Cf Ask

/cf-ask

Answer the question: $ARGUMENTS

Purpose

Quick, focused Q&A about the codebase. Proactively explores code to find the answer, then saves the Q&A to project memory so it can be referenced later.

• Unlike /cf-research: single focused answer, no multi-doc output
• Unlike /cf-remember: proactively explores the codebase to answer vs extracting knowledge already in conversation

Output: {CF_DOCS_ROOT}/memory/{category}/{name}.md. Never use relative paths in write specs (nested git repos); always {CF_DOCS_ROOT} / absolute.

Workflow

Step 0: Custom Guide

bash "${CLAUDE_PLUGIN_ROOT}/lib/load-custom-guide.sh" cf-ask

If the block above printed anything, apply only the ## Before, ## Rules, and ## After sections; if it shows the raw command instead of output, re-run that exact load-custom-guide.sh fence now.

Step 1: Parse the Question

1. Read $ARGUMENTS as the question

2. If no question provided, ask the user what they want to know

3. Identify keywords and likely relevant areas (modules, features, patterns)

4. Classify the question type — check if the question is a flow question. A flow question asks about how something works end-to-end, how components interact, or what happens when a process runs. Trigger words: "how does X work", "flow of", "lifecycle", "sequence", "process", "when X happens", "walk me through", "how are X connected", "what triggers", "what happens when", "pipeline", "chain". Non-flow questions (lookup/definition/pattern/why) do NOT trigger this path.

   Set IS_FLOW_QUESTION = true/false for use in Steps 3, 4, 5, and 6.

Step 2: Check Existing Memory (Memory Recall)

Before exploring the codebase, search existing memory docs.

Recall memory (see Verbs) with 2–3 keywords from the question: { "query": "<keywords>", "limit": 5 }; grep scope {CF_DOCS_ROOT}/memory/**/*.md, third tier = file content.

After finding matches:

Read the top 2–3 most relevant matched files before treating a hit as a direct answer.

• Direct match (same or very similar question already answered): present the existing answer (cite the file); ask if they want a fresh exploration or if it's sufficient. If sufficient → skip to Step 7 (no save).
• Related (useful background, not a direct answer): carry it to Step 3 as supplementary context.
• None → Step 3.

Step 3: Explore the Codebase (via cf-explorer agent)

Launch the cf-explorer agent to gather codebase context for the question.

Dispatch cf-explorer. Pass:

Explore the codebase to answer the following question: [question from Step 1]

Questions to answer:

1. [rephrase the user's question as specific search targets]
2. What files, functions, or patterns are relevant?
3. What are the key code snippets that answer the question?

Scope: [keywords and likely relevant areas from Step 1]

If IS_FLOW_QUESTION = true, add the following to the agent prompt:

Flow mapping required — also identify and report:

• Entry points: where does the flow start? (user action, event, API call, CLI command…)
• Actors / components: what modules, classes, functions, or services are involved?
• States / stages: what are the distinct states or phases the system moves through?
• Transitions: what triggers movement from one state/stage to the next?
• Exit points / outcomes: what are the final states or outputs?
• Error / alternate paths: are there branches, retries, or failure modes?

Organize findings as a list of states and transitions — not just a list of files.

If related memory context was found in Step 2, include it:

Existing memory context (use as supplementary info, verify against current code):

[summary of related memory findings]

Wait for the cf-explorer to return its findings.

Step 4: Form the Answer

1. Synthesize findings into a clear, structured answer
2. Incorporate any related memory context from Step 2
3. Reference specific files and line ranges where relevant
4. Use code snippets only when they clarify the answer
5. Keep it concise — this is a focused answer, not a research paper

If IS_FLOW_QUESTION: add a plain-text ASCII diagram (box/arrow characters, no Mermaid) in a fenced block — state chart, sequence lanes, or flowchart; layout rubric in references/ask-templates.md.

Step 5: Present to User

1. Show the answer directly in the conversation
2. If IS_FLOW_QUESTION = true, display the ASCII diagram inline (inside a plain fenced code block) before or after the prose — whichever gives the clearest reading order
3. List the key files that were consulted

Step 6: Save to Memory (via cf-writer agent)

1. Read language config (local .coding-friend/config.json overrides global ~/.coding-friend/config.json, default: en)
2. Search existing memory files in {docsDir}/memory/ — if an existing file covers the same topic, use task: update (append). Otherwise, use task: create.
3. Choose the appropriate category:
   • features/YYYY-MM-DD-<name>.md — for feature-specific logic, flows, APIs
   • conventions/YYYY-MM-DD-<name>.md — for project-wide patterns and rules
   • decisions/YYYY-MM-DD-<name>.md — for architecture/design decisions
4. Use kebab-case for file names

Dispatch cf-writer with the create or append spec from references/ask-templates.md (absolute file_path; append also updates updated).

Step 7: Index in CF Memory (MANDATORY)

This step is REQUIRED — do NOT skip it.

After the cf-writer agent completes and the file is saved, you MUST call the memory_store MCP tool to index the memory in the database. This is a separate action from writing the file — the cf-writer agent does NOT do this.

If creating a new memory — call memory_store with:

• title: from the frontmatter title
• description: from the frontmatter description
• type: fact
• tags: from the frontmatter tags
• content: the full markdown content (including frontmatter)
• importance: 3 (default)
• source: "conversation"
• index_only: true

If updating an existing memory — call memory_update with:

• id: the memory ID (e.g., features/auth-module — derived from {category}/{name})
• content: the updated full markdown content
• tags: updated tags array (if changed)

If the MCP tools are unavailable, log a warning to the user but do NOT fail silently — the user should know the memory was saved as a file but NOT indexed.

Step 8: Confirm

Show the user a 2-line summary:

• Markdown file: path/to/file.md (created or appended)
• Memory DB: indexed ✓ — or: MCP unavailable, file only

Rules

• Delegate exploration to the cf-explorer agent — keep the main context lean
• Stay lightweight — no multi-doc output
• Always save to {docsDir}/memory/ — saving is mandatory, not optional
• Search existing memory files before creating new ones
• NEVER overwrite existing content — only append
• Respect .coding-friend/ignore patterns
• Use language config for answer language
• Create directories as needed
