351-361: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winClarify whether ADR 0014 supersedes part of ADR 0001.
This ADR states that ADR 0001's runtime-discovery statement is false, but also says ADR 0001 is not superseded. Keep ADR 0001 unchanged and state that ADR 0014 supersedes only that statement, or explain why it was never a decision. This prevents conflicting architecture contracts.
As per coding guidelines: “Accepted ADRs are immutable; create a new ADR that supersedes an existing decision instead of editing the original.”

cards explicitly as constraints, ensure the rollout is blocked until migration

- Around line 182-185: Update the skill-loading and session-creation flow
described by the ADR to reject duplicate frontmatter `name` values across
SkillCards before a session is created, rather than selecting an artifact by
walk order. Enforce a single stable identity and return a clear error
identifying the duplicate name and conflicting cards.
- Around line 189-194: Update the skill-loading policy section in the ADR to
explicitly address repository skill shadowing: document a mitigation such as
collision detection/rejection or state that untrusted cloned repositories are
outside the deployment trust model. Ensure the policy covers same-name
frontmatter collisions between repository and mounted skills before native mode
becomes the default.
- Around line 109-113: Update the controller’s rule-card environment assembly to
explicitly set KONVEYOR_RULES to an empty value when no type: rule cards exist,
while preserving populated values for discovered rules. Use presence-aware
lookup so unset, empty, and populated KONVEYOR_RULES states remain
distinguishable, and add coverage for all three cases.

💡 Result:
The document 0014-skill-loading-and-prompt-assembly.md is associated with the konveyor/agentic-controller project, which utilizes architecture decision records (ADRs) to document its design [1]. Within this project, Skills are defined as individual rules or capabilities that resolve to OCI artifacts mounted at /opt/skills/{name}/ [1]. The controller operates by having an Agent declare available skills, gateways, and prompt parameters, while an AgentRun provides the concrete values to trigger execution [1]. KONVEYOR_RULES appear to be a conceptual or internal naming convention within this agentic framework used for managing these skills and the resulting prompt assembly during the orchestration process [1].

🌐 Web query:
https://raw.githubusercontent.com/konveyor/agentic-controller/main/docs/adr/0014-skill-loading-and-prompt-assembly.md KONVEYOR_RULES unset empty
💡 Result:
In the context of the Konveyor Agentic Controller project and its architecture decision records (such as ADR 0014 regarding skill loading and prompt assembly), the phrase KONVEYOR_RULES unset empty refers to the handling of environment variable configuration [1][2]. Consistent with best practices in the project for managing environment-based configuration, setting KONVEYOR_RULES to an empty string ("") or leaving it unset are treated as functionally equivalent states [3][4]. When the variable is either unset or set to an empty string, the system effectively ignores it or falls back to a default state, rather than attempting to process an invalid or empty configuration value [3][4]. This pattern is often implemented to ensure robust environment variable lookup, preventing errors that might otherwise occur if the application expected a non-empty string but received an empty one from a container orchestration platform or CI/CD runner [3][4]. In the specific case of Konveyor's agentic framework, this ensures that the controller can predictably resolve its ruleset configurations—often defined as OCI artifacts or directory paths—without encountering runtime failures due to misconfigured or blank environment variables [1][2].

"With KONVEYOR_RULES unset the harness injects every discovered skill"
💡 Result:
In Konveyor-related agentic ecosystems and similar AI harness frameworks, the behavior where the harness "injects every discovered skill" when a configuration variable like KONVEYOR_RULES is unset typically refers to a fallback mechanism for capability discovery and runtime loading [1][2]. When specific rule or skill scoping (such as KONVEYOR_RULES) is omitted, the harness does not have an explicit allow-list or filter for which capabilities to provide to the agent [1]. As a result, it defaults to a permissive state, performing a scan of the project or environment for all available skills and injecting them into the agent's context or tool registry [1][2]. This ensures that the agent has access to all potential functionality available in the environment, although it may lead to larger context usage [1][3]. This behavior is distinct from structured or progressive loading, where skills are only injected upon explicit selection or task-based need [2][3]. If users intend to limit the skills available to an agent to prevent potential issues (such as prompt injection or unnecessary context bloat), they should explicitly define the required skills or use the relevant environment variables to constrain the harness's discovery process [4][1].

