Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00063 | $0.01212 |
| Opus 5 | $0.00032 | $0.00606 |
| Sonnet 5 | $0.00013 | $0.00242 |
| Haiku 4.5 | $0.00006 | $0.00121 |
Grade A, and why
lumin-repo-lens-write-gate 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 13d 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lumin Repo Lens Write Gate
This is the code-change transaction surface for lumin-repo-lens. It owns
pre-write and post-write together because post-write reads the
pre-write-advisory.<invocationId>.json produced by the same change.
Keep the human-facing answer short and kind. The assistant reads the cold artifacts; the human gets the next concrete step.
Core Contract
NO STRUCTURAL CLAIM WITHOUT MACHINE EVIDENCE
NO ABSENCE CLAIM WITHOUT STATED SCAN RANGE
Use hedging like "looks like" only when the internal label is degraded
or unknown.
Shared Engine
The shared engine lives in the sibling audit skill:
node ${CLAUDE_PLUGIN_ROOT}/skills/lumin-repo-lens/scripts/audit-repo.mjs
In a maintainer checkout, the equivalent command is:
node audit-repo.mjs
Slash commands still read <SKILL_ROOT>/references/command-routing.md from the
shared audit skill for exact flag routing.
Below, <SKILL_ROOT> means
${CLAUDE_PLUGIN_ROOT}/skills/lumin-repo-lens in plugin
installs, or the repo root in a maintainer checkout.
Below, <audit-repo> means whichever of the two commands above applies
to the current context.
This surface owns /lumin-repo-lens:pre-write and
/lumin-repo-lens:post-write.
References To Load
- Read
<SKILL_ROOT>/references/command-routing.mdfirst for slash-command routing. - Read
<SKILL_ROOT>/references/pre-write-intent-shape.mdbefore constructing or repairing intent JSON. - Read
<SKILL_ROOT>/canonical/pre-write-gate.mdfor the pre-write protocol, domain-cluster hints, exact shape lookup, and advisory language. - Read
<SKILL_ROOT>/canonical/any-contamination.mdfor planned type escapes, contaminated reuse demotion, and post-write escape deltas. - Read
<SKILL_ROOT>/references/lifecycle-modes.mdwhen exact flags, exit codes, or artifact names matter. - Read
<SKILL_ROOT>/references/glossary.mdand<SKILL_ROOT>/references/false-positive-index.mdwhen advisory output surfaces FP/tier terms that need explanation. The long FP case ledger is maintainer-only; do not load it for ordinary pre-write/post-write.
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.

lumin-repo-lens-write-gate is a skill published in the GitHub repository annyeong844/lumin-repo-lens (26 stars, last pushed 2mo ago), licensed MIT. It adds 63 tokens to every session and 1,212 once invoked, about $0.0003 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.
