What is gsd-add-tests?

A testing skill that generates tests for a completed project phase using its user-acceptance criteria and implementation.

Use it after completing a phase to create tests based on what the phase was required to do.

It helps check that the finished work meets the behaviors promised to users instead of relying only on manual inspection.

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 5.1	$0.00018	$0.01265
Opus 5	$0.00009	$0.00633
Sonnet 5	$0.00004	$0.00253
Haiku 4.5	$0.00002	$0.00127

Security

Grade A, and why

gsd-add-tests 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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<gsd_agent_plugin_adapter> This GSD distribution is loaded from an Agent Plugin rather than a fixed runtime home.

Resolve GSD_PLUGIN_ROOT as the absolute directory two levels above this SKILL.md.
Resolve every @../../... execution-context reference relative to this skill directory.
Before running a workflow shell command, replace gsd-sdk with node "$GSD_PLUGIN_ROOT/bin/gsd-sdk.js" and turn any ../../get-shit-done/... command path into an absolute path below $GSD_PLUGIN_ROOT.
Named GSD agent prompts live in $GSD_PLUGIN_ROOT/agents/. If the runtime has no matching registered agent type, spawn an available generic worker/default agent and include the corresponding agents/<name>.md prompt in its task message. </gsd_agent_plugin_adapter>

A. Skill Invocation

This skill is invoked by mentioning $gsd-add-tests.
Treat all user text after $gsd-add-tests as {{GSD_ARGS}}.
If no arguments are present, treat {{GSD_ARGS}} as empty.

B. AskUserQuestion → request_user_input Mapping

GSD workflows use AskUserQuestion (Claude Code syntax). Translate to Codex request_user_input:

Parameter mapping:

header → header
question → question
Options formatted as "Label" — description → {label: "Label", description: "description"}
Generate id from header: lowercase, replace spaces with underscores

Batched calls:

AskUserQuestion([q1, q2]) → single request_user_input with multiple entries in questions[]

Multi-select workaround:

Codex has no multiSelect. Use sequential single-selects, or present a numbered freeform list asking the user to enter comma-separated numbers.

Execute mode fallback:

When request_user_input is rejected or unavailable, you MUST stop and present the questions as a plain-text numbered list, then wait for the user's reply. Do NOT pick a default and continue (#3018).
You may only proceed without a user answer when one of these is true: (a) the invocation included an explicit non-interactive flag (--auto or --all), (b) the user has explicitly approved a specific default for this question, or (c) the workflow's documented contract says defaults are safe (e.g. autonomous lifecycle paths).
Do NOT write workflow artifacts (CONTEXT.md, DISCUSSION-LOG.md, PLAN.md, checkpoint files) until the user has answered the plain-text questions or one of (a)-(c) above applies. Surfacing the questions and waiting is the correct response — silently defaulting and writing artifacts is the #3018 failure mode.

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.

gsd-add-tests is a skill published in the GitHub repository megamen32/LastHumanCommit (2 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 1,265 once invoked, about $0.0001 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 2026-09-12.
