In a synchronized effort between human and AI, we tracked down and neutralized the gremlins in our Fly.io deployment! Our Journey: 1. 🛡️ Stability First: We armored our database connections with pre-ping and recycling to survive the remote environment's quirks. 2. 🔍 Logic Hunt: We spotted and fixed a sneaky NameError in the background initialization that was lying in wait. 3. 🚀 The Final Piece: We bridged the gap in 'forms.py', restoring the missing auth dependencies that caused the crash loop. This commit represents a milestone in our AI-Human orchestration—turning 500 errors into 200 successes. Ready for take-off! 🛫

Code Review
This pull request introduces several new Gemini CLI command definitions (gemini-invoke.toml, gemini-review.toml, gemini-scheduled-triage.toml, gemini-triage.toml) which outline detailed personas, security constraints, and execution workflows for AI agents performing tasks like CLI invocation, pull request reviews, and issue triaging. It also updates the .gitignore to exclude Gemini-related files. In the backend, logging has been enhanced in auth.py for demo user provisioning and in deployments.py for package validation and deployment deletion audit trails. The deployments.py file also removed the storage of runtime and version in deployment.schedule_config['mcp_config'], which a reviewer noted could be a regression impacting Fly.io deployments. The forms.py endpoint now requires authentication, and session.py was updated with database connection pooling settings for health and recycling. The package_validator.py now explicitly allows GitHub URLs for packages and uses a simpler check for dangerous characters instead of a strict regex, relying on create_subprocess_exec for shell injection prevention. On the frontend, new API routes (deployments/[id]/[action]/route.ts, deployments/[id]/route.ts) were added to proxy requests to the backend with authentication. The global-error.tsx file was removed. The sign-in flow was improved by allowing callbackUrl parameters for redirection after authentication, and the demo user ID was changed to a stable UUID in auth.ts. Frontend API calls (lib/api.ts) were updated to parse more detailed error messages from backend responses, and next.config.ts was configured to allow images from GitHub. A reviewer also suggested optimizing the toClientResponse function in the new frontend proxy routes to stream responses directly instead of buffering the entire body for potentially large responses.

The logic to store the detected runtime and version in the deployment.schedule_config has been removed. While the runtime variable is still used for the local subprocess fallback, it's no longer being passed to the FlyDeploymentService via the mcp_config. This seems like a regression and could cause Fly.io deployments to fail or use incorrect runtime settings, as this information is no longer persisted on the deployment record. Was the removal of these lines intentional? If FlyDeploymentService relies on runtime or version being in mcp_config, this change will break that functionality.

The toClientResponse helper function currently buffers the entire response from the backend by calling await response.text(). This can be inefficient, especially for potentially large responses. You can improve performance by streaming the response body directly to the client.
This same improvement can be applied to the toClientResponse function in frontend/app/api/deployments/[id]/route.ts as well.

// Pass the ReadableStream body directly to the NextResponse

The GitHub URL validation is too permissive. The check "github.com" in package.lower() will match any string containing "github.com", including potentially malicious inputs like "evil-package@github.com-fake.com" or even just a package named "my-github.com-wrapper". Consider using a more robust validation that checks for proper URL structure, such as parsing with urllib.parse.urlparse and verifying the hostname is exactly "github.com" or using a regex pattern that matches valid GitHub repository URLs (e.g., starting with "https://github.com/" or "git@github.com:").
| # Security: No regex needed here as we use create_subprocess_exec with a list | ||
| # of arguments in the runner, which prevents shell injection. | ||
| # We only perform a basic check to ensure no obviously dangerous characters | ||
| # are present if the user is using a custom runtime (future-proofing). | ||

The removal of the strict regex validation in favor of checking for shell metacharacters is less secure than the original approach. While the comment claims that create_subprocess_exec prevents shell injection, this change weakens the input validation defense-in-depth. The original regex ^(?:@[a-z0-9-*~][a-z0-9-*._~]*/)?[a-z0-9-~][a-z0-9-._~]*$ enforced a strict package name format. The new check only blocks a few obvious shell metacharacters but allows many potentially problematic characters (like spaces, quotes, backticks, dollar signs, parentheses, etc.). Consider keeping stricter validation or at minimum expanding the blocklist to include more dangerous characters like spaces, quotes (both single and double), backticks, dollar signs, and parentheses.

