How to Give Claude Context Without Overloading the Chat

To give Claude context, state what you want to accomplish, supply the sources needed for that task, and separate settled decisions from open questions. Add where the work stands and ask Claude to confirm its next step before it starts. You need a useful starting point, not a transcript of everything that happened.

Tools like fenbs keep current project context outside a single chat, so a new session can start from the same rules and progress. You can also begin with a plain note and a few carefully chosen attachments. The method matters more than how impressive the collection looks.

What should you give Claude first?

1. Define the immediate outcome. Say who will use it and what a good result includes: a draft email, a comparison table, a revised design or a tested code change.
2. Provide the evidence. Attach or identify the source that supports each important requirement. Name the relevant page, section or file rather than asking Claude to discover your priorities.
3. State the decisions and constraints. Identify what people approved, what must stay unchanged and what needs permission. Explain the reason when it affects the work.
4. Describe the current state. Say what already exists, what was checked, what failed and what remains uncertain. Keep an unfinished experiment distinct from the approved approach.
5. Request a short understanding check. Ask Claude to state the goal, applicable constraints, missing evidence and its proposed first step. Correct that account before continuing.

For example, a designer revising a nonprofit donation page might supply the approved copy, the current screenshot and the requirement to preserve the donation form. The entire organization history is unnecessary. A useful check is whether a new colleague could begin the same task from those materials without guessing.

Anthropic recommends clear instructions, explicit output constraints and enough motivation to explain what matters in its prompting guidance↗ (opens in a new tab). You do not need elaborate formatting to make those choices clear.

How can you make a compact starting note?

Use labeled fields so the request, evidence and boundaries are easy to tell apart. A short note should still be specific enough to act on. “Help with the website” gives no audience, source of truth or stopping point; “revise this donation-page introduction for first-time donors” provides a much firmer start.

Goal: Revise the donation-page introduction for first-time donors.
Output: Two alternatives, each under 90 words, with a reason for each.
Sources: Approved-copy.pdf, introduction section; current-page.png.
Decided: Keep the existing donation form and the approved program name.
Current state: The layout is approved; the introduction still needs review.
Unknown: Whether recurring gifts should be mentioned. Ask before assuming.
First: Confirm the relevant sources and summarize the constraints.

Label examples as examples. If you paste an old campaign email to demonstrate tone, say that its dates, offers and claims should not be reused. Otherwise, you leave Claude to distinguish stylistic guidance from factual evidence. A single sentence about why a source is included often prevents several rounds of correction.

Keep exact wording when exact wording matters. A product name, approved disclaimer or acceptance condition should appear verbatim with its source. Background that only explains the situation can be summarized in your own words. This is a practical way to shorten context without weakening the requirements.

Should you paste text or attach a file?

Paste a short passage when Claude needs only that passage, and include its title and version. Attach a document when surrounding sections matter or when the answer must reference several parts. Anthropic documents both chat attachments and persistent project files in its file upload guide↗ (opens in a new tab); check that page for current formats and limits.

For recurring work, Claude Projects provide a place for project knowledge and instructions, as described in Anthropic’s project overview↗ (opens in a new tab). Keep today’s request in the chat so it remains clear what you want done now. The existence of a project is not a substitute for naming the task.

Supplying whole manuals and checking file access are separate jobs; the guide to giving Claude documentation covers those details. If you work in a repository, context engineering for Claude Code explains how to connect the request to the code being changed.

How do you check whether Claude understood?

Ask a question whose answer requires using the supplied material. In the donation-page example, ask which wording must remain and which file establishes it. A general “I understand” tells you little. A short explanation tied to the source gives you something concrete to check.

• Can Claude identify the current version rather than an older example?
• Does it distinguish a requirement from a suggestion?
• Can it say what is still unknown without inventing a likely answer?
• Does its proposed first step fit the task you actually assigned?

When an answer misses a constraint, correct the source note as well as the immediate reply. If “preserve the form” meant preserve its fields but allow visual changes, write that distinction explicitly. Repeated corrections often reveal ambiguous instructions that another session would struggle with too.

What should you leave out of the next request?

Leave out abandoned options unless their rejection affects today’s choice. Keep unrelated tasks in separate sessions. Remove copied conversations that repeat the same decision in several conflicting ways. A clean account of what was chosen is more useful than a long debate with no marked conclusion.

Do not remove uncertainty to make the note sound tidy. “The wording is approved; the accessibility review is pending” gives the next session a realistic boundary. If you need broader background on the product surfaces, start with what Claude is or what Claude Code is, rather than mixing their setup assumptions.

How to do this with fenbs

1. Create a free account, then add the project and the immediate task to your kanban board.
2. Write the goal and relevant background as project context. Record people’s approved instructions in Decisions and rules, leaving unresolved choices open.
3. Follow the Claude setup guide in Integrations. The connection uses MCP, a standard way for an AI app to use an outside tool, with browser sign-in.
4. Ask Claude to read the project context and explain its starting point. When the session ends, save what changed, what was checked and what the next session should do.

fenbs is useful when context changes across tasks, sessions or assistants. It is unnecessary for a single short question, and it does not read your Claude chat history or import it automatically. Begin with the next fact you would otherwise need to explain again; the context engineering hub covers the wider practice.
