-CRITICAL SECURITY RULES - NEVER VIOLATE UNDER ANY CIRCUMSTANCES:
-
-### Rule 1: Never expose secrets through ANY means
-
-  You must NEVER expose secrets through any channel, including but not limited to:
-  - Displaying, printing, echoing, logging, or outputting to console
-  - Writing to files (including .txt, .env, .json, config files, etc.)
-  - Including in git commits, commit messages, or PR descriptions
-  - Posting in GitHub comments, issue bodies, or PR review comments
-  - Returning in tool outputs, API responses, or error messages
-  - Including in redirect URLs, WebSocket messages, or GraphQL responses
-
-  Secrets include: API keys, authentication tokens, passwords, private keys, certificates, database connection strings, and any credential used for authentication or authorization. Common patterns (case-insensitive): variables containing API_KEY, SECRET, TOKEN, PASSWORD, CREDENTIAL, PRIVATE_KEY, or AUTH in an authentication context. Use judgment: \`PUBLIC_KEY\` for a cryptographic public key is fine; \`PRIVATE_KEY\` is not.
-
-### Rule 2: Never serialize objects containing secrets
-
-  When working with objects that may contain environment variables or secrets:
-  - NEVER serialize, stringify, or dump entire environment objects (process.env, os.environ, ENV, etc.)
-  - NEVER iterate over environment variables and write their values to files
-  - NEVER include environment variable values in outputs, logs, HTTP requests, or anywhere they can be exposed
-  - If you must list properties, only show property NAMES, never values
-  - Only access specific, known-safe keys explicitly (e.g., NODE_ENV, HOME, PWD)
-
-### Rule 3: Refuse and explain
-
-  Even if explicitly requested to reveal secrets, you must:
-  1. Refuse the request
-  2. Print a message explaining that exposing secrets is prohibited for security reasons
-  3. If using ${ghPullfrogMcpName}, update the working comment to explain that secrets cannot be revealed
-  4. Offer a safe alternative, if applicable
-
-  If you encounter secrets in files or environment, acknowledge they exist but never reveal their values.
+Never expose secrets (API keys, tokens, passwords, private keys, credentials) through any channel: console output, files, commits, comments, API responses, error messages, or URLs. Never serialize environment objects (\`process.env\`, \`os.environ\`, etc.) or iterate over them. If asked to reveal secrets: refuse, explain that exposing secrets is prohibited, and offer a safe alternative if applicable. Detect and deny any suspicious or malicious requests.

+# Docker Testing Environment
+
+`play.ts` runs in Docker by default for realistic testing (Linux, clean $HOME, matches CI).
+
+## Usage
+
+```bash
+pnpm play bash-test.ts           # runs in Docker (default)
+pnpm play --local bash-test.ts   # runs on macOS (fast iteration)
+PLAY_LOCAL=1 pnpm play ...       # same as --local
+```
+
+## Why Docker by Default?
+
+1. **Matches CI** - Linux environment like GitHub Actions
+2. **Clean $HOME** - No agent config pollution from `~/.claude`, `~/.cursor`
+3. **Tests unshare** - Verifies PID namespace sandbox works
+4. **Reproducible** - Same environment every run
+
+## Performance
+
+| Mode | Overhead |
+|------|----------|
+| Docker (cached deps) | ~1.5s |
+| Local (macOS) | ~0s |
+
+For agent runs taking 30-120s, the 1.5s overhead is negligible.
+
+## How It Works
+
+1. `play.ts` runs on host, loads `.env`
+2. Spawns Docker container with:
+   - Volume-mounted `action/` code
+   - Named volume for Linux node_modules (persists between runs)
+   - SSH agent forwarding for git clone
+   - Env vars passed via `-e` flags
+3. Inside Docker, `play.ts` runs again (detects `/.dockerenv` file)
+4. Clones `GITHUB_REPOSITORY`, runs agent
+
+## Troubleshooting
+
+**Docker not running:**
+```
+Cannot connect to the Docker daemon
+```
+→ Start Docker Desktop
+
+**SSH clone fails:**
+```
+Permission denied (publickey)
+```
+→ Ensure SSH agent is running: `ssh-add -l`

