What it does
Clause Risk Database is an agent skill from revfactory/harness-100. A risk clause database that systematically identifies and grades risk patterns in contract clauses. The 'risk-assessor' and 'clause-analyst' agents must use this skill's pattern DB and scoring methodology when evaluating clause-level risk in contracts. Used for clause-level risk assessment tasks such as 'risk clause analysis', 'disadvantageous clause identification', 'risk scoring', etc. Note: Overall contract orchestration or contract drafting itself is outside the scope of this skill.
Its SKILL.md is about 1.5k 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 licence is Apache-2.0.
When your agent uses it
- Tasks that involve Contract review
Example prompts
- “risk-assessor”
- “clause-analyst”
- “risk clause analysis”
- “/clause-risk-database”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Clause Risk Database loads about 1.5k tokens when it runs. Until then it costs about 128 tokens; SKILL.md has 477 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.
Safety
Auto-check passed
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.

Clause Risk Database — Risk Clause Pattern DB and Scoring Engine
A specialized knowledge base that identifies risk patterns in contract clauses and calculates quantitative risk scores.
Risk Clause Pattern Classification System
Tier 1: Critical Risk (80-100 points)
| Pattern ID | Pattern Name | Description | Representative Wording |
|---|---|---|---|
| C-01 | Unlimited Liability | Full liability without cap | "shall indemnify all damages" |
| C-02 | Unilateral Termination | Only the counterparty can terminate unconditionally | "Party A may terminate immediately without cause" |
| C-03 | Blanket Indemnification | Complete exemption of counterparty's liability | "Party A shall not be liable under any circumstances" |
| C-04 | Unlimited IP Transfer | Transfer of all IP without consideration | "All rights to deliverables shall vest in Party A" |
| C-05 | Excessive Non-Compete | Non-compete with excessive scope in duration, geography, and range | "Prohibited from working in the same industry for 2 years" |
Tier 2: High Risk (60-79 points)
| Pattern ID | Pattern Name | Description | Representative Wording |
|---|---|---|---|
| H-01 | Auto-Renewal Trap | Excessive notice period + automatic renewal | "Auto-renews for 1 year without 60-day prior notice" |
| H-02 | Excessive Delay Penalties | Delay penalty rate exceeding market standard | "1% of contract amount per day of delay" |
| H-03 | Infinite Acceptance Loop | No limit on acceptance review count/duration | "Revisions shall continue until Party A is satisfied" |
| H-04 | One-Sided Confidentiality | Confidentiality obligation imposed on one party only | "Party B shall not disclose the contents of this contract" |
| H-05 | Unfavorable Jurisdiction | Exclusive jurisdiction at counterparty's location | "Court at Party A's headquarters location" |
Tier 3: Medium Risk (40-59 points)
| Pattern ID | Pattern Name | Description |
|---|---|---|
| M-01 | Delayed Payment | Payment terms exceeding 60 days after acceptance |
| M-02 | Unlimited Change Requests | Lack of cost adjustment provisions for scope changes |
| M-03 | Unclear Completion Criteria | Ambiguous completion/acceptance standards |
| M-04 | Excessive Warranty Period | Warranty period exceeding industry standard |
| M-05 | Unspecified Governing Law | Unclear governing law in international transactions |

Tier 4: Low Risk (20-39 points)
| Pattern ID | Pattern Name | Description |
|---|---|---|
| L-01 | Insufficient Notice Provisions | Absence of written/email notification rules |
| L-02 | No Assignment Restriction | Absence of restrictions on transfer of contractual rights/obligations |
| L-03 | Missing Force Majeure | Absence of force majeure exemption clause |
Risk Scoring Algorithm
Individual Clause Score Calculation
clause_score = base_score(pattern) x position_weight x contract_size_weight x industry_weight
position_weight:
- Party A (advantaged side): 0.5
- Party B (disadvantaged side): 1.5
- Neutral/Unknown: 1.0
contract_size_weight:
- Under 100M: 0.8
- 100M-1B: 1.0
- 1B-10B: 1.3
- Over 10B: 1.5
industry_weight:
- IT/Software Development: 1.2 (IP risk)
- Construction: 1.3 (delay penalties, warranty)
- Finance: 1.4 (regulatory risk)
- General Services: 1.0Overall Risk Grade
overall_score = sum(weighted_clause_scores) / total_clause_count
Grades:
S Grade (Immediate Correction): Overall 80+ or 1+ Critical clauses
A Grade (Correction Recommended): Overall 60-79
B Grade (Caution): Overall 40-59
C Grade (Satisfactory): Overall 20-39
D Grade (Excellent): Overall under 20Required Checkpoints by Contract Type
Software Development Services
| Essential Clause | Risk if Missing | Recommended Standard |
|---|---|---|
| IP Ownership | IP dispute | Joint ownership or license |
| Source Code Delivery | Vendor lock-in | Escrow or direct delivery |
| Change Management (CR) | Scope creep | CR process specified |
| Acceptance Criteria/Period | Infinite revisions | Within 2 rounds, 14-day deadline |
Lease Agreement
| Essential Clause | Risk if Missing | Recommended Standard |
|---|---|---|
| Deposit Return Conditions | Non-return | Within 30 days after vacating |
| Restoration Scope | Excessive restoration costs | Exclude normal wear and tear |
| Early Termination Terms | Penalty disputes | 3 months prior notice |
NDA (Non-Disclosure Agreement)
| Essential Clause | Risk if Missing | Recommended Standard |
|---|---|---|
| Confidential Information Definition | Scope dispute | Marking/labeling approach |
| Duration | Infinite obligation | 2-3 years |
| Exceptions | Excessive restrictions | Public info, independent development, court orders |
Risk Report Output Format
## Contract Risk Scorecard
**Contract Type**: [Type] | **Party Position**: [A/B] | **Overall Grade**: [S/A/B/C/D]
| # | Clause | Pattern | Grade | Score | Modification Recommendation |
|---|--------|---------|-------|-------|-----------------------------|
| 1 | Article X | C-01 | Critical | 95 | Liability cap required |Notes
