  • Smoke-testing cctop end to end — verifying a real coding-agent session is tracked and shows in the panel

What it does

E2E Session Test is an agent skill from st0012/cctop. Use when smoke-testing cctop end to end — verifying a real coding-agent session is tracked and shows in the panel. Trigger on "smoke test sessions", "verify session tracking", "test the hook pipeline", "check cctop picks up a claude/codex/opencode/pi session", or "run the e2e test", even without the word "skill". Creates a real CLI agent session in a terminal, confirms cctop tracks it, opens the panel programmatically, and captures screenshot proof.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/troubleshooting.md`, `scripts/cctop-sessions.sh` and `scripts/launch-cli-session.sh`).

It sits in Testing & QA, covering End-to-end testing and QA and bug reports. It works with macOS. The repository describes itself as: A keyboard-first menubar app to monitor and jump between AI coding sessions — minimum setup required. The licence is MIT.

When your agent uses it

  • Smoke-testing cctop end to end — verifying a real coding-agent session is tracked and shows in the panel
  • Smoke test sessions
  • Verify session tracking
  • Test the hook pipeline

Example prompts

  • “smoke test sessions”
  • “verify session tracking”
  • “test the hook pipeline”
  • “/e2e-session-test”

Requirements

  • A Bash shell

What it can do on your machine

Read from SKILL.md and the folder at commit 4ee2258. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Shell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

E2E Session Test loads about 727 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 118 tokens; SKILL.md has 273 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~118
When it runs · the whole SKILL.md, loaded when a task matches
~727
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Use when smoke-testing cctop end to end — verifying a real coding-agent session is tracked and shows in the panel. Trigger on "smoke test sessions", "verify session tracking", "test the hook pipeline", "check cctop picks up a claude/codex/opencode/pi session", or "run the e2e test", even without the word "skill". Creates a real CLI agent session in a terminal, confirms cctop tracks it, opens the panel programmatically, and captures screenshot proof.

cctop end-to-end session test

Verify a real session flows all the way through:

agent in a terminal → cctop hooks → ~/.cctop/sessions/<pid>.json → panel card

A good smoke test after touching hooks, the session schema, or the panel.

Capabilities, not tools

Harness-agnostic — it needs three generic capabilities. Use your environment's equivalent; don't assume a specific tool:

  • run shell commands
  • capture a screenshot of the screen (or fall back to the screencapture CLI)
  • view an image you captured

Create the session with a CLI agent in a terminal

Drive a CLI agent (claude / codex / opencode / pi) in a terminal window — it's a real session and one shell command starts it. Don't try to puppet a desktop agent's GUI: if it's the app hosting you, screen capture hides its window and you can't confirm input landed (see references/troubleshooting.md). Requires a cctop build with the cctop:// URL scheme (ships with this skill).

Steps (run from the repo root)

bash
# 1. Baseline — note the PIDs
.claude/skills/e2e-session-test/scripts/cctop-sessions.sh

# 2. Create a session — opens a terminal running the agent, waits for it to register
.claude/skills/e2e-session-test/scripts/launch-cli-session.sh claude ~/projects/cctop

# 3. Verify — a new PID entry with the right source (cc/codex/opencode/pi) appears
.claude/skills/e2e-session-test/scripts/cctop-sessions.sh

# 4. Summon the panel
open cctop://toggle

Then capture a screenshot and confirm the new session's card is in the panel (right status, source, project). Run open cctop://toggle again to close it — a clean closed/open pair if you want before/after proof. For a shareable record, write a small HTML log embedding the screenshots.

Two details the launcher handles, because they otherwise make this fail silently: a login shell (so the agent's PATH, e.g. ~/.local/bin, resolves) and a trusted directory (so the agent doesn't stall at a folder-trust prompt). open cctop://toggle is used instead of a menu-bar click or hotkey because those need extra OS permissions under automation.

PASS

  • New tracked session within ~5s, correct source.
  • open cctop://toggle opens and closes the panel.
  • A screenshot shows the card.

On failure, grab the relevant ~/.cctop/logs/<session>.log entry and see references/troubleshooting.md.
