hammer

hammer is a command for coding agents from nguyenvanphituoc/shapeup-sdlc-plugin. It costs 16 tokens per session (153 once invoked), scanned A, original, MIT.

A stop-decision command for a product-building process. It reviews open work, compares the product with what customers use today, and proposes what to remove before shipping.

In plain words
What is it for?
Use it to make a final cut list and receive a proposed ship decision for a tech lead or product owner to confirm.
Why use it?
It gathers scattered unfinished items and checks whether the product has reached a useful baseline. It also handles different ways a work cycle can run out of time or attempts.

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

hammer 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 5d 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.

What it actually says

Use the scope-hammer skill on $ARGUMENTS.

The stop decision. Censuses the open items (QA findings, discovered-ledger rows, attempt-budget hammer proposals), compares the product to the pitch's baseline — what customers live with today, never the ideal — and returns a cut list plus a ship verdict for the TL/PO to confirm.

Handles all three arrival paths: the normal stop (all scopes finished), an exhausted round budget, and an exhausted per-scope attempt budget. The verdict is a proposal — promotion of cut items is the human's call at the gate, not the skill's.

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.
