this repository (NyedisInc/CarnivoreAI-Catalog) is the public place skills, themes and plugins are published from. a build job reads it, proves every release against this repository's own git history, signs an index, and deploys that index to https://catalog.carnivore.ai/v1/index.json with a detached signature beside it at .../index.json.minisig.
the app that reads it pins two public keys and refuses anything that does not verify under them. so the honest summary of what this repository is: a place where bytes get signed, and a job that refuses to sign anything it cannot prove.
| path | what it holds |
|---|---|
skills/<handle>/<name>/ | the skill itself, exactly as it gets installed |
themes/<handle>/<name>/ | a theme: theme.json plus raster images, no code. the one exception is the first-party handle nyedis, whose themes may also carry an effects script, the base it imports and a mascot svg (tools/index_builder/themes.py) |
plugins/<handle>/<name>/ | a plugin: inert markdown and one .claude-plugin/plugin.json, no hooks, servers or scripts |
releases/<handle>/<name>/<version>.json | one signed release statement |
revocations/<handle>/*.json | signed statements withdrawing a key or a version |
publishers/<handle>.json | which keys a publisher signs with |
publishers/_index.json | the public half of the index signing key |
catalog.yml | the few settings that change what gets published |
digest_vectors.json | shared with the app, so two digest implementations cannot drift |
tools/index_builder/ | the build job |
site/ | the header file and the one page the host serves |
.claude-plugin/marketplace.json | generated; what claude plugin marketplace add reads |
the statement names the folder's digest. if it lived inside the folder it would be part of what is being digested, and no digest could ever be right: the file would change the number it is trying to state. so the skill folder holds only what gets installed, and the statement sits beside it under releases/.
each statement names a commit in this repository. the build job checks that commit out, recomputes the digest with the same code the app uses, and compares. so the index never points at bytes nobody signed, and the app can download codeload.github.com/NyedisInc/CarnivoreAI-Catalog/tar.gz/<commit> and arrive at the same number on its own.
skills/<your handle>/<name>/. it needs a SKILL.md with a yaml front matter block carrying at least a description.scripts/catalog-bootstrap/sign_release.py. it computes the digest, renders the statement, signs it with your minisign key and writes releases/<handle>/<name>/<version>.json. cd tools && python3 -m index_builder --repo-root .. marketplace --write.claude-plugin/marketplace.json, then open a pull request.the pull request check refuses a diff that edits a skill folder without a matching release, because the catalog would otherwise go on serving the version you just edited away from.
it also refuses a branch whose .claude-plugin/marketplace.json no longer matches the releases, and prints the command above. the build job cannot write that file itself: it holds a read only token, and a job that could push to main would be a way around the review every other published byte goes through. so the publisher regenerates it, and the check is what makes sure they did.
claude plugin marketplace add NyedisInc/CarnivoreAI-Catalog
claude plugin install sme@carnivoreadd reads one file, .claude-plugin/marketplace.json, and each entry in it points straight at a skill folder under skills/. a folder holding a SKILL.md and no skills/ subdirectory loads as a single skill, so no plugin manifest is written into a skill folder and no copy of one is kept anywhere else. that matters: a release statement names a folder's digest, so a file added inside it would invalidate a signature, and a copy of it in a second tree would be free to drift from the bytes that were signed.
this path is a convenience and it is NOT the signed one. the cli copies the skill folder as it stands on main at the moment you run it, not the commit a publisher signed. it does not check a release statement, and nothing here can make it.
the signature chain proves the catalog index, not the copy the cli made. minisign covers v1/index.json and the detached .minisig beside it; no signature artifact is written into the plugin cache and nothing there is verified afterwards. a user who wants the exact bytes a publisher signed installs through the app instead, which checks the index against a pinned key and then checks the folder digest before staging anything. the signature checking installer is the app's own catalog screen, which verifies the index against a pinned key before it stages anything. the same file is served at https://catalog.carnivore.ai/.claude-plugin/marketplace.json for anyone who wants to read what they are about to add.
