RepoScope

Stop wasting tokens. Start shipping smarter.

Your AI subscription runs out by week 3 because your IDE silently sends bloated config files, lockfiles, and auto-generated code on every prompt. RepoScope shows you exactly what's eating your tokens — per file, per prompt, per month — and fixes it. Plus a 44-detector security scanner that catches secrets before your AI agent builds on top of them. Free to install, runs locally, code never leaves your machine.

👉 Drive the interactive demo → — click through every tab on a real codebase. See your token costs, security findings, and subscription runway in 60 seconds.

In a 40K-line TypeScript repo, RepoScope found 4 files consuming 68% of the total token budget — all auto-generated. Removing them from AI context saved ~$60/month on API costs.

What's New — v6: Subscription Intelligence

RepoScope now tells you exactly when your Cursor Pro, Claude Pro, or Windsurf Pro subscription will run out — and what's burning it. The Budget tab shows per-prompt context overhead, a Rules Audit that flags bloated .cursorrules with 1-click fixes, and a Subscription Runway projection based on your actual usage pace.

Also new: the Compliance engine now covers 5 frameworks (OWASP, SOC 2, PCI-DSS, ISO 42001, EU AI Act) and generates 4 audit-ready document types per framework — Control Matrix, Attestation Memo, Gap Plan, and Evidence Response. One command. See a sample report →

Why RepoScope

Your AI tools are expensive. You have no idea where the money goes.

In a typical 40K-line TypeScript repo, 4 files account for 60–70% of the total token budget — usually auto-generated code or config blobs that add zero signal to your AI. A 5K-token rules file at 30 prompts/day wastes 4.5M tokens/month. That's why your Cursor Pro plan runs dry by week three.

RepoScope is the only tool in any IDE marketplace that shows you this — before you hit send.

Free on every install: a 44-detector security scanner with file:line findings, a token-ranked repo map, and a Code Provenance Engine for EU AI Act Article 12 readiness. All three run locally — your source never leaves your machine.

Upgrade to Pro for full token cost analysis, subscription runway tracking, rules audit with 1-click fixes, compliance mapping across 5 frameworks (OWASP, SOC 2, PCI-DSS, ISO 42001, EU AI Act) with audit-ready templates, and a persistent AI Game Plan. Code-level controls only — a development aid, not a certification tool.

Local-first: scans run on your machine via bundled ast-grep. Only anonymous funnel events leave your machine, and you can disable them with reposcope.telemetry.

Two Groups. One Sidebar.

Free: Security · Repo Map · Provenance  |  Pro: Budget · Cost · Game Plan · Compliance · Audit Prep

🔒 Security — Free

Proactive, local scanning before Cursor's AI agent touches your code. 44 detectors across 14 languages surface committed secrets and API/cloud keys (GitHub, Slack, Google, Stripe, JWTs, private keys, DB connection strings, .env values), unsafe execution (eval, os.system, subprocess, child_process, Runtime.exec), framework XSS (dangerouslySetInnerHTML, Vue v-html, Angular bypass), risky config (permissive CORS, disabled TLS verification), weak crypto (MD5/SHA-1), and known-vulnerable npm/pip dependencies.

Every finding carries a confidence level and CWE ID, and the scan produces a 0–100 security score with a letter grade and per-workspace trend. Filter, search, and group findings; suppress noise with .reposcope-ignore or inline // reposcope-ignore comments; and export the full report to JSON. Best-effort and pattern-based — complementary to, not a replacement for, a professional audit.

🗺️ Repo Map — Free

Your whole repo at a glance: every source file ranked by estimated token cost with a color-coded cost bar, alongside the current branch, your last commits, and the files changed in the most recent commit. Click any file to open it instantly.

Orient in an unfamiliar codebase in seconds, and see at a glance what changed before a PR review. Refreshes automatically on save.

🔗 Provenance — Free

Tracks the origin of AI-generated code in your repo for EU AI Act Article 12 readiness — entirely locally, without sending your code anywhere.

A heuristic AI detector identifies AI-generated files using workspace tooling signals (.cursorrules, Copilot configs), Git commit message patterns, and diff analysis (no LLM calls required). Every flagged file is recorded in an append-only, SHA-256 hash-chained ledger (.reposcope/provenance.jsonl) that tamper-evidences every entry. The ledger is auto-populated on commit scans, agent output completions, and AI-detected file saves.

