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 | $0.00083 | $0.00598 |
| Opus 5 | $0.00042 | $0.00299 |
| Sonnet 5 | $0.00017 | $0.00120 |
| Haiku 4.5 | $0.00008 | $0.00060 |
Grade A, and why
orcho-core-verification-matrix 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.

Orcho Core Verification Matrix
Map changed orcho-core surfaces to focused test commands before the full
integrity gate.
Owns
- targeted test and smoke selection for
orcho-core - pytest mark/path recommendations
- downstream smoke recommendations before final gate
Does Not Own
- implementation
- domain semantics
- final readiness gate ->
orcho-integrity-pipeline

Invariants
- Targeted tests do not replace final
ruff, pytest gate, andgit diff --check. - Public schema changes include snapshots and downstream smoke.
- Prompt golden diffs must be reviewed, not blindly accepted.
Verification
- This skill recommends commands; it does not replace running them.
- If public schema or MCP-visible shape changes, include snapshot and MCP smoke commands.
Output
Name primary domain skill, targeted commands, whether full pytest is still required, downstream smoke, and blockers if any command cannot run.
Command Policy
- Run commands from
orcho-coreunless the command explicitly names another repo. - Prefer
python -m pytest -q <path>for targeted tests. - Final readiness still belongs to
orcho-integrity-pipeline.
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.

orcho-core-verification-matrix is a skill published in the GitHub repository symphos-ai/orcho-core (5 stars, last pushed 2d ago), licensed Apache-2.0. It adds 83 tokens to every session and 598 once invoked, about $0.0004 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.

create-plugin
Use when authoring a new octomux plugin package — package layout, the apply(ctx) export, choosing a registrar, shipping kind presets, testing locally, and confirming with octomux doctor.
review-deep
Drive the deep-review phase of an automated PR review. Consumes the walkthrough, runs the deterministic deep-review workflow (parallel lenses → adversarial validation → code-enforced threshold/caps), drafts the surviving findings, and completes the review run.
review-orchestrator
Drive an automated PR review. Produces a structured walkthrough plus inline draft comments via the octomux review CLI. NEVER posts to GitHub directly — publishing is human-gated.
review-pr
Use when reviewing a pull request, posting PR review comments, or when user says /review-pr. Reviews code with parallel agents and posts a pending GitHub review with inline comments.
review-walkthrough
Drive the walkthrough phase of an automated PR review. Produces a structured walkthrough JSON only — no inline comment drafts. The deep-review agent is attached automatically by the server after this agent finishes.
create-pr
Use when creating a pull request, opening a PR, or pushing and creating a PR for an octomux task.
