What is constitution?

A command for creating or updating a project's constitution, meaning the document that records its development principles and rules.

Loading the existing constitution, filling its placeholders from user input or project context, and propagating amendments to dependent project artifacts.

It keeps the project's guiding principles concrete and updates related templates when those principles change.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00021	$0.01129
Opus 5.5	$0.00008	$0.00452
Sonnet 5.5	$0.00004	$0.00226
Haiku 4.5	$0.00002	$0.00113

Security

Grade A, and why

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 1mo 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.

User Input

$ARGUMENTS

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

Outline

You are updating the project constitution (via the akka_sdd_constitution MCP tool). 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.

Note: If the project constitution does not exist yet, it should have been initialized from .akka/templates/constitution-template.md during project setup. If it's missing, copy the template first.

Follow this execution flow:

Load the existing constitution at the project constitution (via akka_sdd_constitution).
- 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.
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.
Draft the updated constitution content:
- Replace every placeholder with concrete text (no bracketed tokens left except intentionally retained template slots that the project has chosen not to define yet—explicitly justify any left).
- Preserve heading hierarchy and comments can be removed once replaced unless they still add clarifying guidance.
- Ensure each Principle section: succinct name line, paragraph (or bullet list) capturing non‑negotiable rules, explicit rationale if not obvious.
- Ensure Governance section lists amendment procedure, versioning policy, and compliance review expectations.

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.
