From 63330d98309e87bb1b0bf7b0f179a601f94ea737 Mon Sep 17 00:00:00 2001 From: "claude[bot]" <41898282+claude[bot]@users.noreply.github.com> Date: Sat, 25 Jul 2026 23:14:00 +0000 Subject: [PATCH 01/40] feat: lint OpenAI Codex plugins and marketplaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Codex plugin (`.codex-plugin/plugin.json`) and marketplace (`.agents/plugins/marketplace.json`) manifests were invisible to skillsaw — not detected, not in the lint tree, not linted. This adds four rules, two repo types, and two lint-tree nodes for them. Codex gets its own rules rather than overloading the Claude ones. The schemas are not compatible: Claude requires `owner` (0 of the Codex catalogs surveyed have it), Codex's source types include `local` (209/209 entries in openai/plugins) which the Claude rule would call unknown, and Codex publishes no semver constraint on `version`. `.claude-plugin/ marketplace.json` stays owned by `marketplace-json-valid`. New rules, all `enabled: auto` gated on the new repo types: - codex-plugin-json-valid — manifest fields and every path it declares - codex-plugin-structure — "Only plugin.json belongs in .codex-plugin/" - codex-marketplace-json-valid — catalog schema, source types, policy - codex-marketplace-registration — catalog and directories agree, with a SUGGEST autofix Two pre-existing false positives on Codex repos are fixed: a bare `plugins/` directory made `marketplace-json-valid` demand a Claude manifest (fired on 13 of 35 real Codex marketplaces, openai/plugins among them), and `plugin-json-required` demanded a Claude manifest from Codex plugins that ship a `commands/` directory. A plugin the Claude marketplace itself lists is still required to have one. Codex plugin `hooks/hooks.json` is routed to the existing HooksBlock, so Codex plugins get hooks-json-valid and hooks-dangerous rather than duplicate rules. Validated against 35 real Codex repositories (~460 manifests): zero findings on openai/plugins, and every finding elsewhere traced to a real divergence — `..` escaping the plugin root, a stray `hooks.json` inside `.codex-plugin/`, an unreplaced `[TODO: ./assets/icon.png]`, duplicate catalog names, a dangling local source. ai-helpers is byte-identical on all 481 violations.

charset=UTF-8 Content-Transfer-Encoding: 8bit Three BLOCKING findings from the panel, plus the suggestions and notes: - marketplace-json-valid stood down from "Marketplace file not found" for any repo with a Codex catalog, even one shipping real Claude plugins. It now stands down only when no discovered plugin carries .claude-plugin/plugin.json, matching plugin-json-required's rule. - codex-marketplace-registration demanded that plugins under .codex/plugins/ — where Codex installs plugins into a developer's checkout — be listed in the repository's own catalog. That failed the lint of anyone who installed a Codex plugin, and `fix --suggest` wrote the third-party install into the published catalog. They stay discovered (their hooks and skills are still linted) but are skipped by the registration check. - urlparse() raises "Invalid IPv6 URL" on an unbalanced '['; the exception escaped check() and aborted the whole rule, so the credential and scheme checks failed open on exactly the input they exist to catch. It now reports a violation. Also: empty bare-string marketplace sources are an error rather than an INFO about './'; a non-string policy value-list from config no longer crashes the rule's own error message; a duplicate entry name falls through to the kebab-case check; dead codex_marketplace_data removed; codex_plugin_name and the marketplace-path cache go through the shared readers instead of hand-rolled I/O and __dict__.

A manifest may point ``hooks`` at a file other than the conventional ``hooks/hooks.json``; that file carries the same executable commands, so it now becomes a HooksBlock and gets hooks-json-valid, hooks-dangerous and hooks-prohibited. Inline hooks objects and paths that escape the plugin root are not followed. - Discover skills inside installed Codex plugins. ``.codex/plugins/`` is hidden, so the repository-wide skill scan never walks it; Codex plugin roots now join Claude plugin roots as embedded-skill roots. - Reject an empty ``source`` discriminator in a Codex marketplace entry as missing rather than as an unknown future source type, so an entry Codex cannot resolve no longer passes a default ``fail-on: error`` run. - Add Codex plugins and marketplaces to the README's supported-format summary, and document the hooks discovery contract in docs/repo-types.md.