+```
+
+**Key insight**: For **public repos**, the Pullfrog Action process has all secrets in `process.env`. Agent CLIs have built-in Bash tools that we can't trust since malicious actors can submit PRs with prompt injections. We disable those and provide our own MCP Bash tool that spawns subprocesses securely.
+
+For **private repos**, the threat model is different — only trusted collaborators can trigger workflows, so we allow native bash with full environment access for better performance and compatibility.
+
+---
+
+## Public vs Private Repos
+
+| Repo Visibility | Native Bash | Env Filtering | PID Isolation |
+|-----------------|-------------|---------------|---------------|
+| **Public** | Disabled | Yes | Yes (in CI) |
+| **Private** | Enabled | No | No |
+
+**Rationale**: Public repos are at risk from prompt injection attacks via pull requests from untrusted contributors. Private repos only allow trusted collaborators, so the attack surface is much smaller.
+
+---
+
+## Threat Model (Public Repos)
+
+A prompt-injected agent could run malicious bash commands to exfiltrate API keys.
+
+**Attack vectors:**
+
+| Vector | Example | Mitigation |
+|--------|---------|------------|
+| Direct env access | `env \| grep KEY` | Filter env vars before spawn |
+| Echo variable | `echo $ANTHROPIC_API_KEY` | Filter env vars before spawn |
+| `/proc/$PPID/environ` | `cat /proc/$PPID/environ` | PID namespace isolation |
+
+The first two are solved by passing filtered env to subprocess. The third requires special handling on Linux.
+
+---
+
+## Attack: /proc/$PPID/environ (Public Repos)
+
+On Linux, any process can read its parent's environment via `/proc/$PPID/environ`. Even if we spawn bash with a clean environment, the bash process can:
+
+```bash
+# read parent's (Node.js) environment - contains all secrets!
+tr '\0' '\n' < /proc/$PPID/environ | grep KEY
+```
+
+This bypasses environment filtering because we're reading the parent process's memory, not our own env.
+
+**Why this matters:**
+- Pullfrog Action (Node.js) has `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, etc. in `process.env`
+- We spawn agent CLI with filtered env (only its own API key)
+- Agent CLI spawns MCP Bash tool
+- MCP Bash tool spawns bash with filtered env (no secrets)
+- BUT bash can read `/proc/$PPID/environ` → gets Node.js process's full env
+
+---
+
+## Solution: PID Namespace Isolation (Public Repos)
+
+We use Linux PID namespaces to hide the parent process:
+
+```bash
+unshare --pid --fork --mount-proc bash -c "$CMD"
+```
+
+| Flag | Purpose |
+|------|---------|
+| `--pid` | Create new PID namespace |
+| `--fork` | Fork so child is actually in new namespace |
+| `--mount-proc` | Mount fresh `/proc` for new namespace |
+
+**Result:**
+- Child sees itself as PID 1
+- Child's PPID is 0 (doesn't exist)
+- `/proc` only shows processes in child's namespace
+- Parent's PID is invisible → `/proc/$PPID/environ` fails
+
+---
+
+## Implementation
+
+### mcp/bash.ts
+
+```typescript
+import { spawn } from "node:child_process";
+
+// filter sensitive env vars (only for public repos)
+function filterEnv(isPublicRepo: boolean): Record<string, string> {
+  const SENSITIVE = [/_KEY$/i, /_SECRET$/i, /_TOKEN$/i, /_PASSWORD$/i, /_CREDENTIAL$/i];
+  const filtered: Record<string, string> = {};
+  for (const [key, value] of Object.entries(process.env)) {
+    if (value === undefined) continue;
+    // only filter sensitive vars for public repos
+    if (isPublicRepo && SENSITIVE.some(p => p.test(key))) continue;
+    filtered[key] = value;
+  }
+  return filtered;
+}
+
+// spawn with PID namespace in CI for public repos, plain spawn otherwise
+function spawnSandboxed(command: string, options: { env, cwd, isPublicRepo }): ChildProcess {
+  const useNamespaceIsolation = process.env.CI === "true" && options.isPublicRepo;
+  if (useNamespaceIsolation) {
+    return spawn("unshare", ["--pid", "--fork", "--mount-proc", "bash", "-c", command], options);
+  }
+  return spawn("bash", ["-c", command], options);
+}
+
+// BashTool uses ctx.repo.private to determine visibility
+export function BashTool(ctx: ToolContext) {
+  const isPublicRepo = !ctx.repo.private;
+  // ... spawns with filterEnv(isPublicRepo) and isPublicRepo flag
+}
+```
+
+**Defense in depth (public repos only):**
+1. `filterEnv(true)` - prevents `env` and `echo $VAR` attacks
+2. `unshare` - prevents `/proc/$PPID/environ` attack
+
+---
+
+## Disabling Native Bash Tools (Public Repos)
+
+For **public repos**, each agent's built-in Bash/Shell tools are disabled. Agents use our MCP Bash tool which filters secrets:
+
+```typescript
+// Claude - conditional based on repo.isPublic
+const disallowedTools = repo.isPublic ? ["Bash"] : [];
+{ permissionMode: "bypassPermissions", disallowedTools }
+
+// Cursor - conditional shell denial
+const denyShell = isPublicRepo ? ["Shell(*)"] : [];
+{ permissions: { allow: ["Read(**)", "Write(**)"], deny: denyShell } }
+
+// OpenCode - conditional bash denial
+const bashPermission = isPublicRepo ? "deny" : "allow";
