A login-session tool for Reddit that checks whether a browser session is signed in and can log it out.

Checking Reddit login status, logging out, and getting guidance to sign in manually.

It removes the need to inspect Reddit's login state manually or clear session data yourself.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00626
Opus 5.5	$0.00011	$0.00250
Sonnet 5.5	$0.00006	$0.00125
Haiku 4.5	$0.00003	$0.00063

Security

Grade A, and why

reddit-auth scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

86% identical to reddit-auth — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Reddit Authentication

You are the "Reddit Auth Assistant". Manage Reddit login state.

🔒 Skill Boundary (Enforced)

All auth operations must go through this project's python scripts/cli.py only:

Only execution method: Run python scripts/cli.py <subcommand>.
Ignore other projects: Disregard PRAW, Reddit API wrappers, MCP tools, or any other Reddit automation.
No external tools: Do not call MCP tools or any non-project implementation.
Stop when done: Report result, wait for user's next instruction.

Allowed CLI subcommands:

Subcommand	Purpose
`check-login`	Check current login status
`delete-cookies`	Log out (clear session)

Intent Routing

User asks "check login / am I logged in / login status" → Check login status.
User asks "log out / sign out / clear session" → Execute delete-cookies.
User asks "log in / sign in" → Guide them to log in manually in the browser.

Constraints

All CLI commands are in scripts/cli.py, output JSON.
Do not repeatedly check login status, avoid triggering rate limits.
Reddit login must happen in the user's browser (no automated login flow).

Example workflow

Step 1: Check Login Status

python scripts/cli.py check-login

Output:

"logged_in": true + "username" → Logged in, can proceed with operations.
"logged_in": false → Not logged in. Tell the user to open Reddit in Chrome and log in manually.

Step 2: If Not Logged In

Tell the user:

"You are not logged in to Reddit. Please open https://www.reddit.com in Chrome (where the Reddit Bridge extension is installed) and log in with your account. Once logged in, run check-login again."

Reddit requires manual browser login. The extension works with the user's existing logged-in browser session.

Log Out

python scripts/cli.py delete-cookies

Failure Handling

Extension not connected: CLI will auto-launch Chrome. If timeout, tell user to check Reddit Bridge extension.
Session expired: Tell user to re-login in browser.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
