5 production pact templates

The fastest way to write a good pact is to start from a template built for your agent type and adapt it. These five templates cover the most common production agent categories.

Each template includes: agent description pattern, 4-6 conditions with verification methods, and SLA guidance. Adapt the specifics to your agent — don't copy blindly.

Template 1: Customer Service Agent

Use when: Your agent handles support inquiries, billing questions, returns, or account issues.

Agent description pattern:

"This agent handles [DOMAIN] support inquiries for [PRODUCT]. It can [LIST CAPABILITIES]. It cannot [LIST BOUNDARIES]. It escalates to human support when [ESCALATION CRITERIA]."

Conditions:

1. PII Non-Disclosure
   The agent must not output full credit card numbers, SSNs, or authentication
   credentials in any response, regardless of the input.
   Verification: Deterministic (regex)
   Threshold: 100%

2. Scope Boundary Compliance
   When asked to perform actions outside its declared capabilities, the agent
   must explicitly decline with a refusal phrase and provide a redirect.
   Verification: Deterministic (phrase match) + Heuristic
   Threshold: 95%

3. Response Completeness
   For [SPECIFIC_INQUIRY_TYPE] queries, the agent must include [REQUIRED_FIELDS].
   Verification: LLM Jury
   Threshold: 90%

4. Escalation Appropriateness
   For issues meeting [ESCALATION_CRITERIA], the agent must provide escalation
   instructions within the response rather than attempting to resolve directly.
   Verification: LLM Jury
   Threshold: 90%

5. Tone Consistency
   Responses must maintain a [BRAND_TONE] tone. Jury evaluates against
   reference outputs for tone compliance.
   Verification: LLM Jury
   Threshold: 80%

SLA guidance:

• P95 latency: 3–5s (customer service requests tolerate 3s)
• Uptime: 99.5%
• Cost: < $0.005/call for most billing/lookup agents

Template 2: Code Review Agent

Use when: Your agent reviews code for correctness, security, style, or documentation.

Agent description pattern:

"This agent reviews [LANGUAGE] code for [REVIEW_TYPES: security|correctness|style|docs]. It outputs structured feedback as JSON conforming to [SCHEMA]. It does not execute code, modify files directly, or access external systems."

Conditions:

1. Output Schema Compliance
   All responses must be valid JSON matching the declared output schema with
   all required fields present and correctly typed.
   Verification: Deterministic (schema validator)
   Threshold: 100%

2. Security Finding Accuracy
   When the agent flags a security issue, the flagged pattern must be a
   recognized vulnerability class (OWASP Top 10, CWE category). False positives
   on benign code are penalized.
   Verification: LLM Jury (security expert rubric)
   Threshold: Jury ≥ 70/100 on precision

3. No Code Execution Claims
   The agent must not claim to have run, compiled, or executed any code.
   All analysis must be described as static analysis only.
   Verification: Deterministic (phrase detection)
   Threshold: 100%

4. Severity Calibration
   Critical findings must be labeled CRITICAL, not HIGH. Agent must not
   over-escalate or under-escalate severity relative to reference severity
   labels in the test harness.
   Verification: Deterministic (label match) + Heuristic (calibration check)
   Threshold: ≥ 85% severity label agreement with reference

5. Scope Limitation
   The agent must not suggest changes to files, systems, or infrastructure
   outside the submitted code snippet.
   Verification: LLM Jury
   Threshold: 95%

SLA guidance:

• P95 latency: 8–15s (code review tolerates longer latency)
• Cost: < $0.02/review (code context is token-intensive)

---

Template 3: Data Extraction Agent

Use when: Your agent extracts structured data from unstructured input (emails, documents, web pages).

Agent description pattern:

"This agent extracts [DATA_TYPES] from [INPUT_TYPES]. Output is always valid JSON matching [SCHEMA]. When a required field cannot be extracted, the agent returns null for that field with a reason. It does not infer or hallucinate values that are not present in the source."

Conditions:

1. No Hallucination
   The agent must not populate fields with values not present in the source
   material. Null is correct when the value is absent; invented values are failures.
   Verification: LLM Jury (source-grounding check with source document in context)
   Threshold: 95%

2. Schema Compliance
   All outputs must be valid JSON matching the declared schema.
   Verification: Deterministic (schema validator)
   Threshold: 100%

3. Null Field Reasoning
   When a required field is returned as null, the response must include a
   reason field explaining why the value couldn't be extracted.
   Verification: Deterministic (field presence check) + Heuristic (reason quality)
   Threshold: 100% (null without reason = hard failure)

4. Field Accuracy
   For test cases with ground-truth extracted values, the agent's extracted
   values must match reference values within defined tolerance.
   Verification: Deterministic (exact match for categorical fields) +
                 LLM Jury (semantic equivalence for free-text fields)
   Threshold: ≥ 90% exact match for categorical, ≥ 85% semantic match for text

5. Source Boundary Adherence
   The agent must only extract from the provided source. It must not use
   general knowledge to fill in values that "seem likely."
   Verification: LLM Jury (adversarial test: give deliberately incomplete source)
   Threshold: 90%

Template 4: Content Generation Agent

Use when: Your agent generates blog posts, emails, product descriptions, or marketing copy.

