What it does

Con CLI E2E is an agent skill from nowledge-co/con-terminal. Validate Con's local socket control plane against a real running app session, and write/run con-test integration tests. Use when testing con-cli, the Unix socket API, pane control, tmux control, in-session agent calls, or when writing E2E test cases in crates/con-test/testdata/.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering End-to-end testing, Integration testing and Test generation. It works with tmux. The repository describes itself as: The Native Terminal Emulator with a builtin AI Harness. The licence is MIT.

When your agent uses it

Testing con-cli
The Unix socket API
In-session agent calls

Example prompts

“/con-cli-e2e”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

Build the relevant crates.
Launch cargo run -p con.
Wait for /tmp/con.sock.
Use con-cli --json identify, tabs list, and panes list before acting.
Only use panes exec on panes that expose exec_visible_shell.
Use tree / surfaces list only for pane-local surface validation.
After surfaces create or surfaces split, use surfaces wait-ready --surface-id --timeout 10 before sending input that assumes an…
Use agent ask to verify the real in-tab built-in agent session.

What it can do on your machine

Read from SKILL.md and the folder at commit 21089e5. 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
Shell commands in SKILL.md call:
- cargo
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

Con CLI E2E loads about 1.2k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 522 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~73
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

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); files beside SKILL.md are not scanned.

description: Validate Con's local socket control plane against a real running app session, and write/run con-test integration tests. Use when testing con-cli, the Unix socket API, pane control, tmux control, in-session agent calls, or when writing E2E test cases in crates/con-test/testdata/.

con-cli E2E & con-test

Use this skill when the task is to verify that Con's CLI/control plane works against a live app window, or when writing/fixing integration tests in crates/con-test/testdata/.

Primary reference:

Read docs/impl/con-cli-e2e.md for the full workflow and current live limitations.

con-cli manual E2E

Default workflow:

Build the relevant crates.
Launch cargo run -p con.
Wait for /tmp/con.sock.
Use con-cli --json identify, tabs list, and panes list before acting.
Only use panes exec on panes that expose exec_visible_shell.
Use tree / surfaces list only for pane-local surface validation.
After surfaces create or surfaces split, use surfaces wait-ready --surface-id <id> --timeout 10 before sending input that assumes an initialized shell.
Use agent ask to verify the real in-tab built-in agent session.

Rules:

Prefer --json for every command in automated evaluation.
Prefer pane_id over pane_index for follow-up actions.
Prefer surface_id for follow-up actions only when testing the explicit surfaces.* API.
Keep existing pane and agent benchmarks on panes.*; surfaces are additive and must not change the built-in agent's pane model.
After visible execution, confirm the pane still reports shell_prompt and keeps exec_visible_shell.
If agent ask fails, check provider config/env before blaming the socket layer.

Known current limit:

panes create now reports surface_ready, is_alive, and has_shell_integration, but startup-command panes can still be in a non-shell foreground state immediately after creation. Treat them as provisional until panes list confirms the capabilities you need for the next step.

con-test integration tests

con-test is the E2E test runner for integration and interactive behavior. It launches a real con session, runs .test files against it via con-cli, and checks output.

Running tests

bash

# Build first
cargo build

# Run all tests
./target/debug/con-test crates/con-test/testdata/

# Run a single file
./target/debug/con-test crates/con-test/testdata/panes/split.test

Show full SKILL.md (250 more words)Show less

Test file format

Test files live in crates/con-test/testdata/<group>/<name>.test. Each step is a con-cli command followed by an assertion block:

# comment
con-cli --json <command>   # step description
---- <assertion>
<expected>

Assertion types:

Assertion	Meaning
`---- ok`	Command exits 0 (any output accepted)
`---- contains`	stdout contains the literal string on the next line
`---- json-subset`	actual JSON is a superset of the expected JSON (subset match, deep)

The json-subset assertion only checks the keys you specify — extra fields in the actual output are ignored. Use it to assert specific fields without coupling to the full response shape.

Writing new tests

Unit-test functions in Rust (#[cfg(test)]) for logic. Use con-test only for integration and interactive behavior that requires a live session.
No low-value tests — don't write tests just to hit coverage. Every test should catch a real bug or document a real contract.
Group tests by domain: panes/, tabs/, agent/, system/.
After panes create, always add a panes wait step before asserting is_alive — the new pane's surface may not be ready immediately.
For agent panel tests, use agent open-panel-for-request to drive the motion state, then agent panel-state to assert the result.

Example test

# panes/split.test
con-cli --json panes list --tab 1  # start with 1 pane
---- json-subset
{"panes":[{"index":1}]}

con-cli --json panes create --tab 1 --location right  # split right
---- ok

con-cli --json panes wait --tab 1 --pane-index 2 --timeout 5  # wait for new pane
---- ok

con-cli --json panes list --tab 1  # both panes alive
---- json-subset
{"panes":[{"is_alive":true},{"is_alive":true}]}

Fixing failures

When a test fails with expected JSON is not a subset of actual JSON, the actual output is printed in full. Check:

Is the command missing (unrecognized subcommand)? → Add the subcommand to con-cli and the ControlCommand handler.
Is a field wrong/missing? → Fix the handler's response shape.
Is the assertion racing (e.g. is_alive: false right after create)? → Add a panes wait or surfaces wait-ready step before the assertion.
