# Renovate Triage > Reads each open Renovate dependency-bump PR's changelog, release notes, and CI status, computes a Risk verdict — safe, needs-review, or blocked — from a fixed hard-stop rule list, and posts (or updates) one PR comment stating the verdict and reason; blocked PRs also get an Agent brief naming call sites and changelog sections for follow-up. Resolves each changed file's datasource (npm, Docker, PyPI, Ansible Galaxy) from the repo's own renovate.json rather than guessing from filenames. For a minor or major bump it also reports relevant Opportunities in a separate, verdict-independent section (skip with `--no-opportunities`); for every bump it also scans gathered changelogs for a Security advisory — a CVE, GHSA ID, or urgency language — reported the same way, never changing the verdict. Use when the user types /renovate-triage with no argument to scan every open Renovate PR in the current repo, with a PR number or URL to check one, or asks to triage, review, or assess Renovate PR risk. - Skill: `bgutschke/renovate-triage` (Agent Skill, multi-file: 26 files) - Install (CLI): `npx skillmds@latest add bgutschke/renovate-triage` - Raw SKILL.md: https://api.skillmd.com/api/skills/bgutschke/renovate-triage/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: DevOps & Infra - Author: bgutschke (https://skillmd.com/u/bgutschke) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/bgutschke/renovate-triage --- # renovate-triage **Risk verdict**: A Renovate PR's classification into one of three tiers — `safe`, `needs-review`, or `blocked` — computed by a fixed hard-stop rule list (an explicit breaking-change callout, a failing CI check, or a major bump with no changelog found anywhere, each alone forcing `blocked`) with a bump-size baseline underneath, rather than a weighted score. Blast radius (how widely the dependency is used in the consuming codebase) and CI-pending status can each escalate the baseline by one tier; dev-only vs. production placement is reported as context but never changes the verdict — both are escalated identically. **Agent brief**: A `blocked`-verdict's handoff content, written into the same PR comment as the risk verdict rather than a separate artifact. Addressed to an agent continuing the investigation, not a human skimming for discretion — concrete starting points: which call sites to inspect, which changelog or migration-guide sections to read. **Datasource**: Renovate's own name for a dependency's versioning source and lookup mechanism — `npm`, `docker`, `pypi`, `ansible-galaxy`, and others. A built-in manager (e.g. npm) has a fixed default datasource; a `customManagers` entry declares its own via `datasourceTemplate`. This skill resolves a changed file's datasource by reading the target repo's own `renovate.json`, never by guessing from the file's name or extension — a custom regex manager can point any file at any datasource. **Datasource adapter**: A declarative bundle — where to look for a changelog or release notes, and how to search the codebase for call sites — that evidence-gathering dispatches to once a file's datasource is resolved. One adapter per datasource; a resolved datasource with no adapter built is skipped and named, never given generic best-effort evidence gathering. For `docker`, one adapter run can consult two repositories — a packaging repository resolved from registry metadata, and an upstream repository found by scanning that packaging repository for an embedded GitHub URL — never guessed at from the image name. **Opportunity**: A relevant capability change found while scanning a minor or major bump's full release range (every version between old and new, not just the latest) — either a newly-added capability, or an existing capability the dependency now marks deprecated — cross-referenced against the dependency's actual call sites in the consuming codebase and reported only when relevant usage is found there. Reported per dependency, in its own comment section, alongside but never merged into the Risk verdict — it never escalates, de-escalates, or otherwise changes the verdict, regardless of tier or placement. **Security advisory**: An explicit security disclosure — an explicit CVE identifier, a GitHub Security Advisory ID, a "Security" heading, or explicit urgency/vulnerability language — found while scanning any changelog text this skill already gathered, for any datasource, regardless of bump size. Reported per dependency, in its own comment section, alongside but never merged into the Risk verdict — it never escalates, de-escalates, or otherwise changes the verdict. Unlike Opportunity, both its widened fetch and its reporting are unconditional: they run for every bump size and are never skipped by `--no-opportunities`, and a finding is never cross-referenced against this codebase's call sites — a security disclosure is reported regardless of whether a matching call site is found. The skill computes a Risk verdict for every open Renovate PR, or