Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This documentation-only ADR changes the proposed skill delivery contract, but its current text conflicts with the existing SkillCard API and includes concrete assembly and platform-compatibility gaps: conflicting sources can be silently accepted, the loader mount is read-only, inline size and skill-name validation are undefined, and ImageVolume support is misstated. Those issues could lead to invalid resources or failed deployments if implemented as written, so the PR is not merge-ready until corrected or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Proposes dropping skillctl for an ordinary Containerfile, letting one image carry a bundle of skills, and assembling /opt/skills in an init container that validates what it assembled. Inline and git sources stop needing an image at all: inline becomes a ConfigMap, git is cloned at pod start, and the controller still builds nothing. skillctl was already producing a plain OCI image from a directory, and charging us a `skill.yaml` that duplicated the SKILL.md frontmatter. `skillctl install --target goose` isn't supported at v0.7.2 either, so the local dev story ADR 0001 promised was never reachable. Cloning git at pod start is the thing ADR 0001 rejected as "pallet as runtime sync engine", so 0015 supersedes that explicitly rather than contradicting it quietly, and takes the loss: a git source needs the network at startup, isn't auditable by digest, and doesn't work air-gapped. That's bounded to `spec.source`, and the remedy is to build the repo into an image. Image and inline still need no network at pod start, so ADR 0001's air-gap requirement is scoped rather than overturned. Resolving git controller-side into a ConfigMap would remove the cost and stays open: `spec.source` means the same thing either way, so it can be adopted later without an API change. Also supersedes ADR 0001's packaging section, keeps its mount contract, and revises where ADR 0014 sources its rules list, since `KONVEYOR_RULES` set from `spec.type` can't work for a bundle: the controller never sees inside the image, so it can't say which of the skills is a rule. konveyor#135 needs updating alongside this if the decision holds. One question is left open rather than settled: whether a SkillCard should be able to demote a skill whose frontmatter declares it a rule. Promotion is harmless, demotion turns a constraint into a suggestion, which is what ADR 0014 rejected an alternative over. Lists the docs in CONTEXT.md and README.md that stop being true, to be updated when the implementation lands rather than now. A prototype of all of it exists and produced the measurements quoted in the ADR, on minikube with CRI-O 1.35.0 and k8s v1.34.0. It's held back pending review of the decisions.

Strong ADR — the reasoning is careful, the code and ADR-0014 citations check out (verified against the tree; several are verbatim with exact line numbers), and the prototype measurements are real. Dropping skillctl, the Containerfile approach, and delivering inline/git without an in-cluster registry are all the right calls for dev-preview.
Requesting changes on one primary point, with a few smaller follow-ups.
Primary: unify "bundle" and SkillCollection under one term. The ADR introduces "bundle" (one OCI image carrying many skills) as a new concept but never reconciles it with SkillCollection, which already means "a group of skills." Two terms for closely related ideas is confusing language we should avoid, and "bundle" isn't in CONTEXT.md. Since SkillCollection is currently unused scaffolding (one sample, referenced by no Agent, in no e2e path), we can reshape it freely. Let's keep the name collection and make it meaningful by absorbing the ideas in this ADR: a SkillCollection is a set of skills resolved from one or more sources — a list of refs (as today), a git repo containing many skill dirs, or an OCI image containing many skill dirs. That last shape is what this ADR calls a "bundle" — so bundle becomes an implementation detail of a SkillCollection image source, not a parallel concept. That also gives SkillCollection a real reason to exist: "one source → many skills," which a plain list of refs can't do.
This has a knock-on effect that simplifies the ADR: with type staying on the CRD (SkillCard spec.type per skill; SkillCollection a uniform source-wide policy), the §8 frontmatter-type change and the entire demotion open question can be dropped. See the inline comment on §3 for the full argument, including why frontmatter type is incompatible with validating skills against agentskills.io.
Please reconcile the ADR text around this and update the CONTEXT.md SkillCard/SkillCollection entries in this PR — the ADR's own "Documentation this invalidates" section already lists those lines.
Inline comments cover the details plus five smaller items (a #135/#138 reference fix, extracting a shared validation package, an author-facing validator, confirming the git-at-pod-start reversal, and a status-observability nit).