Discovery - .codex-plugin/ is the plugin evidence, not the manifest inside it, so a directory whose plugin.json was deleted keeps its CODEX_PLUGIN type and codex-plugin-json-valid reports the missing entrypoint. - A sibling catalog named *marketplace.json is taken on existence, so broken JSON in api_marketplace.json is reported rather than hidden. Unrelated JSON in .agents/plugins/ still has to duck-type. - Skills are followed to the directories the manifest's `skills` field names, not just literal skills/ — for a plugin under .codex/plugins/ that is the only route into the tree. - CODEX_PLUGIN and CODEX_MARKETPLACE joined _TYPE_PRIORITY, below the Claude types, so a Codex-only repo stops reporting `unknown`. Lint tree - Inline `hooks` objects become a CodexInlineHooksBlock and reach hooks-dangerous, hooks-prohibited and hooks-json-valid. A `curl | sh` SessionStart hook written inline was invisible to all three. - A Codex-only plugin's .mcp.json is attached, so the MCP rules see it when no PluginNode owns the directory. - The agentskill-* rules share one SKILL_REPO_TYPES set, now including CODEX_PLUGIN, so Codex-hosted skills are actually checked. Rules - Manifest and marketplace paths are rejected when they resolve outside their root through a symlink, not only on `..` and absolute strings. - `name: ""` is a required-field error in both manifests instead of falling through to the kebab-case warning a default fail-on:error lets pass. - An npm registry must name a host: "https:registry.example.com" parsed clean before. - A present `category` must be a non-empty string. - Local marketplace entries register by path only. Crediting name and path independently let one crossed entry cover two plugins. - plugin-json-required keeps firing on a directory with an explicit .claude-plugin/ marker — a dual-ecosystem plugin whose Claude manifest is gone is exactly what that rule reports. Validation: 3103 tests pass; openai/plugins is byte-identical at 6755 findings and zero from codex-* rules; openshift-eng/ai-helpers exits 0.

Benjamin Date: Sun, 26 Jul 2026 13:53:31 -0400 Subject: [PATCH 06/40] Route Codex mcpServers, malformed inline hooks, and Codex-only docs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second round of Codex reviewer findings. - `mcpServers` is followed in both non-conventional forms — a path to a file other than `.mcp.json`, and the inline server map real plugins ship. Those servers name commands the host spawns, so they now reach mcp-valid-json and mcp-prohibited the way `.mcp.json` already did. A `CodexInlineMcpBlock` carries the by-value form, sharing the `_InlineJsonPayload` behaviour with the inline hooks block. - A malformed inline hooks event is carried into the tree instead of filtered out. `codex-plugin-json-valid` deliberately skips hook objects, so `{"SessionStart": {...}}` with a non-list value was reported by nothing at all; hooks-json-valid now rejects it. Merging copies the list rather than aliasing it, since the manifest dict comes from the shared read cache. - `skillsaw docs` documents Codex-only plugins. `extract_docs()` walked `PluginNode`s alone, so a repository it had just classified `codex-plugin` produced no plugin metadata, hooks or MCP documentation. Dual-ecosystem plugins are still documented once, through their Claude manifest. The three near-identical manifest-path readers (`hooks`, `skills`, `mcpServers`) now share `_codex_declared_paths`, and the inline object readers share `_codex_inline_objects`. Validation: 3114 tests pass (11 new; 7 fail without these fixes, the rest are the deliberate still-works guards). openai/plugins lint output stays byte-identical at 6755 findings; `skillsaw docs` on it exits 0 and now emits plugin metadata. openshift-eng/ai-helpers exits 0.

