dsh-contract-stance

Boundary: this plugin checks a 合同条款立场台账 for what a register can be held to — that each clause's text is recorded, that your stance comes from your vocabulary, that the risk grade does too, that a must-have clause records both a fallback position and an owner, that clause numbers are unique, that the register names the contract and your side, and that no placeholder survives. It does not decide whether a clause should be accepted, whether a risk is bearable, whether to sign, or whether a negotiating strategy is sound. Those depend on the deal, the counterparty's leverage and your own risk appetite.

⚠️ What the citation rests on — and one thing this plugin must never be given

《中华人民共和国民法典》was obtained and read verbatim, and rules/evidence/clause-verification.md records what was quoted: article 465 (a contract lawfully formed is protected by law), article 470 (contract content 一般包括 the parties, subject matter, quantity, quality, price, performance terms and liability for breach), article 509, article 577 (the consequences of breach) and article 584 (damages include expected profits but are capped by foreseeability).

The contract part does not regulate a negotiation register. It governs formation, validity, performance and liability; the register's columns come from your enterprise's own contract management rules. So the excerpt fields still say "本次未取得" and every rule stays warn or info: "this column is blank" must not be read as "this breaches the Civil Code". Note also that article 470 says 一般包括, not 应当包括 — one more reason CS-001 does not claim a direct obligation.

⚠️ Do not add a limitation-period rule to this plugin. The Code does fix numbers — article 188 sets a three-year limitation (twenty years at the outside) and article 203 rolls a period forward off a public holiday — which makes "just compare the dates" look tempting. It is not workable here: the period runs from when the creditor knew or ought to have known of the harm and the debtor, a finding of fact the register does not record; the period is also subject to suspension (article 194) and interruption (article 195), and article 196 lists claims the limitation does not apply to at all. A date-arithmetic rule would dress a factual finding up as a calculation, which is precisely the over-claim this family avoids.

No judgement about the substance of a clause is made anywhere in this plugin. It reads your own columns and checks only that they are filled and drawn from your vocabulary. Two vocabularies ship empty — the stance list (CS-002) and the risk grades (CS-003) — so with nothing configured those rules report themselves in skipped rather than passing quietly.

Compatibility

Surface	Status
Harness	Peer range >=0.1.2-rc.1 <0.2.0 || >=0.2.0-0 <0.3.0 — verified to accept both 0.2.0-rc.2 and 0.2.1-alpha.1. engines.dsh is deliberately not declared: it has no reader and cannot reject a host
Node	`^22.19.0
Platforms	All (plain ESM; no native code, no network, no model call)
Tool mode	Works in native, ptc and both; for a full contract use ptc

What it does

Registers the contract_stance tool. It reads one clause-position register — the contract header plus one row per clause — applies a versioned rule pack, and returns a report.

Rule	Check	Severity	Basis kind
CS-001	every clause's text is recorded	warn	principle
CS-002	the stance comes from your vocabulary (off by default)	info	local
CS-003	the risk grade comes from your vocabulary (off by default)	info	local
CS-004	a must-have clause records a fallback and an owner	warn	principle
CS-005	clause numbers are unique	warn	principle
CS-006	the register names the contract and your side	warn	principle
CS-007	the clause text holds no unreplaced placeholder	warn	principle

Install

dsh plugin --profile <name> add dsh-contract-stance
dsh --profile <name> --dump-config | grep 'dsh-contract-stance'

Configuration

Key	Type	Default	Description
rulesFile	string	rules/contract-stance.yaml	Rule-pack path, relative to the package root
disabledRules	string[]	[]	Rule ids to stop running; each appears in skipped
onlyRules	string[]	[]	Run only these rule ids; empty runs every rule
skipNotes	string	""	Note appended to every skipped reason
timeoutMs	number	120000	Cooperative tool timeout budget

Rule-level parameters worth knowing:

• CS-002 values — your stance vocabulary, e.g. [坚持, 可谈, 接受, 须删除]. Empty means no check.
• CS-003 values — your risk grades, e.g. [高, 中, 低]. Empty means no check.
• CS-004 conditionValues — the values in your 是否必保 column that mark a clause must-have, by default [是, Y, yes, true, 必保, √].
• CS-007 terms — the placeholders to look for.

Material format

The tool accepts JSON or YAML:

contractNo: HT-2026-018
contractName: 某某设备采购合同
party: 某某公司
version: 第 3 轮谈判稿
rows:
  - { 条款号: 第 8.2 条, 条款主题: 逾期付款违约金,
      条款原文: 买方逾期付款的，每逾期一日按未付金额的万分之五向卖方支付违约金。,
      本方立场: 可谈, 风险等级: 中, 风险说明: 违约金比例高于本方惯例且未设上限,
      退让底线: 比例可降至万分之三，须增加总额不超过合同额 5% 的上限,
      是否必保: 是, 谈判责任人: 王经理 }

Column names are matched case-insensitively and ignoring spaces, underscores and hyphens; the register's own column names are kept, so a finding names the column it read.

Rule sources

Rule data lives in rules/contract-stance.yaml. The pack's header states the citation gap in full, and each rule's note repeats the part that matters for that rule. The load-time guard that normally enforces "an excerpt must be a real quotation of at least eight characters" cannot tell a quotation from a description — so this pack leans on the header, the per-rule notes and a test that asserts every excerpt admits the gap.

Troubleshooting

• CS-002 or CS-003 reports itself as skipped. Its vocabulary is empty. Stance and risk wording is your institution's convention, and the plugin will not guess it.
• CS-004 fires on a clause marked must-have. It records no fallback or no owner. A must-have clause without a stated floor cannot be negotiated on the spot.
• CS-001 fires although the clause is quoted elsewhere. The text column itself is empty. The check reads the register, not the contract document.
• CS-005 fires on one clause twice. That is legitimate across negotiation rounds — distinguish the rows in the version column rather than reusing the clause number.
• The plugin installs but the tool never appears. Check that main resolves to lib/index.mjs and that pnpm run build produced it; a wrong main makes the loader skip the entry silently.
• dsh plugin add refuses the package as incompatible. The peer range covers 0.1.x and 0.2.x; if your runtime sits outside it, grant an explicit exemption: dsh plugin --profile <name> allow-version dsh-contract-stance@0.1.0 --dsh-version <runtime> --accept-risk
• check reports manifest-peers as failed. The static checker compares against a hard-coded peer range that predates the 0.2 line. The runtime enforces peer compatibility at install time, so the declared range is the correct one; this is a known upstream issue in dsh-plugin-dev.

Development

pnpm install
pnpm run typecheck   # tsc --noEmit
pnpm test            # vitest, the shared table-plugin suite plus paired fixtures
pnpm run build       # tsdown -> lib/index.mjs + lib/index.d.mts
node ../scripts/sync-shared.mjs dsh-contract-stance   # refresh src/shared from ../_shared

The plugin is data-only: src/model.ts declares the table shape, the shared kit supplies the reader and the check engine, and the rule pack declares every check.
