# Predictor Agent
|
|
|
|
|
|
|
|
|
|
**Role**: Infrastructure pattern detection (the "goblin"). Runs a 3-step
|
|
|
|
|
formula (preflight → collect-signals → analyze-and-predict) via interactive
|
|
|
|
|
tmux Claude session (sonnet). Collects disinto-specific signals: CI pipeline
|
|
|
|
|
trends (Woodpecker), stale issues, agent health (tmux sessions + logs), and
|
|
|
|
|
resource patterns (RAM, disk, load, containers). Files up to 5
|
|
|
|
|
`prediction/unreviewed` issues for the Planner to triage. The predictor MUST
|
|
|
|
|
NOT emit feature work — only observations about CI health, issue staleness,
|
|
|
|
|
agent status, and system conditions.
|
|
|
|
|
|
|
|
|
|
**Trigger**: `predictor-run.sh` runs daily at 06:00 UTC via cron (1h before
|
|
|
|
|
the planner at 07:00). Guarded by PID lock (`/tmp/predictor-run.lock`) and
|
|
|
|
|
memory check (skips if available RAM < 2000 MB).
|
|
|
|
|
|
|
|
|
|
**Key files**:
|
|
|
|
|
- `predictor/predictor-run.sh` — Cron wrapper + orchestrator: lock, memory guard,
|
|
|
|
|
sources disinto project config, builds prompt with formula + Codeberg API
|
|
|
|
|
reference, creates tmux session (sonnet), monitors phase file, handles crash
|
|
|
|
|
recovery via `run_formula_and_monitor`
|
|
|
|
|
- `formulas/run-predictor.toml` — Execution spec: three steps (preflight,
|
|
|
|
|
collect-signals, analyze-and-predict) with `needs` dependencies. Claude
|
|
|
|
|
collects signals and files prediction issues in a single interactive session
|
|
|
|
|
|
|
|
|
|
**Supersedes**: The legacy predictor (`planner/prediction-poll.sh` +
|
|
|
|
|
`planner/prediction-agent.sh`) used `claude -p` one-shot, read `evidence/`
|
|
|
|
|
JSON, and ran hourly. This formula-based predictor replaces it with direct
|
|
|
|
|
CI/issues/logs signal collection and interactive Claude sessions, matching the
|
|
|
|
|
planner's tmux+formula pattern.
|
|
|
|
|
|
|
|
|
|
**Environment variables consumed**:
|
|
|
|
|
- `CODEBERG_TOKEN`, `CODEBERG_REPO`, `CODEBERG_API`, `PROJECT_NAME`, `PROJECT_REPO_ROOT`
|
|
|
|
|
- `PRIMARY_BRANCH`, `CLAUDE_MODEL` (set to sonnet by predictor-run.sh)
|
|
|
|
|
- `WOODPECKER_TOKEN`, `WOODPECKER_SERVER` — CI pipeline trend queries (optional; skipped if unset)
|
|
|
|
|
- `MATRIX_TOKEN`, `MATRIX_ROOM_ID`, `MATRIX_HOMESERVER` — Notifications (optional)
|
|
|
|
|
|
|
|
|
|
**Lifecycle**: predictor-run.sh (daily 06:00 cron) → lock + memory guard →
|
|
|
|
|
load formula + context → create tmux session → Claude collects signals
|
|
|
|
|
(CI trends, stale issues, agent health, resources) → dedup against existing
|
|
|
|
|
open predictions → file `prediction/unreviewed` issues → `PHASE:done`.
|
|
|
|
|
The planner's Phase 1 later triages these predictions.
