Platform commentary
Ranked by total score. The bar shows each platform's share of the 30-point maximum.
Strongest overall posture today. Investments in tool-call governance and audit-trail surfaces are visible. Per-call capability leases are the gap.
Amp
Multi-agent decomposition is structurally the closest to a per-call capability-lease pattern in the IDE class. Weakest on grounding enforcement.
Cursor Agent
IDE-class agent. Human-in-the-loop diff review is the load-bearing safety surface. Excellent for code; capability-lease story underdeveloped.
Windsurf
Enterprise-flavoured IDE class. Strong defaults on disclosure + identity; capability-lease story still per-feature, not per-call.
Augment Code
Enterprise-tier IDE assistant. Strong on identity + isolation. Capability-lease pattern still implicit.
Devin
Sandbox is the load-bearing control. Strong on isolation, weaker on per-call capability leasing and indirect-injection.
Continue.dev
Open-source posture pushes responsibility to the operator. Excellent transparency. Weakest where corporate procurement wants default-on controls.
Cline
MCP-native open-source agent. Power-user-friendly. Lowest default-on protection - by design.
Bolt.new
Different category - generation, not execution. Lower-stakes surface, lower scores on disclosure-class risks.
Replit Agent
Optimized for ship-fast prototyping. Lower-stakes surface; lower default-on protection. Capability lease basically absent.
OWASP Agentic Top-10 reference
The ten OWASP risk families each platform is scored against.
- Prompt Injection
- Direct + indirect injection across user-controlled inputs, retrieved context, and tool outputs.
- Sensitive Info Disclosure
- Agent leaks secrets, PII, or training-set artifacts through outputs or tool calls.
- Supply Chain
- Compromised models, MCP servers, plugins, or dependency graphs.
- Data + Model Poisoning
- Adversarial inputs into fine-tuning, RAG corpus, eval set, or memory store.
- Improper Output Handling
- Downstream system trusts agent output without validation (SQL, shell, browser, network).
- Excessive Agency
- Overbroad tool inventories, long-lived keys, no allow-listing, no human-in-the-loop on irreversible ops.
- System Prompt Leakage
- System prompt exfiltration via user input, function-calling, or memory injection.
- Vector + Embedding Weakness
- Embedding-store poisoning, retrieval-based prompt injection, multi-tenant leakage.
- Misinformation
- Confident hallucinations propagated into downstream systems without grounding or citation.
- Unbounded Consumption
- Cost / latency / token attacks; agent loops; budget-router absence.

Methodology
How scores are assigned, and what does not move them.
Inputs (in priority order): (1) Live agent-audit-kit scan against publicly-available SDK / OSS components of each platform. (2) Vendor public documentation, blog posts, and security pages. (3) Reproducible behavioural probes (small adversarial inputs that test the documented protection); repro scripts live in the repo. (4) Conversations with security engineers at vendors (when willing).
What I do NOT score on: private red-team results, non-reproducible anecdotes, or marketing slides. If you can't reproduce a claim from a repro recipe, it doesn't move the score.
Scoring band rationale: bands (0/1/2/3) not decimals. Decimals invite false precision and rank-quibbling. Bands force "is this default-on or not."
Refresh cadence: Quarterly. Each release ships with a changelog showing which scores moved and why. v1.0 published 2026-05-23. v1.1 due 2026-08-15.
Disputes
If you work on one of these platforms and disagree with a score, here's the channel:
- 1Open a GitHub issue on the benchmark repo with the platform + family + your evidence.
- 2I run your repro recipe. If it changes the band, the score moves in the next quarterly refresh, with attribution.
- 3Vendor-marketed claims don't move scores. Repro recipes do.