[PATCH 07/40] Stand down on installed plugins; fix discovery and docs gaps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Panel BLOCKING plus nine Codex connector findings. Installed plugins (panel BLOCKING) - codex-plugin-json-valid and codex-plugin-structure now stand down on `.codex/plugins/*`. `is_codex_installed_plugin` had one call site, so a developer who installed a third-party plugin failed a default `fail-on: error` run on someone else's manifest — skillsaw does not walk `.claude/plugins/*` at all, which settles the intended posture. The hooks, MCP and agentskill rules keep running there: those commands execute in this checkout, and that coverage is the point. A defective vendor plugin is now in `codex/broken`, with a companion test asserting hooks-dangerous still fires on it so no future fix can over-correct into a blanket exclude. docs/repo-types.md states the full contract per rule. Discovery - `Path.resolve()` is wrapped everywhere it touches a manifest string. An embedded NUL raises ValueError, and discovery runs during `RepositoryContext.__init__`, so it aborted the whole lint instead of producing a violation. - `plugins/*` and `.codex/plugins/*` are checked for containment. Those probes use `is_dir()`, which follows a symlink out of the repository and pulled an external manifest, hooks, MCP servers and skills into the tree. - Inline `hooks` and `mcpServers` produce one block per declared object rather than a merge. Merging had to discard an occurrence when an array repeated an event or a server name, and either loss hides a defect. Activation - Codex plugin rules and the agentskill-* rules now fire for CODEX_MARKETPLACE too, the same way PLUGIN_REPO_TYPES carries MARKETPLACE. `--type codex-marketplace` discovered every local plugin and then checked none of them. Rules and docs - File-valued manifest fields reject a directory (and `skills` a file). `exists()` passed, then the tree dropped the declaration silently. - `skillsaw docs` renders a Codex catalog as a marketplace. `marketplace_data` only loads the Claude manifest, so a Codex catalog fell to the single-page renderer, which shows plugins[0] and drops the rest — on openai/plugins that was 1 rendered plugin out of 180. - MCP servers report their real source file instead of a hard-coded `.mcp.json`. Also moved the pure Codex helpers to `formats/codex.py` alongside `formats/promptfoo.py`, and documented why `_InlineJsonPayload.inline_data` must be redeclared in each subclass — both panel follow-ups. Validation: 3132 tests pass (18 new; 12 fail without these fixes). openai/plugins lint output byte-identical at 6755 findings; `skillsaw docs --format markdown` on it goes from 1 file to 181. openshift-eng/ai-helpers exits 0.

From 3564027229f0389490d6fbc5688949114009893d Mon Sep 17 00:00:00 2001 From: Stephen Benjamin Date: Sun, 26 Jul 2026 14:43:49 -0400 Subject: [PATCH 09/40] Harden path resolution, discovery containment and docs authorship MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Round four: one CodeRabbit finding and six from the Codex connector. - `safe_resolve` and `escapes_root` also catch `RuntimeError`. A symlink loop raises `RuntimeError` before Python 3.13 and `OSError` from 3.13 on; skillsaw supports 3.9-3.14, so catching only the latter left the lint aborting on the older half of the range. Caught by CodeRabbit. - `.agents/plugins/marketplace.json` is taken on existence rather than `is_file()`. A directory in place of the reserved entrypoint declassified the repository instead of being reported. - `_discover_skills_in_dir` takes an optional containment root, passed for Codex plugins. `skills/external` as a symlink out of the repository was still followed — the direct probes were fixed last round, the recursive child scan was not. The pre-Codex call sites pass nothing, so their behaviour is unchanged. - `"skills": "./"` names the plugin root, which is a legal place to keep a skill. File-valued fields still reject it. - Duplicate entry names are tracked across sibling catalogs. Codex aggregates them into one namespace and `skillsaw docs` writes one page per name, so two catalogs claiming a name silently lost a page. The single-catalog message is unchanged; the other file is named only when it differs. - `skillsaw docs` no longer publishes `.codex/plugins/*` installs as members of the repository's catalog — the same authorship line the registration and manifest-quality rules draw. - `_plugin_filename` sanitises every platform separator, the drive-letter colon and `..`. A kebab-case violation is only a warning, so `docs` cannot assume `lint` rejected a hostile name first; on Windows `\` is a real separator and the joined path could leave the output directory. The resolve-failure tests inject the exception rather than building real symlink loops — no single interpreter in the supported range takes both branches, so a real loop would only ever exercise one of them. Validation: 3153 tests pass (20 new; 10 fail without these fixes). Merged main (#458) and regenerated.

Stephen Benjamin Date: Sun, 26 Jul 2026 14:47:27 -0400 Subject: [PATCH 10/40] Only report cross-catalog duplicates when the sources differ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Caught by running the previous commit against openai/plugins: the cross-catalog duplicate check put 29 spurious ERRORs on the official reference catalog. It lists 29 of its 180 plugins in both marketplace.json and api_marketplace.json with byte-identical sources — a curated second listing, not an ambiguity. Codex resolves both to the same plugin and `docs` writes the same page either way. The defect the reviewer described is narrower: two catalogs claiming one name for *different* sources, where aggregation has to pick one and a docs page is genuinely lost. Only that is reported now. Within a single file any repeat stays a defect, exactly as before. openai/plugins is byte-identical to the pre-branch baseline again.