the single PR given as an argument, reports in-session, and maintains exactly one idempotent comment per PR, updated in place on later runs rather than duplicated. It never approves, merges, or labels a PR — every merge decision stays the maintainer's. By default it also scans every minor or major bump for Opportunities, reported in their own section separate from the verdict; pass `--no-opportunities` to skip that pass for a single run. Independent of bump size and of that flag, it also scans every dependency's gathered changelog text for a Security advisory, reported in its own section and never affecting the verdict. ## Dependencies Requires an authenticated `gh` CLI — every step shells out to it (`gh pr list`, `gh pr view`, `gh pr checks`, `gh api`, `gh pr comment`). Also requires `npm` and `node` — `npm` to resolve an npm dependency's repository URL (`npm view repository.url`, used only by the npm adapter), and `node` to run this skill's bundled resolution, extraction, detection, verdict, and validation scripts (`${CLAUDE_SKILL_DIR}/scripts/`). The docker, pypi, and ansible-galaxy adapters query their own registries over HTTP via `curl` — ambient on any machine capable of running Claude Code, like `git`, so it isn't listed as a precondition the way `npm` and `node` are. ## When to use - The user types `/renovate-triage` with no argument — every open Renovate PR in the currently checked-out repo gets a verdict in one pass. - The user types `/renovate-triage ` — re-check or spot-check exactly one PR without waiting for a full scan. - The user asks to triage, review, or assess the risk of Renovate dependency-bump PRs. ## When not to use - A PR whose resolved datasource (step 6) has no adapter built — anything beyond npm/docker/pypi/ansible-galaxy. This skill's evidence-gathering is designed around those four specifically; running it against an unhandled datasource would produce a verdict built on evidence it never actually gathered. A full-repo scan reports these PRs as skipped rather than silently omitting them — see step 9. - A PR whose changed files span more than one resolved datasource, or include a file whose datasource can't be resolved locally (`unknown` — including one reachable only through an `extends` preset this skill never fetches). Reported as skipped, not triaged on a partial assumption about what the PR touches — see step 8. - A repo whose Renovate config isn't found or isn't plain JSON (`renovate.json5` and JS-based configs aren't parsed) — reported as "detection unavailable," not silently skipped. See step 7. - Any repo other than the one currently checked out. There is no `--repo` flag and no cross-repo scanning. - Wanting the skill to approve, merge, or label a PR based on its verdict — it never does any of those, regardless of tier. - Wanting migration-guide research on every PR. A migration or upgrade guide is consulted only as a targeted follow-up when a `blocked` verdict's Agent brief needs more detail than the changelog alone gives — never a broad web search, and never for a `safe` or `needs-review` verdict. ## Resolving what to check Before either case below, strip `--no-opportunities` out of the raw arguments if present — a boolean switch, never combined with a value, that can appear with or without a PR number or URL. When present, this entire run skips step 16's Opportunity scan for every PR it checks; nothing else in this section changes — the Security advisory scan (step 15) is never gated by this flag. 1. **An explicit target was given** (PR number or URL): resolve it directly with `gh pr view --json number,title,url,body,headRefName,author,files`. This is always a single-PR check, regardless of who authored it or what datasource it touches — an explicit target names a PR that must already exist, and the datasource-resolution check below still applies to it. 2. **No target was given** (only `--no-opportunities`, or no arguments at all): list every open PR in the current repo — `gh pr list --state open --json number,title,url,body,headRefName,author,files` — and keep only the Renovate-authored ones: `author.login` equal to `renovate[bot]` or `app/renovate`. 3. **Zero PRs survive step 2**: report "no open Renovate PRs found" and stop — a clear confirmation the scan actually ran, not silence or an error. ## Orchestrating the scan 4. **No target was given** (step 2 produced one or more PRs): dispatch one sub-agent per PR via the Agent tool, run in parallel, each executing the complete per-PR flow below (datasource resolution through comment posting) independently for its own PR. PRs are already self-contained triage units — own rollup, own comment, own idempotency marker — so no cross-PR coordination is needed; each sub-agent reports its result back for step 23's summary. Adapters are never split out to their own sub-agent at dependency/datasource granularity — splitting evidence-gathering across a further sub-agent boundary would only add coordination overhead around an otherwise PR-scoped, deterministic flow. 5. **An explicit target was given** (step 1): run the flow inline in the current session, no sub-agent spawned — a quick spot-check shouldn't pay the parallel- orchestration overhead a full scan needs. ## Resolving each file's datasource Runs once per PR, before any evidence gathering, using the PR's `files` list from steps 1–2: 6. Read the target repo's Renovate config — its root `renovate.json`, or `.github/renovate.json` if the former doesn't exist — and run `node ${CLAUDE_SKILL_DIR}/scripts/resolve-datasource-cli.js --file [--file ...]