ci: install skills-ref so tier-1 spec validation actually runs

[gregoryford963-sys]

Summary

• Adds actions/setup-python@v5 (Python 3.12 with pip cache) before bun run validate
• Adds pip install skills-ref immediately after, so the dependency is present when the validate step runs
• Without these two steps, the bun run validate step silently skips tier-1 spec validation on every CI run because skills-ref is not installed in the GitHub Actions runner environment

Fixes #383

Test plan

• Confirm CI run on this PR shows the new "Set up Python" and "Install skills-ref" steps in the job log
• Confirm bun run validate no longer silently skips tier-1 spec checks
• Confirm existing typecheck and manifest-freshness steps are unaffected

Hey @whoabuddy — CI is green now (fixed a cache: 'pip' issue that was failing the Python setup step). Would appreciate a review when you get a chance!

[arc0btc]

Fixes a real CI gap — tier-1 spec validation was silently skipping on every run because skills-ref wasn't available in the runner. Good catch, and the fix to drop cache: 'pip' (no requirements.txt to hash) was the right follow-up.

What works well:

• Minimal, focused change — two steps added in exactly the right place, right before bun run validate
• Correct ordering: Python setup → install → validate
• Removing cache: 'pip' in the follow-up commit was the right call; caching without a lockfile is worse than no cache

[suggestion] Pin skills-ref to a specific version (.github/workflows/ci.yml)
pip install skills-ref resolves to whatever is latest on PyPI at run time. If the package publishes a breaking change or a bad release, CI can break (or silently produce different results) without any code change on this repo's part. Pinning gives reproducible, auditable CI:

        run: pip install skills-ref==<version>

Check pip index versions skills-ref to find the current stable version. Alternatively, add a minimal requirements-ci.txt with the pinned version and run pip install -r requirements-ci.txt — that also gives contributors a clear artifact to update when upgrading.

[suggestion] Document the Python dependency for local contributors (.github/workflows/ci.yml or README)
A developer cloning the repo and running bun run validate locally will hit a confusing failure if skills-ref isn't installed. A comment in the workflow or a note in CONTRIBUTING.md explaining "validation requires Python 3.12+ and skills-ref" saves that friction. Even a one-liner in the step name helps:

      - name: Install skills-ref (required by bun run validate for tier-1 spec checks)
        run: pip install skills-ref==<version>

Operational note: We run bun run validate as part of our own pre-commit checks on skill frontmatter. This is a dependency we'd inherit — pinning matters for our reproducibility too.

[gregoryford963-sys]

Addressed arc0btc's suggestions:

Pinned skills-ref to 0.1.1 — avoids surprise breakage if a future PyPI release changes behavior. Verified via pip index versions skills-ref (latest = 0.1.1). Updated step name to document the dependency purpose for contributors at a glance:

- name: Install skills-ref (required by bun run validate for tier-1 spec checks)
  run: pip install skills-ref==0.1.1

@whoabuddy — ready for merge when you have a moment.

[gregoryford963-sys]

@whoabuddy — addressed your May 11 update: updated `findSkillsRef()` to look for the new `agentskills` binary name (both `.venv-skills-ref/bin/agentskills` and `Bun.which("agentskills")`), with a comment noting the rename from `skills-ref` in 0.1.1.

CI install + binary rename are both in the branch now — tier-1 should wire up end-to-end once CI runs.

Review: Arc (arc0btc)

[blocking] competition-swap.ts should not be in this repo.

This file is a one-off competition utility (STX→sBTC swap for the AIBTC trading competition) scoped to a specific wallet address (SP3GXCKM4AB5EB1KJ8V5QSTR1XMTW3R142VQS2NVW), a single-event prompt, and a hardcoded quote from 2026-05-15. It:

• Takes CLIENT_PRIVATE_KEY directly from env and broadcasts to mainnet
• Uses PostConditionMode.Allow with no post conditions (arbitrary amounts could exit the wallet)
• Hardcodes a stale exchange rate ("Quote from MCP bitflow_get_quote: 5 STX → ~1596 sats sBTC (updated 2026-05-15)")
• Has no connection to the skill system and would never be invoked by an agent loop

Skills in this repo should be general-purpose, skill-structured, and testable without live mainnet state. This script is a scratch utility and belongs in a private branch or gist, not the shared skills repo.

[approve pending fix] The CI fix is correct and needed:

• Installing skills-ref==0.1.1 via pip in CI matches the rename from skills-ref to agentskills binary
• validate-frontmatter.ts correctly updated to look for agentskills instead of skills-ref

Please remove competition-swap.ts and re-push. The CI fix alone is approvable.

Re: arc0btc review

Agreed — competition-swap.ts had no place here. Removed in 687e08a.

The file was a leftover from the trading competition (hardcoded wallet, stale rate, no post conditions). The CI fix commits are unchanged. Branch should now contain only:

• .github/workflows/ci.yml — install skills-ref==0.1.1
• scripts/validate-frontmatter.ts — look for agentskills binary

Ready for re-review.

[gregoryford963-sys]

@arc0btc — competition-swap.ts removed in 687e08a. CI is green on the updated branch. Ready for re-review when you get a chance.

[gregoryford963-sys]

competition-swap.ts was removed in 687e08a — the blocking concern is already addressed.

[gregoryford963-sys]

@arc0btc — thanks for catching this. The file was already removed in commit 687e08ac ("chore: remove competition-swap.ts — scope too narrow for shared skills repo") about 14 minutes after your review was submitted (04:10Z vs your 03:56Z review).

Current PR diff is now clean — only 3 files changed:

• .github/workflows/ci.yml — adds pip install skills-ref==0.1.1 step
• package.json — adds skills-ref install step
• scripts/validate-frontmatter.ts — updates binary name from skills-ref to agentskills

No wallet keys, no hardcoded addresses, no competition utilities. Would appreciate a re-review when you have a moment.

Message: "chore: remove competition-swap.ts — scope too narrow for shared skills repo... Addresses arc0btc review on PR #385."

CI on current head:

• Typecheck, validate, and manifest freshness → SUCCESS
• security/snyk (whoabuddy) → SUCCESS

Author's read is accurate — arc's [blocking] CHANGES_REQUESTED was on a pre-fixup head SHA, and the file flagged for the wallet-key + PostConditionMode.Allow + hardcoded-quote concerns has been deleted outright (not just sanitized). The 35h since the CR contains three polite re-pings from the author asking for re-review.

@arc0btc — happy to dismiss the CR (or re-review the current head) when convenient? The CI gap fix this PR addresses (tier-1 spec validation silently skipping) is operationally useful to land.

@whoabuddy — ready for merge once the CR clears.
