# Trellis Configuration
# Project-level settings for the Trellis workflow system
#
# All values have sensible defaults. Only override what you need.

#-------------------------------------------------------------------------------
# Session Recording
#-------------------------------------------------------------------------------

# Commit message used when auto-committing journal/index changes
# after running add_session.py
session_commit_message: "chore: record journal"

# Maximum lines per journal file before rotating to a new one
max_journal_lines: 2000

#-------------------------------------------------------------------------------
# Session Auto-Commit
#-------------------------------------------------------------------------------

# Auto-commit behavior for session journal + task archive operations.
# - true (default): scripts auto-stage and auto-commit journal / task changes
#   after add_session.py / task.py archive runs.
# - false: scripts do not touch git. Files (journal-*.md, task archive moves)
#   are still written to disk; you decide whether to git add / commit.
#
# Use `false` if your project's .gitignore intentionally excludes `.trellis/`
# and you want session data kept local-only, or if you prefer to review
# staged changes manually before each commit.
#
# Accepts: true / false / yes / no / 1 / 0 / on / off (case-insensitive).
#
# session_auto_commit: true

#-------------------------------------------------------------------------------
# Task Lifecycle Hooks
#-------------------------------------------------------------------------------

# Shell commands to run after task lifecycle events.
# Each hook receives TASK_JSON_PATH environment variable pointing to task.json.
# Hook failures print a warning but do not block the main operation.
#
# hooks:
#   after_create:
#     - "echo 'Task created'"
#   after_start:
#     - "echo 'Task started'"
#   after_finish:
#     - "echo 'Task finished'"
#   after_archive:
#     - "echo 'Task archived'"

#-------------------------------------------------------------------------------
# Monorepo / Packages
#-------------------------------------------------------------------------------

# Declare packages for monorepo projects.
# Trellis auto-detects workspaces during `trellis init`, but you can also
# configure them manually here.
#
# packages:
#   frontend:
#     path: packages/frontend
#   backend:
#     path: packages/backend
#   docs:
#     path: docs-site
#     type: submodule
#   # For polyrepo / meta-repo layouts (independent .git in each subdir),
#   # mark the package with `git: true`. The runtime treats it as an
#   # independent repository for things like git-context display.
#   webapp:
#     path: ./webapp
#     git: true

# Default package used when --package is not specified.
# default_package: frontend

#-------------------------------------------------------------------------------
# Default workflow
#-------------------------------------------------------------------------------
# Team-shared default workflow for tasks that do not pin one. The id names a
# variant file in `.trellis/workflows/<id>.md` (populate it with
# `trellis workflow --save <id>`). This value is committed, so the whole team
# shares the same default. A per-developer override lives in the gitignored
# `.developer` file as a `workflow=<id>` line and takes precedence over this.
#
# Resolution precedence: per-task (task.json `workflow`) > personal
# (`.developer` `workflow=`) > this `default_workflow` > global
# `.trellis/workflow.md`.
#
# default_workflow: native

#-------------------------------------------------------------------------------
# Channel worker OOM guard
#-------------------------------------------------------------------------------
# Default safeguards for `trellis channel spawn` workers. The guard runs
# at spawn time (cleans expired idle workers, then enforces the live-worker
# budget) and inside each supervisor (self-terminates a worker that stays
# continuously idle past `idle_timeout`).
#
# Precedence: CLI flag > env var (TRELLIS_CHANNEL_WORKER_IDLE_TIMEOUT /
# TRELLIS_CHANNEL_MAX_LIVE_WORKERS) > this config > built-in default.
#
# `idle_timeout: 0` disables idle cleanup (workers can sit idle forever
# unless explicitly killed or given `--timeout`).
# `max_live_workers: 0` disables the spawn-time budget check.
#
# `trusted_context_dirs` extends the `--file`/`--jsonl`/`--agent` containment
# check beyond the worker cwd — useful when `.trellis/tasks` or
# `.trellis/workspace` is a symlink to an external directory. Realpaths under
# any listed dir are accepted in addition to cwd.
# `auto_trust_trellis_symlinks: false` disables the narrow auto-trust of
# `.trellis/tasks` / `.trellis/workspace` when either is itself a top-level
# symlink (auto-trust is on by default).
#
channel:
  worker_guard:
    idle_timeout: 5m
    max_live_workers: 6
  # trusted_context_dirs:
  #   - /work/user/trellis_workspace
  # auto_trust_trellis_symlinks: false

