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 | $0.01108 |
| Opus 5 | $0.00000 | $0.00554 |
| Sonnet 5 | $0.00000 | $0.00222 |
| Haiku 4.5 | $0.00000 | $0.00111 |
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.
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:
-
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.
- Identify every placeholder token of the form
-
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_DATEis the original adoption date (if unknown ask or mark TODO),LAST_AMENDED_DATEis today if changes are made, otherwise keep previous. CONSTITUTION_VERSIONmust 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.

speckit.constitution is a command published in the GitHub repository bl1nk-bot/agent-library (2 stars, last pushed 2d ago), licensed CC0-1.0. It costs nothing until one of its globs matches a file; then it loads 1,108 tokens. A static security scan graded it A with 0 findings. It is 92% identical to speckit.constitution, differing in 4 lines, and is treated as a copy.
