SubSaipen

SubSaipen

Read-only research agents that work in parallel. Extension, not Core (RFC SS 1.9).

Protocol

Each subSaipen lives in .saipen/extensions/subs/<name>/ with:

• STATE.md (own phase/task/next_action, mode: read-only)
• BOARD.md (own tickets: SUB-###)
• LOG.md (own event graph: S-###)
• kitchen/OUTBOX.md (findings for main agent)

Key rules:

• Read-only: never write to main project. Findings only via OUTBOX.
• One write path: main agent collects OUTBOX -> creates tickets -> works them.
• OUTBOX validated by tools/validate.py: needs status/summary/critical on ready.
• Patch support: a fixer-type sub (saipython) emits patches with base_head: + verified:.
• Backpressure (v7.98.0+): sub pauses own work if >10 ready entries pile up unreviewed.
• Boundary check on collect (v7.98.0+): main agent runs git status against whole tree before folding findings. A confused sub that wrote outside its folder gets caught.

Active sub-agents

Agent	Role	Status
saiwiki	Wiki maintainer	Scans project, detects drift from wiki, reports refresh needs. 3 OUTBOX cycles completed (WIKI-005 through WIKI-008); refresh W-025 closed. Every finding collected and ticketed.
saihunt	HUNT sweeper	Runs 6-category HUNT scan as parallel subagent
saitranslate	Translation builder	Builds locale packs (read-only limitation: cannot execute TRANSLATE phase). SAIT-002 collected and closed; all 32 locales + 3 root mirrors + 28 non-Core guides current at v7.155.0.
saipython	Python fixer	Fixer-type: finds type/error-handling issues, emits patches. Spawned, never run — 5 open tickets, 0 done. WARNs as never-run until first collection.

Spawning

> saipen sub spawn saiwiki
> saipen sub spawn saihunt
> saipen sub spawn saipython

A bare sub name — saiwiki, saihunt, saitranslate, anything sai* — is a role-adopt command: the agent spawns it if missing, becomes it, starts its own cycle. No second command needed. saipen sub sync refreshes the shared protocol files (PROTOCOL/README/crew/TEMPLATE) from the SAIPEN home without touching any sub's own history.

The main agent stays the single writer. Sub-agents research and report. No write races by construction.

Collecting OUTBOX

Main agent: reads <sub>/kitchen/OUTBOX.md
            validates entry (status: ready? has summary?)
            creates main-tree tickets from findings
            marks OUTBOX entry status: reviewed
            logs: RUN: collect <name>-### -> T-###

Write order is crash-safe: create the main ticket and append LOG line FIRST, then mark OUTBOX reviewed LAST. Duplicate on retry is safe; a lost finding is not.

Non-critical findings go to _shared/inbox.md for the next planning round; critical: true entries get ticketed immediately on the main board.

Key distinction: read-only scope vs capability (v7.111.0)

mode: read-only means two different things:

• Core read-only = capability lock: filesystem write unavailable, bans all 7 phases whose product is a file write (INIT, PLAN, ADD, BUILD, SHIP, CLEAN, TRANSLATE).
• SubSaipen read-only = scope lock: writes its own STATE/BOARD/LOG/kitchen freely, banned from shared tree. Only 4 phases banned (BUILD, SHIP, CLEAN, TRANSLATE). PLAN and ADD are reachable and expected — sub plans own backlog.

This means HUNT -> DONE is legal for a subSaipen (v7.111.0): a reporting sub's deliverable is its OUTBOX, the "add" step happens during main-agent collect. saihunt had been in that state truthfully since its first sweep.

Sub STATE.md now validated against Core's full rule set: 9th required field, transition legality, ISO-8601 updated, command vocabulary (v7.111.0).

Validation guards (v7.98.0+)

tools/validate.py enforces these subSaipen invariants on every invocation:

• Sub next_action format: every sub STATE.md next_action must follow RFC SS 1.2 prefix rules — WAIT: with category token, RESUME:, PHASE, or saipen command. Bare prose rejected.
• Self-transition enum check: if sub's transition_from equals its phase, the phase must be one of 16 known enum values.
• Adapter path existence: every saipen/ path in extensions/adapters/*.md must be a real file.
• Liveness check (v7.99.0): sub with open tickets, zero done, empty OUTBOX WARNs as never-run. ready entries WARN as findings waiting on collect.
• TEMPLATE validated (v7.101.0): the shipped TEMPLATE/STATE.md was previously exempted by name — hid a prefix-less next_action. Every spawned sub was born non-conformant. Fixed.
• Sub STATE parity (v7.111.0): sub STATE.md held to Core's rules — 9th required field, transition table, ISO-8601 updated, command vocabulary. Was previously checking a fraction.

saipython (fixer-type) also has:

• Capability gate: missing Python/pytest/ruff on host -> degrades to finding-only (saihunt-style), never fakes a verified: result.
• Scope discipline: one fix per patch, minimal diff. P2/P3 only — anything large or architectural goes to critical finding for the main agent.

"Под-агенты? Как бригада. Один ищет баги, второй чинит Python, третий переводит документацию. Главный агент собирает результаты и делает тикеты. Никто не мешает друг другу. Каждый в своей песочнице. И никаких 'я случайно переписал твой файл'. Потому что читать можно всем, писать — только одному."
