What it does

Testing Marchat is an agent skill from Cod-e-Codes/marchat. Writes and runs marchat tests with race detection, coverage, and dialect smoke patterns. Use when adding tests, fixing test failures, measuring coverage, or when the user mentions go test, -race, TESTING.md, or CI database smoke.

Its SKILL.md is about 800 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 Failing and flaky tests. It works with Go and MySQL. The repository describes itself as: Terminal chat for developers: Go WebSocket server + Bubble Tea TUI client, optional E2E, reactions, DMs, channels, plugins, files, code snippets, admin UI. Backends: SQLite… The licence is MIT.

Example prompts

“Use the testing-marchat skill to write and runs marchat tests with race detection, coverage, and dialect smoke patterns”
“/testing-marchat”

What it can do on your machine

Read from SKILL.md and the folder at commit 3440f09. 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:
- go
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

Testing Marchat loads about 802 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 312 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~802

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: Writes and runs marchat tests with race detection, coverage, and dialect smoke patterns. Use when adding tests, fixing test failures, measuring coverage, or when the user mentions go test, -race, TESTING.md, or CI database smoke.
paths: **/*_test.go, TESTING.md

Testing marchat

Authoritative tables and file list: TESTING.md. Do not weaken tests to make CI pass.

Commands

Main module (repo root). developing-marchat requires both plain and race runs after substantive changes:

bash

go test ./...
go test -race ./...
go test -coverprofile=mergedcoverage ./...
go tool cover -func=mergedcoverage

Nested SDK (separate go.mod; not in root merged coverage):

bash

cd plugin/sdk && go test -coverprofile=sdkcover ./... && go tool cover -func=sdkcover

On Windows PowerShell, prefer a cover profile name without a .out suffix (e.g. mergedcoverage, coverage).

Stale cache:

bash

go clean -cache -testcache

Patterns

Area	Pattern
SQL / handlers	In-memory SQLite; table-driven cases in `server/*_test.go`
Postgres / MySQL	`server/db_ci_smoke_test.go`; skip locally unless `MARCHAT_CI_POSTGRES_URL` / `MARCHAT_CI_MYSQL_URL` set; MySQL DSN uses `mysql:` or `mysql://` prefix
Doctor env	`internal/doctor/env.go`: swap `osEnviron` under `environMu`; no `t.Parallel()` with other tests that swap it
TUI client	Inject `tea.Msg`; no real terminal; `testmain_test.go` sets Lipgloss ANSI256 for SGR assertions
Client render	`render_test.go`: URL wrap/hyperlink (headless); URL click/index helpers do not prove real-terminal opens; see `TESTING.md` Manual testing gaps
cmd/server	Subprocess pattern in `cmd/server/subprocess_doctor_test.go`
Plugins	`plugin/host/plugin_lifecycle_test.go` builds minimal plugin with `go build`
Race	CI runs `go test -race ./...`; plugin host `StopPlugin` must drain readers before reuse

Set MARCHAT_DOCTOR_NO_NETWORK=1 in tests that hit doctor update checks.

Coverage

Main module overall statement coverage: see README.md and TESTING.md (regenerate; do not guess).
plugin/sdk: measure separately (see TESTING.md).
After material shifts (about 0.2% or new test files), update figures in README.md and TESTING.md.

Anti-patterns (never do these)

Skipping -race or nested plugin/sdk module when relevant code changed
time.Sleep for synchronization without strong justification
Fudging assertions, deleting tests, or conditional passes (if os.Getenv(...) { t.Skip() } without CI contract) to green CI
Asserting only substring presence when ordering or side effects matter
Schema changes tested only on SQLite when dialect SQL diverges
Claiming tests pass without running go test on touched packages

Checklist

New behavior has a focused test
go test ./... passes; -race when touching concurrency
plugin/sdk tested if SDK touched
go test -coverprofile=mergedcoverage ./... and refresh README.md / TESTING.md when totals shift materially (~0.2% or new test files)
Report actual go test outcome in the final response
