Three polish items from post-audit parallel agent.
1. Dynamic schema whitelist (drops hardcoded const drift)
_assembler/src/schemas_export.rs (NEW, 136 LOC) — loader cube,
priority path $AGENT_ROOT/artifacts/schemas.json →
~/.claude/agents/artifacts/schemas.json → BUILTIN fallback.
Hand-rolled JSON parser (no serde_json dep).
_assembler/src/validator.rs delegates to schemas_export::load,
keeps KNOWN_ARTIFACT_SCHEMAS alias for back-compat.
_primitives/_rust/kei-artifact/src/export.rs (NEW, 82 LOC) —
write() + render() + default_path().
_primitives/_rust/kei-artifact/src/cli_cmds.rs (NEW, 126 LOC) —
extracted cmd_emit/get/list/chain so main stays <200 LOC.
ExportSchemas + ListSchemas subcommands; cmd_register
auto-refreshes export file (best-effort).
2. KNOWN_SCHEMAS SSoT — documented-dual-const + drift-test
(Option "simpler than new crate"). SSoT in kei-artifact's
BUILTIN; schemas_export::BUILTIN is a documented mirror;
builtin_schemas_do_not_drift_from_kei_artifact test in
validator.rs parses the primitive's source at test time and
diffs. <30 LOC change. No workspace structural change —
assembler stays decoupled from runtime primitive.
3. Agent-to-mode matrix + wizard Phase 3.6
_blocks/mode-matrix.md (NEW, 24 LOC) — 11-row table mapping
agent role × recommended mode blocks.
skills/new-agent/SKILL.md — new Phase 3.6 (between name-confirm
3.5 and manifest-write 4). AskUserQuestion with 5
cognitive-mode options (skeptic/devils-advocate/minimalist/
maximalist/first-principles, multiSelect). Appends picked
labels to manifest's blocks array. Defaults to NONE.
_blocks/README.md adds one-line reference to the matrix.
_assembler/tests/mode_blocks.rs (NEW, 78 LOC) — 3 integration
tests lock the wiring.
README.md — all accumulated count + pre-built-binaries + plugin
section edits from the v0.16 cycle consolidated here (will be
replaced by markers in v0.17 counts-autogen refactor).
Tests: assembler 24 → 33 (+9), kei-artifact 24 → 31 (+7), total
48 → 64. cargo check --workspace clean.
Constructor Pattern: largest new file validator.rs 180 LOC.
Pre-existing flagged for separate refactor: kei-artifact
validate.rs 268 LOC (not touched by this polish).

_blocks/ — Composable Agent Content
Each .md file in this directory is a block: a single-concern, standalone-readable snippet that any agent manifest can include via its blocks = [...] list. The _assembler concatenates selected blocks + manifest metadata into the final agent .md that Claude Code loads.
Blocks are grouped by prefix:
| Prefix | Purpose |
|---|---|
baseline, evidence-grading, memory-protocol |
Obligatory base — every manifest must include these |
rule-* |
Discipline rules (pre-dev-gate, test-first, error-budget, double-audit, math-first) |
mode-* |
Cognitive mode blocks (see below) |
stack-* |
Language / framework constraints (Rust Axum, React Vite, Swift SPM, …) |
deploy-* |
Deployment target rules (Modal, AWS EC2, Cloudflare, Hetzner, …) |
api-* |
External API conventions (Apify, fal.ai, ElevenLabs, Anthropic, …) |
db-* |
Database rules (Postgres, SQLite, Drizzle, sqlx, migrations) |
auth-*, security-*, obs-*, ci-*, test-*, scraper-*, domain-*, docs-* |
Domain-specific rules |
Cognitive mode blocks
Composable behavioural skews. Add any combination to a manifest's blocks list to stack the mode. Modes compose — e.g. mode-skeptic + mode-minimalist yields an adversarial pruner.
| Block | Purpose |
|---|---|
mode-skeptic.md |
Doubt the conclusion until proved; flag claims without E1/E2 grade |
mode-devils-advocate.md |
Steel-man the opposite; name the strongest objection before agreeing |
mode-minimalist.md |
Prefer deleting over adding; justify every addition against existing code |
mode-maximalist.md |
Explore 10× scope; return both maximum and minimum bounds; only when user invokes exploration |
mode-first-principles.md |
Derive from invariants; cite the physical / mathematical constraint, not "best practice" |
See mode-matrix.md for the agent-role × recommended-modes table used by the skills/new-agent wizard (Phase 3.6). It is the suggested starting set per role — modes remain a free pick per manifest.
Adding a new block
- Pick a stable prefix (existing category or a new one documented here).
- One concern per file. 20–50 LOC target,
<200 LOChard cap (Constructor Pattern). - Imperative voice (
"Do X"not"the agent should do X") — these land verbatim in agent prompts. - Standalone-readable — do not assume sibling blocks are present. Cross-references OK, hard dependencies not.
- Reference from a manifest's
blocks = [...]list; the assembler validates existence.
Ownership
Blocks are kit-owned — install.sh overwrites _blocks/ on re-run, backing up local edits to _blocks.bak-TIMESTAMP/. User-owned content belongs in _manifests/*.toml (which are never overwritten).
