From 4b475ff78697046c438d83e2c406e9e77bbf9a2b Mon Sep 17 00:00:00 2001 From: priyamkarn Date: Sat, 11 Jul 2026 04:53:01 +0530 Subject: [PATCH 1/3] Redact secret-shaped strings from transcript bundles before writing to disk sanitizeTranscriptMessage previously only stripped fake / tags (prompt-injection defense) with zero redaction of API keys, tokens, passwords, or .env content. Adds pattern-based redaction for common secret shapes (AWS, GitHub, Slack, Stripe, Anthropic, OpenAI, Google keys, JWTs, Bearer tokens, private key blocks, .env assignments) at the single choke point every platform adapter calls. CLI now warns with a redaction count when writing a transcript bundle. --- apps/cli/main.ts | 10 ++ libs/session-transcript/bundle.ts | 30 ++++ libs/session-transcript/markdown.ts | 24 ++- libs/session-transcript/redact.ts | 125 +++++++++++++ package.json | 3 +- scripts/check-secret-redaction.js | 178 +++++++++++++++++++ scripts/check-transcript-bundle-redaction.js | 70 ++++++++ 7 files changed, 438 insertions(+), 2 deletions(-) create mode 100644 libs/session-transcript/redact.ts create mode 100644 scripts/check-secret-redaction.js create mode 100644 scripts/check-transcript-bundle-redaction.js diff --git a/apps/cli/main.ts b/apps/cli/main.ts index d6c0f42..b77942c 100644 --- a/apps/cli/main.ts +++ b/apps/cli/main.ts @@ -468,6 +468,16 @@ function runTranscriptBundle(args: string[]): void { for (const entry of result.entries) { console.log(`- ${entry.sessionRef ??
