strike: Skill for Claude Code

.claude/skills/smoke/SKILL.md

smoke is a skill for Claude Code from jonathanung/strike. It costs 59 tokens per session (607 once invoked), scanned A, original, Apache-2.0.

A set of offline, product-level checks for the strike-cli command-line and text-based interface. It tests starting the program, sending an echo request, interrupting it, and resuming a session.

In plain words
What is it for?
Use it to build the program, start its echo mode, check its version and command execution, and record whether boot, interruption, and session-resume checks pass.
Why use it?
It catches user-facing problems that unit tests may miss before a release or after changes to the command line, interface, sessions, or authentication. The default checks need no API keys.

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

smoke 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Smoke (strike-cli)

Product-level checks beyond unit tests. Prefer automated commands; fall back to a short manual checklist when automation is missing.

No API keys required for the default path (echo provider).

When to run

  • Changes under cmd/strike, harness/engine, internal/frontend/tui (input/keymap/app), internal/persist/session, internal/product/auth, internal/frontend/host
  • Before cutting a release (with skill release)
  • After CI green when the PR is user-visible

Skip for pure docs/skills (tier A) unless the docs claim a runtime behavior change.

Automated baseline

make build
make run-echo   # must start; quit cleanly (q / ctrl+c per current binds)

If strike binary exists from make build:

./strike version
./strike exec --provider echo "say hi" 2>/dev/null || ./strike exec "say hi" || true

Record the exact flags that work on this revision (exec/provider flags drift — read ./strike -h / cmd/strike).

Checklist (mark each PASS/FAIL/SKIP)

# Path How
1 Boot make run-echo or ./strike --provider echo starts without panic
2 Version ./strike version prints stamped or dev version
3 Echo turn Send a short prompt; assistant text appears (manual TUI or exec)
4 Tool path If tools touched: echo run … or unit-covered tool still OK — note SKIP if not exercised
5 Interrupt If engine/TUI interrupt touched: esc (or documented bind) cancels in-flight turn
6 Resume If session touched: --continue or /session resume loads without corrupt transcript
7 Auth surface If auth touched: strike auth help/list does not crash (no live login required)

Report format

  1. Verdict — PASS only if no FAIL; list SKIP with reason.
  2. Commands — exact lines.
  3. Failures — verbatim.
  4. Not run — what a human should still click-test.

Rules

  • Do not claim product readiness from make test alone when this skill applies.
  • Do not require live provider keys for baseline smoke.
  • Do not skip FAIL by weakening the app; open a bugs-first issue instead.

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.

smoke is a skill published in the GitHub repository jonathanung/strike (5 stars, last pushed today), licensed Apache-2.0. It adds 59 tokens to every session and 607 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings.
