A workflow setting for choosing how Codex-driven work is shared between Codex and Claude, another AI coding assistant.

Use it to check the current work flow or explicitly switch between Codex-only review and Codex with Claude review.

It prevents unclear or invalid handoffs by showing the current setup and allowing only the supported flow choices.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add skills/gnayj/claude-code-sop/sop-flow

Any agent

npx skills add Gnayj/claude-code-sop --skill sop-flow

Clone the repo

git clone --depth 1 https://github.com/Gnayj/claude-code-sop

Made for: Claude Code, Codex.

Or install ccsop, the plugin that ships this one along with the rest of its 5 skills, 5 commands, 3 agents.

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	$0.00032	$0.00451
Opus 5	$0.00016	$0.00226
Sonnet 5	$0.00006	$0.00090
Haiku 4.5	$0.00003	$0.00045

Measured 5d ago against content hash 48682d13aa7b, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

sop-flow 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 5d ago.

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.

What it actually says

SOP Flow

Read references/contract.md.

Empty arguments or implicit activation are read-only: call ccsop_configure with action=status, then show the current owners/reviewers and the two legal Codex-driven choices.
Only explicit $sop-flow codex+codex or $sop-flow codex+claude may mutate.
Before mutation, call status and require contract_version=2 and observed_schema=1|2. Then call ccsop_configure with action=set-flow, expected_config_sha256=<status after_sha256>, and the requested flow.
If status reports config_valid=false, display its validation error and raw owners. A legal explicit set may repair the owner keys only when the resulting whole config validates; an unrelated error is a zero-write failure. Point to /sop-update or a verified .ccsop/backups/config/<sha256>.toml preimage, never a manual-edit fallback.
Reject claude+* and point to Claude /sop-flow.
For schema 1, report codex+claude as delivery=manual relay and offer /sop-update.
For schema 2, require the live tool catalog to contain claude_implement, report readiness/validation/apply policy from status, and explain that flow selection never enables the writer. The operator may opt in only outside the agent session by changing the generated enabled=false; this skill never performs or suggests an agent-side enable.
If implement ownership changes, display the server's safety_disable=true and the forced [implement.claude].enabled=false.
If the tool is missing, old, or the bridge was not restarted, make zero writes and tell the user to reconnect/restart /mcp. Never edit TOML or use a shell fallback.

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.

sop-flow is a skill published in the GitHub repository Gnayj/claude-code-sop (2 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 451 once invoked, about $0.0002 per session on Opus 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.
