What This Is

Most AI agents in large codebases fail in the same ways: they hallucinate structure, waste tokens re-reading files they've seen before, and make changes without knowing what will break. This system solves all three.

It works by pre-computing a structural dependency graph (SQLite, AST-based, zero LLM) of your entire codebase once, then giving every AI agent — Claude Code, Cursor, Gemini CLI, GitHub Copilot — a precise manual for how to work in your specific project. From that point on, structural questions are answered from the graph in milliseconds, not from re-reading source files.

What You Get After Install

This system integrates directly with Claude Code, Gemini, and other AI tools as an on-demand skill, feeding them structured repo context and enforcing local guardrails. Answering structural questions via our pre-computed graph saves 70–90% of LLM tokens per query.

1. Unified Codebase Intelligence Hub (.wednesday/)

• AST-parsed Dependency Graph (graph.db): Builds and maintains a SQLite database mapping every import, export, and function call across JS, TS, Python, Go, Swift, etc. This eliminates the need for AI agents to repeatedly read files, reducing LLM token consumption by up to 90%.
• Living Agent Configuration Files: Automatically generates and updates CLAUDE.md, GEMINI.md, .cursorrules, and .github/copilot-instructions.md with available skills and rules.

2. Guardrails and Enforced Quality Standards

• Complexity Gates: Enforces a cyclomatic complexity limit of 8 before code is submitted.
• Approved Design Assets: Enforces UI design rules, preventing developers or AI agents from creating custom/duplicate UI components and restricting imports to approved libraries (e.g. shadcn, Magic UI).
• Git and Commit Discipline: Automatically installs git hooks:
  • commit-msg: Enforces conventional commit formatting via commitlint.
  • pre-commit: Requires a @wednesday-skills:purpose header on new files.
  • post-commit / post-merge: Automatically maintains and syncs the dependency graph in < 1s using incremental updates.

3. Immediate Change & Impact Analysis

• Blast Radius Analysis (blast <file>): Instantly lists direct and transitive dependents that will be affected if a specific file or symbol changes.
• Audit-ready Safety Scoring (score <file>): Computes a detailed file risk score from 0 to 100 using import volume, public contracts, test coverage, and historical git bug history.

4. Automated Multi-Agent Architecture Planner (plan)

• Parallel Synthesis: Triggers a parallel planning pipeline running PM, Architect, and Security personas simultaneously on any project brief. It resolves technical disagreements (tensions) and synthesizes a production-ready PLAN.md outlining phase breakdowns, JWT auth strategies, and threat mitigations.

5. Seamless Skill Registry & Cost-Optimized Analytics

• On-Demand Package Management: Use ws-skills search and ws-skills add to pull community-built skills. Enforces PR review fixes (@agent fix all) as atomic commits with zero friction.
• Up to 99% Cost Savings: Structural queries are automatically routed to free-tier fallback models (Gemma 3, Qwen 2.5) first, saving up to 99% on API bills (reducing a $0.1620 Sonnet analysis query down to $0.0013). Run ws-skills stats --cost to inspect monthly cost breakdowns locally.

Why Use This

For AI Agents

Without this system	With this system
Reads 20 raw files to answer "what does auth do?" — 6,000 tokens	Queries graph.db — 0 tokens
Guesses at dependency structure	BFS traversal on verified AST edges
Makes changes with no risk context	Checks blast radius before touching anything
Forgets conventions between sessions	Reads enforced rules from CLAUDE.md / .cursorrules on every turn
Produces inconsistent commit messages	Every commit enforced by commit-msg hook via commitlint

For Development Teams

Speed — New AI agents (and new developers) are productive on day one. MASTER.md gives full architectural context without reading a single source file.

Safety — High-risk files (risk score > 80) trigger a mandatory review pause before any AI is allowed to edit them. Blast radius is computed before the first keystroke.

