ducoterra 3bacbff874 fix(phased-execution): resume failed session on retry, surface errors, thinking/compaction indicators
- retries now resume the failed executor's session (pre/post session
  tracking replaces the broken mtime-vs-ref check)
- report recovery from the session file when the JSON stream loses its
  tail (child signaled mid-flush)
- progress.mjs: thinking indicators (◐ thinking… / ◑ thought for Ns),
  compaction (⧉ …) and provider auto-retry lines; trims trailing
  whitespace so no blank lines after LLM text; exits 1 on truncated
  stream, model error, or missing final text (pi --mode json always
  exits 0 even on errors)
- explicit ✗ ERROR lines + exit codes: 0 ok, 1 phase failed, 130/143
  interrupted (INT/TERM traps; post-pipeline check covers the case
  where bash suppresses the INT trap after a job dies from SIGINT)
- PIPESTATUS captured in a single statement (any following command
  resets it)
- skills dir: .gitignore README.md so pi's skill scanner (which honors
  .gitignore) stops warning 'description is required'

name: phased-execution
description: Runs the .agent/phases/ phased-execution pipeline (ported from opencode's next-phase/auto-phase commands). Use when the user asks to run the next phase, run all phases, run the phase pipeline, or check pipeline status. Each phase executes in a separate pi subprocess so this chat's context stays small.
---
# Phased Execution
Phase state lives in files, not chat:
- `.agent/PLAN.md` — master plan; LOCKED DECISIONS are binding
- `.agent/phases/todo/NN_name.md` — pending phases (alphanumerical sort = execution order)
- `.agent/phases/complete/` — finished phases
- `.agent/reports/` — per-phase executor reports, stderr, and validation logs
- `.agent/validate.sh` — the pass/fail gate for every phase
The scripts run each phase in a **separate pi process** (fresh context) with
bounded fixer retries. A phase only moves to `complete/` after the child exits
0, the child's stream ends with a clean final report, **and**
`.agent/validate.sh` passes. This chat only dispatches and relays results —
do not implement phase code yourself; that is what the subprocess is for.
## Live display
While a phase runs, `scripts/progress.mjs` relays the child's JSON stream to
the terminal: tool calls, assistant text, `◐ thinking…` / `◑ thought for Ns`
indicators, yellow `⧉ compacting context` lines (these can take minutes —
not a hang), and provider auto-retry notices. If the child dies mid-flush and
the stream loses the final message, the report is recovered from the
child's session file (`.agent/phase-sessions/`), so a completed phase is
never lost to a truncated stream.
## Commands
(Resolve `scripts/` against this skill's directory.)
Run the next phase, or a specific one:
```bash
bash scripts/run-phase.sh # first pending phase
bash scripts/run-phase.sh 03_api.md # specific phase (warns if out of order)
```
Run the whole pipeline — every pending phase, in order, stopping at the first
phase that fails after all retries:
```bash
bash scripts/auto-phase.sh
```
Re-running `auto-phase.sh` after a failure continues where it stopped.
## After a run
Exit codes: `0` = success (or nothing to run), `1` = phase failed after all
attempts / no pending phases error, `130`/`143` = interrupted (Ctrl+C / SIGTERM).
Failures always print a `✗ ERROR:` line with the last error output — if the
script's output looks like it ended abruptly, re-run it; the failed executor's
session is resumed automatically (retries continue the child's own session,
keeping its work).
Relay to the user: the phase name, its executor report (printed at the end of
the script output), and the validation outcome. On failure, point the user at
`.agent/reports/<phase>.a*.{md,err,validate}` — the script also prints a ready
to run `pi --session … -c “…”` command to continue the failed session manually.
## Configuration (environment variables)
| Var | Default | Meaning |
|-----|---------|---------|
| `MAX_FIX_ATTEMPTS` | `3` | Fixer retries per phase |
| `PHASE_MODEL` | session default | `--model` for child executors (e.g. `anthropic/claude-sonnet-4-5`) |
| `PHASE_THINKING` | session default | `--thinking` level for child executors |
| `PHASE_COMMIT` | `0` | `1` = `git commit --no-gpg-sign` after each passing phase |
| `PI_TRUST` | `0` | `1` = pass `--approve` (load project `.pi/` settings/skills into children) |
| `FRESH_FIX` | `0` | `1` = fixer retries start fresh instead of resuming the failed session |
| `QUIET` | `0` | `1` = suppress live progress display (reports are still written) |
## Setup notes
- First run creates `.agent/validate.sh` from `assets/validate.sh` if missing.
It must be adapted to the project's real checks — it is the authoritative
quality gate.
- Phase files are created by the `/to-phase`, `/audit-create`, `/new-project`,
and `/new-python-*` prompt templates.
- Child executor sessions are kept in `.agent/phase-sessions/`; add it to
`.gitignore` if the project is versioned.
- If you keep non-skill markdown (e.g. a `README.md`) in a skills directory
(like `~/.pi/agent/skills/`), pi warns “description is required” for it.
Add a `.gitignore` in that directory listing the file — pi's skill scanner
honors `.gitignore`, so the file is skipped.
