Pin the Harness at 1664eaf3 and drop the output row by vinniefalco · Pull Request #23 · cppalliance/runvil-workshop

vinniefalco · 2026-11-14T15:15:47Z

Moves the Harness pin to the merge of cppalliance/runvil-harness#15 and takes the declared output file out of the Run window's contract.

What changes

The four runvil-harness entries in Cargo.toml name 1664eaf363569d629d8ec65f3e0381bded3449bd. Cargo.lock changes only the 15 source lines of those crates.
A prompt returns its output as its return value, so the frontmatter has no output: key. POST /prompts/contract sends no output field: ContractResponse loses the field, and FileDto is deleted.
run-api.ts does not narrow output, and run-rows.ts draws no output row. The old client refused a contract with the key missing, so the route and the client change in one commit.
The Engine definition in AGENTS.md lists "a store operation" as the last effect, the same text as in runvil-harness and runvil.

What does not change

No code that runs a prompt changes. Workshop reads report.result and report.unread, and it never read the output file.
The tests that write /out.md through std/write and bash/shell stay as they are. They work in the files a run's tools see, not in the run's store.

Summary by CodeRabbit

Changes
- Prompt contracts no longer include output-file details.
- The Run window no longer displays an output row; it now presents rows for top-level arguments.
Documentation
- Updated the description of Run window rows to reflect the information shown.

The Engine at `1664eaf363569d629d8ec65f3e0381bded3449bd` has no `output:` frontmatter key, because a prompt returns its output as its return value. The four `runvil-harness` entries in `Cargo.toml` name that commit, the contract route sends no `output` field, and the Run window draws no output row. - `ContractResponse` has no `output` field. `FileDto` and its `From<&FileDecl>` impl are deleted. - `run-api.ts` does not narrow `output`, and `RunContractFile` and `parseFile` are deleted. The old narrowing refused a contract with the key missing, so the route and the client change together. - `run-rows.ts` draws no `output` row. A prompt with no arguments shows the `name` and `max_tool_iterations` rows alone. - `Cargo.lock` changes only the 15 source lines of the crates that come from `runvil-harness`. - No other code, test, or prompt changes with the pin. - The tests of the route and the Run window lose their `output` fixtures and assertions. No test here covers a prompt that still declares `output:`. Plan: runvil-harness/plan/2026-11-14-1-private-store.plan.md

The definition of the Engine in `AGENTS.md` lists what a run asks its caller for, and the last item was "a file outside a prelude's install". It now says "a store operation", which is the effect the Engine at the pinned commit emits. - The diff changes one line of one document. It changes no code and no test. Plan: runvil-harness/plan/2026-11-14-1-private-store.plan.md

Walkthrough

The prompt contract response and UI no longer include the output file field. Tests reflect this change. Four runvil-harness dependencies use a new pinned revision, and the Engine definition now describes a store-operation condition.

Changes: Run contract output removal

Layer / File(s)	Summary
Server contract response `crates/workshop/server/src/routes/prompts.rs`, `crates/workshop/server/src/routes/prompts-tests.rs`	The response no longer includes the output file. Contract tests no longer check for the output field.
UI parsing and rendering `crates/workshop/ui/src/services/run-api.ts`, `crates/workshop/ui/src/parts/run/run-rows.ts`, `crates/workshop/ui/test/run-api.mjs`, `crates/workshop/ui/test/run-panel.mjs`	The UI contract parser and rendered rows no longer include the output field. Related fixtures and assertions reflect its removal.

Harness dependency revisions

Layer / File(s)	Summary
Pinned dependency revision `Cargo.toml`	The four `runvil-harness` dependencies now use revision `1664eaf363569d629d8ec65f3e0381bded3449bd`.

Engine definition

Layer / File(s)	Summary
Store-operation condition `AGENTS.md`	The Engine definition now describes a store-operation condition instead of a file outside a prelude install.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · up to 623eb

Prompts that still declare output: will now fail to parse instead of producing a Run contract, and no test guards that behavior. The gap is small and bounded; one route test closes it.

Explanation

The title names the two main changes: pinning the Harness dependency to commit 1664eaf3 in Cargo.toml, and removing the output row from the Run window. The raw summary and objectives confirm both changes, including the removal of the output field from the contract response and UI. Other changes (the AGENTS.md Engine wording, test updates) are supporting details that the title does not need to cover.

Test rejection of the removed frontmatter key.

The new parser removes output and denies unknown fields. A prompt that declares output: therefore receives a parse error instead of a Run contract. (raw.githubusercontent.com) Add a route test for that rejection; the existing write tests do not cover it. This does not require backward compatibility.

As per coding guidelines, “Behavior changes ship with tests in the same change.”