"An empty value means there are none" KONVEYOR_RULES
💡 Result:
There is no official environment variable, configuration parameter, or documented component named KONVEYOR_RULES in the Konveyor platform [1][2][3]. Konveyor uses a rule-based engine (analyzer-lsp) for application modernization, where rules are defined in YAML files [1][3]. The Konveyor documentation and tools manage these rulesets through specific command-line arguments and file structures rather than an environment variable of that name [1][2][4]: 1. Input Handling: Rules are typically provided to the analyzer using the --rules flag, which accepts either a path to a YAML file or a directory containing a ruleset [1]. 2. Rule Structure: Rules are organized into rulesets, which consist of YAML files and a golden file (ruleset.yaml) [1]. 3. Ecosystem Tools: Tools such as Kantra (the Konveyor CLI) and rule-generation utilities use their own configuration methods, such as specifying paths via arguments (e.g., --rules /path/to/rulesets) or through project-specific repository structures [5][6][4]. If you encountered this term in a specific codebase or configuration, it is likely a custom variable name or a local convention specific to that implementation rather than a standard Konveyor platform setting [1][7].

While KONVEYOR_RULES is not explicitly defined as a specific configuration key in the provided documentation, the term relates to the broader Konveyor ecosystem: 1. Konveyor Rulesets: These are collections of YAML-based static analysis rules used by the konveyor/analyzer-lsp engine to assist with application modernization [1][2][3]. These rules are organized by technology and language within the konveyor/rulesets repository [1][4]. 2. Rule Management and Generation: Various tools like kantra, konveyor/ai-rule-gen, and konveyor-ecosystem/analyzer-rule-generator are used to manage, test, and generate these rules [5][6][7]. 3.

If you are looking for how to configure rules for the Konveyor analyzer, the standard approach involves passing a file or directory path using the --rules flag to the konveyor-analyzer CLI, rather than relying on a specific environment variable named KONVEYOR_RULES [2][13].

The SkillCard schema in config/crd/bases/konveyor.io_skillcards.yaml at Lines 55-103 defaults type to skill. Existing cards used as constraints will therefore become on-demand and stop loading unconditionally. Add an inventory and migration check before enabling native mode.

The konveyor/agentic-controller project maintains its architectural documentation within the docs/adr/ directory of its repository [1][2]. While a specific file named 0014-skill-loading-and-prompt-assembly.md is referenced in the project's ADR structure, it does not appear in public indexes as a standalone, widely accessible document compared to other ADRs like the OCI packaging requirement [3] or recent governance discussions [4]. In the context of the konveyor/agentic-controller, the architecture relies on the following established patterns for skills and prompt assembly: Skill Packaging and Resolution: Skills are defined as individual units or rules (often managed via SkillCard CRDs) that resolve to OCI artifacts [1][2]. These artifacts are mounted at a specific path, typically /opt/skills/{name}/, within the agent's runtime environment [1][5]. Agent Template Pattern: The controller uses a template-based approach where an Agent CRD declares available skills, container images, and prompts, while an AgentRun CRD provides the concrete values and instructions for execution [1][2]. General Documentation: For comprehensive details on the project's approach to skill resolution, orchestration, and the Agent/AgentRun contract, contributors are directed to the docs/adr/ directory in the official repository [1], or the project's enhancements repository which covers topics such as workspace persistence and skill layout assumptions [5].

This is an exceptionally well-written ADR. The problem statement is precise, the probe data is empirical, the alternatives are exhaustive, and the consequences are documented with unusual candor. The decision aligns with CONTEXT.md and addresses real defects (unreachable supporting files, type being a no-op, always-loaded context bloat). Five comments inline — refinements, not blockers.

