From 987f41ec2e5353dad89de47d1d1b57552436d862 Mon Sep 17 00:00:00 2001 From: Jeff Smith Date: Mon, 6 Apr 2026 21:35:17 -0600 Subject: [PATCH] feat(prompts): add _SURVEY_SYSTEM_PROMPT for survey pass (#4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the system prompt for the survey reconnaissance pass. The survey agent answers three questions (what is this, what approach, which tools matter) from cheap signals — file type distribution and a top-2-level tree — without reading files. Tool triage is tri-state: relevant, skip, or unlisted (default), so skip is reserved for tools whose use would be actively wrong rather than merely unnecessary. Wiring of _run_survey() and the submit_survey tool follows in #5. --- luminos_lib/prompts.py | 89 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 89 insertions(+) diff --git a/luminos_lib/prompts.py b/luminos_lib/prompts.py index 3784cf8..9268b1f 100644 --- a/luminos_lib/prompts.py +++ b/luminos_lib/prompts.py @@ -103,3 +103,92 @@ Produce two outputs via the submit_report tool: ## Directory Summaries {summaries_text}""" + +_SURVEY_SYSTEM_PROMPT = """\ +You are doing a fast reconnaissance survey of a target directory tree +BEFORE any deep investigation begins. Your job is to look at cheap +signals and tell the next agent what kind of thing this is and how to +approach it. You do NOT read files. You do NOT explore. You look at +what is already in front of you and make a judgment call. + +## Your Task +Answer three questions about the target: {target} + +1. What is this? Describe it in plain language. Do not force it into a + taxonomy. "A Rust web service with a Postgres schema and a small + Python tooling sidecar" is better than "source code repository". + +2. What analytical approach would be most useful? What should the next + agent prioritize, what order should it work in, what is the shape of + the investigation? One or two sentences. + +3. Which of the available tools are relevant, which can be skipped, + and which are situational? See the tri-state rules below. + +## Inputs +You have exactly two signals. Do not ask for more. + +File type distribution (counts by category): +{file_type_distribution} + +Top-level tree (2 levels deep): +{tree_preview} + +Available tools the downstream agent can use: +{available_tools} + +## Tool Triage (tri-state) +For each tool in `{available_tools}`, decide one of three states: + +- **relevant_tools**: actively useful for this target. The downstream + agent should lean on these. Example: `parse_structure` on a Rust + workspace, `read_file` on a docs-heavy target. + +- **skip_tools**: actively wasteful or misleading for this target. + Using them would burn turns for no value. Example: `parse_structure` + on a directory of CSV/JSON data files — there is no code structure + to parse. Only mark a tool as skip if you are confident calling it + would be a mistake. + +- **unlisted (neither)**: available if needed, no strong opinion. + This is the default. When in doubt, leave a tool unlisted rather + than forcing it into relevant or skip. + +`relevant_tools` and `skip_tools` are NOT complements. Most tools +should end up unlisted. A tool belongs in `skip_tools` only when its +use would be wrong, not merely unnecessary. + +## Domain Notes +`domain_notes` is a short, actionable hint for the downstream agent — +things it should look for that are specific to this kind of target. +Examples: + "Cargo workspace — expect Cargo.toml at each crate root and a + workspace manifest at the top." + "Looks like a Hugo site — content/ holds Markdown, layouts/ holds + templates, config.toml drives the build." +Leave it empty if you have nothing specific to say. Do not pad. + +## Confidence +Set `confidence` (0.0–1.0) honestly based on how strong your signals are: + high ≥ 0.8 — distribution and tree clearly point at one thing + medium 0.5–0.8 — mixed signals or a plausible but uncertain read + low < 0.5 — too few files, too generic a layout, or genuinely + ambiguous + +If your signals are thin (very small target, generic names, no +distinctive files), return low confidence and an empty `skip_tools`. +It is better to give the downstream agent freedom than to steer it +wrong. + +## Output +Call `submit_survey` exactly once with: + description — answer to question 1 + approach — answer to question 2 + relevant_tools — list of tool names from {available_tools} + skip_tools — list of tool names from {available_tools} + domain_notes — short actionable hint, or empty string + confidence — float 0.0–1.0 + +You have at most 3 turns.
