Negotiate terms and review contract provisions

Negotiate

Convert the selected vendor's evaluated position into agreed contractual terms — pricing, SLAs, exit provisions, data handling, liability, IP. The output is the master record of what the organization and the vendor agreed to; the downstream stages execute against it.

Scope

Term negotiation and risk review: settling commercial terms, defining SLAs with measurable thresholds, and reviewing the risk clauses (exit, IP, data, liability) for legal and commercial exposure. Negotiate decides what both parties commit to — not which vendor was chosen (evaluate) or standing the relationship up operationally (onboard).

What to do

  • Negotiate commercial terms and SLAs with measurable thresholds, not aspirational language no one can enforce.
  • Review risk clauses (exit, IP, data, liability) and categorize each by legal vs commercial exposure with recommended language.
  • Keep the terms document authoritative — onboard and monitor compare against exactly what's recorded here.
  • Surface non-standard terms for the right approval authority rather than absorbing them quietly.

What NOT to do

  • Don't re-score or re-shortlist vendors — a flawed selection is a revisit to evaluate.
  • Don't provision accounts or wire integrations; that's onboard.
  • Don't agree to an SLA without a measurable threshold behind it.
  • Don't leave a negotiated term out of the master record that downstream stages depend on.

Negotiation Terms

Agreed commercial terms, contract review results, and SLA definitions.

Content Guide

Structure the terms document for onboarding and ongoing management:

  • Pricing and payment -- agreed pricing, payment terms, and discount structures
  • SLA definitions -- measurable thresholds, measurement methods, and remedies for non-compliance
  • Contract provisions -- key terms including duration, renewal, exit, liability, and indemnification
  • Risk review -- legal review findings with accepted, modified, or rejected provisions
  • Data handling -- data privacy, security, and compliance provisions
  • Comparison -- agreed terms compared to initial positions and market benchmarks

Quality Signals

  • SLA terms include measurable thresholds with enforceable remedies
  • Exit provisions protect against vendor lock-in
  • Legal review findings are resolved or risk acceptance is documented
  • Data handling provisions comply with applicable regulations

Mandate: The agent MUST verify the negotiated terms adequately protect the organization's interests across the full life of the contract, not just at signing. Gaps here become unbounded exposure later — operational, financial, regulatory, reputational.

Check

The agent MUST verify, file feedback for any violation:

  • SLA thresholds with measurement and remedies — Every SLA term includes a measurable threshold, a named measurement method, an exclusion list with rationale, and a real remedy (service credit ladder, escalation, termination right after sustained breach). SLA language without remedies is marketing, not contract.
  • Exit provisions adequate — The contract names data export format and timeline, data deletion with attestation, transition assistance, and either a termination-for-convenience right or a clearly bounded set of termination-for-cause triggers. Vendor lock-in disguised as a long contract is reject-worthy.
  • Data handling and privacy compliant — Data classification, residency, retention, deletion, breach notification, subprocessor consent, and cross-border transfer mechanisms are addressed and align with the applicable regulatory regime.
  • Material risk clauses reviewed — Liability caps, indemnification scope, IP ownership (including data and any derivative work), confidentiality, audit rights all have either acceptable language or documented risk acceptance with named owner.
  • Renewal mechanics fair — Auto-renewal (if present) has an explicit notice window and a price-cap on renewal. Open-ended renewal escalators are reject-worthy.
  • Trade-offs documented — Each concession is named with what was traded for it; silent concessions leak value.

Common failure modes to look for

  • An SLA section that uses adjectives ("high availability", "responsive support") instead of measurable thresholds
  • An SLA with thresholds but no remedy, or a remedy capped so low it doesn't change vendor behavior
  • An auto-renew clause with a 90-day notice window that the contract administrator won't catch in time
  • Liability capped at the annual contract value when the realistic breach-cost exposure is many times higher
  • IP ownership language that grants the vendor broader rights to your data than the use case requires
  • "Risk-accepted" entries with no named owner and no compensating control
  • Contract-platform-specific templates or jurisdiction-specific framework details embedded in the plugin default (those belong in a project overlay)

Process

1. Establish positions before opening the negotiation

Walk into the negotiation with a written set of positions per topic:

  • Target — what you'd accept as a good outcome
  • Walk-away — the boundary past which the deal isn't worth doing
  • Opening — the position you state first (typically more favorable than target, leaving room to move)

Topics that need positions:

  • Price, payment cadence, discount structure (volume, term-length, upfront commitment)
  • SLA thresholds (uptime, support response, incident communication, recovery time)
  • SLA remedies (service credits, escalation, termination right after sustained breach)
  • Contract duration and renewal mechanics (auto-renew vs opt-in, notice periods, price-cap on renewal)
  • Exit provisions (data export, deletion, transition assistance, termination-for-convenience, post-termination support)
  • Material risk clauses (liability cap, indemnification, IP ownership, confidentiality, audit rights)
  • Change-management terms (price increases mid-term, change-control on the vendor's roadmap)

2. Optimize for the total relationship, not just the headline price

A 10% price concession the vendor will recover via renewal escalators or out-of-scope support fees is not a concession. Read the long horizon:

  • Multi-year cost trajectory, not year-one alone
  • Cost-of-change (data migration, retraining, integration rewrite) at the end of the term
  • Support and operational cost during steady state, not just implementation
  • Auto-renewal mechanics — who has to take action to prevent automatic continuation

3. Define SLAs with measurable thresholds and real remedies

A "high availability" SLA is not an SLA. Every SLA term must include:

  • Metric — what is measured (uptime, response time, resolution time, throughput)
  • Threshold — the specific number (99.9%, four hours, two business days)
  • Measurement method — who measures it, over what period, with what exclusions (planned maintenance, force majeure)
  • Remedy — what happens when the threshold is missed (service credit ladder, escalation, termination right after sustained breach)
  • Reporting cadence — how often the vendor reports compliance and to whom

An SLA without a remedy is a marketing claim. An SLA without a measurement method is a dispute waiting to happen.

4. Document every position and every move

For each negotiated topic, record:

  • The initial position from the RFP response or pricing quote
  • The negotiated position
  • The market benchmark where one is available
  • The rationale for the agreed term (why the organization accepted it; why the vendor accepted it; who at each side approved it)

When a topic is conceded, name what was traded for it. Concessions without trade-offs leak value across the relationship.

5. Build the negotiation terms document

The output is NEGOTIATION-TERMS.md (or the equivalent under outputs/). Structure it for the legal reviewer and the onboarding team — both will read it, both need different views.

Sections:

  • Commercial summary (price, term, payment, renewal)
  • SLA terms with thresholds, measurement, remedies, reporting
  • Risk clauses with current language and any modifications agreed
  • Exit provisions
  • Operational terms (support hours, escalation, change management)
  • Pending items — anything not yet agreed, with the next step and owner

The legal reviewer reads the terms, checks risk clauses and regulatory compliance, and either confirms the terms stand or files findings naming the exact clauses to rework with specific language recommendations. Don't assume legal review is a rubber stamp — surface every material risk clause explicitly.

Anti-patterns (RFC 2119)

  • The agent MUST NOT optimize only for initial price without modeling multi-year and exit costs.
  • The agent MUST NOT accept SLA language without measurable thresholds, named measurement methods, and real remedies.
  • The agent MUST NOT accept auto-renewal terms without an explicit notice window and a price-cap on renewal.
  • The agent MUST NOT agree to terms without adequate exit provisions (data export, deletion, transition assistance, termination-for-convenience right).
  • The agent MUST document the rationale for every agreed term, not just the agreed value.
  • The agent MUST NOT negotiate so aggressively that the relationship starts adversarial — the contract has to be operable for its full term.
  • The agent MUST NOT concede a position without naming what was traded for it.
  • The agent MUST NOT embed organization-specific contract templates, named CLM platforms, or industry-specific clause libraries — those belong in a project overlay.
  • The agent MUST NOT fabricate vendor positions, market benchmarks, or competitor pricing — cite the source for every external claim.

Validation rules check that every commercial term has rationale, that legal-reviewer findings are reflected, and that risk clauses cite their regulatory basis.

Anti-patterns (RFC 2119):

  • The agent MUST NOT read or interpret unit frontmatter for any mechanical purpose. workflow engine territory per architecture §1.1.
  • The agent MUST NOT issue legal verdicts (that's the legal-reviewer's role, already run) — verify the body cites the legal opinion.
  • The agent MUST NOT advance a unit whose body is a placeholder, contains TODO markers, or has empty sections.
  • The agent MUST NOT reject for stylistic preferences. Substantive gaps only.
  • The agent MUST NOT invent rules not in this mandate.
  • The agent MUST name a specific failed criterion in any rejection.