These are its optional follow-ups, minus the two it explicitly scoped elsewhere. - **Symlink escape (Security + QA, converged).** The guard checked the plugin directory but not the reserved subdirectory, so `plugins/victim/.codex-plugin -> /outside` passed: `victim` is genuinely in-repo, and `is_dir()` follows the link. skillsaw read an out-of-tree manifest, and codex-plugin-structure enumerated that external directory's filenames into lint output under an in-repo-looking path. Both halves are containment-checked now, with the companion test QA specified. The identical hole on the Claude side is left alone — the panel asked for that as a separate PR, and it is not this PR's to widen. - **extract_docs was O(plugins x skills).** Every plugin re-resolved every SkillNode in the tree — 99.2% of runtime on a 180-plugin catalog. Both sides are resolved once now: openai/plugins goes 2.67s -> 1.42s. - **Removed the only rule-package-to-rule-package import in the tree.** `is_absolute_path` / `has_parent_traversal` move to a new `skillsaw.paths`; `marketplace/json_valid.py` re-exports them so any external importer keeps resolving. - Minor: `safe_resolve` in `is_codex_installed_plugin`; `_extract_hooks` / `_extract_mcp_servers` typed `LintTarget`, which is what they always accepted; the duplicate `exists()` stat hoisted; docs/extractor imports `safe_resolve` from `formats.codex` rather than the context re-export. Not taken, both by the panel's own reasoning: the Claude-side symlink hole (separate PR), and the `registration.py:165` apostrophe truncation, which is a pre-existing Claude bug unrelated to Codex. Validation: 3155 tests pass. openai/plugins byte-identical to the pre-branch baseline; `docs --format markdown` still 181 files; openshift-eng/ai-helpers exit 0 with an unchanged 480 findings.

The reasoning stays where it explains the code; the archaeology goes. - `docs/repo-types.md` said the same thing three times for `hooks`, `skills` and `mcpServers`.

All reproduce; each fix carries a test verified to fail without it. Containment — three paths reached outside the checkout - The catalog entrypoint is resolved and rejected when it leaves the repository. This one had teeth: codex-marketplace-registration writes the catalog back when it registers a plugin, so `fix --suggest` through a symlinked marketplace.json would have overwritten an external file. - An existing `.codex-plugin/plugin.json` must itself resolve inside the plugin. A *missing* manifest still counts as a plugin, so the earlier "discovery keys off the directory" behaviour is unchanged. - `hooks/hooks.json` and `.mcp.json` are found by convention rather than declared, so nothing had checked them; declared paths already were. - The direct-skill branch checks containment. Only the recursive branch did, so a symlinked `skills/` was appended without a check. Crashes - A directory symlink cycle inside a plugin (`skills/a/loop -> ../..`) stays contained, passes every guard, and recursed until Python raised RecursionError during context construction. Visited directories are now tracked separately from discovered skills. - A non-string entry in `recommended-fields` raised TypeError from `field not in data`, which the linter turns into a rule crash — no manifest got validated at all. - `parsed.port` raises on `:not-a-port`; the port is only decoded on access, so nothing looked at it. Now validated with the rest of the URL. Correctness - `--type single-plugin` no longer discovers Codex content. Discovery ran before the override was installed, so the tree attached manifests, hooks and skills the override existed to exclude. - Duplicate-name detection compares normalised source identities. Raw JSON made `"./plugins/foo"` and `{"source":"local","path":"plugins/foo"}` look like different sources and reported a duplicate that was not one. - An inline `mcpServers` map is only unwrapped when the wrapper key is the sole key — a bare map may hold a server named `mcpServers`, and unwrapping on presence discarded every sibling. - Agent Skill autofix stands down on `.codex/plugins/*`. The checks still run, but `skillsaw fix` was free to rewrite a third-party SKILL.md and record the rename in this repository. Generated docs - Rendering is gated on a populated marketplace model rather than the primary repo type. A Codex catalog in a repo that is also APM or dot-claude lost the slot and fell to the single-page renderer. - Page filenames are collision-safe. Sanitising is lossy — `a/b`, `a:b` and `a-b` all reduce to `a-b.md` — and pages are keyed by filename, so one plugin silently replaced another while both index rows linked to the survivor. - `interface.category` is read, matching `interface.displayName`. - Remote catalog entries get a metadata-only doc, so the index stops reporting fewer plugins than the catalog lists. Validation: 3175 tests pass (20 new; 14 fail without these fixes). openai/plugins byte-identical at 6755 findings, docs still 181 files; openshift-eng/ai-helpers exit 0. Merged main.

