Magpie Security Issue Sync

security-issue-sync

This skill reconciles a single security issue in `` with:

1. the GitHub issue itself — comments, labels, milestone, assignee, description fields;
2. the email thread on `` that originated the report (and any follow-ups);
3. any pull requests in ` or ` that reference or fix the issue;
4. the handling process documented in [README.md](../../README.md).

Golden rule 1 — propose before applying. Every change this skill performs is a proposal. The user running the sync must explicitly confirm each update before it is applied. Do not mutate GitHub state, do not send email, do not create, close, or edit anything without a clear "yes" from the user for that specific action. Drafts are always created as Gmail drafts, never sent directly.

**Golden rule 2 — every ` reference is clickable in the surface it lands on.** Whenever this skill mentions the tracking issue, any other issue, a ` PR, a specific issue comment, a milestone, or a label from this repository — in the observed-state dump, in the proposal, in the confirmation prompt, in the apply-loop output, in the regeneration output, in the recap, in status-change comments posted to the issue itself, anywhere — the reference must be one click away in whatever surface it lands on:

• On markdown surfaces (the proposal body and status-change

comments posted to `, the regenerated CVE JSON's reference list, any draft email reply text destined for the Gmail thread): use the markdown link form per the "Linking issues and PRs" section of [AGENTS.md`](../../AGENTS.md):

• Issue: [#221](https://github.com//issues/221)

(or [#221](https://github.com//issues/221) when the repository is already obvious from context, e.g. inside a status-change comment on that same issue).

• PR: [#NNN](https://github.com//pull/NNN)

(.../pull/N, not .../issues/N).

• Comment: link to the #issuecomment- anchor, e.g.

[#216 — issuecomment-4252393493](https://github.com//issues/216#issuecomment-4252393493).

• Milestone: link to https://github.com//milestone/

(not the title), because milestone titles can change and the number is stable. Example: [3.2.2](https://github.com//milestone/42).

• On terminal surfaces (the apply-loop progress messages,

the confirmation prompt, the recap printed to the user's terminal at the end): wrap the visible short form (#NNN) in OSC 8 hyperlink escape sequences (\e]8;;\e\\#NNN\e]8;;\e\\) so modern terminals (iTerm2, Kitty, GNOME Terminal, WezTerm, Windows Terminal, …) render the short text as clickable. Where OSC 8 is unsupported (CI logs, dumb terminals), fall back to printing the bare URL on the same line after the number.

Bare #NNN / #NNN with no link wrapper of any kind is never acceptable — not in terminal output, not in posted comments.

Self-check before presenting any user-visible text (proposal body, recap body, status-comment body, apply-loop progress messages): grep the text for bare #\d+ and bare #\d+ tokens that aren't already inside a markdown link or an OSC 8 wrapper, and convert any match to the appropriate clickable form for that surface. If the scrub finds a reference the skill does not have the full URL for yet, look it up with gh issue view --repo --json url --jq .url before emitting. Tracker URLs and #NNN identifiers are public-safe per the [Confidentiality of ``](../../AGENTS.md#confidentiality-of-the-tracker-repository) rule (the page they point at is access-gated, so the link itself does not leak contents); what stays private is the verbatim content of the tracker — comment quotes, label transitions, body excerpts, severity assessments — and, before the advisory ships, the security framing of a public PR.

Adopter overrides

Before running the default behaviour documented below, this skill consults [.apache-magpie-overrides/security-issue-sync.md](../../docs/setup/agentic-overrides.md) in the adopter repo if it exists, and applies any agent-readable overrides it finds. See [docs/setup/agentic-overrides.md](../../docs/setup/agentic-overrides.md) for the contract — what overrides may contain, hard rules, the reconciliation flow on framework upgrade, upstreaming guidance.

Hard rule: agents NEVER modify the snapshot under /.apache-magpie/. Local modifications go in the override file. Framework changes go via PR to apache/magpie.

---

Snapshot drift

Also at the top of every run, this skill compares the gitignored .apache-magpie.local.lock (per-machine fetch) against the committed .apache-magpie.lock (the project pin). On mismatch the skill surfaces the gap and proposes [/magpie-setup upgrade](../setup/upgrade.md). The proposal is non-blocking — the user may defer if they want to run with the local snapshot for now. See [docs/setup/install-recipes.md § Subsequent runs and drift detection](../../docs/setup/install-recipes.md#subsequent-runs-and-drift-detection) for the full flow.