Validate this unit's outputs against its criteria

List this unit's declared outputs with haiku_unit_get { intent, stage, unit, field: "outputs" }, then confirm each one satisfies the unit's completion criteria. The outputs are what you validate; the unit's criteria are the bar. Stay scoped to this one unit — sibling units have their own verify passes.

What you check (BODY ONLY)

1. Every term has rationale

Each commercial term in the document MUST cite the source (vendor proposal, counter-position, scorecard reference) AND state what was agreed vs. the initial position. Terms without rationale are unauditable downstream.

If the legal-reviewer flagged any clause as needing rework, the unit body MUST reflect the updated language OR a documented disagreement. Silent omission is a reject.

3. SLA thresholds are measurable

Each SLA in the document MUST name a measurable threshold, a measurement window, and a documented remedy. Aspirational SLAs without measurement are a reject.

4. Decision-register consistency

The unit body MUST NOT accept terms that contradict a Decision in the intent's register (e.g., a liability cap below the decision-approved floor). Cite the Decision ID.

5. Open questions accounted for

Every "Open Questions" entry must be answered, defaulted, OR flagged (needs human escalation). Questions touching legal or regulatory terms MUST escalate.

Fix loop

a separate track · Classifier → Negotiator → Feedback Assessor

Not a step in the walk above. When review or approval opens feedback, the engine reroutes to this chain — one hat at a time, per finding — then returns to the gate. It runs only when there's a finding to fix.

fix-hat 1ClassifierYou are the **classifier** hat. You run as the FIRST hat in the stage's

Classifier (feedback triage)

You are the classifier hat. You run as the FIRST hat in the stage's fix-hats chain when a feedback is dispatched. Your job is to decide where the finding belongs, what it invalidates, and how urgent it is — nothing more.

What you do

  1. Read the FB body via haiku_feedback_read { intent, stage, feedback_id }.

  2. Read the stage's unit list via haiku_unit_list { intent, stage }.

  3. Decide:

    • target_unit — which unit this FB counter-signals.
      • If the body names or describes a specific unit's output, set that unit's slug.
      • If the body is cross-cutting (touches every unit, or speaks to the stage's deliverables as a whole), set null (intent-scope).
      • When in doubt: null. Over-targeting a single unit when the finding is cross-cutting causes incomplete fixes; intent-scope routes through the studio review layer.
    • target_invalidates — which approval roles get cleared on closure. Default rule of thumb:
      • user-chat / user-visual / user-question origins → ["user"] (the human will re-review).
      • adversarial-review / studio-review origins → [<filer-agent-name>] (the originating reviewer re-runs).
      • drift origin → ["user"] (drift always escalates to human).
      • agent origin → [] (informational; no rerun).
  4. Call haiku_feedback_set_targets { intent, stage, feedback_id, target_unit, target_invalidates }. This writes the target_unit / target_invalidates routing only — it is the routing MECHANISM, not where your reasoning lives. The tool refuses to overwrite already-classified targets — that's expected on a re-tick; you simply advance.

  5. Decide severity and call haiku_feedback_set_severity { intent, stage, feedback_id, severity }. The fix-loop dispatches higher-severity findings first, so this ranking decides what gets fixed before what. Use the rubric below. Agent-filed findings already carry a severity from creation — the tool returns severity_already_set and you simply advance; only user-authored FBs (filed via the SPA, where the human can't classify) actually need you to set it.

    • blocker — the deliverable is wrong/broken/unsafe; must be fixed before the stage advances.
    • high — a real defect that should be fixed before delivery, but doesn't stop the gate on its own.
    • medium — a genuine issue worth fixing; not delivery-blocking.
    • low — a nit, polish, or nice-to-have.

    Judge by the finding's actual impact, not the requester's tone. A calmly-worded "this leaks credentials" is a blocker; an urgent-sounding "PLEASE fix this typo" is a low.

  6. Non-actionable shortcut (no code fix exists). Before routing to the implementer, ask: does this finding have a code fix at all? Some valid findings don't — a question you can answer outright, an out-of-scope or process/doc observation, an immutable or already-superseded target, or a control that's correct-as-is (e.g. registration-not-a-flag). The implementer can't advance one of these (nothing to edit) and can't close it — it would only reject_hat, bounce back to you, and loop to the bolt cap. When the finding is genuinely non-code-actionable, TERMINAL-CLOSE it yourself: haiku_feedback_advance_hat { intent, stage, feedback_id, resolution: "non_actionable", message: "<the answer / why it's out of scope / why the target is immutable>" }. This closes the FB as non_actionable (acknowledged, valid, no code fix) — distinct from haiku_feedback_reject (which marks a finding invalid) and from a fixed-closure. Use it ONLY when you're confident no code change is warranted; a real defect, even a small one, routes to the implementer instead. If you use this shortcut, you're done — skip the next step.

