Agent Browser Cookie Manager

Use this skill to export cookies from an agent-browser session, store them under this skill’s folder, and reapply them to another session.

What This Skill Provides

• •Deterministic export of cookies to assets/cookies/
• •Reapplication of cookies to another session (with optional base URL)
• •Safe filtering by domain when reapplying

Files and Locations

• •Exported cookies live in assets/cookies/ as JSON files.
• •Use scripts/export_cookies.py and scripts/import_cookies.py.

Workflow

Export cookies from a session

1. •Ensure the session you want to export from is active.
2. •Run:
   bash

   python /Users/jace/.codex/skills/agent-browser-cookies/scripts/export_cookies.py \
     --session default \
     --name default-localhost
   

3. •Verify output file in:
   code

   /Users/jace/.codex/skills/agent-browser-cookies/assets/cookies/default-localhost.local.json
   

Import cookies into a different session

1. •Decide the base URL (origin) the cookies should apply to, e.g. http://localhost:3208.
2. •Run:
   bash

   python /Users/jace/.codex/skills/agent-browser-cookies/scripts/import_cookies.py \
     --session test-cookie \
    --file /Users/jace/.codex/skills/agent-browser-cookies/assets/cookies/default-localhost.local.json \
    --base-url http://localhost:3208
   

3. •Open the target page in that session and verify login state.

Notes and Constraints

• •agent-browser cookies set only sets name/value for the current origin.
• •The import script filters cookies to the base URL host and applies them after opening that URL.
• •If login still fails, cookies may be missing attributes; re-login manually and re-export.
• •Cookie files are stored as *.local.json and are ignored by assets/cookies/.gitignore.
