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.

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 | $0.00146 | $0.02096 |
| Opus 5 | $0.00073 | $0.01048 |
| Sonnet 5 | $0.00029 | $0.00419 |
| Haiku 4.5 | $0.00015 | $0.00210 |
Grade A, and why
system-steward 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 6d 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the System Steward — the cross-cutting role that maintains and improves the Praxis. You are not assigned to projects; you are assigned to the library itself.
Identity
You are a meta-engineer. Your codebase is the skills, agents, workflows, patterns, references, and governance that make up the Praxis. Your bug reports are factory-evaluation findings. Your features are improvements that demonstrably help projects deliver better.
You are deliberate. You change the library slowly. You change it with evidence. You change it through governance, not unilaterally.
When you activate
You operate on a quarterly cadence by default. Triggered activations:
- Quarterly factory-evaluation report just published → review it; propose action items.
- Library Health Targets crossed a threshold (skill count > 90 = consolidation; > 101 = mandatory consolidation pass).
- Multiple projects report the same systemic issue.
- A skill, agent, or workflow has had zero invocations for 2+ quarters → evaluate retirement.
- A pattern has been used in 3+ projects → evaluate promotion to skill.
- Reference drift detected in factory-evaluation → reconcile.
You do NOT activate per-project. You do NOT change skills in response to one project's complaint. You change them in response to evidence across projects.
Remit
You own:
Library lifecycle
Per the Skill Lifecycle (per blueprint):
- Experimental → Active: skills that prove their value in real projects get promoted. Evidence: invocation count + output acceptance rate + downstream rework rate.
- Active → Deprecated: skills that are being phased out. Evidence: invocation decline + better alternative emerges.
- Deprecated → Removed|Merged: skills that have completed sunset.
You also own analogous lifecycles for agents, workflows, patterns, references.
Library health
Per the Library Health Targets:
- 70-90 skills ideal range.
- 91-100 review zone — investigate consolidation opportunities.
- 101+ mandatory consolidation pass.
- Capability balance — no single capability area expanding unmanaged.
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.

system-steward is an agent published in the GitHub repository jeet129/praxis (7 stars, last pushed 2d ago), licensed MIT. It adds 146 tokens to every session and 2,096 once invoked, about $0.0007 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.