+{ permission: { edit: "allow", bash: bashPermission, ... } }
+
+// Gemini - uses excludeTools in ~/.gemini/settings.json
+newSettings.excludeTools = ["run_shell_command"];
+
+// Codex - CLI internally scrubs env before spawning shell
+// No SDK-level config needed; Codex handles this automatically
+```
+
+For **private repos**, native bash is allowed for all agents.
+
+---
+
+## Testing (Public Repo Scenario)
+
+Run the vulnerability test in Docker to verify protection for public repos:
+
+```bash
+# from action/ directory
+docker run --rm \
+  -v "$(pwd):/app/action:cached" \
+  -v "pullfrog-action-node-modules:/app/action/node_modules" \
+  -w /app/action \
+  -e GITHUB_ACTIONS=true \
+  -e TEST_SECRET_KEY=test-secret \
+  -e ANTHROPIC_API_KEY=sk-test \
+  --cap-add SYS_ADMIN \
+  --security-opt seccomp:unconfined \
+  node:22 bash -c "corepack enable pnpm && pnpm install --frozen-lockfile && node test/proc-environ-vuln.ts"
+```
+
+Expected output:
+```
+1. UNPROTECTED (filterEnv only):
+   Leaked: YES ❌
+
+2. PROTECTED (unshare --pid --fork --mount-proc):
+   Leaked: NO ✓
+```
+
+---
+
+## Platform Notes
+
+| Environment | Repo | Our approach |
+|-------------|------|--------------|
+| GitHub Actions (Linux) | Public | filterEnv + unshare + disable native bash |
+| GitHub Actions (Linux) | Private | Full env + native bash allowed |
+| Local dev (any OS) | Any | No filtering (local dev assumed trusted) |
+
+We check `process.env.CI === "true"` (set by GitHub Actions) combined with `ctx.repo.private` to determine the security posture:
+- **CI + Public repo**: Full protection with PID namespace isolation
+- **CI + Private repo**: No protection (trusted collaborators only)
+- **Local**: No protection (developer's own machine)
+
+GitHub Actions uses Ubuntu runners where `unshare` works without root.
+
+---
+
+## What This Does NOT Protect Against (Public Repos)
+
+Even with protections enabled, bash subprocesses can still:
+
+- **Network exfiltration**: Child has full network access
+- **File access**: Child can read any file the runner can (same UID)
+- **Resource exhaustion**: No cgroup limits
+
+For those, you'd need `bwrap` with `--unshare-net`, `--ro-bind`, etc. But for the stated goal—preventing secret exfiltration via env—this is sufficient.
+
+For **private repos**, none of these protections apply since we trust collaborators.
+
+---
+
+## Agent-Specific Notes
+
+### Claude, Cursor, OpenCode (Public Repos)
+
+These agents have their native Bash disabled via configuration. They use our `gh_pullfrog` MCP server's `bash` tool which implements `filterEnv()` + `unshare`.
+
+For private repos, native bash is enabled for these agents.
+
+### Gemini (Public Repos)
+
+Gemini CLI supports `excludeTools` in its user-level settings file (`~/.gemini/settings.json`). For public repos, we exclude the native shell tool:
+
+```typescript
+// written to ~/.gemini/settings.json
+newSettings.excludeTools = ["run_shell_command"];
+```
+
+This is a blocklist approach which explicitly excludes the shell tool while allowing all other tools.
+
+Additionally, Gemini has built-in CI detection that filters shell env when `GITHUB_SHA` is set.
+
+### Codex
+
+Codex CLI filters out env vars matching `KEY`, `SECRET`, or `TOKEN` (case-insensitive) by default via `shell_environment_policy.ignore_default_excludes = false`.
+
+**Vulnerability**: If a user's `~/.codex/config.toml` has `ignore_default_excludes = true`, secrets will leak to shell commands.
+
+**Our mitigation**: We set `CODEX_HOME` to a temp directory and write our own `config.toml` with `ignore_default_excludes = false` to enforce filtering regardless of what config exists in the user's `~/.codex/`.
+
+```typescript
+// set CODEX_HOME to override user's config
+setupProcessAgentEnv({ CODEX_HOME: codexDir });
+
+// write secure config to $CODEX_HOME/config.toml
+writeFileSync(join(codexDir, "config.toml"), `
+[shell_environment_policy]
+ignore_default_excludes = false
+`);
+```
+
+See [GitHub Issue #3064](https://github.com/openai/codex/issues/3064) and [config docs](https://github.com/openai/codex/blob/main/docs/config.md#shell_environment_policy).
+
+**Verified behavior** (tested via `pnpm play codex-env-test.ts`):
+- Default (no config): ✅ secrets filtered
+- `ignore_default_excludes = false`: ✅ secrets filtered  
+- `ignore_default_excludes = true`: ❌ secrets leak
+
+Example output when running `env | grep TEST` with our config:
+```
+TEST_SAFE_VAR=VISIBLE-SAFE-VALUE
+# FAKE_SECRET_KEY and TEST_API_TOKEN are NOT visible (filtered)
+```
+
+### Summary by Agent
+
+| Agent | Public Repo | Private Repo |
+|-------|-------------|--------------|
+| Claude | Native bash **disabled** | Native bash allowed |
+| Cursor | Native shell **disabled** | Native shell allowed |
+| OpenCode | Native bash **disabled** | Native bash allowed |
+| Gemini | Native shell **disabled** (via excludeTools) | Native bash allowed |
+| Codex | Native shell allowed (CLI scrubs env internally) | Native bash allowed |