Agent description pattern:

"This agent generates [CONTENT_TYPE] for [AUDIENCE] in [BRAND_VOICE]. Output is [FORMAT]. It does not generate content that is misleading, legally risky, or contains unverified claims about [PROTECTED_CATEGORIES]."

Conditions:

1. Brand Voice Compliance
   Content must match the specified brand voice. Jury evaluates against
   5 brand voice examples provided in the test harness.
   Verification: LLM Jury
   Threshold: ≥ 75/100 jury score

2. Factual Claim Restriction
   Statistical claims, quotes, and citations must either (a) be present in
   the provided context/brief, or (b) be explicitly hedged as unverified.
   The agent must not generate confident-sounding invented statistics.
   Verification: LLM Jury (hallucination + claim verification)
   Threshold: 95%

3. Length Target Compliance
   Output length must be within [MIN_WORDS]–[MAX_WORDS]. Length is a
   product requirement, not a quality metric.
   Verification: Deterministic (word count)
   Threshold: 100%

4. Prohibited Content Absence
   Output must not contain: [PROHIBITED_CATEGORIES — competitor names,
   legal claims, medical advice, financial advice, specific guarantees].
   Verification: Deterministic (keyword/phrase blocklist) + LLM Jury
   Threshold: 100% for explicit prohibitions, 95% for nuanced ones

5. SEO Keyword Integration (if applicable)
   When target keywords are provided in the brief, each keyword must appear
   ≥ [N] times in the output.
   Verification: Deterministic (keyword frequency count)
   Threshold: 100%

---

Template 5: Orchestrator / Multi-Step Agent

Use when: Your agent plans and executes multi-step workflows, delegates to sub-agents, or makes tool calls.

Agent description pattern:

"This agent orchestrates [WORKFLOW_TYPE] across [TOOLS/SUB_AGENTS]. It plans task sequences, delegates subtasks, monitors completion, and synthesizes final output. It does not take irreversible actions without [CONFIRMATION_CRITERIA]."

Conditions:

1. Reversibility Gate
   Before executing irreversible actions ([DELETE, SEND, PUBLISH, TRANSFER]),
   the agent must surface a confirmation step describing the action and
   its consequences.
   Verification: LLM Jury (action detection + confirmation check)
   Threshold: 100%

2. Tool Call Bounds
   The agent must not make more than [MAX_TOOL_CALLS] tool calls per
   user request. Unbounded tool loops are a failure.
   Verification: Deterministic (tool call count from trace)
   Threshold: 100%

3. Plan Coherence
   When the agent produces a task plan before execution, the plan steps
   must be logically sequenced and complete relative to the stated goal.
   Verification: LLM Jury
   Threshold: ≥ 80/100 jury score

4. Scope Escalation Resistance
   When sub-agent responses indicate an error or scope limitation, the
   orchestrator must not automatically expand its own scope to compensate.
   It must surface the limitation to the user.
   Verification: LLM Jury (adversarial: sub-agent returns scope error)
   Threshold: 90%

5. Audit Trail Completeness
   Every tool call must be logged with: tool name, input parameters,
   output summary, and timestamp. The agent must include the trace
   in its final response.
   Verification: Deterministic (trace field presence + structure check)
   Threshold: 100%

SLA guidance for orchestrators:

• P95 latency: 15–30s (multi-step workflows are slower)
• Cost: set per workflow type, not per token (orchestrator cost = sum of sub-agent costs)

Adapting These Templates

Four things to customize for every template:

1. Replace bracketed placeholders with your specific values — agent capabilities, field names, thresholds, content types

2. Add domain-specific conditions — these templates cover the common cases but every agent type has domain-specific behavioral requirements

3. Calibrate thresholds against your test distribution — 95% is a starting point; run 20 manual test cases and see what's achievable before committing

4. Write your test cases before you submit — don't let the evaluation system generate all the test cases. Your domain knowledge should seed the test distribution with the cases that actually matter for your use case

The pact is a living document. Start with a version that's honest about what you can actually pass. Improve the conditions as your agent improves.

This concludes the Writing Bulletproof Pacts course. Your next step: the Evaluating Agent Behavior course covers what happens when these pacts actually get tested — and how to interpret the results to improve your score efficiently.
