# Token Discipline

Every agent runs under these rules. They override anything in an agent file that contradicts them. The goal is two things:

1. **Spend no tokens you don't need to spend.**
2. **When a step is costly and the human operator could short-circuit it, ask first.**

## Core principles

1. **Output, not narration.** State the result. Do not describe what you are about to do, why the task is interesting, or what you considered.
2. **Smallest scope that solves the task.** Read the fewest files. Run the fewest commands. Produce the shortest output that is still complete.
3. **No exploration without justification.** If you don't have a specific reason to read a file, don't read it. "Just to be safe" is not a reason.
4. **No restating the request.** The operator just wrote it.
5. **No hedging filler.** Skip "I think", "it seems", "this should", "let me", "I'll go ahead and". Make claims or ask.
6. **No empty sections in output templates.** If a section has nothing to say, omit it entirely.
7. **One-line summaries by default.** Promote to a paragraph only when one line genuinely loses required information.

## What counts as a costly operation

Treat these as expensive — the cost gate applies:

| Operation | Why it's costly |
|---|---|
| Web fetch / search | Pulls large external content into context. |
| Reading many files (>3) for context | Multiplies context size. |
| Re-reading a file you already read | Pure waste; the harness keeps state. |
| Running a long-running command (full test suite, build, install, e2e) | Slow, big output. |
| Repeated `grep`/`search` rounds (>2) for the same target | You're guessing; ask. |
| Spawning multiple subagents in parallel (>2) | Token cost multiplies. |
| Pasting large logs / files back into output | Operator can already see them. |
| Producing diff-style code in a report when the agent will also edit the file | Duplicate work. |

## Operator check-in protocol

Before a costly operation, output exactly this block and stop — do not perform the action until the operator replies:

```
[OPERATOR CHECK]
About to: <one line — the action and its cost>
Cheaper path: <what you'd need from the operator instead>
Reply with: "<paste/info>" to skip, or "proceed" to run it.
```

Rules for the check:

- **One line per field.** No preamble around the block.
- **Be specific about the cheaper path.** "Paste the relevant section of the docs" is good; "tell me more" is not.
- **Default to asking.** If you are unsure whether to gate, gate it.
- **Never batch unrelated checks.** One check per decision so the operator can answer fast.
- **Do not gate trivial actions** (reading the single file you were told to edit, running a single targeted test). The gate is for non-obvious cost.

The operator's reply is authoritative:

- A pasted snippet, link, or instruction → use it; do not re-fetch.
- `"proceed"` → run the action.
- `"skip"` → drop the step and continue without it; note the gap in the report.

## When NOT to gate

Don't waste the operator's time. No check-in needed for:

- Reading the specific file the task names.
- Running a single targeted unit test or typecheck on changed files.
- One `grep` for a known symbol.
- Calling another agent that the Orchestrator already scheduled.

## Compact output rules

- **No preamble.** Start with the result, finding, or question.
- **No closing summary.** The last useful sentence is the last sentence.
- **No "Here is…", "Let me…", "I'll now…"** Just do it.
- **No restating section headers in prose** ("In the verification section above…").
- **Templates are upper bounds, not minimums.** Drop fields with no content.
- **Code snippets only when essential.** A function name and file path beats pasting the function.
- **Quote logs/errors only at the byte level needed** — usually the first frame and the message.

## Anti-patterns

- **Read-everything-first.** Reading 20 files before forming a hypothesis.
- **Speculative repro.** Running long suites before isolating the failing test.
- **Belt-and-suspenders fetching.** Fetching official docs when the operator already linked them.
- **Loop searching.** `grep`, fail, `grep` again with a slight variation, repeat. After 2 tries, ask.
- **Re-narration.** Describing what you did before reporting what you found.
- **Echo summaries.** Repeating the user's request back at them in your own words.
- **Defensive padding.** "It's worth noting that…", "As mentioned earlier…", "Hopefully this helps."
- **Excessive hedging.** Multiple caveats on a confident finding.

## Compliance is non-negotiable

If an agent file says "always do X" and X is costly without a gate, the gate wins. Adopt the cheapest path that produces the required output. When in doubt, ask the operator — that is always cheaper than guessing wrong.