2001 From: Stephen Benjamin Date: Sun, 26 Jul 2026 16:00:07 -0400 Subject: [PATCH 14/40] Close the remaining containment and allocation edge cases MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Eight findings from the Codex connector on 94262e3. Several are edge cases the previous round's fixes left open. Containment — two read paths bypassed discovery's boundary - `codex-marketplace-registration._check_entries()` reads the manifest itself, so discovery's containment does not cover it. A symlinked manifest put an external file's name into a violation message. - A skill directory can be contained while its `SKILL.md` is a symlink out. The directory was checked; the entrypoint was not. Allocation and normalisation — both mine from last round - Page filenames are allocated by probing a reserved set. Suffixing on a counter meant a generated `a-b-2.md` could collide with a plugin genuinely named `a-b-2`, and the later page overwrote the earlier. - Source normalisation strips exactly one leading `./`. `lstrip("./")` removes an arbitrary run of dots and slashes, so `./.plugins/foo` and `./plugins/foo` compared equal and a real conflict was suppressed. - Remote entries are collected from every catalog rather than the first. A repository that splits its listing across siblings lost the second file's remote-only entries entirely. Manifest arrays - `hooks`, `skills` and `mcpServers` permit one array level. The validator flattened recursively while discovery reads one level, so `[["./custom-hooks.json"]]` validated clean and never became a HooksBlock — executable commands passing every check and reaching no hook rule. Nested arrays are now reported as invalid values. Docs and autofix - A `PluginNode` does not imply a Claude plugin: legacy discovery creates one for any directory with `commands/` or `skills/`. A Codex-only plugin that also ships commands was misread as dual-ecosystem, so its docs fell back to the directory name and lost every manifest field. The two extractors now partition on a real Claude identity. - The registration autofix refuses a non-kebab manifest name. Writing one into the catalog traded a registration error for a naming error and published the identifier hosts use as the component namespace. The apostrophe-name test is split in two: one asserts such a name is now refused, the other keeps the original guard that fix() pairs violations by re-rendering check()'s message rather than parsing the name back out. Validation: 3184 tests pass (9 new; 7 fail without these fixes). openai/plugins byte-identical at 6755 findings, docs still 181 files; openshift-eng/ai-helpers exit 0.

charset=UTF-8 Content-Transfer-Encoding: 8bit Seven findings from the Codex connector on 291b609. Four are consequences of last round's fixes. Containment - A manifest must resolve inside *its own* plugin, not merely inside the repository. `plugins/a/.codex-plugin -> plugins/b/.codex-plugin` stays in the checkout, so the repo-wide check accepted it and plugin A was discovered and documented using B's manifest. Generated docs - The HTML renderer gates on the populated model like the Markdown one. Only Markdown was changed last round, so a Codex catalog in an APM or dot-claude repo still lost the grid, navigation, category filter and search. - Filenames are reserved case-folded. `Foo.md` and `foo.md` are one file on default macOS and Windows installs, so the exact-case set handed out both and the second page overwrote the first. - Codex remote entries are merged even when a Claude marketplace supplies the catalog identity. The `elif` meant a repository with both formats dropped every remote-only Codex entry. - A malformed local source is no longer published as a remote one. `{"source": "local"}` with no path yields `None` from `codex_local_source_path`, which the remote branch read as "not local" and advertised a page for a plugin Codex skips. - Hooks and MCP docs are read from the legacy `PluginNode` as well as the Codex node. For a plugin shipping `commands/`, legacy discovery claims `hooks/hooks.json` and `.mcp.json` first and the tree's `seen` set keeps them off the Codex node — so moving metadata to the Codex extractor last round left those two behind. Autofix - A name the catalog already spells is not advertised as fixable. `fix()` refuses to append a duplicate name, so the offer was a no-op that left the violation standing after the user applied it. This needed its own name set: `_registered()` deliberately ignores local entries' names. Validation: 3191 tests pass (7 new; 6 fail without these fixes). openai/plugins byte-identical at 6755 findings, docs still 181 files; openshift-eng/ai-helpers exit 0.

