AI Agent File Guard CLI
Build a cross-agent security wrapper that enforces path restrictions, secret redaction, and network egress controls for coding agents. The strongest appeal is to developers already using AI coding tools who want immediate protection without re-architecting their machines or fully trusting vendor promises.
Pourquoi c'est important
You want the speed of AI-assisted coding, but every session feels like a tradeoff between productivity and exposure. Your repo may include keys, customer data samples, finance docs, or deployment files that should never leave the machine. Existing advice tells you to change permissions, run containers, or create a separate user, but that is brittle and easy to misconfigure. Even worse, the agent may treat denied access as a puzzle and try indirect routes through search commands, build tools, logs, or history. What you need is a guardrail layer that works with the agent you already use, blocks risky access by default, and gives you proof that sensitive material stayed protected.
- · Conçu pour Individual developers, small teams, and security-conscious engineering orgs using AI coding agents on local repositories and remote dev environments..
- · Monétisation la plus probable : SaaS subscription with CLI and team dashboard.

- Package installers for macOS and Linux with one-command onboarding
- Run closed beta with 10 developers and collect blocked-action telemetry
Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1The product may not achieve enough real security coverage because agents can leak data through too many indirect channels outside the wrapper.
- 2Developers may decide OS permissions and containers are good enough, especially if vendor docs improve and free recipes spread.
- 3Model vendors may release native path exclusion, sandbox, and policy controls that satisfy most of the market before this product gains traction.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
The discussion repeatedly returned to one theme: developers want a safer way to use coding agents around sensitive files, but current methods are manual and incomplete. Roughly a dozen comments focused on file permissions, containers, secret handling, or the risk of accidental upload through normal commands. Several participants also emphasized that agent behavior is not deterministic, making simple ignore semantics insufficient without runtime enforcement.