Drift severity:

• method or URL differ → ✗ full re-install needed.
• ref differs (project bumped tag, or git-branch

local is behind upstream tip) → ⚠ sync needed.

• **svn-zip SHA-512 mismatches the committed

anchor** → ✗ security-flagged; investigate before upgrading.

---

Inputs

Before running the skill, you need a selector that resolves to one or more issues:

• Issue number: #185, 185, #212, #214, #218.
• CVE ID: CVE-2026-40913 — looked up by matching against each

open issue's CVE tool link body field.

• Title substring: JWT, KubernetesExecutor — fuzzy title match;

always confirm the resolved set with the user before dispatching.

• Label: announced, pr merged, cve allocated —

all open issues carrying that label.

• All open issues: sync all / sync all open — the 21-ish-issue

default for a triage sweep.

Selectors can be combined (sync #212, CVE-2026-40690, JWT) and the skill resolves each independently. See the "Bulk mode — syncing many issues in parallel" section below for the full resolution table and the confirmation prompt pattern.

Optional: a hint from the user about what they want to focus on ("has this been CVE-assessed yet?", "is the PR merged?", etc.). Use it to prioritise but still run the full sync.

If the user does not supply any selector, ask for one before doing anything else.

---

Bulk mode — syncing many issues in parallel

When the user asks for a bulk sync ("sync all open issues", "sync #212, #214 and #218", "refresh state of everything that is still cve allocated", or a triage-sweep variant), switch into bulk mode.

The full orchestration contract — bucketing by CVE-record impact, parallel subagent fan-out, merged-proposal review shape, confirmation syntax, hard rules, when bulk mode is NOT appropriate — lives in [bulk-mode.md](bulk-mode.md). Read it before invoking a bulk run.

Prerequisites

The skill needs:

• At least one configured mail-source backend per

[/project.md → Mail sources](../..//project.md#mail-sources), collectively covering read_thread (for the reporter thread) and — if status-update drafts will be proposed — create_draft. The skill uses the abstract operations defined in [tools/mail-source/contract.md](../../tools/mail-source/contract.md) and the contract's [resolution rule](../../tools/mail-source/contract.md#resolution-rule--which-backend-runs-an-operation) to pick a backend per op at run time. Reference adapters: [gmail](../../tools/gmail/tool.md), [ponymail](../../tools/ponymail/tool.md), [imap](../../tools/mail-source/imap/README.md), [mbox](../../tools/mail-source/mbox/README.md).

• gh CLI authenticated with collaborator access to

` (read + issue-write) and ` (read is enough — the sync only reads PR state on that repo).

• Outbound HTTPS to pypi.org, artifacthub.io, and

`` — the sync curls these to detect released versions and to find advisory archive URLs.

See [Prerequisites for running the agent skills](../../docs/prerequisites.md#prerequisites-for-running-the-agent-skills) in docs/prerequisites.md for the overall setup.

Step 0 — Pre-flight check

Before reading any tracker state, verify:

1. **Mail-source backends per

/project.md → Mail sources are available — for each declared backend run its trivial health probe (per its adapter doc), record the result in the observed-state bag, and apply the [contract's resolution rule](../../tools/mail-source/contract.md#resolution-rule--which-backend-runs-an-operation) to figure out which backend serves which op for this run. A mandatory: yes backend that is unavailable is a hard stop**; mandatory: no backends degrade quietly and the affected ops are skipped per the contract.

1. gh is authenticated with access to `` —

gh api repos/ --jq .name must return `. A 401/403/404 means the user needs gh auth login` or collaborator access.

1. PonyMail MCP status. Whether this is a hard gate depends on

the manifest: if /project.md → Mail sources declares ponymail with mandatory: yes (the ASF default), PonyMail is a pre-flight prerequisite and the outcomes below that "degrade quietly" become hard stops instead. Call mcp__ponymail__auth_status() once. Four outcomes:

• Authenticated session — record

ponymail_enabled: true, ponymail_authenticated: true in the skill's observed-state bag. Downstream steps use PonyMail MCP as the primary read path for the mailing-list queries documented in 1c / 1d / 1e / 2b / 2c; Gmail becomes the fallback. This is the normal configuration for -authenticated triagers.