` for every file the PR changed. **Execute this script directly — it deterministically matches each file against the config's `customManagers[]` entries (`managerFilePatterns` regexes paired with a `datasourceTemplate`) and a small table of built-in managers' default file patterns (npm's four filenames are one entry in this table now, not the sole recognized case), never re-derived by hand.** `extends` preset chains are never fetched or resolved — only the config file's own local content is read. It prints `{ status, datasources }` JSON: `status` is `resolved` or `detection-unavailable`; `datasources` maps each file to its resolved datasource string, or `"unknown"` when the file matches neither a built-in pattern nor a `customManagers[]` entry — the same result a datasource reachable only through an unresolved `extends` preset gets, since that case is locally indistinguishable from "not managed at all." 7. `status: "detection-unavailable"` (no `renovate.json` found at either location, or it failed to parse as JSON): report the PR as "detection unavailable" in place of a verdict (explicit single-PR target) or under a dedicated "detection unavailable" heading (full scan), and stop for that PR — a config problem surfaces instead of the PR silently disappearing from the scan. 8. Any file resolving to `"unknown"`, or a PR whose files resolve to more than one distinct datasource, marks the PR out of scope: Renovate doesn't normally group across datasources, so a mix (or an unresolved file) is evidence of an unusual PR this skill isn't designed to read correctly, not a partial PR to triage anyway. Report it under a "skipped — mixed or unresolved datasource" heading, naming each file's resolved datasource. 9. A PR whose single resolved datasource has no adapter built — anything beyond npm/docker/pypi/ansible-galaxy — is reported under a "skipped — no adapter for ``" heading, never given generic best-effort evidence gathering. A PR resolved to npm, docker, pypi, or ansible-galaxy proceeds to evidence-gathering below, using that datasource's adapter. ## Gathering evidence, per dependency Steps 10–14 run once per dependency changed in the PR — for a PR Renovate grouped into several dependencies, once per dependency in the group (see step 18 for how the per-dependency results roll up). Steps 11 and 14 are the two facets a datasource's adapter fills in (its changelog source, and its call-site search); steps 10, 12, and 13 are identical regardless of datasource. 10. Read the old and new version for this dependency from the PR's title or body (both fixed Renovate output formats naming the dependency and its version range, regardless of datasource), then classify the bump size immediately: `node -e "console.log(require('${CLAUDE_SKILL_DIR}/scripts/classify-bump-size').classifyBumpSize(process.argv[1], process.argv[2]))" `. **Execute this directly — it calls the exact same `classifyBumpSize` function step 17's `compute-verdict-cli.js` runs internally for the verdict, just earlier, so step 11 below knows whether to widen its changelog range; the bump size must never be hand-classified from the version strings.** 11. Look for a changelog or release notes, per the PR's resolved datasource: - **npm**: in this fixed order, stopping at the first hit — (a) the dependency's GitHub Releases, via `gh api repos///releases` once the dependency's repository URL is resolved from its npm registry metadata (`npm view repository.url`); (b) the dependency's own `CHANGELOG.md` at its new release tag, read from the same repository. - **docker**: a packaging repository from registry-published metadata only, never guessed from the image name (`pihole/pihole`'s real source is `pi-hole/docker-pi-hole`, not a same-named repo), tried in this order, stopping at the first hit: 1. The image manifest's own OCI config labels — fetched from the registry API directly, regardless of which registry hosts the image: an anonymous bearer token (`curl -s "https://auth.docker.io/token?service=registry.docker.io&scope=repository:/:pull"`), the manifest list for the target tag, the platform-specific manifest it points to, and finally that manifest's config blob, whose JSON body carries a `config.Labels` object. Write that `Labels` object to a file and run `node ${CLAUDE_SKILL_DIR}/scripts/extract-oci-source-label-cli.js --labels-file `. **Execute this script directly — it deterministically checks `org.opencontainers.image.source`, then `.url`, and parses an `owner/repo` pair out of a `github.com` URL, never guessed by hand from either label's raw text.