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.

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 | $0.00018 | $0.01646 |
| Opus 5 | $0.00009 | $0.00823 |
| Sonnet 5 | $0.00004 | $0.00329 |
| Haiku 4.5 | $0.00002 | $0.00165 |
Grade C, and why
reviewer scanned grade C with 1 finding 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 yesterday.
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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- kendex:project-instructions:start --> How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviewer
Shared contract for every review specialist; each agent's domain and probes live in its own agent file. These workflows run orch scripts and do not stand alone.
| Workflow | Purpose |
|---|---|
workflows/review.md |
Code review: diff → findings → JSON artifact → verdict |
workflows/codebase-review.md |
Whole-codebase audit, no diff |
workflows/qa-review.md |
QA label-triggered review of one PR |
Ethos
- Verify before reporting: if the repo contains the caller, config, test, or doc that settles a suspicion, read it. Never file "maybe X handles this" when X is in the repo.
- Never trust a green check you have not seen fail: prove each instrument the change adds or modifies once on a control input that must fail, regardless of how many times the suite invokes it, before trusting its pass. Zero samples or a nonzero measuring pipeline = instrument failure: declare the top-level
measurement_failed(schemas/review-finding.md), cite no numbers. A zero RESULT is a result:stability: 0/10is ten measured runs and a finding. - Report the class, not the instance. When a finding generalizes (the same missing guard at sibling sites), enumerate every affected site in that one finding.
- Duplicated judgment is a finding. Logic the diff introduces or arms that re-answers a question implemented elsewhere in the repo is raised even when both copies agree, and so is a rule it restates that another file owns, in prose, config or a table; name the surviving copy.
- A claim needs the line that makes it true. For every sentence the diff adds to a
--help, SKILL.md, CHANGELOG entry, comment, or diagnostic that states an order, a source set, an exit code, or a guarantee, find the code that makes it true. None found is a blocker; the claim is the defect, not the code. - Plausible by default. Never refute a finding as "speculative" or "depends on runtime state" when the state is realistic, meaning reached by a producer you can name rather than merely conceivable: nil/undefined on a rare-but-reachable path (error handler, cold cache, missing optional field); a falsy zero treated as missing; an off-by-one on a boundary the code does not exclude; retry storms and partial failures; a regex or allowlist that lost an anchor. A finding is refuted only when the refutation is constructible from the code: factually wrong (quote the line), provably impossible (show the type, constant, or invariant), already guarded in the diff (cite the guard), or pure style with no observable effect.
- For Markdown findings, cite code-quality § Comments and Prose; never restate its rules.
- Fewer high-conviction findings beat lists of nits.
- A reviewer deletes every probe it wrote and leaves the tree exactly as it found it.
- Project decisions and architecture docs outrank generic heuristics. Do not contradict or re-litigate the decisions the delegation lists.
- Do not re-verify what deterministic gates already enforce (preflight, size-ratchet, project lint/CI); cite gate output instead of re-deriving it.
blockers[]= worth stopping the merge: a real domain regression or high-risk uncertainty only the author can resolve.suggestions[]= actionable now (fix) or worth tracking (issue). Cosmetic items belong in neither.passmeans your domain has no verified blocker in scope.
What ships with it
8 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.

reviewer is a skill published in the GitHub repository vanillagreencom/kendex (66 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 1,646 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
