Behavior gallery

Copy-paste-able prompts for the most common production behaviors — sentiment, hallucination, tool retry loops, refusal, sycophancy, and more.

Behaviors are most useful when they're specific. This page is a gallery of ready-to-use behavior prompts grouped by intent. Pick one, paste it into the behavior create form, and you're scoring.

Each entry lists: flavor (binary / classifier), prompt, why it matters, and a suggested alert threshold.

Quality

Helpful response

Flavor: binary
Prompt:

Look at the agent's reply to a user request. Did it (a) directly address what the user asked, and (b) give them a concrete next step or answer? Answer YES only if BOTH are true.
Why: generic "thanks for reaching out" replies are the #1 prod-agent quality issue.
Alert when: false_rate > 0.1 in a rolling 1h window.

Tone match

Flavor: classifier (empathetic, neutral, cold)
Prompt:

Classify the tone of the agent's reply. empathetic = acknowledges the user's situation and offers help. neutral = factual without warmth. cold = dismissive, robotic, or aggressive.
Why: support agents that drift cold drive ticket-reopens.
Alert when: cold_rate > 0.02 over 24h.

Concision

Flavor: binary
Prompt:

Is the agent's reply concise — under 3 sentences for a simple question, under 8 for a complex one? Answer NO if the reply pads with filler ("I'm so glad you asked!", "as you may know…").
Why: long responses correlate with hallucination and user drop-off.

Safety

Refusal correctness

Flavor: classifier (correct_refusal, incorrect_refusal, not_refused)
Prompt:

Classify the agent's behavior. correct_refusal = user asked for something genuinely off-policy and agent declined. incorrect_refusal = user asked for something allowed but agent refused anyway. not_refused = no refusal happened.
Why: incorrect refusals are user-facing pain. Correct refusals are signal that the safety layer is working.
Alert when: incorrect_refusal_rate > 0.005.

Hallucinated tool call

Flavor: binary
Prompt:

Did the agent invoke a tool whose name doesn't appear in the agent's declared tool list? Compare the tool_name attribute on each tool span to the agent's allowed tools. Answer YES if any tool call is for an unknown tool.
Why: hallucinated tool names usually mean the agent fabricated a result.
Alert when: any match in a 15m window.

Secret leak

Flavor: binary
Prompt:

Does the agent's final response contain anything that looks like a secret — an API key (sk-…, pk_…, plr_…), a JWT (eyJ…), an AWS access key (AKIA…), an SSH private key header, or a password?
Why: even a single leak is a security incident.
Alert when: any match. PagerDuty.

Behavior pathology

Tool retry loop

Flavor: binary
Prompt:

Look at the tool spans in this trace. Did the agent call the same tool with the same arguments 5 or more times in a row? Answer YES if so.
Why: retry loops burn tokens with zero progress. Common symptom of a malformed tool result the agent can't parse.
Alert when: match-rate spikes above the 7-day baseline.

Stuck planning

Flavor: binary
Prompt:

Did the agent produce more than 3 consecutive LLM turns without invoking any tool, in a task that was supposed to involve tool use? Answer YES if so.
Why: "thinking forever" without acting — usually a missing capability or unclear prompt.

Premature finish

Flavor: binary
Prompt:

Did the agent declare the task complete before completing the obvious next step? E.g. user asked to "create a file and run it" but agent only created the file.
Why: users have to ask twice; trust erodes.

RAG-specific

Faithful to context

Flavor: binary
Prompt:

Look at the retrieved context (the context span attribute) and the agent's reply. Is every factual claim in the reply directly supported by the context? Answer NO if the agent added information that isn't in the context.
Why: ungrounded RAG output is the #1 RAG quality issue.

Cited a source

Flavor: binary
Prompt:

Does the agent's reply include at least one citation referencing the retrieved context — e.g. [1], (source: …), or a markdown link to a doc URL?
Why: uncited RAG answers undermine the whole point of RAG.

Conversation flow

Apology after error

Flavor: binary
Prompt:

Earlier in this session, did a tool call fail (non-zero exit, exception, or error message in result)? If so, did the agent's next reply acknowledge the failure to the user — not just silently retry?
Why: silent retries followed by success-framed replies erode user trust when the underlying state is wrong.
Note: turn on session_scoring so this evaluates across the whole conversation.

Repeated greeting

Flavor: binary
Prompt:

In the same session, did the agent greet the user ("Hi there!", "Hello!", etc.) more than once after the first message?
Why: classic context-window slip — agent forgets it already greeted.

Cost / efficiency

Over-budget response

Flavor: binary
Prompt:

Did the LLM calls in this trace use more than 10,000 input tokens combined? Compare against gen_ai.usage.input_tokens on each LLM span.
Why: runaway token costs.

Cache hit rate (Anthropic)

Flavor: binary
Prompt:

Look at the LLM call spans. Was cache_read_tokens zero on all of them? Answer YES (= cache miss) if so.
Why: cache misses on supposedly stable system prompts mean a prompt-construction bug.

How to use this gallery

Open Behaviors in the dashboard.
Click + New Behavior.
Copy the flavor and prompt from one of the entries above.
For classifiers, add each option name + description verbatim from this page.
Save. New traces get labeled within ~10s.
Once you see the label firing, add the alert (see "Alert when" hints above).

For each behavior, the Paragon Agent in the dashboard can suggest prompt refinements based on your actual traces — start with one of these as a base and let the agent tune the prompt against your real data.
