docs(agents): add development principles to AGENTS.md and agent docs - #4859
The same mistakes kept coming back in reviews of agent-written changes. A failure was blamed on whatever changed just before it, with no mechanism behind the claim. Commands ran against the current kubectl context while the work moved between the management cluster and tenant clusters. Prose edits got invented failing tests, and behavior changes landed without any.
References and review feedback were the other source. Review corrections were stacked as new commits instead of rewriting the change. Closing keywords went into commits for partial fixes, while the PR itself did not link the issue. Feedback in review bodies and conversation comments was missed because only inline threads were read. A rerun of the fork E2E workflow was taken as proof that an unmerged edit to that workflow works.
I wrote these down as rules, so a review does not have to teach the same thing again. They go into AGENTS.md and docs/agents/, which agents and people both read, and the PR template now asks to link the issue a PR addresses.
This also fixes my earlier advice on negated Bats assertions: such an assertion can pass silently, but bats does fail it when it is the last command of the test.
Screenshots
Downstream repositories
The ccp package commit template and the community contributor guide restate parts of these rules. Both follow-ups are open issues, to be done once this lands.
No downstream repository is affected by this change
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The changes revise agent working and testing guidance, contribution and review procedures, and E2E workflow instructions. The PR template also adds guidance to link addressed issues.
Changes: Agent guidance
Layer / File(s)
Summary
Working and testing practices AGENTS.md, docs/agents/overview.md
Adds working principles and guidance for tests, Markdown formatting, Helm value validation and lookup, container images, and example data.
Commit and PR guidance docs/agents/contributing.md, .github/PULL_REQUEST_TEMPLATE.md
Updates migration and commit instructions, issue references, and PR-body content. The PR template asks contributors to link addressed issues.
Review feedback and retrieval docs/agents/contributing.md
Adds review-response instructions and expands the GraphQL query and pagination guidance for reviews, threads, and PR comments.
E2E cluster and workflow guidance AGENTS.md, docs/agents/e2e-testing.md
Updates readiness-check guidance, documents fork workflow behavior, and revises guidance on negated BATS assertions.
Issue 5245 concerns readiness-helper timeout and error handling. This PR documents the helper’s polling-budget behavior and manual invocation, but does not change or fix the helper.
Merge Risk: Low · up to 752d2
The documentation changes are mergeable with bounded follow-up: broaden historical-comment checks to every history replacement, identify and recheck the verified commit, and complete the tracked downstream commit-template update. No production behavior changes are introduced.

Explanation
The title "docs(agents): add development principles to AGENTS.md and agent docs" matches the main change. The PR adds Working Principles to AGENTS.md and updates the agent and contributor docs (contributing, e2e-testing, overview) plus the PR template. The title names the scope and the type of change. It does not mention the broader set of edits, such as the migration-script kubeconfig rules, the review-comment collection changes, or the issue-linking template change. That is expected for a short title.

- **A causal claim needs a mechanism.** A failure that appeared after a commit, a bump or a rerun was not thereby caused by it, and matching symptoms prove nothing either: unrelated faults often look identical from outside. Back a root cause with a log line, a reproducer, a bisect, or a ruled-out alternative; without one, name at least two hypotheses and what would tell them apart. Before tying a problem to a change, check whether it predates the change (an older run, a condition's `lastTransitionTime`, `git blame`). When the proof fails, closing the hypothesis as coincidence is a valid verdict, and a better one than carrying it on as a soft suspicion.
- **Verify, do not recall.** Versions, CLI flags, API fields and defaults drift faster than a model's training data. Check the upstream source, the documentation at the pinned version, or `--help` before writing code or advice that depends on them. When a problem is not solved after two attempts, stop and research it instead of trying a third variation.
- **Long flag names.** New and changed commands in docs, scripts, CI and PR text spell options out (`--namespace`, `--output`, `--filename`, `--message`), so that a reader does not need to know what `-f` means to this particular tool. An option with no long form is the only exception.
- **Name the cluster.** Every `kubectl` call an agent makes carries `--context`, because the current context can change between two commands. E2E suites, BATS files that talk to a cluster, and `make apply` run only against a cluster the human named for that purpose.
The reason will be displayed to describe this comment to others. Learn more.
Why --context on every kubectl call, read-only ones too? Helm and anything else that is not kubectl still use the current context, so this covers only part of the cases, and agent docs here have 18 kubectl lines without it. Was there a real case behind it? If not, I think it is enough to say that agent uses only the kubeconfig human gave it for the task.