| ### 3. One image may carry one skill or many, and the shape is detected |
There was a problem hiding this comment.
This is the crux. "Bundle" (one OCI image, many skills) is introduced here but never reconciled with SkillCollection, which already means "a group of skills." The Consequences line "SkillCollection gains a physical form. One image, one pull, one signature" gestures at the overlap but leaves two terms unreconciled, and "bundle" isn't in CONTEXT.md.
There's also an internal contradiction with validation. Decision §6 puts a validator in the loader that checks every skill's frontmatter at init, and CI validates against agentskills.io. That spec defines a closed set of top-level frontmatter fields (name, description, license, compatibility, metadata, allowed-tools) and its reference validator rejects anything else. So §8's "type becomes a frontmatter key" would be rejected by this ADR's own loader: a top-level type: fails validation. The only compliant home is metadata.konveyor.io/type, an inert private convention every other agentskills.io client ignores. (Also: the ADR calls license/metadata "non-standard" precedent — both are standard spec fields, so they aren't precedent for non-standard keys.) Frontmatter is the wrong place for type the moment we commit to validating skills.
Proposal (SkillCollection is unused scaffolding, so we can reshape freely): don't make "bundle" a domain concept. Make it the packaging shape of a SkillCollection image source.
- SkillCard = one skill.
spec.typestays on the CR — validated, observable, per-skill — and SKILL.md content stays pure, passing our own validator. - SkillCollection = a set of skills from one or more sources: a list of refs, a git repo with many skill dirs, or an OCI image with many skill dirs (the "bundle").
On type: single skills keep type on the SkillCard CR (common case, solved). A multi-skill source resolves to a uniform source-wide load policy on the SkillCollection. Mixed skill/rule within one source is the only case needing per-skill frontmatter, and that's deferred. This lets §8's frontmatter-type change and the demotion open question be dropped entirely: nothing to demote because content never declares a type, and our validator never has to accept a non-standard key.
Keeps the name, keeps type on the CRD, keeps agentskills.io compliance consistent with our own validation, and supports the multi-skill-image packaging you want. Please reconcile the ADR and update the CONTEXT.md SkillCard/SkillCollection entries in this PR.
There was a problem hiding this comment.
took the type finding, pushed back on the merge.
you're right about the validator. skills-ref/src/skills_ref/validator.py errors on anything outside ALLOWED_FIELDS, so a top-level type: would fail the format decision 1 adopts. and my precedent claim was just wrong, license and metadata are both standard fields. so frontmatter type is gone, it's back on the CRD, kubebuilder default restored, and the demotion open question is dropped.
I got there with subPath instead of folding into SkillCollection though. a card selects one skill out of an image, so it means one skill again and spec.type is per-skill without needing a source-wide policy. that keeps a mixed skill/rule image working rather than deferring it.
on the merge itself I think packaging and grouping are independent axes. a collection can list skills from three vendors' images, and an Agent can want one skill out of a four-skill image. merging them forces lockstep versioning on skills that don't need it and lets a vendor's packaging decide an operator's grouping. §3 has the argument.
you're right that "bundle" shouldn't be a domain term, that's gone. and "one source, many skills" being a real job for SkillCollection is now an open question, probably where it ends up, with the controller enumerating a source and spawning a SkillCard per skill. CONTEXT.md entries updated here as asked.

#135 is the tracking issue, not the PR. The ADR 0014 document lives on PR #138 (which closes #135). This should be #138 in three spots: here in the numbering note, the §8 revision paragraph, and the closing "#135 needs updating alongside this." The "still open / proposed" characterization of ADR 0014 is correct — just the number is off.

There was a problem hiding this comment.
The "third caller" you're deferring against already exists in the plan: an author-facing konveyor-skills validate binary (see the §6 comment), plus make skill-validate in CI — that's the controller (inline), the loader (init), the standalone validator, and CI all applying the same frontmatter rules.
I'd extract validation into a shared package now rather than defer it. The harness is a separate Go module (harness/go.mod), which is why the controller can't import it today — so the shared package needs a home both modules depend on (its own module, or a pkg/ the harness requires). "Deliberately the looser of the two" implementations drifting is exactly the validation gap ADR 0014 flags as load-bearing. One source of truth for "what is a valid skill" is worth the module plumbing.
There was a problem hiding this comment.
agreed on the principle, named it as scope in §6 rather than doing it here. the plumbing is real since harness/ is its own module, so it needs a home both can import, and I didn't want that in an ADR-only PR. lands with the implementation.

