Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00031 | $0.00329 |
| Opus 5 | $0.00015 | $0.00164 |
| Sonnet 5 | $0.00006 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
praxis-architect 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 10d 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.

Praxis Architect
Run Phase B: architecture and sign-off preparation.
- Verify
requirements_freezehas cleared or ask the user to approve the evidence pack. - Select the applicable workflow from
workflows/based on the charter. - Create architecture decisions, ADRs, C4 diagrams, threat model, implementation constraints, and phased roadmap.
- Spawn or use the
architecture-challengersubagent if installed; otherwise run the Challenger role fromagents/architecture-challenger.md. - Resolve Challenger findings by revising the design or recording override rationale.
- Assemble the
architecture_sign_offevidence pack from governance. - Stop for user approval before implementation.
Do not begin implementation slices before architecture sign-off.
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.

praxis-architect is a skill published in the GitHub repository jeet129/praxis (7 stars, last pushed 6d ago), licensed MIT. It adds 31 tokens to every session and 329 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
