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 | $0.00023 | $0.00375 |
| Opus 5.5 | $0.00009 | $0.00150 |
| Sonnet 5.5 | $0.00005 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
permission-manager 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.
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
What I do
- Review and summarize currently always-allowed commands
- Suggest safe read-only commands for auto-approval
- Add or remove commands from the allow list in opencode.json
- Configure skill-level permissions (allow/deny/ask) with wildcard patterns
- Audit permission configs for security and usability
When to use me
Use this when optimizing opencode's permission settings, reviewing allowed commands, or configuring skill access controls.
Workflow Steps
- Read current config: Load
~/.config/opencode/opencode.jsonor project-levelopencode.json - Summarize permissions: Identify currently allowed commands and skill permissions
- Suggest additions: Propose safe read-only commands for auto-allow (see recommended list below)
- Apply changes: Edit the config to add/remove permission entries
- Validate: Ensure JSON is valid after changes
Complements opencode's built-in allow/deny/ask permissions by auditing current config and recommending adjustments through conversation.
Key Rules
- Never allow commands that modify files, commit, push, or change system state
- Use wildcards appropriately (e.g.,
git status*not justgit status) - Confirm with user before modifying permission config
- Distinguish between bash command permissions and skill permissions
- Keep config organized: group related commands together
How to trigger me
Use the Task tool with the permission-manager subagent type:
/permissions
Or in natural language, ask opencode to "manage opencode permissions" or "review allowed commands".
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

permission-manager is a skill published in the GitHub repository mskadu/opencode-agent-skills (1 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 375 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 2026-08-31.
