Description

Restructures AGENTS.md into a short routing core that links to the documents which already
own each subject, and adds the three things it was missing: what an agent may do, that
secrets must never be committed, and worked examples of preferred versus deprecated patterns.

Part of the OSS Health Scorecard work tracked in #513.

What

  • Sections whose content already lives elsewhere now link there instead of duplicating it:
    build and test detail to DEVELOPMENT.md, contribution mechanics to CONTRIBUTING.md,
    component descriptions to docs/architecture.md, label detail to
    docs/reference/node-labels.md.
  • A new section stating which directories are in scope for an agent's own initiative and which
    surfaces need maintainer discussion first, using the load-bearing surfaces this repo already
    names.
  • An explicit prohibition on committing credentials, secrets, API keys, tokens and environment
    variable values.
  • Preferred and deprecated Go examples drawn from the real provider interface, including
    returning *httperr.Error rather than plain error at the provider boundary.

Four stale facts in the repository map were corrected against the tree: pkg/providers/
gained dsx and nscale, pkg/engines/ gained graph, internal/ gained kwok.

What did not move, and why

Six headings stayed verbatim because CONTRIBUTING.md deep-links into them, and
CONTRIBUTING.md:112 names AGENTS.md as the source of truth for the provider checklist and
the anti-patterns table. Moving those would have broken inbound links and inverted stated
ownership.

.claude/CLAUDE.md carries the byte-identical body, per this repo's own rule that the two
stay in sync.

Verification

No information was lost in the restructure: every removed subject was checked to be present
in the document it now points at.

Measured effect

Agent Readiness 1.70/4 to 3.00/4, +1.30 points.

Documentation only.

Part of #513.

Checklist

  • I am familiar with the Contributing Guidelines.
  • New or existing tests cover these changes.
  • The documentation is up to date with these changes.
  • All commits are signed off per DCO (git commit -s).

AGENTS.md carried setup, build, test, and pull-request mechanics that
DEVELOPMENT.md and CONTRIBUTING.md already own, and it linked to neither.
Readers and coding agents had two copies of the same rules to keep in step,
and the copies had already drifted.

Route those sections to the documents that own them, and add the three
things the file was missing: an explicit statement of which directories an
agent may change on its own and which surfaces need maintainer agreement
first, an explicit prohibition on committing credentials, secrets, API keys,
tokens, and environment variable values, and preferred-versus-deprecated Go
examples for the provider error type and for building the fabric path.

Also correct the repository map against the tree: pkg/providers/ gained dsx
and nscale, pkg/engines/ gained graph, and internal/ gained kwok, so the
engine count is five rather than four.

The headings CONTRIBUTING.md deep-links into are preserved, and
.claude/CLAUDE.md is updated with the identical body in the same commit, as
this repo's own rule requires.

90-90: Permit the two guide files in provider-task scope.

Line 90 excludes AGENTS.md and .claude/CLAUDE.md, but later rules require both files when a new provider changes the documented repository surface. Add both paths or define an explicit exception. This repeats the unresolved finding from the previous review.

Greptile Summary

This documentation-only PR restructures the agent guidance into a concise routing core while preserving repository-specific invariants and contribution checklists.

  • Routes build, contribution, architecture, and label details to their owning documents.
  • Defines autonomous agent scope and maintainer-controlled surfaces.
  • Adds explicit secret-handling guidance and preferred/deprecated provider examples.
  • Updates the repository map and keeps AGENTS.md and .claude/CLAUDE.md aligned with directory-correct links.

Confidence Score: 5/5

The PR appears safe to merge; the changes since the previous review fully address the provider scope, conditional testing, and nested-document link issues.

No actionable new issue remains. The provider scope now includes all checklist-required documentation, tests are required only for behavioral changes, and the Markdown links in .claude/CLAUDE.md use the correct parent-relative paths.

Important Files Changed

Filename Overview
AGENTS.md Replaces duplicated operational guidance with a root-relative routing core, scope boundaries, security guidance, and provider examples.
.claude/CLAUDE.md Mirrors the routing guidance while using parent-relative Markdown links appropriate to its .claude/ location.

Keep the agent-scope allowlist consistent with later documentation requirements. The allowlist omits the two agent guides, although later rules require both files to change for new invariants and repository-map changes.

🌐 Web query:

official gh pr create --template option manual

💡 Result:

The command gh pr create provides a --template (or -T) flag, which allows you to specify a local file to use as the starting body text for your pull request [1][2][3]. Usage: gh pr create --template Key details: 1. File Input: The --template flag expects a path to a local file (e.g., "pull_request_template.md") [1][4][2]. 2. Mutual Exclusion: You cannot use the --template flag in combination with the --body or --body-file flags [3]. 3. Purpose: This is particularly useful for automating the creation of pull requests that require a standardized structure or checklist defined in a template file [1][2]. Example: $ gh pr create --template "my_template.md"

🌐 Web query:

site:cli.github.com/manual/gh_pr_create "If the --template flag is not set" pull request template

💡 Result:

When using the GitHub CLI (gh pr create) to create a pull request, the command does not automatically detect or apply repository-based pull request templates if the --template flag is not explicitly set [1]. The --template flag, or its shorthand -T, allows you to specify a local file to use as the starting body text for the pull request [1]. If this flag is omitted, the command will not pull in the.github/pull_request_template.md or similar standard template files automatically [1]. To use a template file, you must provide it explicitly via the command: gh pr create --template "path/to/your/template.md" [1]

Citations:


Update the GitHub CLI template instruction. GitHub UI auto-populates the template, but gh pr create does not apply it automatically. Document gh pr create --template .github/PULL_REQUEST_TEMPLATE.md, or require manual checklist copying, in both files.

…paths

Addresses the Greptile review on NVIDIA#516.

The permitted-scope row for a provider named only pkg/providers/<name>/ and the
one-line registry entry, while the provider checklist in the same file also
requires docs/providers/<name>.md and the docs/overview.md provider list. A new
provider page additionally needs a docs/index.yml entry, which the check in
.github/workflows/fern-docs-ci.yml fails without. An agent obeying the row alone
would file an incomplete contribution that CI rejects, so the row now names
those docs.

The blanket "ships with tests" also caught documentation and release-note
changes, which the same table permits and which cannot carry a meaningful test.
It now reads "ships with tests when it changes behavior", matching the pre-push
checklist, which asks for coverage of new or changed public behavior.

Relative links in .claude/CLAUDE.md resolved from .claude/, not from the
repository root: [DEVELOPMENT.md](DEVELOPMENT.md) pointed at
.claude/DEVELOPMENT.md, which does not exist. All eight links in that file now
carry a ../ prefix. The review named the four in the routing table; the other
four are in prose, in the architecture, coding-style, node-labels, and
pull-request sections.

That last fix makes the two files diverge on those eight lines, deliberately.
AGENTS.md sits at the repository root and its links are already correct, so the
two bodies can no longer be byte-identical. The sync rule is about content, not
byte equality, and a document full of broken links is not in sync with anything,
it is broken. Both marker comments now record the divergence and say not to
restore it.