** A `found` result names the packaging repository. A `none` result (neither label present, or the present label points at a non-`github.com` host) falls through to the next tier. 2. The existing registry field, kept as a cheap secondary check since it's occasionally still populated even when OCI labels are absent — a GHCR image's linked repository (`gh api orgs//packages/container/`, its `repository` field), or a Docker Hub image's `source_url` field (`curl -s https://hub.docker.com/v2/repositories///`) — the latter a relic of Docker Hub's old "automated builds" linking feature, empty for ordinary Docker Hub images in practice, not just edge cases. Once a packaging repository is found via either tier above, run the same GitHub-Releases-then-`CHANGELOG.md` order as npm's (a)/(b) against it. Always also look for a second, upstream repository, supplementing rather than replacing the packaging-repository lookup above: fetch the packaging repository's Dockerfile and version-pin files at the target tag — the same files this PR's changed-file list already resolved to the `docker` datasource in step 6 — via `gh api repos///contents/?ref=`, then run `node ${CLAUDE_SKILL_DIR}/scripts/extract-upstream-repo-cli.js --packaging-repo / --file [--file ...]` against their fetched content. **Execute this script directly — it deterministically scans for an embedded GitHub release/tag/tarball URL naming a different repository than the packaging one, never guessed by hand from the image or file name.** A `found` result names exactly one upstream repository — run the identical GitHub-Releases-then- `CHANGELOG.md` lookup there too. A `none` or `ambiguous` result (zero candidates, or more than one with no way to tell which is authoritative) means the adapter never guesses — it proceeds packaging-repository-only, using only what the packaging-tier lookup above already found. - **pypi**: the package's declared source from PyPI's JSON API (`curl -s https://pypi.org/pypi//json`) — a `Source`, `Repository`, or `Changelog` entry (case-insensitive key match) in `info.project_urls`, or `info.home_page` only when it itself points at a GitHub or GitLab repository. Never a guess from the package name. Once found, the same GitHub-Releases-then-`CHANGELOG.md` order. - **ansible-galaxy**: the collection's declared `repository` field from the Galaxy API v3 collection metadata (`curl -s https://galaxy.ansible.com/api/v3/plugin/ansible/content/published/collections/index///`). Never a guess from the namespace or collection name. Once found, the same GitHub-Releases-then-`CHANGELOG.md` order. **For every datasource, as a final tier**, tried only after every registry-metadata lookup above for that datasource has come back empty (for docker: both the packaging-repo tier and, when a candidate was found, the upstream-repo tier): check Renovate's own PR-body "Release Notes" section for this dependency, using the body text steps 1–2 already fetched (`gh pr view --json body`) — no extra fetch. Write that body to a file and run `node ${CLAUDE_SKILL_DIR}/scripts/extract-release-notes-from-pr-body-cli.js --body-file --dependency `. **Execute this script directly — it deterministically locates this dependency's own Release Notes section (never another dependency's, on a grouped PR) and classifies it, never re-derived by hand.** A `found` result's text satisfies the "changelog found" check below and feeds the breaking-change-callout scan (step 12) exactly like any other tier's text — but never the Security advisory scan (step 15) or the Opportunity scan (step 16) — see the "combined text" paragraph below. A `compare-link-only` result (the section's only content is a bare Compare Source link, no itemized entries) or an `absent` result (no section for this dependency at all) contributes nothing — the adapter's own registry-metadata tiers' emptiness still stands. "No changelog or release notes found anywhere" (relevant to the major-bump hard-stop below) means every tier for that datasource — including this PR-body fallback — came back empty at every stage; for docker specifically, this means the packaging-tier lookup, the upstream-tier lookup (when a candidate was found), and the PR-body fallback all came back empty. A `none` or `ambiguous` upstream-extraction result means only the packaging tier's own emptiness matters — the upstream tier contributes nothing to this determination. A raw compare/diff view between two tags never counts as a changelog found, at any tier, for any datasource — including when that bare link is the only thing the PR-body fallback's own section offers — only an actual GitHub Release, a `CHANGELOG.md` section, or the PR body's own genuine itemized Release Notes content does. Whenever more than one registry-metadata tier returns content (docker's packaging and upstream tiers both resolving a