Context Builder Cowork

Context Builder Cowork

Generates a ready-to-use project-context.md for Claude Cowork based on user answers through a structured interview. Supports two modes: full interview (15 questions across 9 blocks) and quick mode (first 3 blocks only, rest filled with placeholders).

For: anyone who works with Claude Cowork and needs a structured project context file for a new or existing project.

Language Detection

Detect the language of the user's first message — use it throughout the entire session: all interview questions, the generated file content, and section headers. Russian input → conduct interview and generate file in Russian. English input → conduct interview and generate file in English.

Input

Required:

• User's message requesting context creation (sets language and mode)

Optional:

• Keyword "quick" / "быстрый" in the trigger → activates quick mode (blocks 1–3 only, rest → [to clarify] / [уточнить])

Output

A ready-to-download project-context.md file structured across up to 9 content blocks, with [to clarify] / [уточнить] placeholders for missing information and a changelog entry with creation date.

Instructions

Step 1 — Determine mode

If the user wrote "quick context" / "быстрый контекст" → use quick mode (questions 1–8, blocks 1–3 only). Otherwise → use new mode (all 15 questions, all 9 blocks).

| Mode | Trigger | What it does | |------|---------|--------------| | new | "create project context" / "создай контекст проекта" | Full interview, all blocks | | quick | "quick context" / "быстрый контекст" | Blocks 1–3 only, rest → placeholders |

Step 2 — Conduct the interview

Ask questions in blocks, not all at once. Wait for the user's response after each block, then proceed to the next.

Block 1 — Basics

1. Project name?
2. Type: business / analytics / personal / other?
3. Status: Active / On hold / Completed?
4. Start date? Deadline (if any)?

Block 2 — Project essence

5. Describe the project in 2–4 sentences.
6. Vision — what outcome counts as project success?

Block 3 — Current stage goal

7. What are we building / working on right now?
8. What is the specific deliverable for this stage?

→ quick mode stops here. Remaining blocks are filled with placeholders.

Block 4 — Project structure

9. Describe the key elements, components, or layers of the project (freely, any format).

Block 5 — Participants and dependencies

10. Who is involved? List: stakeholders, partners, external dependencies — briefly for each.

Block 6 — Constraints

11. Are there any constraints? Time, resources, risks — what matters?

Block 7 — Data structure

12. Path to the input folder? List key files if any.
13. Path to the output folder? List already created files if any.

Block 8 — Open questions

14. Are there known open questions or unresolved tasks? (Any format works)

Block 9 — Additional sections (optional)

15. Do you need additional sections?
    - Market context
    - Methodology
    - Stages / Roadmap
    Or none of the above?

If the user selects additional sections — ask 1–2 clarifying questions for each selected section.

Step 3 — Generate the file

Processing rules:

• Do not paste user answers verbatim — write each block as coherent structured text
• Preserve the user's terminology and phrasing
• Do not invent facts — only what the user stated
• Missing or unclear items → mark as [to clarify] (EN) or [уточнить] (RU)
• Changelog: one entry with the file creation date

Output filename: project-context.md

Step 4 — Deliver the file

1. Create the file project-context.md with the generated content
2. Make it available for download
3. Briefly report: how many blocks are filled, how many are marked with placeholders

Negative Cases

• Do not activate when the user is asking about an existing project context, not creating a new one
• Do not generate the file before completing the interview
• If the user provides all information in one message — do not force an interview; assemble the file directly from the provided information
