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.

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 | $0.00042 | $0.03789 |
| Opus 5 | $0.00021 | $0.01895 |
| Sonnet 5 | $0.00008 | $0.00758 |
| Haiku 4.5 | $0.00004 | $0.00379 |
Grade A, and why
opencode-sync 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
opencode-sync
Keeps one canonical source of truth (skills, agents, commands, MCP config, rules files) usable on BOTH Claude Code and OpenCode. Skills and rules are single-source by design (OpenCode reads .claude/skills/ and AGENTS.md natively); agents, commands, and MCP config are generated from the canonical Claude-side files by the bundled scripts. Plugin skills are exposed to OpenCode via skills.paths (see Mode E). The canonical copy always lives on the open side of the fence - if Claude Code access is capped, everything here still runs.
MANDATORY FIRST ACTION - Task Chain Bootstrap
On Claude Code, run these TaskCreate calls before anything else:
t0 = TaskCreate("Phase 0: Pre-Flight checks")
t1 = TaskCreate("Phase 1: Mode selection (Ingest / Sync / Validate / Drift / Setup)")
t2 = TaskCreate("Phase 2: Execute selected mode")
t3 = TaskCreate("Phase 3: Report, ledger, commit")
TaskUpdate(t1, addBlockedBy=[t0])
TaskUpdate(t2, addBlockedBy=[t1])
TaskUpdate(t3, addBlockedBy=[t2])
Mark t0 in_progress immediately, mark each phase completed at its boundary.
OpenCode or Cowork runtime:
TaskCreatedoes not exist there. Mirror the same four phases as atodowritechecklist (OpenCode) or a visible markdown checklist (Cowork) instead. Full translation recipe:references/tool-translation.md. Do not skip phase tracking just because Task* is unavailable.
When to Use
- Onboarding a marketplace, plugin, or repo so OpenCode can find and run its skills/agents/tools (Mode E)
- Adding OpenCode support to a repo or plugin that currently targets Claude Code only
- Converting Claude Code subagents into OpenCode agent files (frontmatter translation)
- Checking whether skills are portable across both runtimes before shipping
- Running a drift check after editing canonical sources, or wiring that check into CI
Skip when
- Creating a brand new skill or agent from scratch - use the skills-toolkit creation workflows, then run this skill's Validate mode on the result
- Syncing the local skill registry or marketplace versions - use aios-sync-skills and the 4/5-file version rule directly
- Validating a single Claude-only skill with no OpenCode target - use skill-validation-workflow
- Pushing pages or tickets to external systems - this skill only touches local runtime config and artifact files

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-sync is a skill published in the GitHub repository YoungLeadersDotTech/young-leaders-tech-marketplace (10 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 3,789 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.
