Audit Your Context Engineering Setup

A self-contained prompt to measure and improve your Claude Code context architecture.

Author: Florian BRUNIAUX | Founding Engineer @Méthode Aristote

Reference: The Ultimate Claude Code Guide

---

1. What This Does

This prompt instructs Claude to audit your context engineering setup by:

1. Measuring total always-on context size, CLAUDE.md length, and path-scoping ratio
2. Detecting skills-to-rules balance, redundancy, and negative vs positive instructions
3. Flagging staleness signals (last updated, broken imports, deprecated references)
4. Scoring across 8 dimensions for a total of /100 with prioritized recommendations

Performance: Uses bash/grep for efficient scanning. Claude reads files only when specific content analysis is needed.

Important: Claude will NOT make any changes without your explicit approval.

---

2. Who This Is For

Level	What You Get
Solo developer	Find quick wins: trim bloat, add missing sections, fix stale imports
Small team (2-10)	Identify consistency gaps and opportunities for profile-based assembly
Large team (10+)	Systematic context architecture assessment with maturity scoring

Prerequisites:

• Claude Code installed and working
• A project with at least a CLAUDE.md or .claude/ directory
• Bash shell (native on macOS/Linux, WSL on Windows)

Time: ~3-5 minutes

Phase 2: Evaluate Across 8 Dimensions

Use the scan outputs from Phase 1. Read specific file sections only if content examples are needed for the report.

Dimension 1: Size & Budget (15 pts)

Evaluate based on token estimates from Phase 1:

Check	Points	Threshold
Total always-on context under 8K tokens	5	Sum of all CLAUDE.md + imports
Rule count under 150 instructions	5	global + project combined
No single file over 400 lines	5	flag if exceeded

Deduct points proportionally if thresholds are exceeded. A file at 600 lines = 3/5 not 0.

Dimension 2: Structure (15 pts)

Check	Points	Signal
Has an overview/purpose section	4	h2 with "overview", "purpose", "about", "context"
Has architecture or project-layout section	3	h2 with "architecture", "structure", "layout"
Includes anti-patterns or bad examples	4	"anti-pattern", "do not", "pitfall"
Section count indicates clear hierarchy	4	3+ distinct h2 sections

Dimension 3: Path-Scoping (12 pts)

Check	Points	Signal
Uses @imports for modular breakdown	5	at least 2 @import lines
At least one path-specific or glob-scoped rule	4	globs: or file-specific section
Not a monolithic file (all instructions in one block)	3	multiple files or sections

Dimension 4: Rule Quality (15 pts)

Check	Points	Signal
Ratio positive:negative >= 2:1	5	from negative/positive counts
No vague instructions detected	5	zero "be careful", "as needed", etc.
Rules are specific and actionable	5	judged from sample during report generation

Dimension 5: Freshness (12 pts)

Check	Points	Signal
CLAUDE.md committed within past 6 months	5	git log output
No deprecated tool/model references	4	deprecated scan output
No broken @imports	3	BROKEN lines in import scan

Dimension 6: Team Readiness (10 pts)

Check	Points	Signal
Has profile-based or role-based structure	4	profile mentions >= 1
Module imports enable selective assembly	3	module-imports >= 3
Documented update protocol for team	3	update-protocol >= 1

Dimension 7: Conflict Detection (11 pts)

Check	Points	Signal
No contradictory rules detected	5	no conflicts from scan
No duplicate section headers	3	no duplicates found
Session retro or knowledge loop pattern	3	session-retro >= 1

Dimension 8: Knowledge Loop (10 pts)

Check	Points	Signal
Has update/review protocol documented	4	update-protocol >= 1
Has session retro or lesson-learned pattern	3	session-retro >= 1
Context tracked in git (auditable changes)	3	git freshness scan shows commits

Calculate Total Score

Score = sum of earned points across all 8 dimensions

Phase 3: Generate Report

Structure your output exactly as:

Context Engineering Audit

Score: [XX]/100

Dimension	Score	Notes
Size & Budget	X/15	total ~X tokens, X rules
Structure	X/15	X sections, has/missing overview
Path-Scoping	X/12	X imports, monolithic/modular
Rule Quality	X/15	X% positive, X vague found
Freshness	X/12	last updated X, X broken imports
Team Readiness	X/10	X profiles, update protocol: yes/no
Conflict Detection	X/11	X contradictions, X duplicate headers
Knowledge Loop	X/10	git tracked: yes/no, retro: yes/no

Context Budget

• Global CLAUDE.md: ~X tokens
• Project CLAUDE.md: ~X tokens
• @imports combined: ~X tokens
• Total always-on: ~X tokens
• Rule count: X/150 instructions

Priority Issues (fix these first)

1. [Issue] — [specific fix with example]
2. [Issue] — [specific fix with example]
3. [Issue] — [specific fix with example]

Quick Wins (< 30 min each)

• [Fix]: [what to do and where]
• [Fix]: [what to do and where]
• [Fix]: [what to do and where]

Maturity Level

[Choose one and explain why]

Level 1 — Empty (0-19): No structured context. Claude operates with zero project knowledge. Level 2 — Basic (20-39): CLAUDE.md exists but is monolithic, stale, or mostly vague rules. Level 3 — Structured (40-59): Clear sections and imports, but missing freshness or team patterns. Level 4 — Optimized (60-79): Modular, scoped, positive-first rules with a known update cadence. Level 5 — Engineering-Grade (80-100): Profile-aware, git-tracked, conflict-free, knowledge loop active.