Potential open redirect vulnerability: The callbackUrl parameter is not validated before being used in a redirect. An attacker could craft a URL like "/signin?callbackUrl=https://evil.com" and the middleware would redirect authenticated users to the malicious site. Consider validating that the callbackUrl is a relative path or an allowed absolute URL before redirecting. You can check if it starts with "/" and doesn't contain "://" to ensure it's a relative URL, or use a whitelist of allowed domains.

Potential open redirect vulnerability: The callbackUrl from URL search params is not validated before being used for redirects and authentication. An attacker could set callbackUrl to an external URL, which would then be used by NextAuth for post-authentication redirects. Validate that callbackUrl is a relative path (starts with "/" and doesn't contain "://") before using it.

Using the all-zeros UUID (00000000-0000-0000-0000-000000000000) for the demo user could cause issues if the backend expects unique user IDs. This is a reserved/nil UUID in many systems and could conflict with validation logic or be treated specially by database systems. Consider using a properly generated UUID (e.g., uuid.v5 with a namespace and "demo@catwalk.live" as the name) to maintain uniqueness while still being deterministic and consistent across sessions.

| trustHost: true, |
There was a problem hiding this comment.
Setting trustHost to true bypasses host validation in NextAuth, which can be a security risk if not properly configured. This setting makes the application vulnerable to host header injection attacks where an attacker could manipulate the Host header to cause the application to generate URLs pointing to malicious sites. Unless running behind a properly configured reverse proxy that strips/validates the Host header, consider explicitly setting the AUTH_URL environment variable and removing trustHost, or at minimum ensure your deployment platform properly validates the Host header before it reaches your application.

Potential open redirect vulnerability: The callbackUrl is directly used without validation. An attacker could set callbackUrl to an external URL, causing the application to redirect users to a malicious site after authentication. Validate that callbackUrl is a relative path (starts with "/" and doesn't contain "://") or is from an allowed list of domains before using it in redirects.

assembling TRIAGED_ISSUES) violates the `${VAR}` style rule by using
`"$GITHUB_ENV"`; update the example to use `"${GITHUB_ENV}"` instead so it
follows the mandated variable format, while keeping the rest of the instruction
(minified JSON string enclosed in single quotes and written via echo into the
env file) unchanged.
In @.github/workflows/gemini-scheduled-triage.yml:
- Around line 67-87: The current job step 'find_issues' builds a
mutually-exclusive search ("no:label label:\"status/needs-triage\"") and writes
raw multi-line JSON into GITHUB_OUTPUT via a single echo, which yields empty
results and corrupts the output; change the GH CLI query to use the OR operator
(no:label OR label:"status/needs-triage") so it returns unlabeled OR
triage-labeled issues, and when setting the output variable
ISSUES/issues_to_triage use a heredoc to safely write multi-line JSON into
GITHUB_OUTPUT (e.g., open a here-document and append its contents to
"${GITHUB_OUTPUT}") rather than a single echo to avoid newline corruption.
- Around line 88-130: The workflow step with id 'gemini_issue_analysis' exposes
a secret-exfiltration risk by allowing the tool entry
"run_shell_command(printenv)" in the tools core list; remove that entry from the
settings block (the "tools.core" array) so the Gemini CLI cannot invoke
printenv, leaving other allowed run_shell_command(...) entries intact and
ensuring no operational dependency requires printenv before committing.
In `@backend/app/api/auth.py`:
- Around line 111-119: The info logs in the demo provisioning block expose PII
by logging user.email and demo_email; update the logger.info calls in the auth
demo-provisioning branch (the lines referencing demo_email and user.email) to
avoid raw emails—log only user.id and a boolean or masked indicator (e.g.,
"is_demo": true/false) and remove or mask demo_email; keep the same log messages
around get_encryption_service(), apply_demo_settings(db, user.id,
encryption_service) and db.commit() but replace any direct email values with the
non-PII identifiers.
In `@frontend/app/signin/page.tsx`:
- Around line 3-10: The SignInPage currently forwards the
searchParams.callbackUrl unchecked; validate it before appending to the redirect
URL by allowing only relative paths (start with "/") or checking against an
allowlist, and reject or drop any value that is an absolute URL or contains
suspicious schemes/hosts (update the logic around SignInPage, searchParams, and
callbackUrl). Apply the identical validation on the server side before calling
NextResponse.redirect(new URL(callbackUrl, req.url)) in the middleware (validate
callbackUrl and only construct the redirect when it passes the same
relative-path/allowlist checks; otherwise omit the param or redirect to a safe
default).
In `@frontend/auth.ts`:
- Line 196: Replace the hardcoded trustHost: true in frontend/auth.ts with a
deployment-time check using the AUTH_TRUST_HOST environment variable: remove the
literal trustHost entry from the NextAuth config and instead read
process.env.AUTH_TRUST_HOST (or let NextAuth v5 pick it up automatically) so
trust behavior is controlled by setting AUTH_TRUST_HOST=true in the environment;
ensure any code that previously relied on the literal trustHost setting
references the env-driven value (parse it to a boolean if you evaluate it
yourself) rather than the hardcoded symbol trustHost.
In `@frontend/middleware.ts`:
- Around line 38-42: The redirect uses an unchecked callbackUrl which allows
open-redirects; validate callbackUrl (from
req.nextUrl.searchParams.get("callbackUrl")) before calling
NextResponse.redirect: ensure it is a relative path (starts with "/") and does
not contain a scheme or host, default to "/dashboard" if invalid, and construct
the redirect with new URL(callbackUrl, req.url) only after validation; update
the logic around pathname, isAuthenticated, callbackUrl, and the
NextResponse.redirect call to enforce same-origin relative paths.

