A manual quality-assurance harness for the senpi coding agent. It runs the real command-line tool in an isolated temporary environment and checks what users can observe.

Use it after changing senpi's AI, agent, coding-agent, or terminal interface packages. It tests four communication channels and includes self-checks for its helper scripts.

It catches problems that type checks and automated unit tests may miss. It also keeps tests away from real credentials and user data.

senpi-qa — Skill for Claude Code and Codex by code-yeongyu: A manual quality-assurance harness for the senpi coding agent.

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.

Model	Per session	Once invoked
Fable 5	$0.00201	$0.02909
Opus 5	$0.00101	$0.01455
Sonnet 5	$0.00040	$0.00582
Haiku 4.5	$0.00020	$0.00291

Security

Grade A, and why

senpi-qa 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 4d ago.

The scan reads SKILL.md. This mod also ships 50 executable files (scripts/anthropic-oauth-callback-bind-fallback-probe.mjs, scripts/claude-sdk-oauth-auth-spike.mjs, scripts/claude-sdk-oauth-autocompact-settings-probe.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

senpi QA

QA the senpi coding agent (packages/{ai,agent,coding-agent,tui}) by driving the REAL CLI — not by reading code or trusting unit tests. Each channel runs the agent from source via tsx in an isolated sandbox and asserts observable behavior, so a passing run is evidence the user-facing surface actually works.

Every helper script ships a --self-test (or --self-check) that asserts its scenario against this machine. The scripts are therefore both the QA tools and their own regression checks.

Golden rules (read before running anything)

Isolation is mandatory. Everything spawns the CLI with SENPI_CODING_AGENT_DIR / SENPI_CODING_AGENT_SESSION_DIR pointed at a temp sandbox and PI_OFFLINE=1. QA must never write into the real ~/.senpi. scripts/lib/common.mjs does this for you — use it.
Never read or modify the real credentials. ~/.senpi/agent/auth.json is the user's real key store. Every script snapshots its sha256 and asserts it is unchanged at the end. If you script a run by hand, do the same (guardRealAuth() in common.mjs).
Deterministic loop = mock loop. To exercise the agent loop without real tokens, use Channel 3 (a local fake model server). Real-provider runs are for final smoke only and must use the user's existing auth, never a new key.
No src/ edits from this skill. It verifies; it does not fix. If QA finds a bug, report it with the captured evidence and let a follow-up change fix it.
The captured artifact IS the evidence. Write it under local-ignore/qa-evidence/<YYYYMMDD>-<slug>/. No artifact == the QA did not happen. local-ignore/ is gitignored — never commit evidence.

Setup (once)

node scripts/devenv-setup.mjs        # installs skill deps (node-pty), wires .env.local + .claude/skills
node .agents/skills/senpi-qa/scripts/lib/common.mjs --self-check   # confirm the harness

common.mjs --self-check confirms the repo resolves, a sandbox is created and auto-removed, a free port is allocatable, and the real auth file is untouched.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

senpi-qa is a skill published in the GitHub repository code-yeongyu/senpi (419 stars, last pushed today), licensed MIT. It adds 201 tokens to every session and 2,909 once invoked, about $0.0010 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 2026-08-30.
