization pass. Flag outliers and inconsistencies.
Output: .xlsx or Google Sheets (ask which), plus .csv + _sources.csv + markdown always. Work-product header.
Summary: verification workload (counts of not_present / unclear / needs_review per column), flagged columns, where the files are, reminder that every cell is a lead not a finding.

/corporate-legal:tabular-review --schema .review-schema.yaml --docs ./vdr/02-Contracts/

--schema <path>: Use an existing schema file instead of building one. Useful for re-runs and incremental additions.

--template <name>: Start from a template in references/. Currently: ma-diligence.

--docs <path>: Document source. A local folder, a Drive folder ID, or a VDR path. If omitted, asks.

--output <xlsx|gsheets|csv>: Output format. If omitted, asks.

--sample <n>: Sample size for the schema check. Default 5.

Matter context

Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /corporate-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/corporate-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.

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.
