Claude Code categorically forbids subagents from spawning other
subagents (code.claude.com/docs/en/sub-agents and the Agent SDK
subagents page). The `or.1` architecture (and `pr.1` that ran on
top of it) presumed a named-exception for `ailang-implement-
orchestrator` to dispatch implementer / spec-reviewer / quality-
reviewer / tester per task. That exception never existed at the
platform level; the `Agent` tool was silently dropped from the
orchestrator-agent's tool set at dispatch time.
Architecture revised, doc-only:
- Per-task phases (implementer → spec-compliance check → quality
check) now run as sequential role-switches in the orchestrator-
agent's own context, not as nested subagents.
- The four role-files (implementer / spec-reviewer / quality-
reviewer / tester) become phase reference files the
orchestrator-agent consults at role-switch boundaries.
- Boss-context offload preserved; fresh-per-phase context given
up (the property that drove or.1's nested-dispatch design is
not buildable in Claude Code).
Files touched:
- skills/implement/agents/ailang-implement-orchestrator.md
(frontmatter, Iron Law, Phase 2/3 rewrite, rationalisations,
red flags)
- skills/implement/SKILL.md (frontmatter, Iron Law, sub-status
vocabulary note, cross-references)
- skills/README.md (Conventions: no more named exception; agent
roster: role-files recast as phase references)
- docs/journals/INDEX.md (or.2 entry appended)
- docs/journals/2026-05-11-iter-or.2.md (new — full rationale)
- docs/roadmap.md (P1 tool-wiring item removed; resolved as
categorically-not-fixable)
- docs/WhatsNew.md (user-facing correction entry appended)
No code changes; no bench impact; CLAUDE.md untouched (no stale
references to fix there).
Per-iter journal entry for the fieldtest run plus INDEX pointer.
Roadmap absorbs four actionable findings as P2/P3 todos (split the
merged BadCrossModuleTypeRef diagnostic, workspace subdir search,
`ail check` on `.ailx` extension, `.ailx` counterpart for the
canonical happy-path JSON exhibit). The two carry-on items
(`(import prelude)` doc-gap, the working ones) stay as notes in the
fieldtest spec only. P0 Floats milestone removed — closed
2026-05-10 and no longer load-bearing context.
No bug findings, so no debug dispatch. canonical-type-names is fully
shipped.
Anthropic now reserves /plan as a UI command, so the Skill tool refuses to
dispatch it. Rename the project's plan skill to planner, update the symlink
under .claude/skills/, and adjust references in CLAUDE.md, DESIGN.md,
skills/README.md, and the cross-references between brainstorm / implement /
audit / fieldtest / fieldtester. Plan files themselves (docs/plans/*.md)
keep their name — only the skill ID changes.
Three coupled changes to /implement:
- Boss-context offload via single subagent dispatch (target ~100x reduction)
- Iter isolation via branches (eliminates parallel-implementer conflicts)
- Per-iter journals under docs/journals/ replacing the JOURNAL.md monolith
JOURNAL.md becomes docs/journal-archive.md at acceptance time. Workers
stay at Opus 4.7; saving comes from token-volume relocation only.
Reversal of the language decision from 6d94fa5. Texts that get
committed to the repo permanently should follow the same English-
only rule as everything else; the Notify push stays 1:1 with the
WhatsNew entry, so both are English now.
The "only file intentionally not in English" carve-out in CLAUDE.md
is removed.
Done-state notifications now produce two synchronised outputs sharing
one text: an entry appended to docs/WhatsNew.md and the same string
sent via notify.sh. The text is written in German for the user-as-
reader who did not watch the session — no technical internals, no
iteration codes, lead with the change-in-the-project.
WhatsNew.md is the only file in the repo intentionally not in English;
the exception is documented in CLAUDE.md (Roles of docs/...) so a
future reader does not "correct" it back. Bounce-back notifications
stay Notify-only.