#-------------------------------------------------------------------------------
# Codex (dispatch behavior)
#-------------------------------------------------------------------------------
# Codex-only knob; other platforms ignore it. Default ("auto") dispatches
# trellis-implement / trellis-check / trellis-research sub-agents. This does
# not rely on inherited parent transcripts: `fork_turns` remains
# caller-controlled, while Codex's native SubagentStart hook injects task
# context when trusted and child-side loading remains the fallback when it is
# unavailable. Set to "inline" only to keep implementation and checks in the
# main session. "sub-agent" remains a backwards-compatible alias for "auto".
# Invalid explicit values safely use inline mode.
#
# In "auto" mode, dispatched sub-agents inherit the main session's model
# unless you pin one. To use a cheaper/faster model for implement/check/
# research sub-agent work, edit `model` / `model_reasoning_effort` directly
# on the generated `.codex/agents/trellis-*.toml` files (see the commented
# hint lines in those files) — there is no config.yaml knob for this,
# `trellis update` preserves your edits across regeneration.
#
# codex:
#   dispatch_mode: auto  # or "inline"; legacy alias: "sub-agent"

#-------------------------------------------------------------------------------
# Sub-agent context injection limits
#-------------------------------------------------------------------------------
# Caps how much task context (implement.jsonl / check.jsonl referenced files,
# plus prd.md / design.md / implement.md) gets inlined into a sub-agent's
# first prompt. Oversized files are truncated with a notice; once the total
# payload cap is reached, remaining files degrade to index lines (path +
# reason + size) instead of being inlined.
#
# All values are byte counts. `0` disables the corresponding limit.
#
# context_injection:
#   max_file_bytes: 32768        # per implement.jsonl / check.jsonl referenced file
#   max_artifact_bytes: 65536    # per task artifact (prd.md / design.md / implement.md)
#   max_total_bytes: 131072      # whole injected payload; overflow degrades to index lines

#-------------------------------------------------------------------------------
# Path-scoped spec injection
#-------------------------------------------------------------------------------
# When the agent touches a file (Read/Edit/Write/MultiEdit), spec .md files
# under .trellis/spec/ whose frontmatter `paths:` globs match the touched path
# are surfaced into the session right then. The first time a spec matches it is
# injected in full; while its content is unchanged and the refresh window has
# not elapsed it stays silent; once the window elapses a short `<spec-ticket>`
# reminder is emitted to counter recency decay. Editing the spec itself — or a
# SessionStart after /clear or /compact — re-injects the full text.
# Oversized specs are truncated with a notice; once the per-event payload cap
# is reached, remaining full bodies degrade to index lines (path + description)
# instead of being inlined.
#
# Character values: the ceiling this budget respects is Claude Code's
# documented 10,000-CHARACTER additionalContext limit, so the caps count
# characters too (byte caps made CJK specs pay 3x for the same text).
# `0` disables the corresponding limit.
# The refresh window uses wall-clock seconds. `0` disables time-based reminders;
# SessionStart resets after /clear or /compact still force a full re-injection.
#
# spec_injection:
#   enabled: true                 # false disables injection entirely
#   max_spec_chars: 9400          # per matched spec file
#   max_total_chars: 9500         # whole per-event payload; overflow degrades to index lines
#   refresh_window_seconds: 2700  # touches past this interval re-emit a ticket
#   tools:                        # tool events that trigger injection
#     - Read
#     - Edit
#     - Write
#     - MultiEdit

#-------------------------------------------------------------------------------
# Per-turn prompt injection
#-------------------------------------------------------------------------------
# Escape hatch for the per-turn <workflow-state> breadcrumb. When a user
# prompt contains the skip keyword as a standalone word (case-insensitive,
# word-boundary match — "no-trellisfoo" does NOT count), the breadcrumb is
# skipped for that turn only. Does not affect SessionStart or sub-agent
# context injection.
#
# prompt_injection:
#   skip_keyword: "no-trellis"   # "" disables the escape hatch entirely
