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.

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 | $0.00035 | $0.00312 |
| Opus 5 | $0.00017 | $0.00156 |
| Sonnet 5 | $0.00007 | $0.00062 |
| Haiku 4.5 | $0.00003 | $0.00031 |
Grade A, and why
add-path-type-assertions-or-realpath-resolve-calls-in-path-joini 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.
What it actually says
Add path-type assertions or realpath/resolve calls in path-joining utility functions
Trigger
- path.join
- realpath
- fs path
Required Procedure
- Add path-type assertions or realpath/resolve calls in path-joining utility functions
- Use absolute paths in test fixture creation
Forbidden Shortcuts
- (none recorded)
Delegation Template
When delegating a task affected by this skill, include:
SKILLS: file:.opencode/skills/generated/add-path-type-assertions-or-realpath-resolve-calls-in-path-joini/SKILL.md
Reviewer Checks
- Verify all path.join / path.resolve calls are preceded by absoluteness checks or resolution
Test Engineer Checks
- Add or update tests covering the trigger condition and the forbidden shortcut.
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.

add-path-type-assertions-or-realpath-resolve-calls-in-path-joini is a skill published in the GitHub repository ZaxbyHub/opencode-swarm (466 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 312 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 2026-08-30.