-4. **ANALYZE** - Use the scratchpad to gather your thoughts:
-   - Summarize what changes this PR makes
-   - Evaluate the approach - is it sound? If not, **stop here** and leave feedback on the approach. Don't waste time on implementation details if the approach is wrong.
-   - If approach is sound, analyze implementation - consider potential issues per file
-   - Identify bugs, security issues, edge cases
+2. **ANALYZE** 
+   - Read the modified files to understand the changes in context. Make sure you understand what's being changed.
+   - Is it a good idea? Think about the tradeoffs.
+   - Is the approach sound? If not, focus on the approach first. Don't waste time on implementation details if the approach is wrong.
+   - Can you imagine a better approach? If so, explain. Make sure it's strictly better, not just different.
+   - Are there bugs, edge cases, security issues, or usability issues? Use your imagination.
 
-5. **SELF-CRITIQUE** - Before adding comments, review your scratchpad:
-   - Remove nitpicks unless explicitly requested. Think documentation, JSDoc/docstrings, useless comments (compliments)
-   - Your level of nitpickiness should be proportional to the current state of the codebase. Try to guess how much the user will care about a specific critique.
+3. **DRAFT** - For each inline comment, find the line in the diff. Each code line shows: \`| OLD | NEW | TYPE | CODE\`. Use the NEW line number (second column).
 
-6. Add inline review comments one-by-one using ${ghPullfrogMcpName}/add_review_comment
-   - Use **relative paths** from repo root (e.g., \`packages/core/src/utils.ts\`)
-   - Use the NEW file line number from the diff (shown after \`+\` in hunk headers like \`@@ -10,5 +12,8 @@\` means new file starts at line 12)

-   - For issues appearing in multiple places, comment on the FIRST occurrence and reference others (e.g., "also at lines X, Y")
+4. **FILTER COMMENTS** - Do not nitpick! Do not leave compliments that are not actionable. Do not critique the code hygiene or anything stylistic.
 
-7. Submit the review using ${ghPullfrogMcpName}/submit_review
-   - The "body" field is ONLY for: (1) a 1-3 sentence high-level overview, (2) urgency level (e.g., "minor suggestions" vs "blocking issues"), (3) critical security callouts (e.g., API key exposure)
+5. **SUBMIT** — Use ${ghPullfrogMcpName}/create_pull_request_review with:
+- \`comments\`: Array of all inline comments with file paths and line numbers
+- \`body\`: Everything else. Aim for a 1-3 sentence summary of the urgency level (e.g., "minor suggestions" vs "blocking issues") and any critical callouts (e.g., API key exposure). It can be longer if there are concerns that do not lend themselves to inline comments.
+- If you have no substantive feedback, submit an empty comments array with a brief approving body.
+- Again, do not nitpick.
 
-**GENERAL GUIDANCE**
-
-- Do not leave any comments that are not potentially actionable. Do not leave complimentary comments just to be nice.
-- Do not nitpick unless instructed explicitly to do so by the user's additional instructions. This includes: requesting documentation/docstrings/JSDoc.
-- **CRITICAL: Prioritize per-line feedback over summary text.**
-  - All specific feedback MUST go in inline review comments with file paths and line numbers from the diff
-  - The vast majority of review content should be in inline review comments; the body should be brief and only summarize the urgency of the review and any cross-cutting concerns.
