intel-canary

intel-canary is a skill for Claude Code, Codex from Generous-Corp/pulp. It costs 95 tokens per session (3,403 once invoked), scanned A, original, MIT.

A maintenance guide for checking whether Pulp’s macOS Intel and universal builds remain supported. It describes a portability lint, architecture-specific checks, and several automated test workflows.

In plain words
What is it for?
Use it when changing cross-architecture build settings, portability rules, test exclusions, or the macOS Intel and release checks.
Why use it?
It helps catch accidental regressions in Intel support and explains when a failed timing test reflects emulation or a test-list mismatch rather than an Intel code defect.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

intel-canary scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Intel canary skill

Pulp ships macOS arm64 as usable and macOS x86_64 / universal as experimental. This skill owns the machinery that keeps the Intel story from silently regressing. The full design, tiering, and the honest catch/miss list live in docs/guides/intel-support.md — read it first.

The Tier-1 Rosetta lane measures logic, not speed

intel-portability.yml runs x86_64 binaries under Rosetta on an arm64 runner, at roughly a third of native speed. Anything asserting a wall-clock budget therefore reports the emulator.

That lane went red for seven consecutive runs on exactly three of 16,314 tests, all timing-bound: heritage-performance (labels performance quality-lab), a CompiledTempoMap randomized-map Timeout, and process-deadline-selftest. None was an x86_64 defect.

The cause was a drifted exclusion list: build.yml excludes performance|bench|quality-lab on PR runs, this lane excluded only validation|slow. When adding a timing-sensitive label or a deadline test, update both — and remember --repeat until-pass:2 only absorbs a single flake, so a consistently slow test fails twice and reds the lane.

A red here is advisory and blocks nothing, which is precisely why it can sit red for days while burning ~52 minutes of hosted macOS per triggering PR.

What this skill covers

  • tools/scripts/intel_canary_lint.py — the Tier-0 static lint (5 classes).
  • tools/scripts/intel_canary_allowlist.txt — its exemption list.
  • tools/scripts/test_intel_canary_lint.py — the lint's self-test.
  • The PULP_INTEL_CANARY option in the root CMakeLists.txt.
  • The Tier 0-4 workflows: build.yml (canary step), intel-portability.yml (Tier 1 advisory PR lane), nightly-intel.yml (Tier 2), and the universal-crosscheck job in nightly-intel.yml (Tier 3, nightly), plus the dedicated physical Intel selector and supervisor (Tier 4, advisory).

Note: the Tier-3 universal check only validates a universal build — it publishes nothing, and the release ships THIN per-arch binaries. It lives in nightly-intel.yml's universal-crosscheck job (nightly), NOT on the release path: a redundant canary for an artifact we do not ship must never be able to block or starve a release. intel-portability.yml covers Intel at PR time.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

intel-canary is a skill published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 95 tokens to every session and 3,403 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