| ### 6. Validation lives where the bytes are |
There was a problem hiding this comment.
Validation here covers our runtime (loader) and CI (make skill-validate), but not the "pattern for others to emulate" case — an external author building their own skill image who wants to check it before publishing. The loader validates at pod-init (too late for them), and make skill-validate is repo-internal.
Consider a standalone go install github.com/konveyor/agentic-controller/cmd/konveyor-skills@latest with a validate <dir> subcommand, sharing the package from the previous comment. Now that anyone can build a skill image with a plain Containerfile, the low barrier to building raises the value of an easy way to check it's correct. Could be a follow-up rather than in this ADR, but worth naming as intended scope so it isn't lost.
There was a problem hiding this comment.
yes, in §6 as intended scope now. agree the low barrier to building a skill image is exactly what raises the value of an easy way to check one.

| ### 4a. Git is resolved at pod start, superseding ADR 0001's rejection of it |
There was a problem hiding this comment.
Flagging as a decision to confirm, not an objection. Earlier design discussion leaned toward controller-side git resolution (clone at reconcile → ConfigMap) specifically to preserve ADR 0001's determinism/air-gap properties rather than supersede them. This ADR goes the other way: runtime clone, controller-side deferred.
The reasoning is sound — controller-side needs egress + a git client + private-repo creds in the reconciler, plus the ConfigMap tar-packing ceiling — and you've kept it reversible behind an unchanged API (spec.source/ref/subPath mean the same either way). Defensible for dev-preview. Just putting on record that we're accepting the air-gap/latency loss on git sources deliberately, with "build it into an image" as the primary path. No change requested if that's the intent.
There was a problem hiding this comment.
confirmed, deliberate. 4a supersedes ADR 0001's pallet as runtime sync engine rejection explicitly now instead of quietly contradicting it, and takes the loss: no air-gap, no digest audit, clone time at startup. bounded to spec.source, and building the repo into an image is the way out. controller-side resolution stays open and spec.source/ref/subPath mean the same either way, so adopting it later isn't an API change.
| | `source` | the loader clones at pod start | nobody | | ||
|
|
||
| The controller gains no builder, no in-cluster registry, no push | ||
| credentials and no network egress of its own. `status.resolvedImage` is now |
There was a problem hiding this comment.
With resolvedImage empty but Ready=True for inline/git, a reader of SkillCard status can't distinguish "resolved to nothing yet" from "resolved, just not to an image." Consider a status condition or a small enum (e.g. status.deliveryMode: image|inline|source) so the resolved state is observable without inferring from an empty field. Minor — observability, not correctness.
Make a SkillCard mean one skill again, selecting out of a multi-skill image with subPath, so `type` stays on the CRD instead of moving into frontmatter. The review caught why that mattered: the Agent Skills field set is closed and skills-ref errors on anything else, so a top-level `type:` would have failed the standard decision 1 adopts, and the draft's claim that `license` and `metadata` were precedent for non-standard keys was wrong since both are standard fields. That drops the demotion open question entirely and lets the kubebuilder default come back. Drop "bundle" as a term, and argue in §3 against folding multi-skill images into SkillCollection, since packaging and grouping vary independently and a uniform per-source policy cannot express a mixed set. Replace the dropped open question with two: whether SkillCollection should be the type users write with SkillCards generated from it, and how a source gets enumerated. The obvious objection to enumeration does not hold, since the kubelet must pull the image to run the skill anyway, so a pod mounting it the way the loader does can enumerate it with nothing new asked of the reconciler. Fix konveyor#135 to konveyor#138 for ADR 0014, note that our validator is looser than the spec's name rules, name the shared validation package and an author-facing validate command as scope, and add status.deliveryMode. Update the CONTEXT.md SkillCard and SkillCollection entries here rather than with the implementation, since the glossary is meant to be canonical. Found while doing it: CONTEXT.md:21 says the controller creates SkillCards for git-sourced entries, and no controller does.