myasnikovdaniil Management and tenant clusters have been confused during automated work. I kept explicit targets for reads too, and extended the rule to cluster-facing Helm commands and wrappers in 22e45c6. The operational examples now reject an unset context.
- **E2E tests:** Kyverno Chainsaw suites in `hack/e2e-chainsaw/` (one directory per app), run with `chainsaw test`. Cluster bootstrap (`hack/e2e-install-cozystack.bats`) and the OpenAPI checks (`hack/e2e-test-openapi.bats`) remain BATS. Conventions for writing and stabilising them — and the CI that runs them — live in [`e2e-testing.md`](./e2e-testing.md).
- **Go tests:** standard `go test`, with Ginkgo/Gomega for controllers.

Test-first reads as always required. Rule 3 forbids weakening or deleting a test, but a test that pins behaviour the change replaces has to be edited, and for a vendored chart bump or docs there is nothing to write red first. Please scope it to changes with testable behaviour and allow editing a test when the spec it pins changed.
The reason will be displayed to describe this comment to others. Learn more.
myasnikovdaniil I scoped the rule to changes with testable behavior. Docs-only edits and unmodified upstream updates need validation without an artificial red test. Tests may change when the contract changes, not just to make CI green. Updated in b69f2df.
A new first-party image is built from a `Containerfile`, which the package `Makefile` passes to `docker buildx build` with `--file`. Existing `Dockerfile`s and the files of vendored images stay as they are.
The reason will be displayed to describe this comment to others. Learn more.
Why enforce Containerfile for new images? We build with docker buildx build, so it needs explicit --file in every Makefile, and repo has 49 Dockerfiles against 2 Containerfiles. Podman and renovate accept both names, so I don't see what we get from it. Cost is there though, everything that matches image build files by name has to know both now, #4892 is one such case already.
The reason will be displayed to describe this comment to others. Learn more.
myasnikovdaniil I'm keeping neutral names for new first-party entities. New image definitions use Containerfile with an explicit --file; existing and vendored definitions keep their names. The principle is explicit in 22e45c6.

Nothing here says that a PR fixing an issue must link it. Closes: #N is only in commit trailers, and GitHub docs say keyword in commit message closes the issue on merge, but PR is not shown as linked to it. Please add Closes #N to the PR body rules, and a line for it to .github/PULL_REQUEST_TEMPLATE.md.

myasnikovdaniil I added the requirement to the rules and template. The change in 6514bb2 uses a closing keyword for a fully resolved issue and a normal link for partial work.
- A review reply answers the point raised in a few sentences. An essay-shaped reply reads as machine-written and draws exactly that question.
- Read a terse review literally: answer what was written, not an implied tone, and concede plainly when the reviewer is right.
- An `@mention` is a notification someone receives. Open a reply to a specific person with their handle; do not re-mention someone already in the thread in every message, do not mention the person you act for in their own PR, where every notification already reaches them, and do not `cc` bystanders.
- A nudge restates where the PR stands and asks one concrete question. It is never the word "ping".
The reason will be displayed to describe this comment to others. Learn more.
These lines look too narrow for agent rules (no "ping", no cc, reply length). What I think matters more and is not described now (examples that came to mind, not a full list):
severity levels for findings, so agent knows what blocks a merge and what is a nit
one naming for findings, same for humans, agents and CodeRabbit (it already writes Major, Minor, Nitpick)
whether CodeRabbit findings must be handled at all, and how
Fetching section also covers only unresolved threads, and CodeRabbit puts outside-diff findings in the review body, this PR has one.

myasnikovdaniil I shortened the etiquette rules. Review collection now covers submission bodies and conversation comments, including outside-diff findings from CodeRabbit, in 6514bb2. I'll take the severity taxonomy to a separate community proposal.