changelog), every downstream scan — the breaking-change-callout scan (step 12), the Security advisory scan (step 15), and the Opportunity scan (step 16) — reads the combined text of every such tier that returned content, not just whichever tier resolved first; each tier can independently carry relevant content (the packaging repository for the image's build/runtime interface, the upstream repository for the software's actual behavior). The PR-body fallback's text feeds only the "changelog found" check above and step 12's breaking-change-callout scan — never the Security advisory scan (step 15) or the Opportunity scan (step 16), since Renovate truncates a very large changelog when rendering the PR body, so it can't be assumed to enumerate every intermediate version the way a direct range-fetch can; the fallback exists only to answer "changelog found," never to supply the range those two scans require. The full old→new release range is always fetched once a source is found via the fixed registry-metadata order above (at either docker tier), for every bump size and regardless of `--no-opportunities` — GitHub Releases already return every release, so keep every entry whose tag falls in the old→new range instead of only the latest; for `CHANGELOG.md`, read every dated or versioned section between the old and new version headings, not just the top one. This full range is what the unconditional Security advisory scan (step 15) reads. Step 16's Opportunity scan still only reads this same range for a minor or major bump when `--no-opportunities` wasn't passed — nothing about Opportunity's own trigger condition changes, only the fact that the range it reads is no longer fetched conditionally on its behalf alone. 12. If any changelog or release notes text was found in step 11 (the combined text of every tier that returned content, for docker, plus the PR-body fallback's text when it resolved `found`), scan it for an explicit breaking-change callout (a "Breaking Changes" heading, or prose stating a breaking change) and judge whether it's actually relevant to this codebase's usage — cross- reference the callout's described change (a removed export, a changed function signature, a changed default, a removed collection role) against the call sites found in step 14. A callout naming something this codebase never touches does not count as relevant. 13. Check CI status for the PR: `gh pr checks ` — classify as `failing`, `pending` (checks exist but haven't finished), or `passing` (no failing or pending checks). 14. Compute blast radius: count the distinct tracked files in the current repo using this dependency, searched per the PR's resolved datasource: - **npm**: files importing or requiring the dependency — `git grep -lE "['\"](/|['\"])" -- '*.js' '*.jsx' '*.ts' '*.tsx' '*.mjs' '*.cjs'`. - **docker**: files naming the image — `git grep -l "" -- '*Dockerfile*' 'docker-compose*.yml' 'docker-compose*.yaml'`. - **pypi**: files importing the package — `git grep -lE "^\s*(from|import)\s+" -- '*.py'`. - **ansible-galaxy**: playbooks using the collection's fully-qualified name — `git grep -l "\.\." -- '*.yml' '*.yaml'`. Treat the count as **large** when it exceeds 10 distinct files, regardless of datasource. Ten is the point past which reviewing every call site by hand stops being realistic inside an ordinary PR review — below it, a maintainer could still plausibly open every call site directly and check it themselves if they chose to, so a clean changelog is enough to stand on its own; above it, the sheer count is itself the practical reason a bump needs a closer look, independent of what the changelog says. This applies identically whether the dependency sits in a production or dev-only role — placement is reported as context (step 19) but never changes the verdict. ## Running the Security advisory scan 15. For every dependency, regardless of bump size and regardless of `--no-opportunities`: write the combined changelog text gathered in step 11's range-fetch (never the PR-body fallback's text) to a file and run `node ${CLAUDE_SKILL_DIR}/scripts/detect-security-advisory-cli.js ` once per dependency. **Execute this script directly — it deterministically checks for an explicit CVE identifier, a GitHub Security Advisory ID, a "Security" heading, or explicit urgency/vulnerability language, OR-combined, never re-derived by hand.