The wire format for KONVEYOR_RULES isn't defined — comma-separated? JSON array? Space-separated? This is a controller-harness contract both sides independently implement. If #136 already implements the harness side, document the format it uses. Suggest: comma-separated list of SkillCard names. Unset or empty means no rules.

Savitha's test run on #136 showed a second risk beyond not-loading: even when the agent loaded a skill and read all its references, output contracts ("MUST write to .konveyor/spec.md") were not reliably followed. Native loading delivers content as tool-call context, which the model treats with less authority than prompt-injected content. Worth adding this to the rationale — it strengthens the "anything that must run is a rule" recommendation with empirical evidence, not just theoretical risk.

The ADR correctly identifies that 0001:106 is false but then says "this ADR does not supersede it" while leaving the false claim standing.

This is well-documented as a consequence but the trust model should be stated explicitly. Is the cloned repository within the trust boundary? For Konveyor migration, we're running agents against user-owned code — a repo could shadow a platform skill intentionally or accidentally. For type: rule this is safe (harness reads from mount). For type: skill, it's undetected. At minimum the harness should log when a skill name appears in both the clone and the mount.

Took all five, thanks. On the wire format, #136 doesn't actually implement the harness side, there's no rules handling in it at all, so there was nothing to document and I defined it: On the output contracts, I took the observation but left the explanation out. The run showing the plan stage load everything and still write to the wrong path is the useful part, and it does strengthen the rules recommendation. I don't think it establishes that tool-call context carries less authority than prompt-injected content though, so the ADR records what happened without claiming why. |
Records the decision to stop assembling skill content in the harness and let the agent runtime disclose skills progressively, while keeping always-loaded rules harness-assembled. Rules stay mounted under /opt/skills and are named to the harness in KONVEYOR_RULES, so a rule-typed skill is injected and still reachable by load_skill for its supporting files. Verified against block/goose v1.45.0, the version pinned in images/agent-base/Containerfile, and measured in agent-base itself: with ~/.agents/skills linked at /opt/skills, goose lists the mounted skill from the home root as uid 1001 with the mount read-only.

Define the KONVEYOR_RULES wire format and the ordering constraint it implies, record the konveyor#136 workflow run as evidence for making stage drivers rules, state the cloned repo as untrusted and require the harness to log skill-name collisions, supersede ADR 0001's runtime-discovery claim in the Status line, and drop the stale instruction to ADR 0010 now that konveyor#108 carries it.

All five comments addressed, two with pushback that improved on the original suggestions. Defining the unset-means-no-rules sequencing constraint explicitly, and recording Savitha's output-contract observation without claiming a mechanism for it, are both sharper than what I asked for. The ADR 0001 supersession is framed correctly as a factual correction, and the trust-boundary section now states the model explicitly with the shadow-logging mitigation. Solid work.

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.

