Use when creating a Browserbase Agents demo or POC, optimizing an Agent system prompt, diagnosing flaky Agent runs, or applying auto-research/autobrowse to the Browserbase Agents API.\"\nlicense: MIT\nallowed-tools: Bash Read Write Edit Grep Glob\n---\n\n# Optimize Agent Prompt\n\nOptimize a Browserbase Agent's `systemPrompt` while holding its task, result schema, variables, and evaluation criteria fixed. Treat the outer agent as the teacher and each Browserbase Agent run as an inner-agent rollout.\n\nUse Node.js 18 or later and set `BROWSERBASE_API_KEY`. The harness uses only Node.js built-in modules.\n\n## Set up the experiment\n\nChoose a short experiment name and create an isolated workspace inside the demo or POC repository:\n\n```bash\nnode <skill-dir>/scripts/optimize_agent_prompt.mjs init \\\n  --workspace ./agent-prompt-optimization/<experiment-name> \\\n  --name <experiment-name>\n```\n\nEdit the generated files:\n\n- `task.json`: keep `task`, `resultSchema`, variables, browser settings, and evaluation oracle stable across iterations.\n- `prompts/iteration-001.md`: write the minimal baseline system prompt. Include irreversible-action guardrails when applicable.\n\nUse concrete success criteria. Prefer a strict JSON Schema with required fields and `null` for unavailable facts. Add known-field regexes and factuality-warning regexes under `evaluation` when a truth oracle exists. Read [references/evaluation.md](references/evaluation.md) when designing the task or score.\n\n## Run the baseline\n\n```bash\nnode <skill-dir>/scripts/optimize_agent_prompt.mjs run \\\n  --workspace ./agent-prompt-optimization/<experiment-name> \\\n  --prompt prompts/iteration-001.md \\\n  --label iteration-001\n```\n\nThe harness creates one reusable Browserbase Agent, updates its `systemPrompt` on later iterations, starts the run, polls messages and status, and writes:\n\n```text\nruns/<label>/\n├── system-prompt.md\n├── created-run.json\n├── run.json\n├── messages.json\n├── session-logs.json\n└── summary.json\n```\n\nIt stops a run after the configured message budget instead of paying for an unproductive spiral. Use `--max-messages`, `--timeout-ms`, `--proxies`, or `--verified` only when the task needs different values from `task.json`.\n\n## Diagnose from observable evidence\n\nStart with the compact trajectory:\n\n```bash\nnode <skill-dir>/scripts/optimize_agent_prompt.mjs inspect \\\n  --workspace ./agent-prompt-optimization/<experiment-name> \\\n  --label iteration-001\n```\n\nThen read `summary.json` and drill into `messages.json` at the first wrong or wasted turn. Agent messages expose ordered tool calls, tool results, errors, and final output. A `reasoning` part may contain no readable text; never require hidden chain-of-thought for the teacher loop.\n\nRead `session-logs.json` only when browser-level evidence can distinguish the cause—for example, a redirect, 403, failed request, console error, or hidden endpoint. Empty session logs can mean the Agent completed with search/fetch tools and never drove its browser.\n\nSee [references/api.md](references/api.md) for endpoint shapes, pagination, result normalization, and trace caveats.\n\n## Improve one heuristic\n\nFind the earliest consequential failure and state one counterfactual:\n\n> If the system prompt had instructed X, the Agent would have avoided Y, as shown by tool result Z.\n\nCopy the current prompt to `prompts/iteration-NNN.md` and make one attributable change. Typical improvements are:\n\n- cap retries after a repeated block or identical error;\n- distinguish public identifiers from private/internal IDs;\n- prefer search/fetch before launching a browser when interaction is unnecessary;\n- separate current snapshots from dated historical events;\n- define when a qualified fallback counts as completed;\n- require `null` instead of guessed values;\n- add a tool-call or evidence budget.\n\nKeep wins. If the new run regresses, restore the previous prompt and test a different hypothesis rather than stacking more rules.\n\n## Judge and converge\n\nGenerate the comparison table after each run:\n\n```bash\nnode <skill-dir>/scripts/optimize_agent_prompt.mjs report \\\n  --workspace ./agent-prompt-optimization/<experiment-name>\n```\n\nJudge more than field completeness. Require:\n\n- terminal status `COMPLETED`;\n- required fields populated or explicitly nullable;\n- known-fact checks passing when available;\n- no factuality-warning match;\n- provenance and safety constraints preserved;\n- fewer messages or lower duration without quality loss.\n\nOnce a prompt wins, run it again unchanged with a new label. Converge only after it passes at least two of the last three runs and one pass is an unchanged confirmation. Do not call a prompt globally optimal from one task; describe it as the best prompt for the tested task distribution.\n\n## Graduate into the demo\n\nUse the confirmed prompt as the Agent's production `systemPrompt`. Keep the strict result schema and per-run variables. Preserve the experiment workspace or its report so reviewers can audit why each instruction exists.\n\nIn the final handoff, report:\n\n- baseline versus winning score, duration, and message count;\n- the first wrong turn each prompt change fixed;\n- whether session logs added evidence;\n- the winning prompt path;\n- confirmation-run results;\n- limitations and the next holdout matrix.\n","tagline":"Builds and improves Browserbase Agent API demos through an Autobrowse-style outer loop: run a fixed task, collect Agent messages and session logs, score the result, revise one system-prompt heuristic, and confirm convergence.
