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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 17 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00036 | $0.00415 |
| Opus 5.5 | $0.00014 | $0.00166 |
| Sonnet 5.5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade A, and why
opencode-controller 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 1mo 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
Opencode Controller
Core rule
Clawdbot does not write code. All planning and coding happens inside Opencode.
Pre-flight
- Ask the user which AI provider to use.
- Ask how the provider should be authenticated.
- Do not proceed without confirmation.
Session management
- Start Opencode.
- Open session selector using: /sessions
- If the current project already exists:
- Select the existing session.
- Never create a new session without user approval.
Agent (mode) control
- Open agent selector using: /agents
- Available agents:
- Plan
- Build
- Always select Plan first.
- Switch agents whenever required using
/agents.
Model selection
- Open model selector using: /models
- Select the user-requested provider.
- If authentication is required:
- Copy the login link provided by Opencode.
- Send it to the user.
- Wait for confirmation before continuing.
Plan agent behavior
- Ask Opencode to analyze the task.
- Request a clear step-by-step plan.
- Allow Opencode to ask clarification questions.
- Review the plan carefully.
- If the plan is incorrect or incomplete:
- Ask Opencode to revise it.
- Do not allow code generation in Plan.
Build agent behavior
- Switch to Build using
/agents. - Ask Opencode to implement the approved plan.
- If Opencode asks any question:
- Immediately switch back to Plan.
- Answer and confirm the plan.
- Switch back to Build.
Completion
- Repeat the Plan → Build loop until all user requirements are satisfied.
- Never skip Plan.
- Never answer questions in Build.
Output format
- Show all slash commands explicitly.
- State which option is selected.
- Provide login links verbatim.

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.
- 1mo ago First seen · 78 lines · 36 tokens per session scan A 6535df08ba8b
opencode-controller is a skill published in the GitHub repository zai-org/Synapse (462 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 36 tokens to every session and 415 once invoked, about $0.0001 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 2026-08-30.