Solid ADR — the reasoning holds up and the technical claims check out against what's actually shipped in harness/cmd/migration-harness/main.go and resolveSkillVolumes.
A few things worth keeping in mind as this moves forward, not blockers:
- HARNESS_SKILL_MODE=inject is decided in prose but isn't in the "What changes" checklist or in code yet — worth making sure it lands before native mode is something teams are depending on in production, given the two failure modes already seen in the #136 test run.
- The type: rule fix for the wrong-output-path failure (vs. the load_skill failure) reads as asserted rather than re-measured — might be worth a caveat in the text, or a follow-up run once there's bandwidth.
- Since type defaults to skill, a forgotten retype on a stage-critical SkillCard fails silently. A controller Warning condition down the line would be a cheap guardrail here.
Closes konveyor#135, follow-up to the konveyor#70 spike. goose has its own skills implementation and never sees the ones we mount, so the harness concatenating every `SKILL.md` into the prompt is doing work the runtime would do better. This says the harness stops assembling skill content and links `~/.agents/skills` at `/opt/skills` instead, so goose discovers them and `load_skill` resolves supporting files. `skills/javaee-to-quarkus` ships 12 files under `modules/` and `references/` that the agent can't reliably reach today, which is the concrete thing it fixes. The one thing that can't be native is `type: rule`. Nothing in goose forces a skill into context, so rules stay harness-injected. They keep their mount at `/opt/skills` and the controller names them in `KONVEYOR_RULES`, so a rule is both injected and still discoverable for its own `references/`. Unset means inject everything, which is what the harness does today, so an old controller with a new harness doesn't silently drop rules. Verified against goose v1.45.0, the version agent-base pins, and measured in the image: with the link in place `goose skills list` picks up the mounted skill as uid 1001 with the mount read-only. Transcript's in the ADR. Not verified is the `goose serve` path, the probe drives the CLI. The harness half is already implemented in konveyor#136. What's left is the rules path, the container-layout globs in `skills/execute`, `skills/verify` and `skills/plan`, and retyping any existing SkillCard written as a constraint, since `type` defaults to `skill`. Numbered 0014 because konveyor#108 has 0009-0011 and konveyor#106 has 0012-0013 open. Happy to renumber if either lands differently. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Added architectural documentation for native skill discovery and progressive skill loading. * Documented how ordinary skills and rule-based skills are handled, including an option to restore legacy behavior. * Added guidance on skill naming, shadowing, validation limitations, discovery mechanics, and rejected alternatives. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Fabian von Feilitzsch <fabian@fabianism.us> Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
## Summary Adds user-facing documentation and sample manifests so new contributors and testers can deploy the controller and configure agent workloads without reverse-engineering the codebase. ### What's included **Getting-started guide** (`docs/getting-started.md`): - Prerequisites (K8s 1.33+, Agent Sandbox) - Deploying the controller (`make deploy`) - Creating Gateways with credentials for each provider - Creating an Agent and triggering an AgentRun - Workflow pointers, local dev, e2e testing, troubleshooting **Sample CRs** (`config/samples/`): - `gateway_vertex_ai.yaml` — GCP Vertex AI with Claude - `gateway_openai.yaml` — OpenAI GPT-4o - `gateway_anthropic.yaml` — Anthropic direct API - `gateway_aws_bedrock.yaml` — AWS Bedrock - `agent_example.yaml` — Java migration agent referencing a gateway and skill - `agentrun_example.yaml` — Triggers the migration agent Sample CRs are self-contained reference examples with inline comments explaining prerequisites (e.g. secret creation commands). They are not added to the samples kustomization since they require user-specific credentials. **README update**: Added a "Getting started" section linking to the new guide. ### Context From team discussion: multiple people were blocked on testing because there was no documentation on how to configure things after deploying the controller. The `LLMProvider` CRD was renamed to `Gateway` and some team members were still on the old version without realizing. ### ADR compatibility Reviewed all open ADR PRs (#108, #106, #138) before writing. The guide stays at the CRD-level user interface and does not describe internal delivery mechanisms (params.json, skill loading, ACP transport) that are in flux. Nothing here contradicts pending decisions. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added sample configurations for Agents, AgentRuns, and AI gateways across Anthropic, AWS Bedrock, OpenAI, and Vertex AI. * Added a Java EE-to-Quarkus migration Agent example with repository and branch parameters. * **Documentation** * Added a comprehensive getting-started guide covering setup, deployment, provider configuration, workflows, testing, cleanup, and troubleshooting. * Added a README link to the getting-started guide. * **Bug Fixes** * Updated the AWS Bedrock example to use the Claude Sonnet 4.5 model identifier. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: David Zager <david.j.zager@gmail.com> Signed-off-by: Dylan Murray <dymurray@redhat.com> Co-authored-by: Dylan Murray <dymurray@redhat.com>