• No session / expired session —
• mandatory: yes (ASF default): stop. Surface

"mandatory mail-source backend ponymail is registered but not authenticated — run mcp__ponymail__login() and re-invoke". Private-list reads need the LDAP session, and ASF triagers are -authenticated, so an unauthenticated session is a hard stop, not a Gmail-only fallback.

• mandatory: no: record

ponymail_enabled: true, ponymail_authenticated: false, warn ("PonyMail MCP is configured but not authenticated — run mcp__ponymail__login() if you want this session to use it; otherwise Gmail will serve all reads"), and proceed with Gmail as the primary read path.

• MCP tools not available (the mcp__ponymail__* tools

are absent from the current session's tool list) —

• mandatory: yes (ASF default): stop. Surface

"mandatory mail-source backend ponymail unavailable: MCP not registered; run aborted — register it per tools/ponymail/tool.md (install from the latest main of apache/comdev) and re-invoke".

• mandatory: no: record ponymail_enabled: false and

silently proceed Gmail-only. When the manifest declares ponymail with mandatory: no and .apache-magpie-overrides/user.md sets tools.ponymail.enabled: false (or omits the block), skip this sub-step; Gmail is the only read backend. See [tools/ponymail/tool.md](../../tools/ponymail/tool.md) for the one-time setup instructions.

1. Selector resolves to a concrete issue (or set of issues) —

if the user said sync NNN but the number does not exist in ``, stop before Step 1 and ask which issue they meant.

1. Privacy-LLM contract. This skill reads ``

bodies (and may read ` content when escalating) that may contain third-party PII. Run the gate-check first — non-zero exit is a hard stop, and pass --reads-private-list` because escalation paths in this skill may read -private foundation lists:

``bash uv run --project /tools/privacy-llm/checker \ privacy-llm-check --reads-private-list ``

Plus the rest of the pre-flight items in [tools/privacy-llm/wiring.md](../../tools/privacy-llm/wiring.md#step-0--pre-flight) — ~/.config/apache-magpie/ is writable, the configured collaborator source is reachable, the redaction-tuning knobs are loaded into the observed-state bag. Subsequent body reads in Step 1 (gather current state) follow the [redact-after-fetch protocol](../../tools/privacy-llm/wiring.md#redact-after-fetch-protocol); Step 4 outbound drafts follow the [reveal-before-send protocol](../../tools/privacy-llm/wiring.md#reveal-before-send-protocol) when (and only when) the rendered draft references a third-party identifier.

1. Disclosure governance flags from /security-intake-config.md.

If the file exists, read the disclosure_governance block and load these three keys into the observed-state bag for use in Steps 1 and 2b:

• window_days — integer; the CVD window in calendar days from first

receipt to public disclosure. Used in Step 1a to flag trackers past their disclosure deadline.

• grace_period_days — integer; the additional days granted after a fix

ships before the team is expected to publish the advisory. Used in Step 1a to determine whether the grace period has also lapsed.

• pre_announce_distributors — boolean; when true the team maintains

a distributor embargo list and the skill proposes a pre-announcement draft once the fix is in a pending release. Used in Step 2b.

If the file does not exist or the disclosure_governance block is absent, silently default to window_days: 90, grace_period_days: 14, and pre_announce_distributors: false. A missing file is not a stop condition — adopters who have not yet created this config receive the same ASF defaults the skill has always applied.

If any check fails (other than PonyMail, which degrades quietly), stop and surface what is missing. Do not proceed to Step 1 on a partial setup — half the observations would be wrong and the proposals downstream would be junk.

---

Step 1 — Gather the current state

Read the GitHub issue, find referenced PRs, find the real reporter and the original mailing-list thread, mine comments + mail for actionable signals, check Gmail for CVE-reviewer comments, locate the process step, and (on recently-closed trackers) check the cve.org publication state. (For ASF projects with release-vote gating, also detect active release-vote threads.)

The full per-sub-step recipe — 1a through 1h, with the Gmail search queries, PonyMail fallback path, signal-detection rules, and process- step decision table — lives in [gather.md](gather.md).

Step 2 — Build a proposal (do not apply anything yet)

Produce a single, compact summary for the user with three sections:
