# Workflows
Use these patterns by intent. Prefer durable channels for multi-round work and
`channel run` for one-shot questions.
## Pattern A: Multi-round Brainstorm
Use when the user says "和 codex/claude 讨论一下", "brainstorm", or "拉一个 agent
进来一起看".
```bash
trellis channel create brainstorm-storage-layer --by main \
--task .trellis/tasks/05-XX-storage-adapter
trellis channel spawn brainstorm-storage-layer \
--agent architect --provider codex \
--file .trellis/tasks/05-XX-storage-adapter/prd.md \
--file .trellis/tasks/05-XX-storage-adapter/design.md \
--as cx-arch --timeout 30m
trellis channel send brainstorm-storage-layer \
--as main --to cx-arch --text-file /tmp/brainstorm-r1.md
trellis channel wait brainstorm-storage-layer \
--as main --kind done --from cx-arch --timeout 10m
```
Do not stop after one answer. Read the answer, identify vague areas, send a
new probe, and repeat until the result is executable.
Minimum round structure:
1. Direction split: should this live in an existing mechanism or a new one?
2. MVP boundary: v1, v2, and what would force v2 back into v1.
3. Data contract: events, schema, metadata, state source of truth, compatibility.
4. CLI / UX contract: command names, flags, errors, defaults, ambiguity.
5. Cross-layer risk and tests: shared helpers, drift points, release-blocking tests.
Optional rounds:
- Operations: logs, debugging, stuck workers, kill/restart, recovery.
- Migration/release: breaking status, manifest, changelog, docs-site.
- Opposition review: ask the peer agent to argue against the current plan.
Every probe should request concrete file paths, commands, schema, rejected
alternatives, and release-blocking issues. Reject hedging when a decision is
needed.
## Pattern B: Implement / Check Agent
Use when the user asks to dispatch implementation or review work.
```bash
TASK=.trellis/tasks/05-12-foo
trellis channel create cr-foo --task "$TASK" --by main
trellis channel spawn cr-foo \
--agent check \
--jsonl "$TASK/check.jsonl" \
--file "$TASK/prd.md" \
--file "$TASK/design.md" \
--file "$TASK/implement.md" \
--cwd "$PWD" --timeout 15m
trellis channel send cr-foo --as main --to check --text-file /tmp/cr-brief.md
trellis channel wait cr-foo --as main --kind done --from check --timeout 15m
trellis channel messages cr-foo --kind message --from check --tag final_answer
```
For implement work, use `--agent implement` and send an implementation brief.
For check work, include the exact diff scope, relevant specs, and validation
already run.
## Pattern C: Parallel Reviewers
Use one channel and distinct worker names.
```bash
trellis channel create cr-feature --by main --ephemeral
trellis channel spawn cr-feature --agent check \
--jsonl "$TASK/check.jsonl" --file "$TASK/prd.md" --file "$TASK/design.md" \
--timeout 15m
trellis channel spawn cr-feature --agent check --provider codex --as check-cx \
--jsonl "$TASK/check.jsonl" --file "$TASK/prd.md" --file "$TASK/design.md" \
--timeout 15m
trellis channel send cr-feature --as main --to check --text-file /tmp/cr-brief.md
trellis channel send cr-feature --as main --to check-cx --text-file /tmp/cr-brief.md
trellis channel wait cr-feature --as main --kind done --from check,check-cx --all --timeout 15m
```
`--all` means every listed worker must emit a matching event.
## Pattern D: One-shot Worker
```bash
trellis channel run --provider codex --message "say hi in 3 words" --timeout 1m
trellis channel run --agent plan --message-file /tmp/plan-question.md --timeout 10m
```
On success, `run` removes the ephemeral channel. On error/timeout/killed, it
keeps the channel and prints the path for inspection.
## Pattern E: Forum Channel
Use for issue forums, topic-style feedback, release todos, agent findings, and
internal changelogs. Read `forum.md` for the full model.
## Pattern F: Take Over Existing Thread
If the user gives a forum/thread name, restore context yourself:
```bash
trellis channel forum <board> --scope global
trellis channel thread <board> <thread> --scope global --raw
trellis channel context list <board> --scope global --thread <thread>
trellis channel messages <board> --scope global --raw --thread <thread>
```
Output a constraint summary, not a transcript dump:
- user-level problem
- context files that affect this repo
- current-version versus future-version requirements
- whether current code/design satisfies it
- next action or comment to append