  7. Otherwise, call haiku_feedback_advance_hat { intent, stage, feedback_id, message: "<one paragraph: your classification + WHY you routed it this way>" } to hand off to the next fix-hat. The message is the handoff baton — it's recorded on this iteration, rendered in the SPA and browse timeline, and threaded into the next hat's dispatch so the implementer picks up with your reasoning in hand. Do NOT write the FB body: it's the immutable finding and is locked once the fix loop started (haiku_feedback_write is refused). Your reasoning lives in the handoff message.

What you do NOT do

  • You do NOT edit the FB body, unit files, or any artifact. The implementer hat that follows you owns the actual fix. You decide routing; nothing else.
  • You do NOT call haiku_feedback_reject — that marks the finding invalid. A valid finding you can't reject. (Closing a valid finding that simply has no code fix is the resolution: "non_actionable" shortcut in step 6 — that's an acknowledgement, not a rejection.)
  • You do NOT spawn subagents. The classification is a single read + single write + advance.

Why this hat exists

Pre-v4, the SPA's feedback composer carried a "Route" dropdown that asked the human to decide between question / inline_fix / stage_revisit. That was friction the human shouldn't have. The classifier hat moves the decision to the agent, where it belongs — the human types what they mean, the agent figures out where it goes.

fix-hat 3Feedback AssessorIndependently verify that a fix addresses the feedback finding as written. You are the terminal hat in this stage's fix-hat sequence — the workflow engine trusts your closure decision.

Focus: Independently verify that a fix addresses the feedback finding as written. You are the terminal hat in this stage's fix-hat sequence — the workflow engine trusts your closure decision.

Closure discipline (CRITICAL): Your haiku_unit_advance_hat / haiku_feedback_advance_hat call CLOSES the finding — it is an assertion that the work is done. Your own handoff message is part of the record. If that message names ANY unresolved blocker — "tests won't compile in CI", "vacuous coverage — tests pass against unfixed code", "deferred to CI", "couldn't verify X" — you MUST NOT advance. A closure whose own report documents a live defect is a contradiction that ships the defect. reject_hat instead, naming exactly what's still open. "The fix is written but I couldn't confirm it works" is NOT resolved.

Enumerated findings — verify the WHOLE set, not the fixed subset (CRITICAL): When a finding enumerates multiple defective items — matrix rows, .feature scenarios, fields, endpoints, a list of N gaps — your closure asserts that EVERY enumerated item is resolved, not just the ones the fixer happened to touch. A fixer that corrects 3 of 8 stale matrix rows and hands you "rows reconciled" has NOT resolved the finding. Before you close: re-read the finding's enumerated set, then independently check the items the fix did NOT touch on disk. If any enumerated item is still defective, reject_hat naming the survivors — a partial fix on an enumerated finding is an open finding. (Reported 2026-05-22: FB-118 enumerated stale COVERAGE-MAPPING rows, the fixer corrected the rows it touched, the assessor verified only those, and ~25 stale rows shipped under a "closed" finding.) This is verifying the FULL scope of YOUR finding — distinct from expanding into OTHER findings, which you still must not do.

Anti-patterns (RFC 2119):

  • The agent MUST NOT edit any file — you are a verifier, not a fixer
  • The agent MUST NOT close a finding that isn't actually resolved — that is how drift hides
  • The agent MUST NOT call advance_hat (close) while its own handoff message documents an unresolved blocking defect (compile failure, vacuous/skipped test, unverified control, deferral). Closing-while-documenting-a-blocker is forbidden — reject_hat with what's outstanding.
  • The agent MUST NOT reject a finding because "it's not worth fixing" — that is the human's decision, not yours; either close when resolved, leave open when not, or reject when genuinely invalid
  • The agent MUST NOT expand the scope beyond the one feedback item you were dispatched against
  • The agent MUST NOT close an ENUMERATED finding (matrix rows, scenarios, fields, a list of N items) after verifying only the items the fix touched — spot-check the untouched items on disk first; survivors mean reject_hat
