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 | $0.00000 | $0.01332 |
| Opus 5 | $0.00000 | $0.00666 |
| Sonnet 5 | $0.00000 | $0.00266 |
| Haiku 4.5 | $0.00000 | $0.00133 |
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 9d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
description: Create or amend the project constitution handoffs:

- label: Review Architecture agent: speckit.plan prompt: Review architecture alignment with constitution
User Input
$ARGUMENTS
You MUST consider the user input before proceeding (if not empty).
Outline
The constitution is the governing document for the project. It defines core principles, development workflow, and governance rules that all agents and engineers must follow. It lives at docs/plans/CONSTITUTION.md and is symlinked from .specify/memory/constitution.md.
Step 1: Determine Mode
Check whether docs/plans/CONSTITUTION.md exists:
- If it does NOT exist → Create mode (go to Step 2)
- If it exists → Amend mode (go to Step 3)
If the user input is empty:
- In create mode: ask the user to describe the project's purpose, core values, and any non-negotiable constraints
- In amend mode: ask the user what they want to change and why
Step 2: Create New Constitution
-
Load the template from
templates/constitution-template.mdto understand the required structure and sections. -
Gather project context:
- Read
README.md(if it exists) for project purpose and scope - Read
docs/plans/ARCHITECTURE.md(if it exists) for technical context - Use the user's input for principles and values
- Read
-
Fill the template by replacing all
[PLACEHOLDER]tokens with concrete content derived from the project context and user input:- Replace
[PROJECT_NAME]with the actual project name - Replace each
[PRINCIPLE_N_NAME]and[PRINCIPLE_N_DESCRIPTION]with real principles - Add or remove principle sections as needed (the template shows 5 examples but the actual count depends on the project)
- Replace
[SECTION_2_NAME],[SECTION_3_NAME]and their content with appropriate sections for the project - Fill
[GOVERNANCE_RULES]with concrete governance rules - Set
[CONSTITUTION_VERSION]to0.0.1,[RATIFICATION_DATE]and[LAST_AMENDED_DATE]to today's date
- Replace
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.

speckit.constitution is a skill published in the GitHub repository caipe-io/ai-platform-engineering (407 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,332 tokens. 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 2026-08-30.
