agent-library: Command for Claude Code

.gemini/commands/speckit/speckit.constitution.toml

speckit.constitution is a command for Claude Code, Gemini CLI from bl1nk-bot/agent-library. It costs 0 tokens per session (1,108 once invoked), scanned A, a copy of speckit.constitution, CC0-1.0.

A command that creates or updates a project's constitution: a written set of principles and rules for how the project is built. It also updates related document templates when those principles change.

In plain words
What is it for?
Use it to define or revise engineering principles and synchronize the documents that depend on them.
Why use it?
It keeps project-wide development rules explicit and consistent across future specifications, plans, and tasks.

Command for Claude CodeGemini CLI

Written for Claude Code and Gemini CLI: $ARGUMENTS substitution, but also installed under .gemini/.

This is bl1nk-bot/agent-library's own configuration. It tells Claude Code and Gemini CLI how to work on agent-library itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-library configures →

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

speckit.constitution 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 2d 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.

Origin

This is a copy

92% identical to speckit.constitution — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

Outline

You are updating the project constitution at .specify/memory/constitution.md. This file is a TEMPLATE containing placeholder tokens in square brackets (e.g. [PROJECT_NAME], [PRINCIPLE_1_NAME]). Your job is to (a) collect/derive concrete values, (b) fill the template precisely, and (c) propagate any amendments across dependent artifacts.

Follow this execution flow:

  1. Load the existing constitution template at .specify/memory/constitution.md.

    • Identify every placeholder token of the form [ALL_CAPS_IDENTIFIER]. IMPORTANT: The user might require less or more principles than the ones used in the template. If a number is specified, respect that - follow the general template. You will update the doc accordingly.
  2. Collect/derive values for placeholders:

    • If user input (conversation) supplies a value, use it.
    • Otherwise infer from existing repo context (README, docs, prior constitution versions if embedded).
    • For governance dates: RATIFICATION_DATE is the original adoption date (if unknown ask or mark TODO), LAST_AMENDED_DATE is today if changes are made, otherwise keep previous.
    • CONSTITUTION_VERSION must increment according to semantic versioning rules:
      • MAJOR: Backward incompatible governance/principle removals or redefinitions.
      • MINOR: New principle/section added or materially expanded guidance.
      • PATCH: Clarifications, wording, typo fixes, non-semantic refinements.
    • If version bump type ambiguous, propose reasoning before finalizing.

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.