Ready-to-use Improvements

Provide 2-3 concrete text blocks that users can paste directly into their CLAUDE.md. Each block must address a Priority Issue identified above. Format:

Improvement 1: [name] File: [path] — add at [top/section X/end]

[exact text to paste]

Improvement 2: [name] File: [path] — add at [top/section X/end]

[exact text to paste]

---

Phase 4: Await Validation

CRITICAL: Do NOT create or modify any files without explicit approval.

After presenting the report, ask:

"Which improvements would you like me to implement?

Options:

• all — Apply all ready-to-use improvements
• 1, 2 — Specific improvements by number
• priority — Only Priority Issues fixes
• none — Keep the report for reference only

Please specify your choice:"

Wait for explicit user response before taking any action.

Output Format

Structure your response exactly as:

1. Score table with dimension breakdown
2. Context Budget summary
3. Priority Issues (numbered, fix first)
4. Quick Wins (bullet list, < 30 min each)
5. Maturity Level with explanation
6. Ready-to-use Improvements (paste-ready text blocks)
7. Validation Request (ask before implementing)

## 5. What to Expect

Here's an example of what the audit report looks like:

### Example Score Table

Context Engineering Audit

Score: 52/100

Dimension	Score	Notes
Size & Budget	10/15	~6,200 tokens total, 182 rules (over limit)
Structure	9/15	4 sections, no anti-patterns section
Path-Scoping	4/12	1 import, monolithic project CLAUDE.md
Rule Quality	8/15	60% positive, 3 vague instructions found
Freshness	9/12	last commit 4 months ago, 1 broken import
Team Readiness	3/10	no profiles, no update protocol
Conflict Detection	6/11	1 "always/never" contradiction, no duplicate headers
Knowledge Loop	3/10	not git tracked, no retro pattern

### Example Quick Wins

Quick Wins (< 30 min each):

• Fix broken import: @~/.claude/TONE.md not found — update path or remove
• Add overview section: 2-line project description at top of CLAUDE.md
• Trim rule count: merge 3 formatting rules into one compressed block

---

## 6. Scoring Guide

| Score | Maturity | Recommended Action |
|-------|----------|--------------------|
| **80-100** | Level 5: Engineering-Grade | Maintain with quarterly review |
| **60-79** | Level 4: Optimized | Address priority issues, reach 80 |
| **40-59** | Level 3: Structured | Dedicate a session to improvement |
| **20-39** | Level 2: Basic | Restructure recommended, use template |
| **0-19** | Level 1: Empty | Start fresh with skeleton template |

---

## 7. Glossary

| Term | Definition |
|------|-----------|
| **Always-on context** | Everything Claude loads before your first message: CLAUDE.md files plus all @imports |
| **@import** | A line starting with `@` in CLAUDE.md that loads another file into context |
| **Path-scoping** | Applying rules only to specific file types or directories, not globally |
| **Rule quality** | Specificity and actionability of instructions — vague rules waste tokens and confuse Claude |
| **Knowledge loop** | The practice of updating context files after sessions based on what worked and what didn't |
| **Profile assembly** | Combining different context modules to create role-specific setups (junior, senior, reviewer) |
| **Staleness signal** | Indicators that context is outdated: broken imports, deprecated model names, no git history |
| **Conflict** | Two rules that contradict each other — Claude will pick one arbitrarily, usually the wrong one |
| **Monolithic CLAUDE.md** | A single large file with all instructions, no imports, no modular breakdown |
| **Maturity level** | A 1-5 scale measuring context engineering sophistication from empty to engineering-grade |

---

## 8. Common Issues

### "Token estimate seems off"

**Cause**: The estimate uses chars/4 as a rough proxy for GPT-style tokens. Claude's tokenizer may differ slightly.

**Fix**: Focus on relative numbers and thresholds rather than absolute token counts. The 8K always-on budget is a heuristic, not a hard limit.

### "Score is low but Claude seems to work fine"

**Cause**: Claude works without context engineering — the score reflects optimization, not basic functionality.

**Fix**: A low score means you're leaving productivity on the table. Each dimension gap adds cognitive overhead per session.

### "Broken import flagged but file exists"

**Cause**: Relative path resolution differs from Claude's actual working directory at startup.

**Fix**: Use absolute paths (`~/.claude/file.md`) for global imports. Use project-relative paths (`./docs/conventions.md`) for project imports.

### "Profile-readiness flagged but I'm solo"

**Cause**: The audit checks for team-scalability patterns regardless of team size.

**Fix**: Profile-based assembly still benefits solo developers when switching contexts (reviewing PRs vs writing features vs debugging). It is optional for solo use.
