develop

develop is a command for Claude Code from adrian-d-hidalgo/nestjs-mcp-server. It costs 90 tokens per session (3,839 once invoked), scanned A, original, MIT.

A development command that turns an existing issue specification into a concrete plan and carries out the local code changes. The specification describes what must be built and how it will be tested.

In plain words
What is it for?
Use it to develop one specified issue in the current working tree, run its quality checks and QA plan, and write verification notes. It does not merge, release, or publish changes.
Why use it?
It removes the need to repeatedly translate a written specification into implementation steps and separate test work. It also records verification evidence before the work is considered ready to commit.

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

develop 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.

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

Scope is local development only — no merge, no release, no publish.

/specification already decided what must be built and how it will be verified: .project/tasks/issue-<N>/spec.md and test-plan.md. /develop decides how, concretely, against this working tree and then does it. It executes against the SPEC; it does not re-derive the technical analysis and it never edits spec.md — a wrong SPEC is a /specification refine, not something to bend the work around.

The execution plan is ephemeral. It lives in this conversation and is not written to disk. It is specific to the working tree in front of you and stale the moment the code moves; a stale plan on disk is worse than none, because a later session reads it as current. What persists from this command is the evidence: verification.md and notes.md.

This command also performs the verification that Caperifai splits into a separate /test stage: the QA plan is executed and the issue's full acceptance criteria are recorded before anything is declared ready to commit.

For anything unclear — an acceptance criterion whose success signal is undefined, a SPEC claim the current code contradicts — emit questions or verify against the code. Never invent a file, a dependency, or a plan detail to fill a gap.

Scope discipline (hard). The plan and the execution cover EXACTLY the issue's scope — what it implies, nothing more. developer does not extend into another issue's work, however incomplete the whole looks without it. If something critical to this issue's own delivery is missing, it is surfaced as a blocker and appended to notes.md — never silently built. Getting creative and implementing the neighbouring piece is the failure this guards against.

Phase 1 — Plan (in-session; stops for your approval)

  1. Check preconditions. issue_read the issue and its comments.
    • No spec.md in .project/tasks/issue-<N>/stop and point at /specification <#N>. The technical analysis belongs there. Prepare nothing. Note that the issue itself will show no sign of whether a SPEC exists — nothing is ever written to it — so the workspace is the only place to check, and an absent spec.md means either the SPEC was never written or the workspace lives on another machine. Either way, do not improvise the analysis here.

    • Blocked by #N unresolved → stop and report.

    • Bug issue with no root cause → stop and point at /debug <#N>.

    • The SPEC declares itself not readystop. Read the **Status:** field, which templates/SPEC.md requires on the third line:

      grep -m1 '^\*\*Status:\*\*' .project/tasks/issue-<N>/spec.md
      

      ready → continue. blocked: <question>stop and report the question. Missing → treat as blocked and say the SPEC predates the field, rather than assuming either way.

      A SPEC is allowed — and expected — to conclude that a requirement admits several materially different designs and that the choice was never made. When it says so, the missing piece is a decision, not code. Building anyway means inventing the design the SPEC deliberately refused to invent, and doing it inside an execution plan, where it reads as settled.

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.
