Setup

  1. 01

    Install and activate

    Download Silens, open it, and activate with the complete license key sent to your email. Reports and evidence stay in your local workspace.

  2. 02

    Connect your agent

    In Settings, choose the Codex and Claude Code home folders you use, then install the integrations. You can change this later.

  3. 03

    Start from confirmed evidence

    Invoke $silens in Codex or /silens in Claude Code after reproducing a finding. Review the draft and attachments in Silens before submitting anywhere.

Commands

$silens -h

List every Silens agent command without starting a report.

$silens

Create a report from confirmed evidence already in the conversation.

$silens HackerOne

Use the HackerOne format. You can name another available format or a saved program profile instead.

$silens --poc

If supported, a portable proof that makes triaging easier will be attached.

$silens --poc HackerOne

Combine a chosen format with the portable-proof request.

$silens update <report-id>

Propose an evidence change to an existing report. The current draft stays untouched until you accept it in Silens.

$silens update <report-id> --poc

If supported, this will attach a new portable proof without replacing the old one.

PoC Command

Optional, every time

Without --poc, Silens still writes evidence-backed reproduction steps and ordinary Proof of Concept text when appropriate. The flag simply asks for an additional portable artifact for the report.

Activation stays minimal

Only license, plan, version, and device-bound entitlement data is used to verify access.