49-59: Add explicit empty string fallback for defensive clarity.GitHub Actions automatically casts null values to empty strings in

GitHub search syntax gh issue list no:label AND label status/needs-triage behavior
💡 Result:
In GitHub issues search, no:label means the issue has zero labels. So combining it with any label:… qualifier is mutually exclusive and will return no results:
no:label label:"status/needs-triage"⇒ empty set (can’t have no labels and a label at the same time). (docs.github.com)
Also, GitHub search doesn’t need an explicit AND keyword—a space is logical AND. For labels specifically: multiple label: qualifiers are AND; comma syntax inside label:"a","b" is OR. (docs.github.com)
If your intent is instead one of these, use:
-
Issues that need triage (have the label):
gh issue list --search 'label:"status/needs-triage"' -
Issues with no labels (unlabeled):
gh issue list --search 'no:label'(docs.github.com) -
Issues that do not have that triage label (may still have other labels):
gh issue list --search '-label:"status/needs-triage"'(docs.github.com)

GitHub Actions GITHUB_OUTPUT multi-line values JSON heredoc formatting
💡 Result:
To set a multi-line step output via GITHUB_OUTPUT, use the same delimiter (“heredoc”) form GitHub documents for multiline environment values:
# bash
json="$(jq -n '{foo:"bar",lines:["a","b"]}')" # example JSON (may contain newlines)
delim="EOF_$(uuidgen)" # pick a delimiter that won't appear alone on a line
{
echo "MY_JSON<<$delim"
printf '%s\n' "$json"
echo "$delim"
} >> "$GITHUB_OUTPUT"GitHub’s syntax is:
{name}<<{delimiter}
{value}
{delimiter}
…and GitHub explicitly notes you can set multi-line output values using this technique, with the warning that the delimiter must not occur on its own line inside the value. [1]
If your goal is to pass “multiline data” (including JSON) safely, a common approach is to serialize to single-line JSON (e.g., with jq --raw-input --compact-output --slurp) so it fits the normal name=value format, then fromJSON(...) when consuming it. [2]
Sources: [1] GitHub Docs: “Workflow commands for GitHub Actions” (multiline strings + setting an output parameter) https://docs.github.com/actions/using-workflows/workflow-commands-for-github-actions, [2] Jacob Strieb: “Reliable Multiline String Outputs from GitHub Actions Steps” https://jstrieb.github.io/posts/github-actions-multiline-outputs/
Search query returns empty results; raw JSON output to GITHUB_OUTPUT will corrupt with newlines.
The search no:label label:"status/needs-triage" is mutually exclusive—no:label finds issues with zero labels, while label:"status/needs-triage" requires that specific label present. These conditions cannot both be true, so the query returns nothing. Use no:label OR label:"status/needs-triage" to find either unlabeled issues or those marked for triage.
Additionally, writing raw JSON directly to GITHUB_OUTPUT will corrupt the output when issue bodies contain newlines. Use heredoc syntax to safely pass multi-line content:

Gemini CLI run_shell_command environment variables security
💡 Result:
-
What environment variables does
run_shell_commandget? It runs your command as a normal subprocess (e.g.,bash -con macOS/Linux; Windows differs by build/config), so it inherits the parent process environment by default, and it additionally setsGEMINI_CLI=1in the subprocess environment. This means any secrets present in your terminal/session env (tokens, cloud creds, etc.) are available to the command unless you’ve isolated/sandboxed the CLI. [1] -
Why this matters for security (env var exfiltration risk): A reported Gemini CLI flaw showed how an attacker could trick the CLI into running shell commands that exfiltrate environment variables (e.g., chaining
env+curl) in a way that wasn’t obvious to the user. Google fixed this in Gemini CLI v0.1.14 (fix released July 25, 2025, per reporting). [2][3] -
Recommended mitigations:
- Update to v0.1.14+ (or current latest) to get the patched behavior and improved command visibility/approvals. [2][3]
- Use sandboxing/containment (e.g., Docker/Podman/macOS Seatbelt integrations) so even if a command runs, it can’t freely read host secrets. [2][3]
- Prefer allowlisting via
coreTools/tools.coreto strictly limit what shell commands can run; don’t rely onexcludeToolscommand patterns as a security boundary (docs note it’s simple string matching and can be bypassed). [1][4]

🌐 Web query:
Google Gemini CLI printenv secrets logs telemetry exposure
💡 Result:
- Telemetry is opt-in, but can export data off-box if enabled. Gemini CLI’s OpenTelemetry is disabled by default (
GEMINI_TELEMETRY_ENABLED/telemetry.enabled: false). If you enable it, it can write local files (e.g..gemini/telemetry.logor collector logs under~/.gemini/tmp/...) or export to Google Cloud Logging/Monitoring/Trace whentarget: "gcp"is used. [1] - Prompts may be logged unless you turn that off. Telemetry has a
logPromptsswitch (env:GEMINI_TELEMETRY_LOG_PROMPTS, CLI:--telemetry-log-prompts/--no-telemetry-log-prompts). The docs show prompt text is included unless prompt logging is disabled. [1] - Tool calls (including shell commands) are logged with arguments. Telemetry logs a
gemini_cli.tool_callevent with fields includingfunction_nameandfunction_args. That means if the model runs a shell tool with something likeprintenv/env, the command invocation itself is captured in telemetry; and if the resulting env-var contents get echoed into prompts/output, those can also end up in whatever backend you export to. [1] - There was a real-world risk of env-var exfiltration via tool execution. Tracebit reported an issue where Gemini CLI’s command “whitelist” matching could be bypassed to run a second-stage command that exfiltrated all environment variables (potentially containing secrets) using
env/curl; Google fixed this in Gemini CLI v0.1.14. [2]
Practical mitigations
- Keep telemetry disabled unless you explicitly need it; if enabled, set
--no-telemetry-log-prompts(orGEMINI_TELEMETRY_LOG_PROMPTS=false). [1] - Treat
printenv/envoutput as secrets: don’t run it in sessions where prompts/logs/telemetry are exported or persisted. - Avoid running Gemini CLI in untrusted repos and prefer sandboxing (the fix and guidance were issued after the whitelist-bypass report). [2]

google-github-actions run-gemini-cli documentation shell command access
💡 Result:
To give Gemini CLI shell-command access when running via google-github-actions/run-gemini-cli, you configure the CLI’s workspace settings through the Action’s settings input (it writes a JSON string to your-project/.gemini/settings.json). (github.com)
1) Enable / control shell access in Gemini CLI
Gemini CLI runs OS commands via its Shell Tool: run_shell_command(command="..."). (google-gemini.github.io)
Shell behavior (including interactive support) is controlled by tools.shell.* in settings.json (workspace settings live at your-project/.gemini/settings.json). (geminicli.com)
Example Action step enabling interactive shell (if you need it):
- uses: google-github-actions/run-gemini-cli@vX
with:
settings: |
{
"tools": {
"shell": {
"enableInteractiveShell": true,
"showColor": true
}
}
}tools.shell.enableInteractiveShell is the setting that turns on interactive command support for run_shell_command. (google-gemini.github.io)
2) What “shell access” means in GitHub Actions
Any run_shell_command calls will execute on the GitHub Actions runner (i.e., the VM/container hosting the job), so it can run typical CLI tools available there (and anything you install earlier in the workflow). (google-gemini.github.io)

