MODE — Agent × Cognitive-Mode Matrix

Composable cognitive-mode blocks live in _blocks/mode-*.md. Any agent manifest can append them to its blocks = [...] list to stack the behavioural skew; modes compose (e.g. mode-skeptic + mode-minimalist = adversarial pruner).

This table is the suggested starting set per agent role. It is a guide, not a rule — pick what fits the agent's actual job.

Agent role	Recommended modes	Reason
critic	skeptic · devils-advocate	Doubt-first review; name the strongest objection before agreeing
validator	skeptic	Every claim needs an E1/E2 grade — no plausibility shortcuts
security-auditor	devils-advocate · skeptic	Steel-man the attacker; threat-model the worst case
researcher	skeptic	Cross-check every source; honest gaps over confident guesses
ml-researcher	skeptic · first-principles	Observable classification + invariant-derived priors
architect	first-principles · minimalist	Derive from constraints, prefer subtraction over addition
code-implementer	minimalist	Surgical edits; remove before adding
refactor specialist	minimalist	Delete dead code; prove every kept line
ml-implementer	minimalist · first-principles	Math-First — count params before code, derive over tune
brainstorm / concept-explorer	maximalist	Return 10× version + minimum bounds; user invokes exploration
physics-deriver	first-principles	Cite the invariant; no arguments from "best practice"

Intentionally unbiased roles (pick 0 modes by default):

• infra-implementer, modal-runner, fal-ai-runner, cost-guardian, most kei-<project>-specialist agents.

Modes are not free — each one lands verbatim in the prompt and consumes context. Stack only what you need.