| job | what it holds | what it does |
|---|---|---|
inputs | nothing | says which inputs are present, so a skipped pipeline is not silent |
verify | nothing | proves every release, refuses an unreleased skill change, assembles an unsigned index |
review | a model api key | writes one security review per new version |
sign | the index signing key | signs the index and verifies its own signature |
deploy | nothing secret | zips and ships to amplify, then checks the published headers |
verify runs on every pull request. the other three never do. secrets live in aws secrets manager and are read through a role assumed with openid connect, so no long lived aws credential is stored in github. every action is pinned to a commit sha. the index is re-signed weekly even when nothing changed, which bounds an undetected key compromise to a week rather than to forever.
every version gets one model's read of its own text. it answers two questions in the same pass, because that is the ruling: does the frontmatter description disclose what the body actually instructs, and does the body do anything on the security checklist. it returns a verdict of clean, flagged or blocked.
five kinds of finding block a publish: prompt_injection, credential_access, obfuscation, opaque_payload and settings_write. each is something no legitimate skill in a public catalog needs to do, so a publish stops rather than a reader being asked to notice a warning. the other seven, instructions_write, network, shell_exec, file_delete, privilege, description_mismatch and other, are advisory: a skill that fetches documentation or runs a command is doing its job, and the detail names the host or the path so a human can judge.
settings_write (blocking) is an edit to a file that grants capability: settings.json, settings.local.json, managed-settings.json, .mcp.json, ~/.claude.json, ~/.codex/config.toml, a permission allow or deny list, a hook or a script a hook runs, a shell rc file, or any file under .claude/agents/ or .claude/commands/, or another skill's SKILL.md, whatever its frontmatter says (an agent file with no tools line inherits every tool).
instructions_write (advisory, a warning only) is a skill that creates, appends to, rewrites or deletes lines in a plain-prose agent instruction file: CLAUDE.md, CLAUDE.local.md, AGENTS.md, AGENTS.override.md, MEMORY.md, any .md file under .claude/rules/, GEMINI.md, .github/copilot-instructions.md, files under .cursor/rules/ or the legacy .cursorrules, and .windsurfrules, in any directory. it covers only the act of editing, and the finding's detail names the file or files. what the skill writes into the file is judged as if it said it to the agent directly: text that overrides the user's rules is prompt_injection, text that tells a later agent to edit settings is settings_write, a secret read or an @path import of one is credential_access, and text or an import that is downloaded, generated or not shown to the reviewer is opaque_payload. each is reported as its own finding beside the instructions_write one.
app compatibility. Carnivore app builds before the forward-compatible-kinds release do not know instructions_write, and they drop an item whose review carries a kind they do not know. the catalog holds items with this kind until that release is out.
a blocked answer sticks. findings that derive blocked keep the answer and record blocked even when the model stated a softer verdict, and a committed blocked review of the same bytes is not overwritten unless review is run with --replace-blocked. the way to publish a blocked item is --override-blocked. the check is on the digest, so the same bytes under a new version or a new name are refused too. the residue: a blocking finding next to some OTHER malformed field (a bad line number, a misspelled kind, an empty summary) is still discarded as unavailable and needs a human re-run. that is not absolute.
the reviewer model is anthropic/claude-sonnet-5.5, set by review_model in catalog.yml.
the verdict is re-derived, never taken on trust. the model is asked for it so its answer is self consistent, and then the verdict is recomputed from the findings and compared. a model that lists a blocking finding and calls itself clean is recorded blocked; only a stated verdict stricter than its findings is discarded, which records unavailable. the same re-derivation runs on a committed review when it is read, so hand editing the verdict in the file refuses the file rather than publishing it.
the skill text is data, not instructions to the reviewer. it is framed by === BEGIN SKILL TEXT === and the prompt says so, because a skill IS instructions to an agent: text addressed to the reviewer is the native attack on this artifact class, and it is reported as prompt_injection rather than followed.
