This run fixed a recovery problem that operators could hit in the middle of an interactive build. A blocker prompt had been using the same choice for two different intentions: ask Gantry to investigate, or accept that the run should continue. The work separated those meanings, exposed a Proceed action in the terminal interface, and kept older clients able to answer with the retired token.
After that behavior was settled, the run completed the user-facing rename from Gantry Agent to Gantry Assistant. The result is still visible across the command parser, prompt catalog, terminal pane, generated reference data, and documentation, while compatibility paths remain where existing run state and overrides need them.
How this walkthrough is structured
Feature
What did the run build and ship?
Interactive blockers now offer investigation launchers separately from resolving Proceed and Stop answers, and the current assistant name is the public spelling across commands, prompts, reference data, and documentation.
Build
How did Gantry structure the work?
The run was cut into a blocker-continuation milestone and a naming-compatibility milestone, with clean sprint execution and review gates used to prove each boundary before the next surface depended on it.
Milestone 1
Clear The Blocker
2 tasks 6 agents 26m 33s wall time 168k peak context
The current code still treats a blocked run as waiting on a typed choice rather than an overloaded freeform intention. Investigation through Gantry, external harnesses, or a shell stays non-resolving, while Proceed and Stop answer the original prompt. The same token parser also accepts the older Gantry-choice spelling as Proceed, so recorded or attached clients are not orphaned by the split.
This milestone carried the recovery behavior as its own product slice. The brief was broad, but it split cleanly into a shared choice contract followed by the terminal action that consumed it. That made the first child sprint the semantic foundation and the second child sprint the interface work. The run record shows the nested work stayed within that cut, with review followed by another gate before the milestone was accepted.
Blocker Choice Split
2 agents 14m 14s wall time 168k peak context
The domain model now has explicit blocker choices for harness investigation, Gantry investigation, shell access, Proceed, and Stop. Choice generation emits launchers before the resolving answers, and parsing maps the retired Gantry token to the Proceed behavior without offering it as a new button. The reference vocabulary exports the same token set, so documentation and clients read the contract from the product rather than from a stale prose table.
This sprint was asked to define the contract before any front end rendered it. That was a good memoryless unit because it lived at the boundary between domain tokens, prompt construction, compatibility parsing, and merge fallback behavior. The tests it added or adjusted were focused on the mapping risk: which choices are launchers, which ones answer, and which retired token still resolves. Its gate ran cleanly, so later work could build against a stable choice set.
TUI Proceed Action
1 agents 2m 7s wall time 30k peak context
The TUI now renders a Proceed button for inline blocker prompts and sends that choice as the pending prompt answer. Gantry investigation still focuses the assistant pane and seeds context without resolving the prompt, and shell or external harness choices remain launchers. The same state code marks answered blocker prompts unanswerable locally, so a visible action cannot be reused after the original prompt has moved on.
This sprint consumed the new contract at the terminal surface. Its scope was intentionally local: render the new action, route activation through the existing answer channel, clear local prompt state, and leave investigation as a pivot into the assistant composer. Because the underlying tokens were already established, the agent could focus on keyboard, mouse, and prompt identity behavior. The sprint passed without a repair loop.
Milestone 2
Rename Assistant
2 tasks 7 agents 28m 45s wall time 166k peak context
Gantry now presents the built-in conversational surface as the Gantry Assistant across active product language. The older Agent phrasing remains only where it is historical, a documented compatibility alias, or a stable storage name. That makes the current interface coherent without pretending that older run artifacts and override paths never existed.
This milestone handled the naming migration only after the blocker work had landed. The decomposition separated executable compatibility from the larger prose and reference sweep, which kept the risky part small: command aliases and prompt lookup had to keep older operators working before current wording could be made canonical. Both child sprints ran through review and a follow-up gate, and no replan or recovery was recorded.
Command Prompt Compatibility
2 agents 13m 17s wall time 166k peak context
The command surface now treats the assistant spelling as current while keeping the old singular command as a legacy diagnostic alias. The bundled mission prompt lives under the assistant stem, and configuration loading still falls back to an old-stem override when no assistant-stem override exists. Current docs describe that fallback, and tests protect it as behavior rather than as a wording count.
This sprint carried the compatibility core of the rename. It was bounded around behavior rather than wording volume: the public diagnostic command, legacy command acceptance, bundled prompt identity, and prompt override fallback all had to agree. The fresh agent could test those paths without sweeping every document at the same time. Review did not force a remaining-plan change, but the post-review gate still exercised the boundary again.
User-Facing Sweep
2 agents 7m 45s wall time 140k peak context
The live tree uses Gantry Assistant in the TUI labels, command help, assistant documentation, prompt inventory, harness documentation, usage fixtures, and generated reference data. The reference exporter output in the Rails data copy matches the root vocabulary source, so the website sees the same names as the binary. Historical plan material and compatibility-sensitive directories still retain the older spelling where the product intentionally preserves it.
This sprint was the broad finishing pass, so it came after compatibility had an executable contract. Its brief covered interface text, help output, documentation, prompt catalogs, generated reference artifacts, and Rails-served copies while leaving historical records and storage identifiers coherent. That is a wide surface, but it was mostly propagation of an already proven naming rule. The review and final gate completed cleanly.
