# Ask the codebase in Slack (https://www.shipfox.io/docs/examples/ask-codebase) Description: Answer questions about your code in Slack, with references to the files. Starts when: Someone mentions the Shipfox app in Slack. Integrations: Slack, GitHub. ## How it works 1. **Someone asks a question in Slack.** They mention the Shipfox app in a channel. 2. **The agent reads the thread and the code.** It reads the default branch and changes nothing. 3. **The agent replies in the thread.** It links the files it read and says when it is not sure. ## What it writes - Slack: Replies in the thread. ## Before you start - Connect GitHub and Slack. - Invite the Shipfox app to each channel where it answers. ## Choices you make When you set up this workflow, your coding agent asks you these questions. The workflow file on this page uses the default answers. ### What should start the workflow? - **Mention the app in allowed channels** (default): Answers every mention of the Shipfox app in the listed channels. Manual starts with thread inputs still work. - **Manual starts only**: Answers only when a Slack dispatcher or a person starts the workflow with thread inputs. Use it when a dispatcher already handles mentions, so one mention does not get two replies. ## Models When you set up this workflow, your coding agent suggests models that your workspace can use. You choose the model for each step. - `answer`: Analyzes the repository to answer the Slack thread's question with one grounded reply. Needs a strong model with high thinking. Tested with `gpt-6-sol` at high thinking. ## Set up this workflow Open your coding agent in your repository and paste this prompt. The agent needs the [Shipfox MCP server](https://www.shipfox.io/docs/how-to/set-up-work/connect-mcp-client). ```text Use Shipfox to create a workflow from the ask-codebase template. ``` The workflow file, `.shipfox/workflows/ask-codebase.yml`, with every default: ```yaml # yaml-language-server: $schema=https://www.shipfox.io/docs/workflow.schema.json # shipfox-template: ask-codebase@1 chat=slack source=github name: Answer codebase questions in Slack runner: shipfox triggers: manual: source: manual on_mention: source: slack_chat event: app_mention # Replace replace-with-channel-id with the IDs of the channels where the app answers. filter: >- !has(event.bot_id) && event.channel in ["replace-with-channel-id"] jobs: thread: checkout: false outputs: channel_id: '${{ trigger.source == "manual" ? inputs.channel_id : event.channel }}' thread_ts: '${{ trigger.source == "manual" ? inputs.thread_ts : (has(event.thread_ts) ? event.thread_ts : event.ts) }}' request: '${{ trigger.source == "manual" ?

Search and read the code to ground every claim. The checkout is read-only and the only source you have. Do not modify files, install dependencies, run builds or tests, or access the network. Choose one status: - answered: the repository answers the question. Cite each claim with a repository-relative path, and a line number when it helps, such as `src/server.ts:42`. Separate what you read from what you infer, and state any remaining uncertainty explicitly. - needs_clarification: the question is too ambiguous to search well. Ask at most two specific questions and say what you checked. - not_found: you searched and the repository does not contain the answer, for example because it depends on runtime configuration, another repository, or a decision nobody recorded. Say what you searched and where the answer might live. Do not guess. Write reply for the person who asked, in standard Markdown, under 3,000 characters. Do not mention users, groups, or channels, and do not use @here, @channel, or syntax. Do not claim that you ran code or verified runtime behavior. outputs: status: type: json schema: type: string enum: [answered, needs_clarification, not_found] reply: type: json schema: type: string minLength: 1 maxLength: 3000 - key: reply tool: send_message connection: slack_chat with: channel_id: ${{ jobs.thread.outputs.channel_id }} thread_ts: ${{ jobs.thread.outputs.thread_ts }} message: |- ${{ steps.answer.outputs.reply }} _Answered from `${{ steps.revision.outputs.repository }}` at `${{ steps.revision.outputs.commit }}`.