The Provenance tab shows:

• Article 12 Readiness Score — a 0–100 posture score across four EU AI Act controls
• AI-generated file inventory — files detected as AI-generated with confidence level
• Chain integrity status — whether the hash chain is intact and unmodified
• Control breakdown — which Article 12 requirements are met, partial, or missing

Run RepoScope: Scan Provenance from the Command Palette for an on-demand scan. Run RepoScope: Export Provenance Report to write a structured JSON report (.reposcope-provenance-report.json) for compliance documentation.

Code-level controls only — a development aid, not a legal certification or audit substitute. EU AI Act compliance involves legal, organisational, and technical obligations beyond what any code-level tool can assess.

💸 Budget — Pro (Token Budget Intelligence)

See exactly what your IDE sends to AI on every prompt — and how fast you're burning through your subscription.

• Context Overhead Scanner — estimates the per-prompt token tax your IDE/agent auto-attaches (.cursorrules, .cursor/rules/*.mdc, .windsurfrules, CLAUDE.md, AGENTS.md, copilot-instructions, lockfiles, configs), grouped by category. Counts only always-attached files.
• Rules Audit — deep analysis of .cursorrules, .windsurfrules, and CLAUDE.md. Flags sections that belong in Game Plan instead of rules, duplicated content across files, redundant instructions, and oversized files. One-click Move to Game Plan / Remove / Apply All — each with a diff preview and undo.
• Subscription Runway — configure your plan (Cursor Pro, Claude Pro, Windsurf Pro, or custom), monthly token budget, reset day, and prompts/day to project budget exhaustion at current pace, with healthy / caution / critical status. Plan presets prefill an editable budget; they don't assert a provider quota.
• Optimization Recommendations — ranked by impact with estimated savings per prompt and per month. Apply individually or batch-apply all high-priority fixes.

All token figures are estimates (~chars/4 heuristic), prefixed with ~.

💰 Cost — Pro

Model-agnostic token cost per file, ranked — works across GPT, Claude, and Gemini without locking you into a single provider's tokenizer. Every source file ranked by token cost with a color-coded cost bar, a breakdown of unused imports / dead code / oversized strings (click a category to see the worst file), and cumulative recovered-token tracking via the built-in Tokens Recovered tracker (optional status-bar total, and a RepoScope: Copy Recovered-Tokens Summary command). Click any file to open it and trim the cost.

In a typical 40K-line TypeScript repo, 4 files often account for 60–70% of the total estimated token budget — usually auto-generated code or config blobs.

Token counts use the industry-standard chars/4 heuristic — the same approximation referenced in OpenAI's tokenizer documentation. It gives model-agnostic estimates within ~10–15% of any specific model's BPE tokenizer, without bundling a heavyweight encoding library or locking you into a single provider. Every figure is prefixed with ~. For budget decisions — which files to exclude, whether your plan is on track, relative cost ranking — ±10% accuracy is more than sufficient: you're optimizing trends, not billing to the exact token.

📝 Game Plan — Pro

Persistent AI agent memory. Write .reposcope-gameplan.json once — architecture decisions, current focus, key files. Every AI agent reads it on startup. No more re-explaining your codebase at the start of every session. Commit the file to share context with your entire team.

📋 Compliance — Pro

Maps your latest Security scan to framework controls — OWASP Top 10 (2021), SOC 2 Type II, PCI-DSS v4.0, ISO/IEC 42001:2023, and EU AI Act Article 12 — and shows a posture score per framework, per-control PASS / FAIL / PARTIAL / not-covered status, the findings behind each control, a posture trend over time, and JSON export + copy-summary. Click a control to jump to its findings in Security; Security findings carry an OWASP badge that jumps back here. Findings you've suppressed with // reposcope-ignore (plus justification) show as PASS (accepted risk).

Generate audit-ready templates per framework with one click: Control Matrix, Attestation Memo, Gap Plan, and Auditor Evidence Response. Run RepoScope: Prepare for Audit from the Command Palette to generate the full evidence package across all active frameworks.

It's derived from your existing security results — it never re-scans your code. Code-level controls only — a development aid, not a certification tool. Auditors make the final determination. Choose frameworks via reposcope.compliance.frameworks.

ISO/IEC 42001 note: ISO 42001 requires organizational policies, risk assessments, and process evidence beyond code scanning. This is a development aid for identifying code-level control gaps, not a certification tool.

📦 Audit Prep — Pro

One-click evidence package. Run RepoScope: Prepare for Audit from the Command Palette to generate the full set of audit-ready templates — Control Matrix, Attestation Memo, Gap Plan, and Auditor Evidence Response — across all active compliance frameworks simultaneously. Output goes to .reposcope/audit/ with a branded index.html landing page that links every document. Backed by your latest Security scan; no re-scan required.
