/agents fleet

Sub-agents are spawned via the Agent tool with subagent_type=<name>. Every non-trivial spawn forks its own git branch, writes a 6-file artefact bundle, and registers a row in kei-ledger (RULE 0.12).

tiers

T1 validators	6 read-only audit gates
T2 researchers	10 read-only analysis
T3 implementers	13 writes code/files
T5 orchestrators	8 hub-and-spoke

critic

Ruthless code critic finding anti-patterns, tech debt, security issues, bugs, and performance traps. Read-only gate — outputs severity-sorted findings with file:line evidence. No fixes, only reports.

critic-anti-pattern

Detects code anti-patterns: god classes, deep inheritance, shotgun surgery, primitive obsession. Read-only.

[AGENT] · T2 · researcherread-only

critic-bug

Detects bug patterns: off-by-one, error-swallowing, unchecked Result/Option, race conditions in shared state. Read-only.

[AGENT] · T2 · researcherread-only

critic-perf

Detects performance traps: N+1 queries, allocator hot loops, blocking-in-async, unbounded retention. Read-only.

[AGENT] · T2 · researcherread-only

critic-tech-debt

Detects dead code, TODO/FIXME, version-skew, abandoned branches, stale dependencies. Read-only.

ml-researcher

ML literature, benchmarks, reproducibility, and tooling-reuse research. Math-first + observable-classification discipline. Read-only. Use for any ML/RL question, paper review, sim/dataset selection, or before proposing a custom env / training loop.

[AGENT] · T2 · researcherread-only

researcher

Generic web + codebase research with 3 modes (web / code / hybrid). Returns Evidence-Graded findings. Read-only. Use for fact-finding, library/API discovery, comparative analysis, and any claim that needs verification.
