opencode-delegate

A coding-work delegation method that lets Codex plan and review a task while OpenCode performs the main implementation through a controlled command. It can route simpler or more involved jobs to suitable DeepSeek models.

In plain words
What is it for?
Use it to investigate code, trace behavior, implement features, refactor, migrate code, fix bugs, generate tests, and make repetitive or boilerplate edits.
Why use it?
It reduces the need for Codex to write every code change itself while keeping review, validation, and acceptance decisions with Codex. The controlled command also avoids using OpenCode directly.

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.

Security

Grade A, and why

opencode-delegate 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 yesterday.

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.

Safe OpenCode Delegate

Use this skill when the user wants Codex to orchestrate coding work while OpenCode performs the implementation inside the safe-claude sandbox.

Codex is the planner, operator, reviewer, and validator.

OpenCode is the implementer.

Run OpenCode only through:

safe-opencode run

Do not use plain opencode for delegated implementation.

Default stance

Do not write the main implementation yourself.

Use safe-opencode for:

  • finding relevant code
  • tracing behavior
  • implementation
  • refactors
  • migrations
  • bug fixes
  • test generation
  • repetitive edits
  • boilerplate
  • mechanical cleanup

Codex remains responsible for:

  • understanding the request
  • choosing scope
  • choosing the model
  • writing the OpenCode job
  • reviewing the diff
  • running validation
  • deciding whether the patch is acceptable

Model routing

Use the smallest useful DeepSeek model.

Fast path

Use DeepSeek v4 Flash for simple, bounded, low-risk jobs:

  • find where something is implemented
  • inspect a small area of the repo
  • explain a local behavior
  • make a one-file or very small edit
  • add a small test
  • fix an obvious typo, import, or error handling issue
  • triage a test failure
  • produce boilerplate inside an existing pattern
  • do a narrow rename or cleanup

Fast command:

safe-opencode run --model deepseek/deepseek-v4-flash --title "codex-delegate: <short-task-name>" "<single focused job>"

Pro path

Use DeepSeek v4 Pro for heavier work:

  • multi-file changes
  • architecture-sensitive changes
  • unclear bugs
  • migrations
  • public API changes
  • security-sensitive logic
  • database or persistence changes
  • complicated test failures
  • work where a bad patch would be costly to unwind

Pro command:

safe-opencode run --model deepseek/deepseek-v4-pro --title "codex-delegate: <short-task-name>" "<single focused job>"

If a Fast job returns a weak, broad, or confused patch, do not keep pushing it. Escalate once to Pro with a sharper prompt.

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.

opencode-delegate is a skill published in the GitHub repository sssemil/SKILLS (2 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 1,497 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.
