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 | $0.00134 | $0.02758 |
| Opus 5 | $0.00067 | $0.01379 |
| Sonnet 5 | $0.00027 | $0.00552 |
| Haiku 4.5 | $0.00013 | $0.00276 |
Grade A, and why
oc-cost-ops 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 6d 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 — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cost Ops
On first invocation, read references/orchestrator.md and follow its welcome protocol.
Make LLM spend a first-class, attributable number in the pipeline. v1.5 added four AI-native skills; the predictable next question is "what did that cost me?" — and today the honest answer across opchain is "we don't precisely know." Cost Ops closes that loop: every skill phase that calls a model can attribute its spend, every checkpoint can carry a budget that gates when tripped, and every model choice can be checked against a tier-routing recommendation (don't run Opus on a phase Haiku handles).
This is not a tri-agent harness and not a billing system. It's the
instrumentation layer that sits underneath the model-facing skills — oc-claude-api
owns the request surface and the canonical pricing, oc-prompt-ops owns the eval
suite, oc-telemetry-ops owns local metering — and Cost Ops turns the token
counts they already produce into attributed dollars, budgets, and routing advice.
Pricing facts come from
oc-claude-api, not memory. Per-token prices, Batch-API economics (50% of standard), and cache read/write multipliers are sourced there. Current model IDs: Fable 5 (claude-fable-5), Opus 4.8 (claude-opus-4-8), Sonnet 4.6 (claude-sonnet-4-6), Haiku 4.5 (claude-haiku-4-5).references/pricing-reference.mdcarries a dated snapshot and always defers to oc-claude-api as source of truth.

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.

oc-cost-ops is a skill published in the GitHub repository asfbay-bit/opchain-skills (0 stars, last pushed 5d ago), licensed Apache-2.0. It adds 134 tokens to every session and 2,758 once invoked, about $0.0007 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.
