fold: Skill for Claude Code

.claude/skills/fold-release/SKILL.md

fold-release is a skill for Claude Code from fold-run/fold. It costs 81 tokens per session (2,162 once invoked), scanned A, original, Apache-2.0.

A release procedure for fold, including checks, changelog updates, version changes, publishing, and verification. A release is started by pushing a specially named Git tag, which triggers the build workflow.

In plain words
What is it for?
Use it when preparing and publishing a fold release, including checking code, updating the Helm chart version, watching CI, and verifying artifacts.
Why use it?
It reduces the risk of publishing an untested build or skipping required approval before Git changes and release actions.

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

fold-release 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 2mo ago.

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.

How it starts

The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fold release workflow

Releases are annotated-tag-driven: pushing vX.Y.Z triggers .github/workflows/release.yml (goreleaser). The version string is stamped via -ldflags "-X github.com/fold-run/fold/gateway.ldflagsVersion=..." — goreleaser handles this; never hardcode a version in source.

Cardinal rule: every git-touching step needs the user's explicit, per-step approval. "Release it" authorizes the process, not each push. Finish and report each step, then wait for the go-ahead before the next. Never batch commit+push+tag on a single approval.

Steps

  1. Verify before anything touches git. Run the full gate:

    • make check (fmt-check, tidy-check, vet, build, race, lint)
    • make bench if the proxy path changed (gate: added p50 < 5 ms)
    • make conformance if behavior through the gateway changed (40/40)
    • make helm-check if deploy/helm/ changed Report results with real output. Stop here if anything fails.
  2. Bump the console pin. gateway/console is vendored from fold-run/fold-console at the commit in scripts/sync-console.sh, and nothing bumps it on a schedule any more — console-sync.yml is workflow_dispatch only, because the weekly robot generated more repair work than console changes. The release is where a human is already reading a diff, so it is where the pin moves.

    git ls-remote https://github.com/fold-run/fold-console.git refs/heads/main
    

    If that SHA differs from CONSOLE_COMMIT, re-vendor and re-verify — the assets are a supply-chain input, so this is a real review, not a rubber stamp:

    CONSOLE_COMMIT=<40-hex> make sync-console
    git diff --stat -- gateway/console      # read what changed
    make console-check && make test
    

    Then run the security-auditor agent over the diff, as the workflow's own PR body demands. If the console has not moved, say so and continue — a release with a stale-but-current pin is normal.

  3. Pick the version. The repo is under the v1 compatibility contract (README "API stability"): patch for fixes, minor for backwards-compatible features, major only for a deliberate contract break (which needs its own conversation). Confirm the number with the user.

What this file has done since we first saw it

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.
