Contract Playbook Review is an agent skill from benchflow-ai/skillsbench. Methodology for clause-by-clause review of a contract against a structured deviation policy ("playbook"). Covers how to walk a playbook, locate the matching provision in the contract, apply rule types (max-value, must-be-present, must-be-absent, acceptable-set, must-have-feature), classify the result (ok / risk / reject), choose the prescribed action, and ground each finding in a verbatim excerpt. Use whenever reviewing any contract — NDA, MSA, vendor DD questionnaire, lease, DPA — against a structured…
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Legal & Compliance, covering Contract review. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.

Contract Playbook Review loads about 2.1k tokens when it runs. Until then it costs about 139 tokens; SKILL.md has 1,060 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/contract-playbook-review/SKILL.md (or your agent's skills folder).How a contract reviewer applies a structured deviation policy to a contract, clause by clause, and emits a structured review.
A playbook is a list of clause rules. Each rule names a clause, describes the policy in prose, and encodes the policy as machine-checkable fields (e.g. max_years, acceptable_jurisdictions, must_be_present). Review is a four-step loop, repeated once per clause:
ok, risk, or reject.Walk the playbook in order. Don't skip clauses just because the contract is silent on them — silence is itself a finding (found = false) and may trigger an action (e.g. "request_addition").
A handful of rule shapes cover almost every playbook entry. Recognise them and you can apply them mechanically:
| Rule shape | Field example | "ok" means |
|---|---|---|
| Numeric ceiling | max_years: 3, max_months: 24 | Contract value ≤ ceiling |
| Numeric floor | min_years: 1 | Contract value ≥ floor |
| Must be present | must_be_present: true | Provision exists |
| Must be absent | must_be_absent: true | Provision (or specific phrasing) does NOT exist |
| Acceptable set | acceptable_jurisdictions: [...] | Contract value ∈ set |
| Required feature | must_allow_destruction: true | Provision contains the feature |
| Conjunction of features | must_require_notice && must_require_cooperation | All features present |
| Conditional structural | must_be_bilateral_if_present | Provision absent OR present-and-symmetric |
A playbook entry may also carry a source field naming the published authority the rule is anchored to (a survey, statute, treatise, or firm-published practice guide). When the entry has a source, treat it as load-bearing — the rule's threshold is not arbitrary; it is the cited source's stated value.
Status is derived from the playbook's action_* field, not from the rule shape. This is the most common place an agent goes wrong: it sees must_be_absent and reaches for reject by reflex. Don't. Use the prescribed action to decide status — the full mapping is in the next section.
A clause may combine several rule shapes (e.g. "must be present AND have backup carve-out AND allow destruction"). The clause's overall status is ok only if every sub-rule passes.
The playbook tells you what to do when a rule fails. Translate the action to a status — never go directly from rule shape to status:
action_if_ok ("accept", "no_change") → status okrequest_ (request_reduction / request_addition / request_revision / request_change / request_amendment) → status risk. The "request_" prefix is the signal: we still want the contract; we're going to negotiate. Even a must_be_absent clause whose action_if_present is request_revision is still risk, not reject.action_if_present (or action_if_violated) of reject_and_remove / reject / walk_away → status reject. The rule's prescribed response is to refuse, not to negotiate.When the playbook is silent on a particular outcome, fall back to: action prefix request_ → risk; explicit reject/walk-away → reject.
The hard part is recognising the right clause when the contract uses different headings. Three reliable strategies:
key and label against the contract's section headings (e.g. playbook governing_law → contract heading "Governing Law" or "Choice of Law").If you searched and the contract really has nothing, set found: false and excerpt: "". Don't manufacture an excerpt, don't infer one from the playbook prose. A missing clause is a legitimate finding.
The excerpt is what proves your finding. Three rules:
found: false finding, the excerpt is "".Tip: when extracting from Markdown or plain text, copy the exact run including any quotation marks, parentheses, or numerical values. When extracting from HTML, strip tags first; do not include rendered artifacts.
One sentence. State the operative facts and the rule applied. Examples:
Avoid: hedging ("appears to", "may be"), restating the playbook in full, repeating the rationale across clauses.
clause, found, excerpt, status, action, rationale. Use empty string (not null, not missing) when the value is empty.must_be_absent rule as a numeric ceiling. If the playbook says must_be_absent: true, a 1-year non-compete still violates the rule even though "1 year" sounds reasonable — the presence matters, not the value. The violation's status then comes from the prescribed action as always: request_* → risk; only an explicit reject / walk-away action makes it reject.ok for a return/destruction clause that allows destruction but lacks the backup carve-out.© benchflow-ai, Apache-2.0.