** A dependency with no changelog text at all (step 11 found nothing) or whose text matches none of the four signals produces no Security advisory output for that dependency — not an empty placeholder. A finding here is never cross-referenced against this codebase's call sites the way step 12's breaking-change callout and step 16's Opportunity are — a security disclosure applies regardless of which APIs this codebase actually calls — and it never changes the verdict computed in step 17, regardless of tier. ## Running the Opportunity scan 16. For a minor or major bump (step 10) only, and only when `--no-opportunities` wasn't passed: scan the combined changelog text gathered in step 11's range-fetch (the widened range; never the PR-body fallback's text) for two kinds of finding only — a newly-added capability, or an existing capability the dependency now marks deprecated — no other category (a performance note, a config-only addition) counts. Keep a finding only when it's actually relevant to this codebase's usage, cross-referenced against the same call sites found in step 14 — the same relevance test step 12 already applies to a breaking-change callout, no new codebase search. There's no cap on how many findings survive this filter per dependency. A patch or indeterminate bump, a `--no-opportunities` run, or a dependency with nothing relevant found, produces no Opportunity output at all for that dependency — not an empty placeholder — and this never changes the verdict computed in step 17, regardless of what's found or how many findings there are. ## Computing the verdict, per dependency 17. Compute the bump size and the verdict together by running `node ${CLAUDE_SKILL_DIR}/scripts/compute-verdict-cli.js --old-version --new-version --changelog-found --breaking-callout --ci-status --blast-radius-large `, using the facts gathered in steps 10–14 — classifying the bump size itself needs no configurable threshold, since semver already defines the patch/minor/major boundary (and a non-semver version — common for a `docker` tag or an `ansible-galaxy` collection version — classifies deterministically as `indeterminate`), so it's folded into the same deterministic call rather than judged separately. **Execute this script directly for each dependency — it deterministically implements the decision table below, so the table must never be hand-recomputed or re-derived from the prose.** It prints `{ bumpSize, verdict, reason }` as JSON. The rules it implements: - **Hard-stops**, checked first — any one alone forces `blocked`, and skips baseline and escalation entirely for this dependency: an explicit breaking-change callout relevant to this codebase's actual usage (step 12); a failing CI check (step 13); a major bump with no changelog or release notes found anywhere (step 11) — this hard-stop is inapplicable to an `indeterminate` bump size, since "major" can't be asserted when the version strings don't parse as semver. - **Baseline**, only reached when no hard-stop fired: an indeterminate bump size (a non-semver old or new version) → `needs-review` unconditionally, mirroring the no-changelog-found case below — "I can't tell how big this bump is" must never silently resolve to `safe`; patch or minor bump with a changelog found → `safe`; major bump with a changelog found and no relevant breaking-change callout → `needs-review`, regardless of blast radius (a major bump's baseline is never `safe` — the version jump alone is enough to warrant a human glance even on a clean changelog); patch or minor bump with no changelog found → `needs-review` (this can't honestly reach `safe` — `safe` means a changelog was actually read and found clean, not merely that no danger signal happened to fire — but it also doesn't fit the major-bump hard-stop, which is specifically about major bumps). - **Escalations**, applied to the baseline, each by exactly one tier: large blast radius (step 14); CI pending rather than passing (step 13). `blocked` is reached *only* via a hard-stop — no combination of baseline and escalations ever produces it, even when both escalations fire on the same dependency, and even when the baseline came from an indeterminate bump size. This keeps a genuinely dangerous signal (a hard-stop) from ever being diluted by, or confused with, an accumulation of merely-cautious ones: `needs-review` is the ceiling anything but a hard-stop can reach. ## Rolling up a grouped PR 18. A PR grouping several dependencies gets a per-dependency verdict breakdown (steps 10–17 run once per dependency) plus one overall rollup verdict, shown at the top of the comment, equal to the worst (most severe: `blocked` > `needs-review` > `safe`) verdict among its dependencies — so one risky dependency in an otherwise-boring bundle is never hidden behind the others. Opportunities roll up the same way, but never into a single worst-of value: one Opportunities subsection per dependency that has a finding, none for a dependency that doesn't — mirroring the verdict breakdown's per-dependency shape without a rollup verdict of its own, since an Opportunity is never ranked against another. A Security advisory finding (step 15) is likewise computed per dependency and never rolled into a single worst-of value or the overall verdict, for the same reason — how it's rendered for a grouped PR is settled by whatever comment-composition convention is current, not fixed here. ## Writing the Agent brief 19. Only for a dependency (or PR, if ungrouped) whose final verdict is `blocked`: name the concrete call sites to inspect (the file list from step 14's blast-radius search, not just a