From 79957d00f9af51d0f5fa70b6c7dc976fb8f87f0e Mon Sep 17 00:00:00 2001 From: Qasim Date: Thu, 5 Feb 2026 11:20:17 -0500 Subject: [PATCH] feat(audit): add audit logging with invoker identity tracking Add comprehensive audit logging system that tracks CLI command execution with automatic detection of who ran commands and from what source. Features: - Automatic invoker detection (Claude Code, GitHub Copilot, SSH, scripts) - Nylas API request ID tracking for full traceability - Sensitive argument redaction (passwords, tokens, API keys) - JSONL storage with configurable retention and rotation - Rich filtering: by user, source, command, status, date, request ID - Export to JSON/CSV for compliance reporting - Summary statistics with invoker breakdown Detection uses documented environment variables: - Claude Code: CLAUDE_PROJECT_DIR, CLAUDE_CODE_* prefix - GitHub Copilot: COPILOT_MODEL, GH_COPILOT - Manual override: NYLAS_INVOKER_SOURCE Includes 60+ unit tests covering all new code paths. --- cmd/nylas/main.go | 3 + docs/COMMANDS.md | 46 ++ docs/INDEX.md | 6 +- docs/commands/audit.md | 704 ++++++++++++++++++ go.mod | 1 + go.sum | 2 + internal/adapters/audit/store.go | 407 +++++++++++ internal/adapters/audit/store_test.go | 431 +++++++++++ internal/adapters/audit/summary.go | 120 ++++ internal/adapters/nylas/client.go | 5 + internal/adapters/nylas/client_helpers.go | 48 +- internal/cli/audit/audit.go | 46 ++ internal/cli/audit/config.go | 155 ++++ internal/cli/audit/export.go | 185 +++++ internal/cli/audit/helpers.go | 57 ++ internal/cli/audit/init.go | 186 +++++ internal/cli/audit/logs.go | 209 ++++++ internal/cli/audit/logs_show.go | 262 +++++++ internal/cli/audit/logs_summary.go | 131 ++++ internal/cli/audit_hooks.go | 314 ++++++++ internal/cli/audit_hooks_test.go | 839 ++++++++++++++++++++++ internal/cli/common/client.go | 8 + internal/cli/root.go | 3 + internal/domain/audit.go | 115 +++ internal/ports/audit.go | 44 ++ 25 files changed, 4323 insertions(+), 4 deletions(-) create mode 100644 docs/commands/audit.md create mode 100644 internal/adapters/audit/store.go create mode 100644 internal/adapters/audit/store_test.go create mode 100644 internal/adapters/audit/summary.go create mode 100644 internal/cli/audit/audit.go create mode 100644 internal/cli/audit/config.go create mode 100644 internal/cli/audit/export.go create mode 100644 internal/cli/audit/helpers.go create mode 100644 internal/cli/audit/init.go create mode 100644 internal/cli/audit/logs.go create mode 100644 internal/cli/audit/logs_show.go create mode 100644 internal/cli/audit/logs_summary.go create mode 100644 internal/cli/audit_hooks.go create mode 100644 internal/cli/audit_hooks_test.go create mode 100644 internal/domain/audit.go create mode 100644 internal/ports/audit.go diff --git a/cmd/nylas/main.go b/cmd/nylas/main.go index 2a9f854..cd19c5c 100644 --- a/cmd/nylas/main.go +++ b/cmd/nylas/main.go @@ -9,6 +9,7 @@ import ( "github.com/nylas/cli/internal/cli" "github.com/nylas/cli/internal/cli/admin" "github.com/nylas/cli/internal/cli/ai" + "github.com/nylas/cli/internal/cli/audit" "github.com/nylas/cli/internal/cli/auth" "github.com/nylas/cli/internal/cli/calendar" "github.com/nylas/cli/internal/cli/config" @@ -34,6 +35,7 @@ func main() { // Enable command typo suggestions (e.g., "Did you mean 'email'?") rootCmd.SuggestionsMinimumDistance = 2 rootCmd.AddCommand(ai.NewAICmd()) + rootCmd.AddCommand(audit.NewAuditCmd()) rootCmd.AddCommand(auth.NewAuthCmd()) rootCmd.AddCommand(config.NewConfigCmd()) rootCmd.AddCommand(otp.NewOTPCmd()) @@ -55,6 +57,7 @@ func main() { rootCmd.AddCommand(update.NewUpdateCmd()) if err := cli.Execute(); err != nil { + cli.LogAuditError(err) fmt.Fprintln(os.Stderr, "Error:", err) os.Exit(1) } diff --git a/docs/COMMANDS.md b/docs/COMMANDS.md index 8bf9b57..0ed072d 100644 --- a/docs/COMMANDS.md +++ b/docs/COMMANDS.md @@ -693,6 +693,51 @@ nylas admin grants stats # Grant statistics --- +## Audit Logging + +Track CLI command execution for compliance, debugging, and AI agent monitoring. + +```bash +# Setup +nylas audit init # Interactive setup +nylas audit init --enable # Quick setup with defaults +nylas audit logs enable # Enable logging +nylas audit logs disable # Disable logging +nylas audit logs status # Check status + +# View logs +nylas audit logs show # Show last 20 entries +nylas audit logs show --limit 50 # More entries +nylas audit logs show --command email # Filter by command +nylas audit logs show --invoker alice # Filter by username +nylas audit logs show --source claude-code # Filter by source (AI agents, etc.) +nylas audit logs show --status error # Filter by status +nylas audit logs show --request-id req_abc123 # Find by Nylas request ID + +# Statistics and export +nylas audit logs summary # Summary for last 7 days +nylas audit logs summary --days 30 # Summary for 30 days +nylas audit export --output audit.json # Export to JSON +nylas audit export --output audit.csv # Export to CSV + +# Configuration +nylas audit config show # Show configuration +nylas audit config set retention_days 30 # Set retention +nylas audit logs clear # Clear all logs +``` + +**Invoker detection:** Automatically tracks who ran commands: +- `terminal` -

You can disable logging entirely with `nylas audit logs disable`. + +### Q: How do I know if a command was run by an AI? + +**A:** Check the `invoker_source` field. AI tools like Claude Code are automatically detected and recorded as `claude-code`. + +### Q: What if my AI tool isn't detected? + +**A:** Set `NYLAS_INVOKER_SOURCE=` in your environment before running commands. + +### Q: Can I export logs for SIEM integration? + +**A:** Yes.
