What it does

Formax Slash Command Workflow is an agent skill from yusifeng/formax. Use when adding/modifying Formax slash commands (/permissions /agents /hooks /todos etc), especially output rendering (command sublines), overlay dismiss messages, and whether outputs are injected into the next LLM turn.

Its SKILL.md is about 1k 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 Agent Workflows, covering Hooks and plugins. The repository describes itself as: Terminal-first AI assistant for software engineering tasks (inspired by Claude Code v2.0.67). The licence is MIT.

When your agent uses it

  • Adding/modifying Formax slash commands (/permissions /agents /hooks /todos etc)
  • Especially output rendering (command sublines)
  • Overlay dismiss messages
  • Whether outputs are injected into the next LLM turn

Example prompts

  • “/formax-slash-command-workflow”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Command discovery + dispatch
  2. Command result contract (UI vs model)
  3. Overlay dismissal “subline output”
  4. REPL message plumbing + rendering

What it can do on your machine

Read from SKILL.md and the folder at commit 1b0c3f3. 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:

    • bun

    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

Formax Slash Command Workflow loads about 1k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 363 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

Formax slash command workflow

Goal

Use this skill when changing slash command discovery, dispatch, overlay dismissal output, or next-turn injection behavior.

Read First

  • docs/contracts/slash-command-contract.md
  • docs/contracts/semantics-contract.md when command behavior crosses canonical UI messages or routing
  • docs/contracts/config-settings-contract.md when the change touches /config

These docs are canonical. If stable behavior changes, update them before or with code.

Code Map

1) Command discovery + dispatch
  • packages/core/src/features/commands/registry.ts: command list/suggest/dispatch wiring
  • packages/core/src/features/commands/CommandStore.ts: disk scanning + precedence (project overrides user)
  • packages/core/src/features/semantics/core/commandRouting.ts: exact /clear / /compact and command-dispatch routing boundary
2) Command result contract (UI vs model)
  • packages/core/src/features/commands/contracts.ts: UiEffect / UiMessage / ModelEffect shapes
  • packages/core/src/features/commands/adapter.ts: maps command execution output → CommandResult
  • packages/core/src/features/repl/controller/send/send.ts: consumed slash handling, local_async, and injected-block plumbing
3) Overlay dismissal “subline output”
  • packages/core/src/features/repl/controller/ui/overlays.ts: overlay open/close + append “dismissed” sublines
4) REPL message plumbing + rendering
  • packages/core/src/features/repl/controller/send/send.ts: applies UiEffect.appendMessages to Msg
  • packages/core/src/screens/REPL.tsx: render msg.ui.kind === 'command_subline' as ⎿ ... (no ⏺)
  • packages/core/src/screens/REPL.slashSuggestions.test.tsx: duplicate command selection / preferredSlashSpecId

High-Signal Patterns

  • Pattern A: one-line overlay dismissal
    • append a single assistant Msg with ui.kind='command_subline'
    • keep copy stable unless the user explicitly requests copy changes
  • Pattern B: multi-line local output
    • split output into multiple command_subline rows
    • this is UI only; model injection remains separately controlled
  • Pattern C: inject-but-don't-spam
    • when a command needs to inform the model, keep UI output minimal and preserve recordForNextTurn / injected-block behavior separately

Minimal Workflow

  1. Classify the change first: discovery / precedence, local UI output, next-turn injection, or overlay dismiss behavior.
  2. Update the slash command contract first.
  3. Preserve “show in UI” vs “inject into model context” as separate concerns; local output alone must not imply injection.
  4. Use command_subline for Claude-style sublines; do not invent new message shapes.
  5. Run the minimum regression set below before review.

Minimum Regression

  • bun run test -- packages/core/src/features/commands/registry.test.ts packages/core/src/features/commands/CommandStore.test.ts packages/core/src/features/commands/adapter.test.ts packages/core/src/features/commands/contracts.test.ts
  • bun run test -- packages/core/src/features/repl/controller/ui/overlays.test.tsx
  • bun run test -- packages/core/src/features/repl/controller/send/send.test.ts packages/core/src/features/repl/useReplController.test.tsx
  • bun run test -- packages/core/src/screens/REPL.slashSuggestions.test.tsx packages/core/src/screens/repl/inputHint.test.ts
  • bun run type-check when command shapes or routing plumbing changes

Guardrails

  • Do not add bespoke commandSubLines-style structures; use Msg.ui.kind='command_subline'.
  • Do not change UI copy / spacing / colors as a side-effect of routing changes.
  • Do not patch only overlay output if the real bug is discovery or dispatch precedence.
  • If behavior is unclear, add or extend an Ink test first; tests are not the only spec, but they should lock the visible key path.