Remove run_shell_command(printenv) from Gemini tools allowlist.
Allowing run_shell_command(printenv) risks leaking secrets and service credentials. The subprocess inherits all parent environment variables, and Gemini CLI's telemetry (enabled in this workflow) logs tool calls including command invocations. A prior vulnerability (fixed in v0.1.14) demonstrated how such commands can be chained to exfiltrate environment variables containing secrets. Remove printenv unless there's a documented operational need.

NextAuth.js v5 trustHost option configuration documentation
💡 Result:
trustHost is an Auth.js / NextAuth.js v5 config option documented here: (authjs.dev)
It exists because Auth.js uses the incoming request Host header; setting trustHost: true tells Auth.js it’s safe to rely on that header (and, when behind proxies, forwarded host/proto headers), assuming your platform sets them safely. (authjs.dev)
How to configure (v5)
Option 1: In your NextAuth/Auth.js config
Set it on the object you pass to NextAuth(...):
import NextAuth from "next-auth"
export const { handlers, auth, signIn, signOut } = NextAuth({
trustHost: true,
providers: [],
})(Any equivalent “auth config object” you pass to Auth.js/NextAuth v5 supports trustHost.) (authjs.dev)
Option 2: Via environment variable (recommended behind a reverse proxy)
Auth.js documents AUTH_TRUST_HOST=true for deployments behind a reverse proxy (trusts X-Forwarded-Host; also auto-inferred on some platforms like Vercel / Cloudflare Pages). (authjs.dev)

Use environment variable AUTH_TRUST_HOST=true instead of hardcoding in config.
NextAuth v5 recommends setting this via the AUTH_TRUST_HOST environment variable for deployments behind reverse proxies, rather than hardcoding it in the config file. This allows the trust behavior to be controlled at deployment time without config changes. If your hosting platform requires Host header trust (e.g., behind a proxy or load balancer), set AUTH_TRUST_HOST=true in your environment instead of the hardcoded trustHost: true in auth.ts.
🤖 Prompt for AI Agents
In `@frontend/auth.ts` at line 196, Replace the hardcoded trustHost: true in
frontend/auth.ts with a deployment-time check using the AUTH_TRUST_HOST
environment variable: remove the literal trustHost entry from the NextAuth
config and instead read process.env.AUTH_TRUST_HOST (or let NextAuth v5 pick it
up automatically) so trust behavior is controlled by setting
AUTH_TRUST_HOST=true in the environment; ensure any code that previously relied
on the literal trustHost setting references the env-driven value (parse it to a
boolean if you evaluate it yourself) rather than the hardcoded symbol trustHost.

Potential inconsistency: mcp_config is sourced from schedule_config instead of the newly populated deployment.mcp_config.
Lines 93-99 populate deployment.mcp_config with runtime and version info, but line 116 derives mcp_config from deployment.schedule_config. This means the runtime/version just persisted won't be passed to FlyDeploymentService.create_machine(). Consider using the already-populated deployment.mcp_config instead.

Missing error handling for fetch failures.
Unlike the [action]/route.ts file which wraps fetch in try-catch, this route doesn't handle network errors. If the backend is unavailable, users will see an unhandled exception.

📝 A Collaboration Story: From Crash-Loops to Clear Skies
Hey team! Today we have a special update born from a high-bandwidth collaboration between our Lead Engineer and the AI Orchestrator.
🎭 The Plot
Our Fly.io machines were caught in a tragic 'Crash-Loop'—waking up only to find they'd forgotten how to import their own authentication dependencies. Meanwhile, the database was quietly closing its doors on idle connections, leading to mysterious 500 errors that haunted our /api/deployments endpoint.
🛠️ The Heroic Feats
Together, we dove into the logs and performed some surgical strikes:
🌟 The Moral of the Story
When human intuition meets AI analysis, bugs don't stand a chance. We've turned a series of cascading failures into a stable, production-ready foundation.
Next Step: ly deploy and watch the machines breathe easy! 🌬️✨
