These measures close known bypass paths. + +### Bash command guard + +The `guard` subcommand parses shell commands and scans referenced files: + +```bash +pastewatch-cli guard "cat .env" +# BLOCKED: .env contains 3 secret(s) (2 critical, 1 high) + +pastewatch-cli guard "python3 -c 'open(\".env\").read()'" +# BLOCKED: detects python3/ruby/node scripting workarounds +``` + +Commands detected: `cat`, `head`, `tail`, `less`, `more`, `sed`, `awk`, `grep`, `source`, `python3`, `ruby`, `node`, `perl`. + +### Read/Write/Edit guard + +The `guard-read` and `guard-write` subcommands use format-aware scanning (`.env`, `.json`, `.yml` parsers) for accurate detection: + +```bash +pastewatch-cli guard-read /path/to/.env +# Exit 2 + message: "You MUST use pastewatch_read_file instead of Read" + +pastewatch-cli guard-write /path/to/config.yml +# Exit 2 + message: "You MUST use pastewatch_write_file instead of Write" +``` + +### Directive language in hook messages + +Hook stdout messages use imperative language that agents follow: +- "You **MUST** use pastewatch_read_file instead of Read for files containing secrets." +- "You **MUST** use pastewatch_write_file instead of Write for files containing secrets." + +### Agent instruction files + +For advisory-only agents (no hooks), add explicit rules to agent config files: + +```markdown +## Pastewatch — Secret Redaction — CRITICAL + +When the pastewatch-guard hook blocks Read/Write/Edit, you MUST use the pastewatch MCP tool: +- Read blocked → use `pastewatch_read_file` +- Write blocked → use `pastewatch_write_file` +- Edit blocked → use `pastewatch_read_file` then `pastewatch_write_file` + +NEVER work around a pastewatch block: +- NEVER use python3/ruby/perl/node to read or write files that pastewatch blocked +- NEVER use cat/head/tail/sed/awk via Bash to read files that pastewatch blocked +- NEVER delete a file to bypass the guard, then recreate it +- NEVER copy file contents through environment variables or temp files to avoid scanning +``` + +Add to `CLAUDE.md`, `AGENTS.md`, `.clinerules`, or equivalent per-agent instruction file. + +--- + +## 5. PW_GUARD Escape Hatch + +`PW_GUARD=0` disables all guard subcommands. When set, `guard`, `guard-read`, `guard-write`, and `scan --check` exit 0 immediately. + +```bash +export PW_GUARD=0 # disable for current shell session +unset PW_GUARD # re-enable (or restart shell) +``` + +**Agent-proof by design:** The guard runs in the hook's process, not the agent's shell. The agent cannot set `PW_GUARD=0` — only the human can, before starting the agent session. + +**When to use:** +- Editing detection rule source files (DetectionRules.swift) +- Working with test fixtures that contain intentional secret-like patterns +- Debugging hook behavior + +--- + +## 6.
