From eeb041f002e79f6eb6c23f60d52967b054799b98 Mon Sep 17 00:00:00 2001 From: Bart van der Meeren Date: Fri, 2 Oct 2026 16:46:38 +0200 Subject: [PATCH 1/7] Add thread controls: settings, interrupt, approvals, and answers - threads set changes an existing thread's model, provider instance, reasoning effort, fast mode, other model options, permission, and plan mode; threads send takes the same flags and applies them before its turn. Values are checked against T3's provider catalog, which T3 serves over WebSocket RPC, and mapped to each model's option ids: Codex fast mode is serviceTier=priority, Claude's is fastMode. Changes follow T3 Code's composer order and are verified in the projection. The CLI refuses a permission change during a running turn, which T3 would kill, and a provider switch on a started thread, which T3 rejects. - Every sent turn carries the thread's model selection, which is how T3 applies a model or effort change to a live session. - threads interrupt, approve, decline, and answer act on a running turn and on pending approvals and questions, verify the provider's response, and can wait for the turn that follows. - models list prints providers, models, and their options. - Pending requests include questions that outlive their turn, the decisions an approval offers, and whether a request blocks a turn. - Turn ownership no longer guesses from the provider: a live Codex thread folded a mid-turn message into the running turn. A message stays with the turn it was sent into unless a turn without its own prompt starts within five seconds after that turn ends, and waits allow that window. - Proposed plans appear at every read detail level. - README and skill updates. --- README.md | 59 ++- skills/t3thread/SKILL.md | 57 ++- skills/t3thread/agents/openai.yaml | 2 +- skills/use-t3code-cli/SKILL.md | 21 + src/api.ts | 7 +- src/catalog.test.ts | 248 +++++++++++ src/catalog.ts | 295 +++++++++++++ src/cli.ts | 322 +++++++++++++-- src/modelSelection.ts | 86 ++++ src/service.ts | 168 ++------ src/threadApi.test.ts | 133 +++++- src/threadApi.ts | 101 ++++- src/threadControls.test.ts | 262 ++++++++++++ src/threadControls.ts | 643 +++++++++++++++++++++++++++++ src/threadSupport.ts | 60 +++ src/threads.test.ts | 256 +++++++++++- src/transcript.test.ts | 122 ++++-- src/transcript.ts | 181 +++++--- tests/cli.test.mjs | 24 ++ 19 files changed, 2743 insertions(+), 304 deletions(-) create mode 100644 src/catalog.test.ts create mode 100644 src/catalog.ts create mode 100644 src/modelSelection.ts create mode 100644 src/threadControls.test.ts create mode 100644 src/threadControls.ts create mode 100644 src/threadSupport.ts diff --git a/README.md b/README.md index 0aa1b0f..6cb3e1a 100644 --- a/README.md +++ b/README.md @@ -128,11 +128,13 @@ t3code --json threads read --thread - `answers`: the user's prompts and the turn's final answer. - `messages` (default): prompts and every assistant message, without reasoning summaries or tool calls. -- `full`: everything, including reasoning summaries, tool calls, changed files, and proposed plans. +- `full`: everything, including reasoning summaries, tool calls, and changed files. + +A plan-mode turn's proposed plan is its answer, so it appears at every level. `--turns ` keeps the last n turns, and `--last-turn` is short for `--turns 1`. `--first-turn` adds the first turn, which holds the original request. `--max-chars ` clips each message and tool entry but keeps its start and end.
