Problem

The nightly CVE remediation run summary only shows the table of discovered issues, rendered by the discover job before Claude runs. When the agent decides not to open a PR for an issue (as in the latest nightly run), nothing in the run summary explains what happened - the run is completely opaque.

Changes

  • Moved the issue table to a post-agent step in the remediate job (if: always()), and added a Notes column the agent can optionally populate. The discover job summary keeps the counts and now points at the remediation job summary for the table.
  • Notes mechanism: the workflow creates $RUNNER_TEMP/cve-remediation-notes/, and the task prompt tells the agent it may write a short per-issue note to <LINEAR-IDENTIFIER>.md (UUID-named files work as a fallback), especially when it decides not to open or update a PR.
  • New render-cve-remediation-summary.sh renders the results table from the discovered issue metadata plus the note files: notes are flattened to a single line, trimmed, truncated at 500 characters, and pipe-escaped; titles keep their existing pipe escaping.
  • Issue metadata is handed to the remediate job via an artifact (cve-remediation-issues) instead of a job output, because identifiers contain the Linear team key and job outputs containing secret values are blocked by redaction (the existing needs.discover.outputs.issues guard in the tests still holds).
  • Tests: test-cve-remediation.sh now functionally tests the renderer (identifier- and UUID-keyed notes, pipe/newline escaping, missing note) and asserts the workflow wiring (artifact handoff, notes prompt, if: always() reporting step, Notes column).

Verification

  • .github/scripts/test-cve-remediation.sh - all tests pass
  • .github/scripts/test-vulnerability-triage.sh - all tests pass
  • Both workflow files parse as valid YAML

Low Risk
Changes are limited to GitHub Actions scripts and workflow reporting; they do not touch application runtime, auth, or data paths.

Overview
The CVE remediation workflow moves the issue table out of the discover job and renders it after the Claude agent runs, so the run summary can reflect what actually happened—not just what was queued.

A new render-cve-remediation-summary.sh builds a Markdown table (Linear link, priority, status, title, Notes) from discovered issue JSON plus optional per-issue note files. Notes are looked up by Linear identifier or issue UUID, flattened to one line, truncated at 500 characters, and pipe-escaped. The discover job now only reports counts and points readers to the remediation job summary; it uploads issue metadata as the cve-remediation-issues artifact instead of passing rich metadata through job outputs (avoids secret redaction on identifiers).

The remediate job downloads that artifact, creates cve-remediation-notes/, copies the renderer to $RUNNER_TEMP before the agent step, and instructs Claude to write optional outcome notes to <LINEAR-IDENTIFIER>.md. A Report remediation results step with if: always() appends the table to the job summary even when the agent fails.

test-cve-remediation.sh adds functional tests for the renderer and workflow assertions for artifact handoff, notes prompt, snapshot ordering, and always-on reporting.

Summary by cubic

The CVE remediation run summary previously showed only the issues discovered before the agent ran, so skipped or unresolved outcomes were invisible. It now renders after the agent runs and includes an optional Notes column that records what happened for each issue.

  • The issue table moved from the discover job summary to a post-agent reporting step in the remediate job that runs if: always(); the discover summary keeps only the counts and points to the new location.
  • The agent can write a short per-issue note to $RUNNER_TEMP/cve-remediation-notes/<LINEAR-IDENTIFIER>.md, falling back to the issue's UUID.
  • A new renderer script flattens note whitespace, truncates notes at 500 characters, pipe-escapes title and note cells, and fails loudly when the issues file is missing or malformed; it's copied to $RUNNER_TEMP before the agent starts so the agent can't modify or delete it.
  • Issue metadata reaches the remediate job via artifact upload instead of a job output, because identifiers contain the Linear team key and would be blocked by secret redaction.
  • Tests cover identifier- and UUID-keyed notes, pipe and backslash escaping, missing notes, note truncation, snapshot ordering before the agent step, and the workflow wiring.

Written for commit 96897b2. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Added a remediation results summary to the CVE workflow with issue links, priorities, statuses, titles, and optional outcome notes.
    • Remediation agents can provide per-issue notes displayed in the final Markdown summary.
    • Results are reported even when remediation encounters an error.
  • Improvements

    • Preserved discovered CVE issue details across workflow stages for reliable reporting.
    • Added validation, truncation, and safe formatting for notes and special characters.
    • Improved handling of missing or invalid remediation inputs.
    • Added temporary artifact storage to support consistent results reporting.

The nightly CVE remediation run summary only showed the issues discovered
before the agent ran, so when the agent decided not to open a PR there was
no visible explanation. Move the issue table to a post-agent step in the
remediation job and add a Notes column the agent can optionally populate
by writing one file per issue into a notes directory.

Issue metadata is handed to the remediation job through an artifact rather
than a job output because identifiers contain the Linear team key and
would be blocked by secret redaction.

Walkthrough

The workflow transfers discovered issue metadata between jobs, collects optional remediation notes, and renders a Markdown results table in the remediation job summary. Tests cover note lookup, validation, escaping, truncation, output formatting, and workflow integration.

Changes

CVE remediation reporting

Layer / File(s) Summary
Result table renderer
.github/scripts/render-cve-remediation-summary.sh, .github/scripts/test-cve-remediation.sh
The renderer validates the issues file, resolves notes by identifier or UUID, normalizes and truncates note text, escapes backslashes and pipe characters, and emits a Markdown table. Tests validate formatting, truncation, missing-input failure, and fixtures.
Issue artifact and agent notes
.github/workflows/_cve-remediation.yml
The discover job writes and uploads issue metadata as an artifact. The remediation job downloads the artifact, prepares the renderer, and prompts the agent to write optional per-issue notes.
Always-on remediation reporting
.github/workflows/_cve-remediation.yml, .github/scripts/test-cve-remediation.sh
The workflow invokes the renderer after the agent step and appends results to GITHUB_STEP_SUMMARY, including when the agent step fails. Workflow assertions validate artifact transfer, renderer snapshotting, renderer usage, always-run reporting, and the notes column.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 96897

This change is limited to CVE remediation workflow reporting and adds post-run notes without introducing an actionable merge-blocking risk; it is merge-ready after normal checks and review.

Address review findings: escape backslashes before pipes in table cells,
fail loudly when the issues artifact is missing or malformed, exercise
note truncation in the tests, and scope the always() assertion to the
report step.

The report step ran the renderer from the untracked workflow-assets
checkout inside the workspace, which the agent step can modify or delete
(e.g. a git clean). Copy the script to the runner temp directory before
the agent starts and execute that snapshot instead.