every utf-8 text member is shown, not three categories of file. SKILL.md first and executables next, so the size cap falls on the least important files last. a file that is not text, and a file the cap left out, is named with its size and marked as not shown, so a payload nobody can read is a thing the reviewer can raise rather than a thing it never heard of.
it is written after the publisher's signature has already been verified, so it is covered by the index key alone. an index key holder could therefore forge a benign review. that is why the verdict gates the PUBLISH PIPELINE and is never treated by the app as proof of anything: the SKILL.md text is always shown next to it and the consent button stays a human act.
when the review cannot be obtained, for any reason at all, the index records status: "unavailable" and no summary and NO VERDICT. the app renders that literally as "no ai review". a blank review must never read as a clean one, and an unavailable one is never a clean one.
a review is committed at reviews/<handle>/<name>/<version>.json, mirroring the release tree one level out, so the signed statement for a version and the review of the same bytes sit at the same coordinates. the file holds exactly the review block the index carries, plus the digest it was taken over.
a review is bound to a digest, not to a version number. the build refuses to reuse a committed review whose recorded digest is not the digest of the version it is building, because a review of different bytes is not a review of these bytes. a malformed artifact is treated as absent rather than as a review, and the job log names the file and the reason.
the build fills in each version's review from the first of these that answers:
reviews/ for that version, at a matching digest.nothing becomes unreviewed. the third rung is unchanged: a version with neither a committed nor a published review is reviewed at build time exactly as it always was. the first two rungs stop the catalog paying twice for the same bytes; they do not stop anything being reviewed. the review step writes a table into the job summary saying which rung answered for every version, so a reader can see whether a model ran at all.
approval is what will write these files. the ruling of 2026-09-16 is that a submitted skill sits in a bucket until it is approved, and the approval runs the scan once against the bytes it is about to publish and commits the result beside the release. that endpoint is not built yet. the same operation runs by hand:
cd tools && python3 -m index_builder --repo-root .. \
review --handle <handle> --name <name> --version <version>it verifies the release statement first and binds the review to the digest that verification produced, so a review can never be committed for bytes nobody signed. it reads the model key from OPENROUTER_SECRET_VALUE, and it writes nothing at all when the scan fails: an unavailable review is a transient failure, not a verdict, and committing one would leave a file a reader could mistake for a finding.
the approval moment is before any commit, so the same command takes --staged <folder> and reviews a skill folder on disk, computing the digest from those bytes with the code the app uses. that is what scripts/catalog-bootstrap/fetch_approved.py in the app's repository runs after it stages an approved submission, and it prints the publish command only when this exits zero.
then commit the folder exactly as it was reviewed. the artifact the staged review writes is bound to the digest of the bytes it read, so any edit to the folder after that point leaves a version whose committed review describes something else, and check-reviews refuses the build naming both digests. the fix is to run the review again over the bytes you actually mean to publish and commit the artifact it writes, in the same change as the folder.
a blocked verdict exits non zero. to publish one anyway, run it again with --override-blocked "<reason>". the reason, who you are and the moment are written into the committed review as an override block. it NEVER changes the verdict: the artifact still says blocked, the card still marks the item, and the file sits under reviews/, which CODEOWNERS routes to the owner, so the override shows up in the pull request diff rather than being applied silently. --require-clean refuses anything that is not clean, not only what is blocked.
a version publishes only with a committed review bound to its exact bytes. check-reviews runs in verify, which every pull request reaches, and it refuses the whole build unless every published version carries a review under reviews/ whose recorded digest IS that version's folder digest. edit the folder, re-run the review. three things refuse, named apart in the message along with both digests, because the move that fixes each one is different: no committed review for these bytes (there is none, or the file exists and cannot be read), committed review is for a different digest (the folder changed after the review was taken), and blocked without override (the review read these exact bytes and refused them). a gate that only lives in the script a maintainer runs is a gate a hand commit walks past.
