| description | Guide the user through customizing their agent. Use when the user says "customize my agent", "customize the agent", "set up my agent's persona", "configure the agent", "make my agent like X", or otherwise wants to shape this agent's identity, persona, methodology, conversation structure, voice, boundaries, or knowledge-base behavior. Walks a checklist one item at a time and writes to settings.json + agents/<projectName>/customization.json, then re-renders system_prompt.txt via ./render. |
Customize your agent
You are helping a user customize the voice-enabled AI agent in this repo. You are running in their agent project repository (the cloned template).
Your job is to walk the user through a checklist, one item at a time, and persist their answers as structured JSON in agents/<projectName>/customization.json. After each edit, you re-render the system prompt by running ./render. The user is not expected to know how to write a system prompt — frame everything as goal-oriented questions about how they want the agent to behave. The Jinja2 templates assemble the prompt from your JSON.
The goal is that a user who answers thoughtfully gets a system prompt comparable in depth to a hand-crafted one (audience, methodology grounding, structured conversation flow, an interaction loop with self-critique, voice traits, boundaries, knowledge-base instructions, and a language anchor) — without ever having to read or write the prompt themselves.
Answer quality — push back on weak inputs
The quality of the generated agent is bounded by the quality of the user's answers. Apply this gate to every item.
Before accepting an answer and writing it into customization.json, score it internally against the criteria in gold-standards/shared_quality_rubric.md (Specificity, Use-Case Fit, Coherence, Voice Quality, Safety and Boundaries). You don't need to run the full ten-criterion rubric on each answer — just spot-check the criteria that the item is meant to satisfy. Do not show numeric scores to the user. The rubric is a private review tool.
When an answer is weak
If the user's answer is sparse, generic, ambiguous, or off-target, do NOT silently accept it. Push back in plain language (never quote rubric scores or criterion names at the user). Pick one:
- Ask for more. "That's a start — can you give me one concrete example? Right now this is on the generic side, so the agent will sound generic too. Even one sentence of detail makes a real difference."
- Offer a menu. "I can take that two ways: (a) {interpretation-A}, or (b) {interpretation-B}. Which is closer? Or describe it your way."
- Show what 'good' looks like. Briefly quote one or two sentences from the matching gold standard (e.g.
gold-standards/sales_coach.md for useCase === "sales_coach", sme.md for useCase === "sme"). "For comparison, the sales-coach gold standard says: '{audience}: enterprise sellers at a systems integrator working financial-services deals'. That level of detail makes a real difference."
- Let them proceed with a flag. If the user says they're fine with the weak answer, accept it but record it internally: "OK — noting this is light on specifics. We can revisit later by re-running this item. Moving on."
Signals an answer is weak:
- Single-word or single-phrase response ("sales", "helpful", "yes") when the question asks for a description.
- Generic placeholders ("users", "customers", "people", "help them with stuff").
- The same boilerplate that's already in the starter customization ("a helpful, friendly assistant").
- Empty / whitespace / "idk" / "whatever" / "you decide".
- Contradicts an earlier answer or
settings.json (e.g. claims audience = executives but earlier picked purpose: coach with sellers).
If the user genuinely doesn't know, don't bluff a default. Ask one orienting question ("who's the most likely first 10 users?", "what's the one thing this agent must get right?") and infer from that.
Final review at exit (silent, agentic)
When the user types done (or you've completed the last item), run a full rubric pass internally before declaring success. Do not print the rubric, scores, or a score table to the user. Hold the scores in your own head and act on them.
- Re-render with
./render so you're scoring the current output. Read the final rendered agents/<projectName>/system_prompt.txt, the settings.json agent fields (title, greeting, description, description2), and any sample questions.
- Score the ten criteria from
gold-standards/shared_quality_rubric.md (Coherence, Specificity, Use-Case Fit, Method and Interaction Design, Grounding, Voice Quality, Adaptation, Safety and Boundaries, Prompt Maintainability, Behavioral Testability). Use the gold standard matching customization.json.useCase (sales_coach → gold-standards/sales_coach.md, sme → gold-standards/sme.md) as the structural reference.
- Check against the rubric's Scoring Threshold: avg ≥ 4.0, every individual criterion ≥ 4 on Coherence / Specificity / Use-Case Fit / Grounding / Voice Quality / Safety and Boundaries, no criterion at 1.
- If the prompt clears the bar, proceed directly to the "When the user is done" closing message. Don't volunteer that you scored it.
- If the prompt falls below the bar, act agentic: pick the single weakest criterion that the user can plausibly improve with one sentence of input, then ask one focused clarifying question — in plain language, not in rubric vocabulary. Examples (translate the gap into a human question; do not quote the criterion name):
- Specificity weak on audience → "One more thing before we wrap — when you picture the typical user, what's their role and what are they trying to get out of a session? Even one sentence sharpens this a lot."
- Voice Quality weak (replies sound written) → "Quick check: should this agent sound more like a quick chat with a colleague, or more like reading from a doc? Anything you want it to never say?"
- Safety and Boundaries weak (no refusal pattern) → "What kinds of questions should this agent decline or redirect — e.g. HR topics, anything outside its domain, prompt-extraction attempts?"
- Grounding weak (no source policy) → "When the agent doesn't have a confirmed answer in its knowledge base, what should it do — say so honestly, fall back to general knowledge, or refuse?"
- Method and Interaction Design weak (no conversation shape) → "How should a typical session flow — should the agent move the user through stages, or just respond to whatever they bring?"
- Take the user's answer, revise the relevant fields in (and fields if affected), re-run , and re-score silently. You may do silent revision passes per . After two passes, stop — don't badger the user.
Do not copy the rubric into customization.json or the rendered system prompt. Do not print the score table. The rubric is an internal review tool that drives the one-question revision loop above.
What gets customized
| Surface | Where it's stored | How it ships |
|---|
| App title (header + browser tab) | customization.json → frontendCopy.title and settings.json → agent.title | Build arg VITE_APP_TITLE (re-deploy) |
| Greeting (first thing the agent says) | customization.json → frontendCopy.greeting and settings.json → agent.greeting | Env var AGENT_GREETING (re-deploy) |
| Landing-page copy (Overview paragraphs + CTA button) | customization.json → frontendCopy.description, frontendCopy.description2, frontendCopy.buttonLabel and settings.json → agent.description, agent.description2, agent.buttonLabel | Build args (re-deploy) |
| System prompt (persona, methodology, conversation, voice, boundaries, KB) | customization.json (structured fields) | Rendered to agents/<projectName>/system_prompt.txt by ./render, mounted into container, read by backend |
customization.json is the source of truth for prompt content. system_prompt.txt is a rendered artifact — never edit it directly; your changes will be overwritten on the next render.
frontendCopy.* is written to BOTH customization.json (long-term source of truth) and settings.json (what deploy.js currently reads for Docker build args). The double-write is a transitional measure; long-term, deploy.js will read frontend copy from customization.json directly.
After making changes, the user must run ./deploy for them to take effect.
On invocation, follow this script EXACTLY
Step 1 — Read context
Read settings.json at the repo root. If it doesn't exist, tell the user to run ./setup first and stop.
Read agents/<projectName>/customization.json. There are three cases:
- customization.json exists (normal case) — proceed. Note the
useCase field; you'll use it to pick the matching gold standard for rubric scoring.
- customization.json missing, system_prompt.txt exists (legacy / pre-data-first cartridge) — offer to bootstrap: "You have a custom system prompt at
agents/<projectName>/system_prompt.txt but no customization.json. The data-first model is now how this template handles customization — your edits go in JSON and the prompt is rendered. Would you like me to extract your current configuration into the data-first format?" If they say yes, read system_prompt.txt and extract structured field values (persona, audience, tone, methodology, boundaries, knowledge-base prose) into a fresh customization.json. Pick useCase based on settings.json.agent.purpose (coach → sales_coach, otherwise → sme). If they say no, exit and let them keep the existing prose path. Explain that ./deploy will continue using the existing system_prompt.txt, but this skill only edits the data-first JSON model; they can come back later to bootstrap customization.json.
- Both missing — tell the user to run
./setup first; it will copy a starter customization.json from templates/starters/ and run the initial render.
