-
connorads Bundle Supply Chain HardeningHarden software supply chains across ecosystems (npm/pnpm/bun/yarn/aube, uv/pip, Cargo, GitHub Actions/aqua) by reasoning about what installing or importing a dependency actually executes, then choosing controls: release-age quarantine gates, install-script and load-time trigger removal, lockfile pinning and checksums, provenance/SLSA verification, and osv-scanner malware detection. Use when hardening a project or machine/global config (new or incremental); when converting age-gate settings/units between package managers; when a gate fires mid-task - a blocked install or build script, an age-gate or provenance refusal, a slopsquatted or unfamiliar package - and you must decide whether to allowlist; when adding a dependency you have not vetted; or when auditing a suspected compromised package. For linter rules, gitleaks, and zizmor use the mechanical-enforcement skill; for wiring checks into git hooks use the hk skill; for code-level vulnerability review of your own code use security-review.

garrytan-gbrain Bundle EiirpEverything In Its Right Place. The universal post-work organizer. After any significant work session, EIIRP runs a 7-phase audit: (1) inventory every output, (2) walk taxonomy to decide where each lands, (3) check schema-pack consistency against the brain's actual shape, (4) file enriched brain pages, (5) audit the skill graph for DRY+MECE, (6) verify resolvability, (7) report. Named after the Radiohead song. Nothing produced during significant work lives only in chat — knowledge becomes permanent, patterns become reusable. Also carries the always-on auto-fire gate: when >=500 words of structured analysis on a user-shared document is about to be delivered, file the brain page first, then deliver the analysis with the link in that same reply.
-

Strips internal ratings, compensation, performance assessments, retention and political dynamics from pages, takes, and facts across the full scan scope (people, companies, meetings, dailies, cross-references — not just people/), verifies with grep + retrieval passes, and purges sensitive git history behind the data-loss-gate confirmation card. Also runs as a report-only re-audit on an existing shared brain.

josiahsiegel Bundle Adr BackfillThis skill should be used to retroactively record an architectural decision that was made in the past but never written up as an ADR — typically surfaced by a doc audit or by a user realising a long-ago shipped change should have been documented.

Tense rule: `adr-drafting` claims "we decided / we're deciding"; `adr-backfill` claims "we decided years ago / back when / before my time / never wrote it down." Refuses when reconstruction confidence is `low` -- routes to `open-questions.md`. Requires evidence in two independent locations and a verbatim honesty clause in the record. Provides: backfill ADR template, confidence rubric, evidence corroboration, honesty-clause boilerplate.
