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 | $0.16639 |
| Opus 5.5 | $0.00014 | $0.06656 |
| Sonnet 5.5 | $0.00007 | $0.03328 |
| Haiku 4.5 | $0.00003 | $0.01664 |
Grade A, and why
select-final-version 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 1mo 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 — 1,494 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Final Version Selector
Round 26: current decision schema 5 includes report_revision and
selection_request_id; schema-4 pointers are historical and rejected.
Candidate, policy, comparison, and lineage schema 3.
This skill performs final version governance. It chooses a final research candidate only from eligible audited candidates and only after the user confirms the selection policy. It is not investment advice.
Workspace Path Resolution
Read .open-xquant/workspace.yaml before reading or writing final-governance
artifacts. Resolve each key independently from paths: use
paths.versions_dir, paths.experiment_registry, paths.comparisons_dir,
paths.governance_dir, paths.final_dir, and paths.conversations_dir. Use
versions, experiments.jsonl, comparisons, governance, final, or
conversations, respectively, only when that key is absent; never derive one
key from another configured key. Each
configured value must be a safe workspace-relative path. Reject absolute paths,
traversal outside the workspace, and symlink escapes whose resolved target
leaves the workspace.
Call the resolved paths <version_root>, <experiment_registry>,
<comparisons_dir>, <governance_dir>, <final_dir>, and
<conversations_dir> below.
Phase Path Containment Preflight
Before any phase artifact read, write, directory creation, command, or handoff, run this preflight completely and block on any failure:
- Resolve
<version_root>canonically and require it to stay inside the workspace. Readcurrent.jsonfor active-state context. This contract explicitly owns cross-version inspection, so for each candidate setexpected_version_idfrom the referenced version idcandidate.version_id; do not substitutecurrent.json.active_version. - Set the intended version directory to
<version_root>/<expected_version_id>/and resolve it canonically. Require the intended version directory to remain inside the canonical version root and workspace. Readversion_manifest.jsononly from that exact directory and the manifestversion_idmust equalexpected_version_id. - Before using
phase_paths.09_backtestsorphase_paths.10_reports, require a non-empty workspace-relative string. Reject an absolute path and any..path segment. Resolve each path canonically, including symlinks, and require it to be the intended version directory or a descendant of it. A symlink escape outside the intended version directory is invalid. - On any identity or path failure, block before reads, writes, directory creation, commands, or handoffs. Do not normalize an unsafe path into acceptance and do not fall back to default phase paths.
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.

select-final-version is a skill published in the GitHub repository xingwudao/open-xquant (149 stars, last pushed 15d ago), licensed MIT. It adds 35 tokens to every session and 16,639 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 2026-08-30.
