build-user-profile

build-user-profile is a skill for Claude Code from truenorth-lj/adaptive-agent-skill. It costs 53 tokens per session (825 once invoked), scanned A, original, MIT.

A skill that builds or updates a remembered profile of the user from workspace files, Git history, project structure, technology choices, and conversation patterns. Git is a system that records changes to code and project files.

In plain words
What is it for?
Creating or refreshing user-profile memory and checking whether the agent's stored understanding still matches the workspace.
Why use it?
It gives the agent context about the user's projects, tools, interests, and preferences without relying only on the current conversation. It is intended for first use, stale profiles, or major project changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

build-user-profile scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Build User Profile

Actively build and maintain a user profile in the agent's memory system.

When to Run

  • First session in a new workspace — bootstrap the profile from observable context
  • Profile feels stale — interests, focus areas, or tech stack have shifted
  • User explicitly asks to update their profile
  • After major project changes — new repo added, tech stack shift, role change

Step 1: Gather Observable Context

Collect signals from the workspace without asking the user. Run these in parallel:

1a. Git identity and activity

git log --all --format='%an <%ae>' | sort -u
git log --oneline -50 --all
git log --since='30 days ago' --oneline --all | head -20

1b. Project structure

ls -d */ 2>/dev/null
cat *.yaml *.yml 2>/dev/null | head -50

1c. Tech stack signals

Look for package.json, requirements.txt, go.mod, Cargo.toml, pyproject.toml, or similar. Read framework choices.

1d. Existing memory and feedback patterns

Check for memory files or CLAUDE.md that reveal preferences.

1e. Content signals

Check for blog posts, research docs, or README content that reveals interests.

Step 2: Read Existing Profile

Read the current user profile memory file if it exists. Note what's already captured and what might be outdated.

Step 3: Synthesize Profile

Build or update the profile with these sections:

---
name: {User} User Profile
description: {one-line} — used to tailor collaboration approach
type: user
---

## Role & Focus
- What they do, what projects they're working on

## Technical Strengths
- Languages, frameworks, tools they're strong in
- Areas they're learning or new to

## Work Style
- Autonomy level (do they want to be asked, or just do it?)
- Pace (ship fast vs deliberate?)
- Research habits (deep-dive vs pragmatic?)

## Communication Preferences
- Language preferences
- Verbosity (concise vs detailed?)
- Format preferences (tables, bullet points, prose?)

## Current Interests
- What they're researching or exploring right now
- Include date for staleness detection, e.g. (2026-04)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
