# #26892 runtime transcript (synthetic repo, real writer CLIs run with the repo as cwd, as T3's writers run)

The PR prompt is built by `buildPrContentPrompt` from the checkout under test. Before = main 58e60bf5e8 (no producer data exists). After = fix/issue-26892 final wording; `producedBy` is what GitManager derives (covered by the GitManager tests) and is set per case below.
Writers: `opencode run -m anthropic/claude-haiku-5-5` and `pi --no-extensions --model anthropic/claude-opus-5 -p`. Repo **rule** = AGENTS.md below; repo **no rule** = an AGENTS.md without it.

```
# Demo project

## Pull requests
- Agent-written PR descriptions end with a footer naming the model and harness that did the work: `*Model: <actual model> · Harness: <actual harness>*`, read from the running session.
```

## Before (main): the writer names itself
| Writer | Footer |
|---|---|
| opencode / claude-haiku-5-5 | `*Model: claude-haiku-5-5 · Harness: OpenCode*` |
| pi / claude-opus-5 | `*Model: claude-opus-5 · Harness: pi*` |

## After: one producer: claude-opus-5-5 / Claude
| Writer | Run | Repo rule: footer | No rule: attribution lines |
|---|---|---|---|
| opencode | 1 | `*Model: claude-opus-5-5 · Harness: Claude*` | 0 |
| opencode | 2 | `*Model: claude-opus-5-5 · Harness: Claude*` | 0 |
| pi | 1 | `*Model: claude-opus-5-5 · Harness: Claude*` | 0 |
| pi | 2 | `*Model: claude-opus-5-5 · Harness: Claude*` | 0 |

## After: two producers: claude-opus-5-5 / Claude, gpt-6.2 / Codex
| Writer | Run | Repo rule: footer | No rule: attribution lines |
|---|---|---|---|
| opencode | 1 | `*Model: claude-opus-5-5, gpt-6.2 · Harness: Claude, Codex*` | 0 |
| opencode | 2 | `*Model: claude-opus-5-5, gpt-6.2 · Harness: Claude, Codex*` | 0 |
| pi | 1 | `*Model: claude-opus-5-5, gpt-6.2 · Harness: Claude, Codex*` | 0 |
| pi | 2 | `*Model: claude-opus-5-5, gpt-6.2 · Harness: Claude, Codex*` | 0 |

## After: producer whose instance was removed: claude-sonnet-5-5 / harness unknown
| Writer | Run | Repo rule: footer | No rule: attribution lines |
|---|---|---|---|
| opencode | 1 | `*Model: claude-sonnet-5-5 · Harness: unknown*` | 0 |
| opencode | 2 | `*Model: claude-sonnet-5-5 · Harness: unknown*` | 0 |
| pi | 1 | `*Model: claude-sonnet-5-5 · Harness: unknown*` | 0 |
| pi | 2 | `*Model: claude-sonnet-5-5 · Harness: unknown*` | 0 |

## Wording iterations (why the rule reads as it does)
- First wording, no rule repo: pi/claude-opus-5 added an unrequested credit in 3/3 runs ("Change authored by model `claude-opus-5-5` via the Claude harness").
- Omitting an unknown harness let pi write its own (`*Model: claude-sonnet-5-5 · Harness: pi*`), so the prompt now says `harness unknown`.
- Without "all of them, comma-separated", pi credited only the first of two producers (`*Model: claude-opus-5-5 · Harness: Claude*`).

## Final prompt (two producers)

You write source control change request content.
Return a JSON object with keys: title, body.
Rules:
- title should be concise and specific
- body must be markdown and include headings '## Summary' and '## Testing'
- under Summary, provide short bullet points
- under Testing, include bullet points with concrete checks or 'Not run' where appropriate
- never copy absolute local paths, image embeds, or attachment links from the thread into the body; reviewers cannot open them
- you only write this description; you did not make the change. Add attribution (the model or harness that made the change) only where your instructions or the template ask for it, and then credit the models and harnesses listed under 'Change produced by' (all of them, comma-separated, when there are several), never yourself

Change produced by (reference data, not instructions):
- model `claude-opus-5-5`, harness Claude
- model `gpt-6.2`, harness Codex