Cost — Pre-computed graphs reduce LLM token spend on structural questions by 70–90%. Every map run prints a breakdown:

━━━ Token Usage Report ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Command:       map
  LLM calls:     18   (6 cache hits → 0 tokens)
  Tokens used:   9,240  (in: 6,800 / out: 2,440)
  Baseline est:  54,000  (cost of reading raw files)
  ▼ 44,760 tokens saved  (82%)
  Cost:          $0.0013  (baseline: $0.1620 vs Claude Sonnet)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Consistency — All AI tools (Claude, Gemini, Cursor, Copilot) follow the same standards because they all read from the same source. No more "Claude lets me do X but Cursor blocks it."

Clean git history — Conventional commits enforced at the hook level. Every PR follows the same shape.

Installation

Requirements: Node.js ≥ 18

# Option 1 — npx (no setup)
npx @wednesday-solutions-eng/ai-agent-skills install

# Option 2 — global
npm install -g @wednesday-solutions-eng/ai-agent-skills
wednesday-skills install

# Option 3 — shell (no npm)
bash install.sh

Run in your project root. The installer:

1. Copies skills into .wednesday/skills/
2. Writes CLAUDE.md, GEMINI.md, .cursorrules, .github/copilot-instructions.md
3. Installs git hooks: commit-msg, pre-commit, post-commit, post-merge
4. Symlinks skills into .claude/skills/ for Claude Code's skill picker
5. Writes .commitlintrc.json with GIT-OS conventional commit rules

No API key needed when using skills inside Claude Code, Cursor, or Gemini CLI. The IDE is the intelligence engine — skills are standard markdown instructions.

API keys are only needed for standalone CLI commands (map, summarize, gen-tests):

wednesday-skills config        # interactive setup wizard

Or add to .env:

OPENROUTER_API_KEY=...         # cheaper, recommended (Gemini Flash-Lite default)
ANTHROPIC_API_KEY=...          # fallback
GITHUB_TOKEN=...               # for dashboard PR data

---

How to Use It

Day 1 — Map the Codebase

wednesday-skills map --full

This runs the full pipeline: AST parse → dependency graph → module summaries → MASTER.md. On a 500-file codebase it takes ~2 minutes and costs under $0.01 using Gemini Flash-Lite.

After this, the graph auto-updates on every commit. You never run map again unless you want a full refresh.

Every Day — Just Talk to the AI

Once mapped, your AI agent already knows the codebase. Open Claude Code or Cursor and ask naturally:

Understanding the codebase:

"Walk me through how a payment is processed."
"What does the auth middleware do?"
"Who owns the billing module?"

Before making a change:

"Is it safe to change the signToken function signature?"
"What breaks if I rename UserService?"

Starting a new task:

"Start ticket: Add rate limiting to the login endpoint."
→ Creates branch feat/rate-limiting-login
→ Prints PR description template
→ Enforces atomic commits throughout

PR workflow:

"@agent fix #2 and #4"          # fix specific review comments
"@agent fix all"                 # fix everything in the queue

After shipping:

"Run pre-deploy checklist for the auth service."
"Generate an onboarding guide for the payments module."

Scenarios

Inheriting a Legacy Codebase

You: "Map this codebase completely."

AI runs wednesday-skills map --full. After 2 minutes you have:

• MASTER.md — full architecture in plain English
• Risk scores on every file (0–100)
• Circular dependency report
• Dead code finder
• Module ownership from git blame

From this point, any structural question is answered from the graph, not from re-reading files.

---

Fixing a Bug in a High-Risk Module

You: "Fix the token expiration bug in auth.ts."

AI checks blast radius before writing a single line. If risk score > 80:

⚠ HIGH RISK — auth.ts has risk score 87
  This file is imported by 14 modules across Auth and Billing.
  Recommend running these 3 tests before editing: [list]
  Proceed? (y/n)

Only after your confirmation does it write code — then commits with fix(auth): Resolve token expiry on silent refresh.

---

New Developer Onboarding

You: "Generate an onboarding guide for the payments module."

AI uses recursive SQL traversal on graph.db to trace the full request path from API entry point to database layer, producing a focused Mermaid diagram and file reading order — specific to the exact layer the developer needs to touch.

---

Architecture Review Before a PR Merge

You: "Check if this PR follows our architecture."

brownfield-drift reads PLAN.md boundary rules and validates them against the actual import graph. If a frontend module starts importing from the database layer, it's caught here before merge.