count), and point to the specific changelog or release-notes section that triggered the hard-stop. For a `docker` dependency whose hard-stop is the major-bump/no-changelog rule (step 11), name both repositories checked by `owner/repo` — the packaging repository, and the upstream repository too when step 11's extraction found one — even though neither had a changelog, so a follow-up agent starts from "these repositories were already checked and came back empty" instead of re-deriving the dual-repo resolution from scratch. A non-docker dependency's brief is unaffected — it never had a second repository to name. If the hard-stop was a failing CI check, name the specific failing check(s) instead of a changelog section. If the changelog links a migration or upgrade guide and its own text isn't enough to say what needs to change at each named call site, fetch that guide now — the one point in this skill's flow where reading a migration guide is in scope — and cite the specific section relevant to the flagged change. Never write an Agent brief for `needs-review` — that tier means a human should glance and decide, not that information is missing. ## Posting the comment 20. Compose one comment body per PR following the literal shape in `${CLAUDE_SKILL_DIR}/COMMENT-SKELETON.md` — copy that file's structure rather than re-deriving the comment's shape from prose. It fixes the section order (marker, tier line, per-dependency breakdown, Security advisories, Agent brief, Opportunities) and the table-vs-prose choice for the per-dependency breakdown; this flow feeds it the marker string (``, used for the validation gate below and the idempotency check in step 22, never shown in the rendered comment), the tier line's reason from step 17, step 18's per-dependency rollup (including each dependency's production/dev-only placement), step 19's Agent brief section when one was produced, each dependency's Security advisory finding from step 15 when present, and — kept in its own "Opportunities" section, separate from both the verdict and the Agent brief — each dependency's findings from step 16, omitted entirely (no placeholder line) for a dependency step 16 produced nothing for. 21. Before any comment write executes for this run, validate every composed body: run `node ${CLAUDE_SKILL_DIR}/scripts/validate-comment-body-cli.js ` for each PR's body from step 20. **Execute this script directly for every PR in the batch before posting any of them — it is the machine-checkable gate for the whole run, not a manual double-check.** It confirms the verdict is one of the three valid tiers, the idempotency marker appears exactly once, the tier line's label matches the computed verdict, an Agent brief section is present if and only if the verdict is `blocked` and — when present — its body is fenced in a ` ```text ` block, and any "Opportunities" heading in the body is followed by real content rather than an empty section or boilerplate empty-state text. A PR whose body fails validation is skipped for posting — report it in step 23 alongside the reason validation gave, rather than letting a malformed comment reach a real PR — while every other PR in the batch still proceeds. 22. For every PR whose body passed step 21's validation: search the PR's existing comments for the marker: `gh api repos///issues//comments --jq '.[] | select(.body | contains("renovate-triage:verdict")) | .id'`. If a match exists, update it in place — `gh api -X PATCH repos///issues/comments/ -F body=@` — rather than posting a second one. If no match exists, create it — `gh pr comment --body-file `. Invoking the skill is sufficient authorization to write or update every comment touched in the run; there is no separate per-PR confirmation prompt beyond step 21's validation gate. ## Reporting 23. Report in-session, in addition to the PR comments: every PR checked, its verdict (or per-dependency breakdown for a grouped PR), whether its comment was created or updated, which PRs or dependencies received a new Security advisory finding (step 15) or a new Opportunities section (step 16), every PR skipped for a mixed or unresolved datasource (step 8), every PR skipped for having no adapter for its resolved datasource (step 9), every PR skipped for detection being unavailable (step 7), and every PR skipped for failing step 21's validation gate — each with the reason why. On a no-target scan that found zero open Renovate PRs, this report is exactly the "no open Renovate PRs found" line from step 3 — never silence. ## Worked example A synthetic scenario set, fabricated for this dry run and discarded afterward — never committed, so a fixture PR can't be mistaken for a real one — covering each hard-stop, baseline, and escalation individually, the grouped-PR rollup, one fixture per datasource, each Opportunity-scan shape, the docker adapter's dual-repo lookup, and the Security advisory scan. See `FIXTURES.md` for the full fixture table and walkthrough, and for the comment-idempotency check.