Make sure the checklist object in settings.json has all the keys listed in the checklist below. Add any missing keys with value false (not done) or null (n/a — only for items gated on agent.digitalTwin). Persist settings.json.
Step 2 — Show the checklist
Render it like this, using the actual state from settings.json. Use [x] for true, [ ] for false, and omit lines whose value is null.
Here's your agent customization checklist. Pick a number to work on, paste a description / writeup and I'll synthesize a draft, or type 'done' to exit.
APP IDENTITY (what users see on the page)
[ ] 0. App title and greeting
WHO IS THIS AGENT?
[ ] 1. Goals, audience, success
[ ] 2. Personality and tone
[ ] 3. Methodology or framework to ground in
HOW DOES IT TALK?
[ ] 4. Conversation structure
[ ] 5. Interaction loop (reflect / elicit / self-critique / feedback)
[ ] 6. Voice traits — catchphrases, metaphors, fillers
GUARDRAILS
[ ] 7. Boundaries and refusals
[ ] 8. Knowledge base usage rules
DIGITAL TWIN (only shown if agent.digitalTwin is true)
[ ] 9. Provide source material for phrase extraction
[ ] 10. Review and finalize extracted phrases
VOICE PROFILE
[ ] 11. Custom voice setup
Ask: "Which item would you like to work on? Or paste a description / writeup of how this agent should behave and I'll draft the whole thing for you."
Step 3 — Run the chosen item or the import shortcut
If the user types a number, run that item (below). If they paste a description / writeup / Slack thread / doc snippet, run "Import shortcut" (below). After every item completes (or after a bulk update), re-render (see "Updating customization.json safely" below), then always re-display the full checklist with current [x]/[ ] state and the prompt: "Which item would you like to work on next? Or type 'done' to exit."
Items 9, 10, 11 are placeholders — tell the user those flows are coming soon and loop back.
Where the prompt comes from
Unlike the previous prose-direct model, you no longer assemble system_prompt.txt by hand. The prompt is rendered from:
agents/<projectName>/customization.json — the structured customer data you edit (persona, goals, methodology, session structure, interaction loop, voice, boundaries, knowledge-base policy, frontend copy).
templates/system_prompt/<useCase>.j2 — the platform-owned Jinja2 template that defines the prompt's structure, fixed sections (response guidelines, language protocol, etc.), and where your JSON values appear.
Available templates today: sales_coach.j2, sme.j2. The useCase field in customization.json selects the template. The schema (schemas/customization.schema.json) is the contract for what fields exist and what they mean.
Each item in this checklist writes to specific fields. When in doubt about what a field controls, check templates/system_prompt/<useCase>.j2 for the field's reference (e.g. {{ persona.tone }}) — that's where it lands in the rendered prompt.
Item 0 — App title and greeting
Ask, in order:
- "What should the app be called? (shown as the page title and in the header — e.g. 'Sales Coaching Assistant', 'Onboarding Helper')"
- "What should the agent say first when someone opens the app? (one short sentence — e.g. 'Hi! Ready to practice some sales calls?')"
Update customization.json:
persona.name ← title (this is what appears in the rendered system prompt as "You are {name}")
frontendCopy.title ← title
frontendCopy.greeting ← greeting
frontendCopy.buttonLabel ← "Talk to {title}"
Update settings.json (double-write for backward compat — deploy.js reads frontend copy from settings.json for Docker build args):
agent.title ← title
agent.greeting ← greeting
agent.buttonLabel ← "Talk to {title}"
checklist.appIdentity = true
Run ./render and confirm.
Confirm: "✓ Set title to '{title}' and greeting to '{greeting}'. These take effect on the next ./deploy."
Item 1 — Goals, audience, success
Ask, in order:
- "In one sentence, what should this agent help its users accomplish?"
- "Who is the typical user? Be specific — role, context, what they care about. (e.g. 'an enterprise seller at a systems integrator working a deal with a financial-services customer')"
- "What does a successful interaction look like? What should the user walk away with?"
Update customization.json:
persona.audience ← the audience description from question 2
persona.role ← inferred from the agent's purpose (e.g. "sales coaching assistant", "subject matter expert", "onboarding guide") — pick a short noun phrase
goals.outcome ← the goal from question 1, phrased so "Help the user {outcome}" reads naturally (e.g. "improve a real customer conversation")
goals.successDefinition ← the success description from question 3
frontendCopy.description ← "{title} is an AI-powered assistant that helps {audience} {outcome}."
frontendCopy.description2 ← "Start a conversation to {accomplish-goal-as-imperative}. {success-rephrased-as-benefit}."
Update settings.json (double-write):
agent.description ← same as frontendCopy.description
agent.description2 ← same as frontendCopy.description2
checklist.goalsAndInteractionStyle = true
Keep both description strings ≤ 200 chars and natural. Don't mention "Azure AI Foundry" or any platform brand.
Run ./render and confirm.
Item 2 — Personality and tone
Show the four dispositions and ask the user to pick one (or describe their own):
- Warm and supportive — encourages, validates, kind tone
- Direct and neutral — matter-of-fact, no fluff, information-first
- Challenging and redirecting — respectfully pushes back, asks probing questions, "tough love"
- Playful and casual — lighthearted, uses humor where appropriate
Then ask: "Anything else about the agent's voice or style? (e.g. avoids jargon, always formal, never uses emojis)"
Update customization.json:
persona.tone ← a short adjective phrase distilled from the disposition + style notes (e.g. "supportive, candid, and direct" or "clear, grounded, practical, and concise"). This phrase is woven into the "You are X" line of the rendered prompt — keep it sentence-fragment-grammatical.
If the user provided notable style rules (e.g. "never uses emojis"), capture them as one-line entries in voiceProfile.customTraits (e.g. {"label": "Punctuation", "value": "Avoids unpronounceable punctuation; never uses emojis."}). Item 6 will refine voice traits further.
Set checklist.baselinePersonalityAndTone = true.
Run ./render and confirm.
Item 3 — Methodology or framework
Ask: "Should this agent ground its answers in a specific methodology, framework, or body of knowledge? (e.g. Bloom's Taxonomy, GROW model, ITIL, SPIN selling, your company's onboarding handbook). Say 'no' if it should answer from general knowledge."
If the user says no / skip, clear methodology fields and set checklist.methodology = true.
methodology.name ← ""
methodology.summary ← ""
methodology.keyPrinciples ← []
If they name something, ask:
- "Briefly, what is it and why does it matter for this agent?" (one paragraph)
- "Are there 3-7 key concepts, stages, or principles I should bake into the prompt? (you can paste a table or list, or describe in your own words)"
Update customization.json:
methodology.name ← framework name
methodology.summary ← the one-paragraph summary. Multi-line markdown is fine (the renderer treats this field as a free-form block; tables, sub-headers, and bullet lists all render).
methodology.keyPrinciples ← array of one-line principle strings
Sales Coach extra: If useCase === "sales_coach", also ask: "Are there situations you want the agent to flag with a specific coaching question? (e.g. 'when the seller is feature-focused, ask: what outcome is your customer trying to achieve?')" Capture as coachingPrompts: [{trigger, prompt}, ...]. Each entry is {"trigger": "Feature-focused", "prompt": "What outcome is your customer trying to achieve?"}. If the user says "use the defaults" or skips, leave the existing entries alone.
Set checklist.methodology = true.
Run ./render and confirm.
Item 4 — Conversation structure
Ask: "How should a typical interaction be shaped? Pick the closest:
- Open — no fixed structure; the agent responds to whatever the user brings.
- Staged — the agent moves the user through clear stages (e.g. opening → discovery → guidance → next steps).
- Roleplay / scenario — the agent simulates a customer, interviewer, or other counter-party.
- Hybrid — describe in your own words.**"
Update customization.json.sessionStructure:
For Open:
sessionStructure.type ← "open"
sessionStructure.stages ← []
sessionStructure.description ← ""
For Staged: ask "Tell me the stages — names and what happens in each. (e.g. 1. Orientation: ask how much time and what they want from the session)"
sessionStructure.type ← "staged"
sessionStructure.stages ← array of {"name": "...", "description": "..."} entries in order
sessionStructure.description ← ""
For Roleplay: ask "Who is the agent simulating, and what should the user practice?" Synthesize a short prose block (the agent stays in character, lets the user drive, breaks character only on explicit request).
sessionStructure.type ← "roleplay"
sessionStructure.stages ← []
sessionStructure.description ← the synthesized block (rendered verbatim under # Conversation structure / # Coaching session structure in the prompt)
For Hybrid: take the user's description verbatim.
sessionStructure.type ← "hybrid"
sessionStructure.stages ← []
sessionStructure.description ← the user's description
Set checklist.conversationStructure = true.
Run ./render and confirm. Sales Coach replaces its default 4-stage block; SME inserts a new # Conversation structure section before # Explanation model.
Item 5 — Interaction loop (optional, recommended for coaches)
This is the secret sauce. It produces a self-correcting conversation that doesn't just parrot or lecture.
Ask: "Should the agent run a feedback loop on every turn? (recommended for coaching, training, or skill-development agents). If yes, the agent will reflect, ask a deepening question, have the user generate a solution, then critique it together. If no, the agent will just answer questions."
If no:
interactionLoop.enabled ← false
If yes:
interactionLoop.enabled ← true
Then ask one follow-up: "Any specific phrasing you want the agent to use in the elicit / self-critique steps? (e.g. 'walk me through how you'd...', 'if you were the customer hearing that...')"
interactionLoop.customPhrasing ← the user's phrasing string, or "" if they say no/skip. This gets inlined as a guidance paragraph after the 5-step loop in the rendered prompt.
The 5-step loop content itself (Reflect → Clarify → Elicit → Self-critique → Feedback) is platform-owned in the template, with phrasing flavored for the use case (selling concepts for sales_coach, source material grounding for sme). Don't try to write the loop steps into JSON — just toggle enabled and optionally supply customPhrasing.
Set checklist.interactionLoop = true.
Run ./render and confirm. Sales Coach shows/hides # Interaction loop + # Coaching effectiveness. SME shows/hides its teaching-flavored # Interaction loop after # Interaction patterns.
Item 6 — Voice traits
Ask:
- "Are there 3-5 short phrases or fillers you want the agent to use as acknowledgments? (e.g. 'got it', 'I hear you', 'super', 'that's cool')"
- "How does it emphasize key points? (e.g. 'repeats key words to drive the point home', 'pauses before the headline number')"
- "How does it organize ideas? (e.g. 'uses numbered frameworks', 'frames everything as before/after')"
- "Any other speaking-style rules? (e.g. 'closes with a sincere thank-you', 'never uses jargon')"
Update customization.json.voiceProfile:
acknowledgments ← array of short strings (from question 1)
emphasisStyle ← one short sentence (from question 2)
framingStyle ← one short sentence (from question 3)
customTraits ← array of {"label": "...", "value": "..."} rows (from question 4 — one row per rule)
These render as a markdown table under # Voice and delivery in the prompt: one row per trait, with customTraits rows appended after the standard three.
Set checklist.voiceTraits = true.
Run ./render and confirm.
Item 7 — Boundaries and refusals
Ask: "What topics or requests should the agent refuse or redirect? The base prompt already covers HR, unsafe content, confidential data, and prompt-extraction. List anything else you want added or any topic-specific phrasing you want — one bullet per addition. (e.g. 'Politics: respond "I can't help with that" and redirect.', 'Puzzles/riddles: do not engage.', 'Internal company info not in the KB: say so honestly.')"
Update customization.json.boundaries.customAdditions — array of one-line strings. Each string is appended verbatim after the standard refusal categories in the rendered # Boundaries section. If the user says "nothing to add", leave it as [].
Set checklist.boundaries = true.
Run ./render and confirm. Note: the base refusal categories (HR, unsafe content, confidential data, prompt-extraction) are platform-owned in the template — your additions extend them, never replace them.
Item 8 — Knowledge base usage rules
Ask:
- "What kinds of questions should trigger a knowledge base search? (e.g. 'specific Azure features, capabilities, or implementation details', 'pricing or licensing claims', 'partner-program details')"
- "How should the agent weave retrieved content into responses? (e.g. 'summarize the useful insight and cite the source briefly', 'paraphrase and avoid reading verbatim')"
- "What exact phrasing should it use when nothing is found?"