only a committed review approves bytes. a review this catalog already published for the same digest is good enough to SAVE A MODEL CALL, which is all rung 2 above uses it for, and it is not good enough to ADMIT anything. the live index is the artifact the build is replacing, so letting it approve bytes makes the gate read its own output as its input, and one bad build would approve those bytes for every build after it. a committed artifact sits under reviews/, which CODEOWNERS routes to the owner, so it reaches publication through a diff a human read.
what this closes. until 2026-09-19 an absent committed review and a review of other bytes both printed a row and passed. so an operator who edited a skill folder after the approval pull reviewed the staged bytes, or who never took a review at all, published bytes nothing had approved: the build reviewed them and wrote the verdict into the index, which RECORDS a finding rather than acting on it.
migrating a version published before this rule, where the review exists only in the signed index:
cd tools && python3 -m index_builder --repo-root .. \
review --handle <handle> --name <name> --version <version> \
--from-index <a verified index.json>it verifies the release statement first and copies the published review only when the index bound it to THAT digest, so a review of other bytes cannot be laundered into reviews/ by editing what it is copied from. it calls no model, needs no api key, and carries the verdict, the findings and any override through unchanged. it approves nothing by itself: a copied blocked verdict is still blocked and still refuses the build.
a review with no verdict is stale. everything reviewed before the verdict existed answered a question the gate does not ask, so neither the committed tree nor the live index carries one forward: those versions are reviewed once more under the current prompt.
every version also carries a quality grade of its own text and structure, written at publish time beside the review and shown in the verify job's summary. it asks a different question from the review: not whether a skill does anything damaging, but whether it is built the way the agent skills specification says to build one, so an agent can find it, load it and follow it.
a low grade never blocks a publish. what a publisher ships is the publisher's business. nothing in the build refuses a version for its grade, and nothing ever should.
every rule the grader applies cites the published requirement or recommendation it came from, by url, in the table at the top of tools/index_builder/grade.py. a rule that cannot be traced to one does not exist, and a test fails the build if one appears. where the specification asks for a judgement a machine cannot make, the grader either uses a stated proxy and says in the note that it is one, or it declines and records the rule as not graded. a rule that did not run is never reported as one that passed, for the same reason a blank review must never read as a clean one.
a folder with no readable SKILL.md grades as ungraded rather than as an f. an f is a measurement; that is the absence of one.
signing proves who wrote a skill. it does not prove a skill is safe. a verified skill is a provenance claim: it makes an attacker attributable, it does not make the bytes harmless. that is the whole reason the install preview shows the text and the review, and why an update whose SKILL.md changed needs fresh consent.
mainmain requires a pull request, and requires the verify and assemble check to pass before a merge. force pushes and branch deletion are refused. code owner review is required, so CODEOWNERS is a control rather than a suggestion for anybody who is not the owner.
administrators are deliberately NOT included. including them is the textbook answer and it is the wrong one here: this is a one person repository, so an owner who cannot approve his own pull request and cannot bypass the check has no way to land an urgent fix to his own catalog, and the failure mode of that is a catalog that cannot be repaired. the owner keeps a way through. every other contributor is held to the full set.
what that trades away, said plainly: the protection stops a mistake and stops a contributor, and it does not stop a compromise of the owner's own account. nothing set at this layer could.
.claude-plugin/marketplace.json is generated, and every description in it is copied verbatim from a publisher's own SKILL.md, inside a folder whose digest that publisher signed. so this repository's no dash rule does not reach it. that rule governs prose we write. normalising a character in generated output would be rewriting somebody else's signed words, and the same reasoning would then demand stripping the emoji, arrows and box drawing that four of the six published skills carry in their own descriptions.
control characters are the one exception, and they are a different case: a C0 control is not a word, it is an instruction to whatever renders the file. frontmatter.brief_of strips every one of them, and a test asserts the shipped file carries none.
