Setup Installed Ochat, a configured provider with access to gpt-4.1 (or an edited supported model), and launch from the extracted directory. Model requests incur provider charges.
One project. Two agents. A useful review.
Inspect the recorded workflow
An explorer reads the setup guide. A specialist finds the gaps. You get findings you can act on.
A clearer path for new contributors.
The sample Lantern guide leaves its runtime version, setup commands, and checks unspecified.
Read the model’s report, then inspect the calls and files behind it.

A small documentation site for a software project.
## Requirements
Install a recent Node.js release. Use whichever package manager you prefer.
## Setup
Install the dependencies, then start the preview.
## Check your changes
Run the usual checks before opening a pull request. Make sure everything works.

Captured with OpenAI gpt-4.1 on synthetic sample documentation. A new run can produce different results.
Recording details and reproduction
Real Ochat batch driver, scoped file read, and nested specialist; synthetic Lantern documentation only. Model responses recorded from OpenAI. Results vary on a new run.
Recording proxy converts complete responses to stream events and normalizes response-envelope metadata; model output is unchanged.
Playback advances through captured steps; its timing is illustrative. Temporary directory paths are redacted. No credentials are included.
From the Ochat checkout, reproduce an offline run with python3 website/scripts/record-showcase.py. Add --live to use the configured OpenAI key for at most six model requests and replace the capture with a live run.
Let an explorer gather the context and a specialist identify what a new contributor needs.
Give the reviewer its own instructions, then reuse it from other agents. Inspect the complete recorded run.
The outcome
Section titled “The outcome”Input: The sample Lantern setup guide.
Output: Three concrete findings and a next action.
Inspect the workflow
Section titled “Inspect the workflow”The explorer reads the included Lantern setup guide and passes its contents to
docs-reviewer.chatmd. The specialist has its own instructions and no tools.
The explorer turns that feedback into a report for the maintainer. Neither
agent can edit files or run shell commands.
Use the execution viewer above to inspect the captured calls and their results. The recording identifies its provider and scope. The original ChatMD transcript is included with the source files below; a new model run can produce different wording and findings.
Run it yourself
Section titled “Run it yourself”Complete installation and provider setup. Extract the documentation-review bundle and launch from its directory:
mkdir -p runsochat chat-completion -prompt-file explorer.chatmd -output-file runs/review-01.chatmdThe prompt already contains the request. Use a fresh output filename for each
independent run; an existing file participates in the batch resume workflow.
Both prompts select gpt-4.1; choose an available supported model in both if
needed. Model work, including the specialist, incurs provider charges.
What a useful result contains
Section titled “What a useful result contains”Check that findings refer to the supplied requirements, setup, or verification sections. Missing commands should be identified as missing, not invented. The maintainer decides which corrections are accurate before changing documentation.
Adapt the reviewer
Section titled “Adapt the reviewer”Replace the sample input, update the read root, and give the specialist your review checklist. To turn findings into proposed edits, add editing tools as an explicit next step and review the resulting diff. Follow the specialist tutorial to understand relative paths and what context the child actually receives.

concrete obstacles for a new contributor. For each, quote a short passage,
explain the problem, and suggest a correction without inventing commands or
requirements. Cite reference/project.txt and its section. Return a concise

Concise Report: Barriers for New Contributors
1. Missing Commands for Setup
The documentation states, "Install the dependencies, then start the preview," but does not specify what commands to use (e.g., `npm install`, `yarn start`). This lack of detail may prevent new contributors from proceeding.
(Source: reference/project.txt, "Setup")
2. Unclear Testing/Checking Process
The suggestion to "run the usual checks" before making a pull request is too vague. New contributors may not know which scripts or tools to use, or what constitutes a complete check.
(Source: reference/project.txt, "Check your changes")
3. Undefined Node.js Version Requirement
"Install a recent Node.js release" does not clarify which versions are supported. Using an incompatible version might cause errors, confusing contributors.
(Source: reference/project.txt, "Requirements")
Suggested Next Action:
Update the setup documentation to clearly list the exact commands for installing dependencies and starting the preview, clarify how to run project checks, and specify the supported Node.js version(s).