- Line 359: Correct the misspelled occurrence of “cadence” in the documentation
text, without changing the surrounding meaning or formatting.
- Around line 368-371: Update the Decision 8 consequences in the ADR to remove
or rewrite the stale spec.type statement: preserve that SkillCard.spec.type
retains the skill default, and describe subPath selecting an individual skill
rather than claiming the default is lost or that every source skill becomes
on-demand.
- Around line 119-125: Enforce exactly one of the image, inline, or source
fields at the API boundary using CRD validation or a validating webhook. Update
the SkillCard schema around the fields in SkillCardSpec and ensure the
skillcard_controller reconciliation path cannot accept conflicting
configurations or silently ignore additional sources.
- Around line 176-195: Update the manifest sketch’s skill-loader volume mounts
so the shared skills volume is mounted at /opt/skills with write access for
skill assembly, while preserving the agent container’s existing read-only mount.
- Around line 78-83: Update the ADR’s SkillCard examples and surrounding claims
to match the existing SkillCardSpec API: remove subPath-based image selection
and any unsupported ref usage, reflecting that AgentRun mounts
status.resolvedImage without subpath selection. Do not document this behavior
unless the corresponding API and controller plumbing is implemented.
- Around line 323-325: Align the ImageVolume compatibility statements in the
ADR: consistently specify the supported Kubernetes version and feature-gate
requirement, clarify the failure or fallback behavior on unsupported clusters,
and correct the conflicting “ImageVolume GA” claim in the platform requirements.
- Around line 365-367: Update the ADR’s inline skill packaging guidance to
require validating spec.inline content below Kubernetes’ 1 MiB ConfigMap limit
before creating the ConfigMap, and define the failure behavior for oversized
content; alternatively specify a different transport for content exceeding that
bound.
- Around line 273-277: Update skill loading before assembly to reject any skill
whose frontmatter name differs from its source parent directory, rather than
logging the mismatch or renaming the skill. Ensure the failure identifies the
mismatched name and source origin, while preserving duplicate-name handling for
valid skills.

Update the examples or add the required API and controller plumbing before documenting this behavior.

Enforce exactly one source at the API boundary.
This table defines image, inline, and source as mutually exclusive. api/v1alpha1/skillcard_types.go:40-77 declares independent optional fields. internal/controller/skillcard_controller.go:48-89 selects the first non-empty field and silently ignores the others. Add CRD validation or a webhook that requires exactly one source. Reject conflicting objects instead of ignoring part of their configuration.

Mount /opt/skills writable in skill-loader.
The manifest sketch shows the skills volume only for the agent and marks it read-only. The loader must write the assembled tree before the agent starts. Add a writable skills mount to skill-loader, while keeping the agent mount read-only.

Official Agent Skills specification directory name must match frontmatter name validation assembled skill directory source artifact
💡 Result:
According to the official Agent Skills specification, the name field defined in the YAML frontmatter of the SKILL.md file must strictly match the name of the parent directory containing the skill [1][2][3]. Specifically, the Agent Skills specification enforces that: 1. The skill name must be a string of 1-64 characters [1][2][3]. 2. It must consist only of lowercase alphanumeric characters (a-z, 0-9) and hyphens (-) [1][2][3]. 3. The name cannot start or end with a hyphen and cannot contain consecutive hyphens [1][2][3]. 4. Critically, for the skill to be considered valid and compliant, this frontmatter name must be identical to the directory name in which the SKILL.md file resides [1][2][4][3]. Tooling designed to validate skills, such as specialized linting utilities or framework loaders, typically performs this check by reading the SKILL.md file, extracting the frontmatter, and comparing the name property against the directory path of the file [1][5][4][3]. While some implementations may offer "lenient" modes that only warn upon a mismatch rather than failing, the core specification mandates this alignment as part of the formal validation rules for an assembled skill directory [6].

Kubernetes ImageVolume feature gate minimum Kubernetes version feature state v1.34 official documentation
💡 Result:
The ImageVolume feature gate was in the beta state during the Kubernetes v1.34 release [1][2]. The feature followed this progression: - Introduced as Alpha in Kubernetes v1.31 [3][4]. - Graduated to Beta in Kubernetes v1.33 [3][5]. - Remained in Beta throughout the v1.34 release cycle [1][2]. - Ultimately reached General Availability (GA/stable) in Kubernetes v1.36 [6][7]. In v1.34, because the feature was in beta, it was not enabled by default and required manual activation via the ImageVolume feature gate [3][8]. The minimum Kubernetes server version to use the feature is v1.31 [9][10].

Kubernetes ConfigMap maximum size 1 MiB official documentation
💡 Result:
The official Kubernetes documentation specifies that a ConfigMap is not designed to hold large chunks of data and states that the data stored in a ConfigMap cannot exceed 1 MiB [1]. This limit applies to the entire ConfigMap object, including its metadata and all key-value pairs [2][3]. The 1 MiB limit is primarily enforced because Kubernetes stores these objects in etcd, which has its own underlying request size limitations [2][3]. While some etcd configurations may allow for larger request sizes, Kubernetes maintains this constraint for ConfigMaps to ensure cluster performance and stability [2][3][4]. If your data exceeds this 1 MiB threshold, the following strategies are recommended by the community and official guidance: * Split the configuration into multiple smaller ConfigMaps [1][2][4]. * Use a volume mount (e.g., from an external file service or object storage) to provide the data to your Pods [1][3][4]. * Use a separate database or key-value store for larger datasets [1][2]. * Compress the data (if applicable) before storing it, though this may not be sufficient for very large files [5][3]. It is important to note that when defining a ConfigMap in a YAML manifest, the practical limit may be lower than 1 MiB. Factors such as base64 encoding for binary data, YAML whitespace, and metadata overhead consume space within that 1 MiB budget [3].

