The surface-form file extension changes from .ailx to .ail. AILang's
authoring surface now uses the same .ail stem as its canonical JSON
form (.ail.json), giving the language a single coherent extension
family: .ail is the LLM-authored Form A, .ail.json is the canonical
JSON-AST Form B.
Scope (touched):
- 61 example renames examples/**/*.ailx → .ail (git mv)
- 1 rename experiments/.../rendered/ailx.md → ail.md
- 35 content-edited live-toolchain files (crates/, docs/DESIGN.md,
docs/roadmap.md, docs/PROSE_ROUNDTRIP.md, skills/, bench/reference/*.c,
experiment crates under experiments/.../{render,harness,master})
- Experiment-crate cohort rename Cohort::Ailx → Cohort::Ail,
Form::Ailx → Form::Ail, per_cohort/ailx → per_cohort/ail,
{form-only: ailx} → {form-only: ail}, ```ailx → ```ail
Out of scope (deliberately untouched, to preserve honest history):
- docs/journal-archive.md (content-frozen per CLAUDE.md)
- docs/journals/, docs/specs/, docs/plans/, bench/orchestrator-stats/
- experiments/.../runs/ (frozen LLM-output artefacts; models actually
saw .ailx — renaming would falsify the experimental record)
Verification: cargo build/test --workspace green; experiment crate
cargo test green; bench/check.py + compile_check.py + cross_lang.py
all 0-regressed; negative grep for ailx|Ailx|AILX outside the
out-of-scope paths returns zero matches.
Opens immediate follow-up: roadmap.md P2 todo `ail check`/build/run
accept .ail extension — after this rename, .ail is canonical
authoring surface but the CLI still produces a misleading JSON-parse
error on `ail check foo.ail`. That's the next iter.
All six existing agents (implementer, tester, architect, bencher,
docwriter, debugger) restructured into the same superpowers-derived
layout the SKILL.md files use: Iron Law, Carrier contract, Standing
reading list, Status protocol (DONE / DONE_WITH_CONCERNS /
NEEDS_CONTEXT / BLOCKED), Common Rationalisations, Red Flags. Agents
now know about docs/specs/<milestone>.md and docs/plans/<iteration>.md
but do not open them directly — context curation lives at the skill
level (controller hands the agent task_text, hypothesis, etc.).
Implementer carries TDD as an independent discipline layer, mirroring
the superpowers split between subagent-driven-development (outer loop)
and test-driven-development (inner loop). RED-first applies even when
a plan task forgot to script the failing test.
Debugger scope corrected: RED-first only, hands GREEN to implement
mini-mode. Previously the agent self-applied the fix, which
contradicted skills/debug/SKILL.md Phase 4. The skill is the source
of truth; the agent now matches it.
Two new named reviewer agents:
- ailang-spec-reviewer: did the diff match the task text?
- ailang-quality-reviewer: is the diff well-built? (only after spec
is compliant)
Both replace the ad-hoc general-purpose dispatch in skills/implement
Step 2.3 and 2.4. With named agents, AILang quality conventions are
amortised across dispatches instead of being re-stated inline per
prompt.
skills/implement/SKILL.md updated to dispatch the new reviewers.
skills/README.md agent roster expanded; conventions clarified to
state that agents do not open plan/spec files directly.
ailang-implementer/-tester -> skills/implement/agents/
ailang-architect/-bencher/-docwriter -> skills/audit/agents/
ailang-debugger -> skills/debug/agents/
agents/ now contains only README.md (rewritten in next commit as
roster of skill-bound agents).
