Cross-Agent Delegation

Claude Code orchestrates task routing to Kimi and Codex. The user interacts with Claude only — delegation happens behind the scenes.

---

Tool Detection

At session start, detect available tools:

command -v kimi &>/dev/null && HAS_KIMI=true || HAS_KIMI=false
command -v codex &>/dev/null && HAS_CODEX=true || HAS_CODEX=false

---

Codex Auto-Review (Stop Hook — Automatic)

When Codex is installed, a Stop hook reviews code after tests pass:

1. TDD loop check runs tests
2. codex-auto-review.sh runs Codex on the diff
3. Critical/High findings feed back to Claude (exit 2)
4. Clean reviews pass through (exit 0)

Fully automatic. No user or Claude action needed.

Kimi Delegation (Claude Orchestrates)

When Kimi is installed and the task complexity is bounded, Claude delegates directly — the user does not need to run anything.

Step 1: Score complexity, not file count

File count is a poor proxy for delegation risk. A 1-file change to an authz path is harder than a 12-file rename. Score the task on five dimensions, each 0-2, sourced from iCPG signals plus Claude's semantic reasoning:

Dimension	0 (low)	1 (medium)	2 (high)	Source
Cyclomatic / surface depth	<10 LOC, no branches	10-50 LOC, ≤3 branches	50+ LOC or nested control flow	iCPG query_graph over function bodies
Fan-out (consumer blast radius)	0-2 callers	3-10 callers	11+ callers	iCPG trace_path(<symbol>, mode=callers)
Crosses a security boundary (SEC-006, auth, PII, RLS, org-scope, billing, payments)	None	Tangential	Direct read or write	iCPG SEC-* / R-063 tags + grep for org_id, user_id, auth, pii
Concurrency / transactional	Pure / sync	Async only	Locks, transactions, atomic claims, FOR UPDATE, asyncio.Lock, session.begin	iCPG concurrency flags + grep
Domain invariants required	None / well-documented inline	Some implicit (need to read 1-2 files)	Heavy (cross-doc, ADR-bound, RFC-bound)	Claude reasoning + iCPG ADR linkage

# Auto-collect signals
icpg query blast <scope> --format json    # fan-out, async flags, sec tags
grep -rE "org_id|user_id|auth|pii"  <file>  # cheap sec heuristic if iCPG flags absent
grep -rE "asyncio.Lock|FOR UPDATE|session.begin" <file>  # concurrency heuristic

Step 2: Sum → routing

Total score	Route	Rationale
0-3	Kimi solo	Bounded surface, no security/concurrency/cross-doc concerns
4-6	Kimi → Codex auto-review (no user prompt)	Real risk, but not so high that we need full Claude context — Codex catches what Kimi might miss
7-10	Claude handles directly	Cross-cutting / security-critical / concurrency-heavy — needs full context

Step 3: Floor — trivial-case shortcut

To skip iCPG-query cost on truly trivial work:

# If <2 files changed AND no SEC/auth/PII/concurrency keyword in diff,
# → auto-Kimi without scoring.
FILES=$(git diff --name-only | wc -l)
HAS_RISK_KEYWORDS=$(git diff | grep -ciE "org_id|auth|pii|asyncio|FOR UPDATE|transaction|session\.begin" || true)
if [ "$FILES" -lt 2 ] && [ "$HAS_RISK_KEYWORDS" -eq 0 ]; then
  AUTO_KIMI=true
fi

This handles the trivial-rename / typo-fix case without paying the iCPG round-trip.

When NOT to Delegate (overrides scoring)

• User explicitly asked Claude to do it
• Cross-service changes (API + frontend + database) — needs full context regardless of score
• Production hotfix on a release branch — cross-tool review latency is too high
• Score 7+ in any single dimension (one critical axis is enough to keep Claude in the loop)

Step 4: Delegate via Bash

Claude writes a mnemos checkpoint, then runs Kimi headless:

# 1. Save current context to disk
mnemos checkpoint --force

# 2. Get context summary for Kimi
CONTEXT=$(mnemos resume 2>/dev/null)

# 3. Get constraints for target files
CONSTRAINTS=$(icpg query constraints <target-file> 2>/dev/null)

# 4. Run Kimi headless with full context
kimi --print -y -w . -p "
## Context (from mnemos checkpoint)
$CONTEXT

## Constraints (from iCPG)
$CONSTRAINTS

## Task
<specific task description>

## Rules
- Run tests after changes
- Record changes: icpg record --base main
- Write checkpoint when done: mnemos checkpoint --force
"

Step 4: Read Results

After Kimi finishes, Claude:

# Read what Kimi did
mnemos resume          # Kimi's checkpoint
icpg status            # Kimi's recorded symbols
git diff               # Kimi's file changes

When NOT to Delegate

• Security-sensitive code (auth, crypto, payments)
• Cross-service changes (API + frontend + database)
• Refactors that touch shared interfaces
• User explicitly asked Claude to do it

iCPG — Mandatory for All Agents

Before ANY code change, Claude runs these (and includes results when delegating):

Pre-Task Queries

# 1. Duplicate check — already done?
icpg query prior "<goal>"

# 2. Constraints — what invariants apply?
icpg query constraints <file-path>

# 3. Risk — is this symbol fragile?
icpg query risk <symbol-name>

After Code Changes

icpg record --reason <id> --base main
icpg drift check

---

Mnemos — Mandatory for All Agents

At Task Start

mnemos add goal "<task description>"

At Sub-Goal Boundaries

mnemos checkpoint

At Task End (auto-handled by Stop hook)

mnemos checkpoint --force

Context Transfer Between Tools

The checkpoint is the bridge. Claude writes it, Kimi reads it:

# Claude saves state
mnemos checkpoint --force

# Kimi (or Codex) reads state
mnemos resume

The checkpoint contains: goal, constraints, recent files, git state, fatigue level.