Security - Skill `references/` files are containment-checked against the owning Codex plugin. Only the skill directory and SKILL.md were, so a plugin could symlink a reference out of the checkout — and the SAFE content fixes rewrite these files in place, so `skillsaw fix` would have written through it. - The generated HTML escaped values into inline `onclick` handlers with an entity-encoded quote. `innerHTML` decodes entities *before* the handler compiles, so the quote came back live and a crafted category such as `x');alert(document.domain);//` executed on click. Values are now escaped for the JS context first, then for HTML. Pre-existing — Claude categories flow through the same path — but Codex categories and the wider marketplace rendering made it reachable from a new input. Discovery - A document declared as both `hooks` and `mcpServers` is attached twice. `seen` is keyed by path, so the hooks attachment claimed it and the servers reached neither MCP rule. Fixed narrowly rather than by rekeying the shared set: `(path, type)` looks more correct but weakens the plugin-contributor duplicate guard and promptfoo fragment sharing, both of which depend on path identity. - A dangling in-repository catalog symlink stays discovered, so the rule reports it instead of the repository silently losing its type. Rules and config - `OpenclawMetadataRule` carries its own host-type list, so Codex-hosted skills were skipped by it even after the shared set was widened. - A non-iterable `installation-values` / `authentication-values` raised TypeError from the membership test, crashing the rule mid-catalog. - `.pre-commit-hooks.yaml` triggers on the Codex discovery inputs (`.codex-plugin/`, `.codex/plugins/`, `.agents/plugins/*.json`). With `pass_filenames: false` a commit touching only those skipped skillsaw entirely, contrary to what the hook documents. Generated docs - Codex-only classification keys off what discovery accepted rather than a raw `is_file()`, which followed a rejected symlinked manifest and dropped the plugin from the docs altogether. - `_BlockSources` deduplicates by node identity: a legacy PluginNode has the Codex node as a descendant, so inline hooks and servers were listed twice. - Legacy nodes are indexed once instead of rescanned per Codex plugin, which was O(codex x legacy) filesystem resolutions. - The `skills` field takes directory paths, not inline config — the docs promised an inline form that discovery never reads. Validation: 3208 tests pass (17 new; 12 fail without these fixes). openai/plugins byte-identical at 6755 findings, docs still 181 files; openshift-eng/ai-helpers exit 0.

nested-plugin attribution MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Six findings from the Codex connector on 427ce62. Three follow from last round's fixes. Security - `homepage` and `repository` are dropped unless they use a safe scheme. HTML-escaping an href stops attribute breakout but does nothing about the scheme, so `javascript:` in a manifest a marketplace merely accepted would run script in the docs origin when a reader clicks through. Second instance of this shape after the inline-handler escaping, and the same root cause: escaping for the wrong context. Consequences of the previous round - The conventional `.mcp.json` is seeded into the Codex MCP set. The second-attachment fix read every claimed path as needing another MCP interpretation, so a manifest declaring `"mcpServers": "./.mcp.json"` got two blocks and doubled every violation and doc entry. - `recommended-fields` is normalised when the *setting itself* is not a list. Last round guarded each entry, but a scalar fails at the loop before that guard runs, and config loading does not enforce `config_schema` types — so the rule crashed for every manifest. - `plugin-json-required` decides Codex identity from contained discovery rather than a raw `is_file()`. With a manifest symlinked out of the plugin, discovery rejects it, so no Codex rule covers the directory — and the Claude rule was standing down too, leaving it unreported by anything. Generated docs - A nested plugin's skills go to the nearest containing plugin root. When the repository root is itself a plugin, everything under `plugins/` is relative to both roots, so the root's page duplicated and misattributed every nested plugin's skills. - Windows reserved device basenames are suffixed. `con`, `nul`, `com1` and friends stay reserved with an extension, so `con.md` cannot be created and generation failed for the whole catalog on Windows.

Escape attribute values with an attribute-context escaper: esc() serialises a text node and leaves the double quote intact, which closes an attribute and lets a second handler follow it. - Keep evals/evals.json inside its owning Codex plugin. The rules read and rewrite it, so a symlink out of the plugin is a read and a write outside the checkout. - Attribute nested content to the nearest owning plugin, not the first matching root. - Stand rename-refs autofix down on skills installed under .codex/plugins/, matching the rest of the authored-vs-installed line. - Register a catalog entry by name only when its source is genuinely remote. A malformed entry names nothing installable, and crediting it silenced the unregistered report for a real directory. - Advertise agentskill-name fixability honestly on installed skills, where fix() already stood down. - Resolve the Codex roots once per docs extraction instead of once per legacy plugin node. - Keep a plugin whose .codex-plugin is a regular file or a dangling symlink: the reserved name is occupied either way, and discarding it un-typed the repository so nothing reported the broken entrypoint. - Reserve README.md so a plugin named "readme" cannot be overwritten by the index page.