Correct the stale spec.type consequence.
Decision 8 keeps spec.type on each SkillCard, keeps the skill default, and uses subPath to select one skill. This bullet says the default is lost and pins every skill from the source. Remove or rewrite it because it describes the rejected whole-source model.

the Decision 8 consequences in the ADR to remove or rewrite the stale spec.type
statement: preserve that SkillCard.spec.type retains the skill default, and
describe subPath selecting an individual skill rather than claiming the default
is lost or that every source skill becomes on-demand.

Approving — the revision addresses all six review items and the ADR is in good shape.
- Bundle / SkillCollection /
type. Resolved better than my original ask. Rather than folding a multi-skill image into SkillCollection,subPathon a SkillCard selects one skill from a multi-skill image, so a card always means one skill andtypestays a per-skill CRD field — the frontmatter-typechange and the demotion question are gone. The packaging-vs-grouping framing is the right call: they're independent axes, and merging them would force lockstep versioning and let a vendor's packaging dictate an operator's grouping. "Bundle" is now a fact about an artifact, not a domain term. #135→#138— fixed throughout.- Shared validation package — §6 "one implementation, four callers," with the Go-module plumbing named.
- Author-facing validator —
konveyor-skills validate <dir>named as intended scope. status.deliveryMode— added for observability.- git-at-pod-start — confirmed as a conscious, scoped reversal of ADR 0001.
- Nice catch adopting the correction that
license/metadataare standard Agent Skills fields, and updating CONTEXT.md in this PR.
The remaining items are genuine open questions appropriate for a proposed ADR, not blockers. In particular, "should SkillCollection be the type users write, with SkillCards generated?" is well framed, and the enumeration-via-short-lived-loader-pod answer neatly avoids putting a registry client in the reconciler while staying API-compatible with today's image + subPath (a generated card is just that). Good sequencing: decide subPath now, keep generate-from-collection as tracked future work.
My prior CHANGES_REQUESTED was against the pre-force-push commit; this supersedes it.

Proposes dropping skillctl for an ordinary Containerfile, letting one image carry a bundle of skills, and assembling
/opt/skillsin an init container that validates what it assembled. Inline and git sources stop needing an image at all: inline becomes a ConfigMap, git is cloned at pod start, and the controller still builds nothing.skillctl was already producing a plain OCI image from a directory, and charging us a
skill.yamlthat duplicated the SKILL.md frontmatter.skillctl install --target gooseisn't supported at v0.7.2 either, so the local dev story ADR 0001 promised was never reachable.Cloning git at pod start is the thing ADR 0001 rejected as "pallet as runtime sync engine", so this supersedes that explicitly rather than contradicting it quietly, and takes the loss: a git source needs the network at startup, isn't auditable by digest, and doesn't work air-gapped. That's bounded to
spec.source, and the remedy is to build the repo into an image. Image and inline still need no network at pod start, so the air-gap requirement is scoped rather than overturned. Resolving git controller-side into a ConfigMap would remove the cost and stays open:spec.sourcemeans the same thing either way, so it can be adopted later without an API change.Also revises where ADR 0014 sources its rules list.
KONVEYOR_RULESset fromspec.typecan't work for a bundle, since the controller never sees inside the image and so can't say which of the skills is a rule. #135 needs updating alongside this if the decision holds.One question is left open rather than settled: whether a SkillCard should be able to demote a skill whose frontmatter declares it a rule. Promotion is harmless, demotion turns a constraint into a suggestion, which is what ADR 0014 rejected an alternative over. I'd like a second opinion on that one before it hardens.
The ADR lists the docs in CONTEXT.md and README.md that stop being true. They aren't touched here on purpose: this merges as
proposedwith no implementation, so those docs still describe the system as it actually is, and editing them now would make them wrong.A prototype of all of it exists and produced the measurements quoted in the ADR, including the four-case probe on minikube with CRI-O 1.35.0 and k8s v1.34.0. It's held back pending review of the decisions, so this PR is the ADR alone.
