| description | Distill Opus-level reasoning into optimized instructions for Haiku 4.5 (and Sonnet). Generates explicit, procedural prompts with n-shot examples that maximize smaller model performance on a given task. Use when user says "down-skill", "distill for Haiku", "optimize for Haiku", "make this work on Haiku", "generate Haiku instructions", or needs to delegate a task to a smaller model with high reliability. |

Down-Skilling: Opus → Haiku Distillation
Translate your reasoning capabilities into explicit, structured instructions
that Haiku 4.5 can execute reliably. You are a compiler: your input is
context, intent, and domain knowledge; your output is a Haiku-ready prompt
with decision procedures and diverse examples.
Core Principle
Opus infers from WHY. Haiku executes from WHAT and HOW.
Your job: convert implicit reasoning, contextual judgment, and domain
expertise into explicit procedures, concrete decision trees, and
demonstrative examples. Every inference you would make silently, Haiku
needs stated explicitly.
Economics: Why Examples Are Free
Opus input costs ~6× Haiku input. A task that costs $1.00 on Opus costs
~$0.17 on Haiku — but only if Haiku gets it right on the first try.
One retry wipes the savings; two retries makes Haiku more expensive.
The math that matters:
- Input tokens are cheap (Haiku: $0.80/MTok input vs $4.00/MTok output)
- Adding 2,000 tokens of examples costs ~$0.0016 per call
- A single failed-then-retried call costs ~$0.008+ in wasted output
- Examples pay for themselves if they prevent even 1-in-5 retries
What this means for prompt design:
- If you're sending an 8K token document, you can afford 3-4K tokens of
examples — the examples cost less than the document itself
- Lengthy input prompts don't inflate output costs — output pricing is
independent of input length
- The constraint is not token cost but diminishing returns: after 5-7
examples, additional examples rarely improve performance
Bottom line: Every example that prevents a Haiku misfire saves 5-25×
its input cost in wasted output tokens. Under-investing in examples is
the most expensive mistake in down-skilling.
Activation
When triggered, perform these steps:
-
Extract task context from the conversation: what is the user trying
to accomplish? What domain knowledge applies? What quality criteria
matter?
-
Identify the reasoning gaps — what would Opus infer automatically
that Haiku needs spelled out? Common gaps:
- Ambiguity resolution (Opus picks the sensible interpretation; Haiku
needs a decision rule)
- Quality judgment (Opus knows "good enough"; Haiku needs explicit
criteria)
- Edge case handling (Opus reasons through novel situations; Haiku
needs enumerated cases)
- Output calibration (Opus matches tone/length intuitively; Haiku
needs explicit constraints)
-
Generate the distilled prompt following the structure in
Prompt Architecture
-
Generate 4-7 diverse examples following the principles in
Example Design — this is the highest-leverage step
-
Deliver the complete Haiku-ready prompt as a copyable artifact or
file, including system prompt and user prompt components as appropriate
Prompt Architecture
Structure every distilled prompt with these components in this order.
Haiku responds best to this specific sequencing:
<role>
[Single sentence: who Haiku is and what it does]
</role>
<task>
[2-3 sentences: the specific task, its purpose, and the deliverable]
</task>
<rules>
[Numbered list of explicit constraints. Be precise about:]
- Output format (JSON schema, markdown structure, etc.)
- Length bounds (word/token counts, not vague "brief"/"detailed")
- Required elements (must-include fields or sections)
- Prohibited behaviors (specific failure modes to avoid)
- Decision rules for ambiguous cases
</rules>
<process>
[Numbered steps. Maximum 7 steps. Each step is one action.]
[Include validation checkpoints: "Before proceeding, verify X"]
[Include decision points: "If X, do Y. If Z, do W."]
</process>
<examples>
[4-7 diverse examples showing input → output pairs]
[This section should be the LARGEST part of the prompt]
[See Example Design section for distribution requirements]
</examples>
<context>
[Task-specific data, reference material, or domain knowledge]
[Use labels: [Context], [Policy], [Reference]]
</context>
Haiku Optimization Rules
Apply these when generating any Haiku-targeted prompt:
Structure & Syntax
- Use XML tags to delimit every section — Haiku respects labeled boundaries
- Keep sentences under 25 words where possible
- One instruction per sentence; split compound instructions
- Use numbered steps, not prose paragraphs, for procedures
- Specify token/word budgets explicitly: "respond in 80-120 words"
Reasoning Support
- Replace open-ended judgment with decision rubrics:
BAD: "Assess whether the code is production-ready"
GOOD: "Check: (a) no TODO comments, (b) all functions have error
handling, (c) no hardcoded secrets. Score pass/fail per item."
- Bound reasoning depth: "Think in 3-5 steps, then give your answer"
- Provide a fallback for uncertainty: "If you cannot determine X,
respond with: 'UNCERTAIN: [brief reason]'"
Context Management
- Front-load critical instructions (Haiku attends strongly to position)
- Budget rule of thumb: instructions + rules ≤ 800 tokens, examples get
the rest. For a task processing an 8K document, 3-4K tokens of examples
is well within budget and pays for itself in reliability
- Pass only the 1-3 most relevant context snippets, not full documents
- Use explicit delimiters between context and instructions
Output Control
- Require structured output (JSON, labeled sections) for extractable results
- Provide an output template Haiku can fill in
- Specify what comes first in the response: "Begin your response with..."
- For classification tasks, enumerate all valid categories
Failure Prevention
- Anticipate Haiku's common failure modes and add guardrails:
- Hallucination: "Use ONLY information from the provided context.
If the answer is not in the context, say 'Not found in sources.'"
- Verbosity: "Maximum 150 words. Do not add preamble or caveats."
- Format drift: Include the output schema in both rules and examples
- Instruction skipping: Number all constraints; reference them in
the process steps: "Apply rules 2-4 from "
Example Design
Examples are the single highest-leverage investment in a Haiku prompt.
Rules tell Haiku what to do; examples show it what "done right" looks
like. When rules and examples conflict, Haiku follows the examples.
When rules are ambiguous, Haiku extrapolates from examples. This makes
examples the primary steering mechanism — not a supplement to rules, but
the dominant signal.
Given the economics (see Economics),
you should invest heavily here. A prompt with 800 tokens of rules and
3,000 tokens of examples will outperform one with 2,000 tokens of rules
and 500 tokens of examples almost every time.
Minimum Example Count: 4
Generate 4-7 diverse examples per distilled prompt. Fewer than 4 is
under-investing. The marginal cost of each example is negligible compared
to the reliability improvement. Use this distribution:
| # | Role | Purpose |
|---|
| 1 | Typical case | The most common, straightforward input. Establishes the baseline pattern. |
| 2 | Second typical variant | A different but common input — varies length, domain, or structure from #1. Prevents Haiku from over-fitting to a single pattern. |
| 3 | Edge case | Unusual but valid input: empty fields, very long text, special characters, boundary conditions, ambiguous phrasing. |
| 4 | Negative/rejection case | Input that should be rejected, handled differently, or produce an empty/default output. Shows Haiku what NOT to do. |
| 5+ | Tricky/boundary cases | Inputs near decision boundaries where Haiku is most likely to fail. The cases you'd use for a test suite. |
Why the second typical case matters: With only one typical example,
Haiku may latch onto incidental features of that example (its length,
word choice, domain). A second typical case from a different angle shows
Haiku which features are task-relevant and which are coincidental.
Example Format
<example>
<input>
[Realistic input data — use real-world length and complexity]
</input>
<output>
[Exact format Haiku should produce — not a description, the actual output]
</output>
<reasoning>
[1-2 sentences: WHY this output is correct. Which rules applied.
What Haiku might have gotten wrong without this example.]
</reasoning>
</example>
The <reasoning> tag is not optional for complex tasks. It acts as
a chain-of-thought anchor, showing Haiku the reasoning pattern to follow.
For classification and extraction tasks, reasoning should reference the
specific rule numbers that drive the decision.
Example Sizing Guidance
| Task processing... | Recommended example budget |
|---|
| Short inputs (<500 tokens) | 1,500-2,500 tokens of examples (4-5 examples) |
| Medium inputs (500-4K tokens) | 2,500-4,000 tokens of examples (4-6 examples) |
| Long inputs (4K-8K tokens) | 3,000-5,000 tokens of examples (5-7 examples) |
These budgets assume Haiku's 200K context window. The constraint is
diminishing returns, not cost — after 7 examples the marginal benefit
drops sharply unless the task has a very large classification space.
Example Quality Criteria
- Examples must be realistic, not toy data — match the complexity and
messiness of real inputs
- Output format must be identical across all examples — Haiku treats
format inconsistency as a signal that format doesn't matter
- Include the hardest case you expect Haiku to handle
- Vary input characteristics: length, complexity, domain, tone
- Never include an example that contradicts your rules
- Order examples from simplest to most complex — this progressive
difficulty helps Haiku build up its understanding
Delivery Format
Present the distilled prompt in a code block or artifact with clear
section markers. Include:
- System prompt (if applicable): role + persistent rules
- User prompt template: with {{placeholders}} for variable content
- Examples: embedded in the prompt or as a separate few-shot section
- Usage notes: any caveats about when this prompt may fail and what
to watch for
When generating for API use, include the model parameter and recommended
settings:
model: claude-haiku-4-5-20251001
max_tokens: [appropriate for task]
temperature: 0 (for deterministic tasks) or 0.3 (for creative tasks)