Address panel verdict and review round eleven Blocking: - Guard the stat() calls that follow safe_resolve. Path.resolve() does not stat, so it returns a path that the next is_dir() raises on, and pathlib swallows ENAMETOOLONG only from Python 3.13 on. On 3.9-3.12 a manifest declaring a 4000-character path aborted the whole lint from inside RepositoryContext.__init__, where the rule-execution-error guard cannot reach it: traceback, exit 1, nothing reported. Correctness: - Build the HTML page from the catalog's membership, as the Markdown renderer does. A remote-only catalog rendered an empty grid. - Derive catalog membership from the catalog's plugins array rather than from everything discovery found; a dot-claude repo published .claude itself as an entry. Overlay each listing's category onto the matched plugin, which is where the field usually lives. - Filter discovered catalogs through the exclusion predicate. The lint tree filtered them; skillsaw docs read the list directly. - Keep an installed plugin's skills out of the standalone-skills pass. Skipping the plugin left its skills matched by no PluginDoc, so they were published as this repository's own content. - Read the Claude rules' Codex stand-down from the filesystem, not from repo_types or from discovery. Both are switched off by an explicit --type, so --type marketplace resurrected on a Codex repo the exact false positives the stand-down exists to remove. - Reject a non-string hook type before the set membership test. A list-valued type raised TypeError and took hook validation for every remaining block with it. - Match sibling catalogs on a name boundary; a bare endswith claimed notamarketplace.json. Compare the primary by resolved path so a case-insensitive filesystem does not list it twice. - KEBAB_CASE anchors with \Z. "$" also matches before a trailing newline, so "my-plugin\n" passed and the autofix published it. - Coerce sort keys with name_str; a list-valued name raised TypeError. - Report a non-object interface, which every check below silently skipped. Structure: - Move the eight stateless codex_* methods off RepositoryContext into formats/codex.py as free functions over a plugin_dir, and import them there rather than through context's re-export. - Type the new helpers; drop a noqa on an import used seven lines down. Tests and docs: - CLI-level autofix coverage through Linter.fix_and_apply, including BOM and CRLF preservation and the whole-file reserialisation, which is pinned rather than endorsed. - commands/ and a README in the clean fixture, so plugin-json-required iterates something and its stand-down is actually guarded. - Malformed catalog and manifest shapes; the visible plugins/* symlink case, with the pre-existing agentskills-walk gap marked xfail. - Document the Codex stand-down on both affected rule pages; correct the sibling-discovery condition and the claim that policy.authentication is undocumented; add Codex to the maintenance skill's description.

Both parse nested containers recursively, so a document nested past the stack limit raises rather than returning a decode error — and discovery reads these files inside RepositoryContext.__init__, outside the rule-execution-error guard, so the whole lint aborted with a traceback and reported nothing. The two direct yaml.safe_load calls on the lint-tree path are guarded the same way. - Put six source comments and five test docstrings in the conditional. Each described, in the past tense, a defect that existed only between review rounds; no reader of shipped code can find the state they narrate. - Correct references/codex.md in all three copies. openai/codex ships a field-level spec inside the plugin-creator skill that is stricter than the prose spec: it requires strict semver, enumerates ON_INSTALL / ON_USE, and documents logoDark. The deliberate non-checks stand, but now record "we choose not to enforce this" rather than "no such constraint exists" — the maintenance skill treats them as binding, so a wrong rationale would lock in a refusal on a false premise. Also: - Bump to 0.18.0 so the rules' `since` names a version the package claims. This does not change which rules run: a default lint already enabled all four, and only a config pinning an older version skips them, which is what `since` is for. - Invalidate the catalog memo in apply_excludes; a caller adding patterns afterwards kept reading a catalog it had just excluded. - Memoize the resolved install root, which was re-resolved once per SkillNode. `make benchmark-compare` against a main baseline reports no regressions. - Drop the dead imports this branch introduced, the unused laundered RepositoryType in openclaw/metadata.py, and the paths.py docstring claim that the import edge it describes is unique.

Python 3.14 raises on measured stack usage rather than a depth counter, so the depth that overflows depends on the thread's stack size, and setrecursionlimit does not constrain the C scanner. They now inject the error, which is the contract the guards actually make: a RecursionError from the parser becomes an error string, on every version. Review findings: - Exempt a repository whose only catalog is a sibling such as api_marketplace.json. The exemption asked about the primary filename alone, so the layout openai/plugins itself uses reported "Marketplace file not found". Asked of the filesystem, not of discovery, which an explicit --type switches off without changing whether the catalog is Codex's. - Rediscover Codex plugins when excludes are applied after construction. Dropping the memo was not enough: a plugin reachable only through a now-excluded catalog has no excluded path of its own, so filtering kept it and its manifest, hooks, MCP config and skills stayed in the tree. - Coerce a hook matcher to a string at the block boundary, and report the bad shape. A list-valued matcher reached the generated docs page, where searching lowercases it and stops rendering. - Memoize the resolved Codex roots. codex_plugin_owning runs once per skill inside two rules, so every lookup re-resolved every root. benchmark-compare against a main baseline: no regressions. Not taken: removing the hand-written imports from rules/builtin/codex's package initializer. All seven builtin rule packages re-export their rules exactly this way; codex is consistent with them, and dropping it would make it the only one that is not.

The marketplace seed is reachable from fix_and_apply, so a symlinked catalog let the registration autofix rewrite a file outside the checkout. The plugin seed re-added a .codex-plugin marker discovery had already rejected for resolving out of the repository. - Drop anchors with an active scheme when rendering markdown. html.escape stops a link target breaking out of the attribute and says nothing about what the target is, so a skill description carrying [x](javascript:...) produced a live anchor in a page inserted through innerHTML. - Classify an install by the path it was reached through, not the path it resolves to. A symlinked .codex/plugins entry read as authored, which published it and let autofixes rewrite it. - Stop excluding a manifest from taking the plugin's hooks.json and .mcp.json with it. Those have their own paths and their own exclusion check, and dropping them put executable configs out of reach of hooks-dangerous, hooks-prohibited and the MCP rules. Robustness — malformed input must not abort a run: - Non-string allowed-tools entries, mapping-valued skill names, a non-list plugins array, and an unhashable source discriminator all reached the docs generator or a frozenset test and raised. - The registration rule reparses raw text, so it needed the same RecursionError guard the shared reader already has. - agentskill-unreferenced-files, newly active on Codex skills, resolved link targets with a bare resolve(); a symlink loop raises RuntimeError before 3.13 and discarded every finding. - Reject drive-relative Windows paths (C:plugins\evil): a drive with no root resolves against that drive's current directory. Correctness of the record: - mcpServers accepts an inline object. plugin-json-spec.md types the field "string or object" and shows the inline form in a worked example, so warning on it was the false-positive class these rules exist to remove. - Stop asserting that upstream does not constrain version, and that logoDark and the interface assets are undocumented. That spec documents all of them. The non-checks stand as choices. - Rediscovery after a late exclude now also prunes skills the departed plugins contributed, and the exemption probe recognises a duck-typed catalog the way discovery does. Also drops the module-scope rule-package import from linter.py, which doubled CLI startup on every invocation and broke the layering the module-layering test exists to protect; the context already answers the question directly.

Claude types still outrank Codex ones, so dual-ecosystem output is unchanged. - Guard escAttr against undefined/null so an omitted category or homepage renders as empty instead of the literal "undefined". - Report the document root line when openai.yaml is not a mapping, via a new commented_root_line() helper; plain scalars carry no position and keep omitting the line rather than fabricating one. - Route MCP table cells through _table_cell so a command containing '|' or a newline cannot corrupt the generated Markdown table. - Reject NaN/Infinity/-Infinity in codex-marketplace-json-valid with the same strict constant handling the registration fixer already uses, sharing reject_nonfinite_json_number from codex/_helpers. - Restore the .claude repository input in the docs CLI help alongside the Codex wording. - Clear fix_confidence with fixable on vendor-managed violations so JSON/SARIF cannot keep advertising SAFE/SUGGEST. - Hoist SKILL_REPO_TYPES to skillsaw.context so openclaw and codex rules stop importing the agentskills package's private helpers. - Use safe_exists in contained_skill_file, bind the containment root explicitly in _contained_in_plugin, reuse the context's cached codex_plugin_owning in the lint tree, derive the Codex block root from plugin_dir, and rename the extractor's shadowed codex_roots binding. - Document _has_claude_plugin's marker-directory semantics: the empty ``.claude-plugin`` case is deliberate and pinned by an existing test, so the behavior stands and the misleading docstring is corrected. - Harden the module-layering test to catch imports nested in top-level try/if blocks, and assert block attachment in the Codex-scoping regression tests so they cannot pass vacuously.
