Octos is a self-hosted AI assistant that runs on a user's computer and can connect to different AI providers, execute code, browse the web, remember information, schedule jobs, and create documents through browser, terminal, and messaging interfaces. The catalogue entries extend or configure this assistant's workflows.
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 | $0.00029 | $0.00337 |
| Opus 5.5 | $0.00012 | $0.00135 |
| Sonnet 5.5 | $0.00006 | $0.00067 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
harness-starter-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Harness Starter: Report
A report generator that produces a markdown artifact as its single deliverable. Copy this crate when you want to build an app that ships a rendered document (weekly summary, research brief, status report, etc.).
What this starter demonstrates
primary = "reports/*.md"— glob-based artifact resolution.file_size_min:$primary:256— validator gates delivery on non-trivial content length.on_failure: ["notify_user:..."]— structured failure notification.
See docs/OCTOS_HARNESS_DEVELOPER_GUIDE.md for the full contract.
Tools
generate_report
Generate a markdown report for a topic.
{"topic": "Q1 Sales Review"}
Parameters:
topic(required): report topic; also used to derive the filename (reports/q1-sales-review.md).body(optional): markdown body. When absent, a stub body is written.
Artifact:
- writes
reports/<slug>.md - the workspace policy's
primaryglob (reports/*.md) resolves to this path. - the runtime refuses to mark the task
readyuntil the file exists and is at least 256 bytes (the starter writes padded stub bodies to keep the smoke test deterministic).
What ships with it
6 files 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.
