"""Trellis per-turn breadcrumb hook (UserPromptSubmit / BeforeAgent equivalent).
|
|
|
|
Runs on every user prompt. Resolves the active task through Trellis'
|
|
session-aware active task resolver and emits a short <workflow-state>
|
|
block reminding the main AI what task is active and its expected flow.
|
|
|
|
The emitted ``hookEventName`` field is platform-aware: most hosts expect
|
|
``UserPromptSubmit`` (Claude Code naming, also accepted by Cursor / Qoder /
|
|
CodeBuddy / Droid / Codex / Copilot wiring), but Gemini CLI 0.40.x renamed
|
|
its per-turn event to ``BeforeAgent`` and its schema validator rejects the
|
|
legacy name. ``_detect_platform`` picks the right value at runtime.
|
|
Breadcrumb text is pulled exclusively from workflow.md
|
|
[workflow-state:STATUS] tag blocks — workflow.md is the single source of
|
|
truth. There are no fallback dicts in this script: when workflow.md is
|
|
missing or a tag is absent, the breadcrumb degrades to a generic
|
|
"Refer to workflow.md for current step." line so users see (and fix)
|
|
the broken state instead of the hook silently masking it.
|
|
|
|
Shared across all hook-capable platforms (Claude, Cursor, Codex, Qoder,
|
|
CodeBuddy, Droid, Gemini, Copilot). Kiro is not wired (no per-turn
|
|
hook entry point). Written to each platform's hooks directory via
|
|
writeSharedHooks() at init time.
|
|
|
|
Silent exit 0 cases (no output):
|
|
- No .trellis/ directory found (not a Trellis project)
|
|
- task.json malformed or missing status
