From 0cb0ff2316b05e833119aeae9cc73a0a14329aeb Mon Sep 17 00:00:00 2001 From: Dimitri Kennedy Date: Mon, 19 Oct 2026 11:46:05 -0400 Subject: [PATCH 01/12] feat(agents): privacy-reviewed hack-feedback skill Add a plugin-only hack-feedback skill that drafts reports about Hack itself offline: observed and expected behavior, one honest reproduction status, evidence tagged observed/source/reported/inferred, a friction category, sanitized duplicate search and an attachment list. Posting needs a destination the user confirms and an explicit yes for the exact payload, and goes through the user's own tooling; Hack ships no sender. The skill, its issue-template and examples references, and the new .github/ISSUE_TEMPLATE/hack-feedback.md render from one typed contract in src/agents/feedback-review.ts through the plugin generator. The same module holds the reference sanitizer and the posting gate the skill describes, exercised with a mock sender over synthetic secret, path, URL, config, log-instruction, duplicate, partial-reproduction, denial, edit and failed-send fixtures (HACK-1138).

`KEY=<x>leak` is redacted. - New `hostname` redaction kind for routed `*.hack` and private-suffix hosts without a scheme; paths under /root, /srv, /Volumes, /workspace and other roots plus Windows drive paths; IPv6; truncated (16+ hex) digests; `Authorization: token ...` headers. - Public-URL allowlist parses the URL and rejects dot segments, encoded dots, queries and free-text fragments. - Embedded-instruction filter targets addressed instructions and approval claims instead of any "send the report" phrase. - attemptFeedbackSend treats a synchronous sender throw as a failed attempt and consumes the approval; comment destinations need a positive integer issue number. - Tests cover each case, including attachment-only edits after review and attachment sanitizing at render time; 18 targeted mutations all killed.

Bearer values that start with `<` are redacted too. The sanitizer now removes JSON, syslog, Go-style and clock-prefixed log lines; redacts `db_pass`, `*_key`, cookie and session-id values, secret- store envelope fields at any length, project paths under `~/.hack`, `$HOME`, `/opt` and `/var/lib`, and hosts with a private inner label; and drops more agent-addressed instructions. The send gate counts an attachment as listed only on a visible line of the Attachments section, so a listing inside an HTML comment or raw HTML is refused. Drafts sanitize attachment names before listing them. New tests cover the attachment-name privacy check and the URL fragment allowlist, which no test exercised before.

Removing everything from `<!--` to the next `-->` could remove a live `<details>` that GitHub renders, through `<!-->`, `<!--->` or a `<!--` inside a code span, so such listings now fail closed. A quoted placeholder is exempt only when it is the whole value: text or another quote glued after the closing quote continues the value and is redacted with it. The sanitizer also redacts `-pVALUE` and `-p VALUE` for MySQL and MariaDB clients only, redacts a bare `auth` key only with a secret-shaped value, and keeps the closing backtick, parenthesis or quote after a redacted bare value.

Such a block anywhere in the body now cancels the listing. GitHub also drops an unreferenced footnote with the lines indented under it, so a footnote definition in the section cancels the listing and a line indented by four or more spaces, or a tab, never lists an attachment. A redaction now also keeps sentence punctuation after a closing backtick, parenthesis or quote, so `` `--token=VALUE`. `` keeps its closing backtick.