CodeRabbit (@coderabbitai) I updated the operational examples. The migration read requires an explicit context in 6514bb2. The readiness wait requires a context and timeout in e46d141.
@lexfrei I checked both examples. The migration read requires KUBE_CONTEXT. The readiness wait requires KUBE_CONTEXT and HR_READY_TIMEOUT, and the guidance calls for a re-list against the same context.
CodeRabbit (@coderabbitai) I clarified the stub-test rule. The red test belongs to development; the intended behavior must be implemented and the test must pass before merge. Updated in 3edf8df.

commit comments alongside the existing sources before declaring feedback
addressed.

qualified references for issues in other repositories, such as
owner/repository#N, including when using a closing keyword in the PR body or
commit trailer. Preserve the existing guidance for issues in the current

work.
- Line 169: Update the PR issue-linking guidance in the contributing
documentation to clarify that for PRs targeting a release branch, `Closes #N`
will not create a linked-issue entry or close the issue on merge. State that a
maintainer with write access must link the issue manually and close it
separately when appropriate, while preserving the existing guidance for other
PRs.
Review comments at @docs/agents/e2e-testing.md:
- Line 97: Update the readiness guidance around the helper’s timeout diagnostics
to state that unready details come from the last successful poll and may be
stale if later list operations fail; retain the warning that the final
diagnostic list can also fail and do not suggest masking the helper’s exit
status.
- Line 93: Update cozy_wait_all_helmreleases_ready to check HR_READY_TIMEOUT
before accepting the stable Ready set, so a second Ready list returned after the
deadline cannot report success. Add a slow-success regression test that verifies
this case fails.
- Line 93: Update cozy_wait_all_helmreleases_ready to check the exit status of
both the stalled and not-ready jq queries; return failure if either query fails,
rather than treating the quiet interval as confirmation that all releases are
ready.
- Line 93: Bound the entire cozy_wait_all_helmreleases_ready invocation by a
wall-clock limit derived from HR_READY_TIMEOUT, so a blocked credential plugin
cannot keep the manual readiness check running indefinitely. Ensure timeout
expiration and any failure from the readiness check both propagate as a nonzero
exit status.
- Line 93: Update the guidance around cozy_wait_all_helmreleases_ready so
HR_READY_TIMEOUT values with leading zeroes are handled as decimal before
deadline arithmetic, or clearly document that callers must provide the timeout
without leading zeroes.
- Line 91: Update the kubectl wrapper and readiness check example so they use
the supplied kubeconfig when one is available, passing that kubeconfig through
the wrapper alongside the selected context; preserve the existing behavior when
no supplied kubeconfig is available.
Review comments at @docs/agents/overview.md:
- Line 123: Update the BATS failure guidance to explain that a `!`-negated
assertion may pass when it should fail, that `bats` catches it when it is last
in the test body, and that `hack/cozytest.sh` does not. Keep the warning not to
use this form and preserve the reference to §11 of `e2e-testing.md`.
- Line 139: Update the guidance for validating nested values to require guarding
or normalizing each parent map before accessing or validating its children, so
missing or null parents produce the intended validation message instead of a
nil-pointer error.

Fail the readiness check when a jq query fails.
If the not-ready query fails before producing output, the helper can report all releases Ready after the quiet interval. Check the exit status of both the stalled and not-ready queries in hack/e2e-wait-helmreleases.sh and return a failure when either query fails.

Update cozy_wait_all_helmreleases_ready to check the exit status of both the
stalled and not-ready jq queries; return failure if either query fails, rather
than treating the quiet interval as confirmation that all releases are ready.

Bound the entire cozy_wait_all_helmreleases_ready invocation by a wall-clock
limit derived from HR_READY_TIMEOUT, so a blocked credential plugin cannot keep
the manual readiness check running indefinitely. Ensure timeout expiration and
any failure from the readiness check both propagate as a nonzero exit status.

Update the guidance around cozy_wait_all_helmreleases_ready so HR_READY_TIMEOUT
values with leading zeroes are handled as decimal before deadline arithmetic, or
clearly document that callers must provide the timeout without leading zeroes.

@lexfrei Thanks for reproducing this and documenting the limits. The guidance now states that HR_READY_TIMEOUT is a polling budget and must not have leading zeroes.
#5245 tracks the late Ready result, jq failures, and the lack of a process-level timeout. The helper fix remains open.
For best results, initiate chat on the files or code changes.

Included review availability: This review used your included allowance. Your plan provides up to 8 included reviews per hour; 7 remain after this review.
A commit that fixes a defect introduced by an earlier commit carries a kernel-style `Fixes:` trailer with at least 12 characters of the hash and the full subject, on one unbroken line, which `git log --max-count=1 --abbrev=12 --format='Fixes: %h ("%s")' <sha>` prints. `Fixes: #N` is not used, so that the `Fixes:` trailer always points at a commit.
Use `Closes: #N` only when the change fully resolves the issue. For partial work, use a non-closing reference such as `Refs: #N`; a closing commit trailer can close the issue when it reaches the default branch even if the PR body uses a non-closing link. For an issue in another repository, qualify the reference as `owner/repository#N`, including in a closing trailer (`Closes: owner/repository#N`). Reference trailers go after the body and before `Assisted-by:` and `Signed-off-by:`.
Align the package-bump commit template with the new convention.
When a package bump fixes a defect introduced by an earlier commit, the downstream template can produce a commit without the required Fixes: trailer. Update the skill to include the introducing commit reference in that case, and link the downstream follow-up.

The release-branch guidance calls for a non-closing reference and manual issue linking and closure when appropriate.
The standalone readiness example uses set -e and requires a positive decimal timeout without leading zeroes. It also states that the timeout is a polling budget, not a strict wall-clock limit.
#5245 tracks the helper’s parser handling and deadline limitations.

Requesting changes. The lookup hunk reverts what we agreed in #5168, and two new principles in AGENTS.md can't be applied or checked by agent ("first-party entities", "30 seconds"). The e2e helper notes are off topic for this PR. Issue links and the template line look right, keep them.
- **Verify, do not recall.** Versions, CLI flags, API fields and defaults drift faster than a model's training data. Check the upstream source, the documentation at the pinned version, or `--help` before writing code or advice that depends on them. When a problem is not solved after two attempts, stop and research it instead of trying a third variation.
- **Long flag names.** New and changed commands in docs, scripts, CI and PR text spell options out (`--namespace`, `--output`, `--filename`, `--message`), so that a reader does not need to know what `-f` means to this particular tool. An option with no long form is the only exception.
- **Name the cluster.** Management and tenant clusters are different targets. Every `kubectl` call, including reads, carries `--context`; cluster-facing Helm commands carry `--kube-context`. Use the human-approved target and the task's kubeconfig where one was supplied, not the ambient current context. Before running wrappers or cluster-facing tests, verify that they propagate the chosen target. Tests that need no cluster must not inherit live cluster credentials.
- **Vendor-neutral names.** Use vendor-neutral names for new first-party entities when an equivalent neutral name is supported. Keep existing names and vendored content unchanged. Refer to external products, commands and APIs by their actual names.
The reason will be displayed to describe this comment to others. Learn more.
Agent can't apply this, "first-party entities" and "equivalent neutral name" are not defined, and the file is loaded on every task. Containerfile itself is fine for me, the instruction is the problem. Either say exactly what it covers (image build files?) and move it to overview.md, or drop it.

myasnikovdaniil I removed the general naming rule. The image-build section now covers only new images built from source maintained in this repository; existing and vendored filenames stay unchanged. Updated in 1e7ba63.

- **Respect the reader's time.** Aim for prose a reader can read and understand in 30 seconds. Lead with the answer or decision; prefer direct wording over formalities, filler and repeated conclusions. Put necessary detail after a short summary or in a linked document, rather than dropping facts to fit a word limit. See [Slop Grenade](https://noslopgrenade.com/).

Same here, "30 seconds" can't be measured by agent, so it is not a rule. The link goes to a personal site and agents read this file on every task. Please drop the number and the link, "lead with the answer, no filler" is enough.
- For nested values, validate or normalize each parent map before reading its children; checking only the leaf cannot prevent a nil-pointer error from a missing or null parent.
**No `lookup` that copies another object into the render.** A `lookup` reads cluster state at render time, and nothing re-renders the HelmRelease when that state changes, so whatever it copied into the output (a bucket name, an endpoint, a CA, a list of StorageClasses) stays stale until something unrelated upgrades the release. Lookups of this kind already in the charts have caused failures, and several have since been moved to values, so they are not precedent: do not add one of this kind unless a maintainer has authorized that specific one.
**`lookup` is prohibited by default.** Do not add a call or expand an existing one unless it is essential to the required behavior and a maintainer approves that specific use. It introduces a live-state input that offline rendering cannot reproduce; a change to the object it reads does not itself trigger a HelmRelease upgrade. Existing calls are not precedent, and convenience is not sufficient justification.

This reverts the rule we agreed in #5168 (merged Oct 30). Existence checks, keeping a generated Secret and fail guards are banned again, and #5168 narrowed the rule because banning them pushed agents toward nothing better. Please drop this hunk and keep the text from main. If there is a failure the current wording doesn't cover, open an issue with it first.

This goes the wrong way. PR count grows every month and review has to scale with it, one-field fix in an app spec should not get the same process as a migration or an API change. This section adds steps to every review (four sources, pagination, head/base SHA pair, comments on replaced commits). Please cut it back to the four sources and "verify each finding against current code". Kinds of PRs and review depth for each is what I think we need, it doesn't have to be in this PR.
- Dump the full Ready-condition message per non-Ready HR so the real error is in the test output. See `hack/e2e-install-cozystack.bats`.
Use `cozy_wait_all_helmreleases_ready` from `hack/e2e-wait-helmreleases.sh`, as `hack/e2e-install-cozystack.bats` does. Keep the helper's minimum release count, observed-generation checks, stable all-Ready set and fail-fast behavior on `Stalled=True`. A single wait and re-list does not preserve those checks.
For a manual readiness check from the repository root, set `KUBE_CONTEXT` to the human-approved sandbox context and `HR_READY_TIMEOUT` to a positive base-10 integer number of seconds without leading zeroes, using [Sizing an HR-Ready budget](#sizing-an-hr-ready-budget). If the task supplies a kubeconfig file, set `KUBE_CONFIG` to its path; otherwise leave it unset to use kubectl's normal configuration loading. The subshell binds the helper's kubectl calls to that target without changing the caller's shell or the global current context:

Please drop the manual subshell and the notes about helper limits. They describe bugs that #5245 tracks, so they go stale when it is fixed, and this PR is not about the helper.

Approving, my previous points are fixed, notes below are optional and can go in follow-up PR.
docs/agents/contributing.md:187 asks for one line on how change was tested, but line 67 still says body explains why "and only that". Line 67 should allow test line, now they contradict each other.
GraphQL query for unresolved threads was removed together with the rest of that section (docs/agents/contributing.md:326). REST has no resolution status, so agent can't tell which inline threads are unresolved. My ask was wider than I meant here, short query from main with body instead of bodyText is enough.

What this PR does
The same mistakes kept coming back in reviews of agent-written changes. A failure was blamed on whatever changed just before it, with no mechanism behind the claim. Commands ran against the current kubectl context while the work moved between the management cluster and tenant clusters. Prose edits got invented failing tests, and behavior changes landed without any.
References and review feedback were the other source. Review corrections were stacked as new commits instead of rewriting the change. Closing keywords went into commits for partial fixes, while the PR itself did not link the issue. Feedback in review bodies and conversation comments was missed because only inline threads were read. A rerun of the fork E2E workflow was taken as proof that an unmerged edit to that workflow works.
I wrote these down as rules, so a review does not have to teach the same thing again. They go into
AGENTS.mdanddocs/agents/, which agents and people both read, and the PR template now asks to link the issue a PR addresses.This also fixes my earlier advice on negated Bats assertions: such an assertion can pass silently, but
batsdoes fail it when it is the last command of the test.Screenshots
Downstream repositories
The ccp package commit template and the community contributor guide restate parts of these rules. Both follow-ups are open issues, to be done once this lands.
