A local handoff tool that sends one bounded coding request to another installed Claude Code or Codex command-line agent. It can ask that agent to implement a scoped change or give a read-only second opinion.

Use it to delegate a small implementation or request another agent’s review of code and decisions.

It lets you use a second local coding agent without losing control of the task or accepting unverified results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.00682
Opus 5.5	$0.00023	$0.00273
Sonnet 5.5	$0.00012	$0.00136
Haiku 4.5	$0.00006	$0.00068

Security

Grade A, and why

cccc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/cccc-common.sh, scripts/consult.sh, scripts/delegate.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cccc

Route one bounded request to the other installed local CLI. delegate permits scoped implementation; consult requests a read-only second opinion. The orchestrator validates the result and makes no unverified capability claim.

1. Authorization gate

An explicit request naming cccc/4C, this wrapper, or a handoff to the installed local Claude Code or Codex peer authorizes that path within the user's scope.
Bare delegate or consult terms are not launch authorization; treat them as a heuristic until the user confirms the local peer handoff.
For a heuristic match, only suggest cccc. Confirm with the user before any external CLI launch.
If user or project instructions prohibit external agents, do not launch a wrapper.

Discovery of this skill is not launch authorization. Apply this gate again immediately before invoking a wrapper.

2. Routing precedence

Use this order exactly:

user instruction > project rules > verified local capability > heuristic

The Codex orchestrator targets Claude; the Claude Code orchestrator targets Codex. Never target itself or infer identity from executable availability.

3. Choose one channel

Need	Channel	Result
Bounded repository implementation with explicit editable paths	`delegate`	Peer changes plus a report and audit log
Analysis, critique, or decision support without repository edits	`consult`	Peer opinion plus an audit log

Do not use consult as authorization to implement its recommendation. Do not use delegate when the user asked only for analysis.

4. Verify capability

Verify the selected CLI and authentication before launch. Follow setup when a check fails.

For raster images, verify usable Codex $imagegen capability first. Do not promise image generation, a model, effort, cost, or network path.

5. Safety invariants

Use only the canonical wrappers in this skill. Never construct a looser raw CLI fallback.
Treat wrapper exit status 0 as the success authority; an existing report or opinion alone is not success.
DELEGATE_DEPTH and wrapper prompts guard against accidental peer recursion; do not ask the peer to invoke another agent.
Tool restrictions limit exposed operations. The post-run Git audit detects Git-visible changes; neither control is an OS sandbox. Use external isolation for an untrusted repository.
The peer must not alter repository history, hide working state, discard files, publish changes, or broaden the requested scope.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cccc is a skill published in the GitHub repository JTropy/cccc-skill (14 stars, last pushed 3mo ago), licensed MIT. It adds 58 tokens to every session and 682 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