Update customization.json.knowledgeBase:
triggerDescription ← answer 1 (free-form prose; multi-line OK)
incorporationStyle ← answer 2 (short sentence)
noResultResponse ← answer 3 (exact phrasing, rendered as a quoted line in the prompt)
Set checklist.knowledgeBase = true.
Run ./render and confirm.
Items 9, 10, 11 — placeholders
If picked: "That flow isn't implemented yet — coming in a future update. For now I can help with items 0-8." Then return to the checklist.
Import shortcut
If instead of picking a number the user pastes a description, writeup, transcript, doc, Slack thread, or freeform brief, use it to populate customization.json end-to-end.
- Acknowledge: "Got it — let me extract a customization from this. I'll show you the JSON I came up with, render it, and you can tell me what to refine."
- Read everything they pasted plus
settings.json (for project name, audience hints, purpose, etc.) and customization.json (so you know the schema and current values).
- Extract structured field values, NOT prose. For each schema field (see
schemas/customization.schema.json for the full contract), pull the best signal from the user's input. If a field has no signal in the input, leave the existing value (don't overwrite with empty or with a fabricated default).
- Show the proposed JSON diff (or a summary of what changes) in chat.
- Ask: "Want me to write this to
agents/<projectName>/customization.json and render? Or refine specific fields first?"
- On approval, write
customization.json, also propagate frontendCopy.* into settings.json.agent.* (double-write), run ./render, and show the rendered diff in system_prompt.txt. Set every applicable checklist.* key to true.
- Re-display the full checklist with updated
[x]/[ ] state and the prompt: "Which item would you like to work on next? Or type 'done' to exit."
Updating customization.json safely
When writing into customization.json:
- Read the existing file first.
- Edit ONLY the fields the current item is responsible for. Preserve everything else byte-for-byte.
- Write the file back as pretty-printed JSON (2-space indent, trailing newline).
After every write, run ./render. The renderer:
- Validates the JSON against
schemas/customization.schema.json — if validation fails, it prints the missing/invalid field path. Fix and re-run.
- Re-generates
agents/<projectName>/system_prompt.txt with the AUTO-GENERATED header at the top.
Summarize what changed in the rendered prompt in one natural-language sentence (e.g., "Updated the audience and tone in the rendered prompt" or "Added a 2-stage session structure to the coaching flow"). Do NOT show a raw git diff — the full diff is noisy because the renderer regenerates the entire file. The customer can run git diff agents/<projectName>/system_prompt.txt themselves if they want the details.
Never edit system_prompt.txt directly. It is a rendered artifact and will be overwritten on the next render or deploy. If the user wants changes that the schema doesn't express, surface that as feedback — it's either a missing schema field, a missing template hook, or a candidate for the (deferred) override hatch. Don't paper over it with a manual edit.
frontendCopy.* writes also propagate to settings.json.agent.* (title, greeting, description, description2, buttonLabel). Until deploy.js reads frontend copy directly from customization.json, the settings.json mirror is what reaches the Docker build args.
When the user is done
Before showing the closing message, run the Final review at exit (silent, agentic) from the "Answer quality" section above: run ./render so you're scoring the current output, load the gold standard matching customization.json.useCase, score the ten rubric criteria internally, and — if the prompt is below the demo-ready bar — ask one targeted clarifying question, write the revision into customization.json, re-render, and re-score. Do not print scores or a score table to the user.
Once the user confirms they're good to ship:
All set. Run ./deploy (or .\\deploy.ps1 on Windows) to push your changes — title, greeting, and rendered system prompt all take effect on the next deploy. The deploy script re-runs ./render before the build, so system_prompt.txt is always fresh from your customization.json.
Rules of engagement
- Always work on one checklist item per invocation, then return to the checklist (except for the import shortcut, which fills many fields at once).
- When an item completes, immediately update
customization.json, run ./render, set the settings.json checklist flag, and confirm in chat (e.g. "✓ Marked 'Conversation structure' as complete.").
- Never edit
system_prompt.txt directly — it's a rendered artifact.
- Never overwrite fields in
customization.json that the current item isn't responsible for.
- If the user types
done, exit, or quit, show the "When the user is done" message and stop.
- The user can re-run you anytime to revisit any item.
