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 | $0.00026 | $0.00382 |
| Opus 5 | $0.00013 | $0.00191 |
| Sonnet 5 | $0.00005 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
drift-review 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.
What it actually says
Drift Review — PromptSpeak Governance
You are conducting a behavioral drift review across governed agents.
Workflow
- Get system overview — Call
ps_state_systemto see all agents, their circuit breaker status, and drift metrics. - For each agent with drift above baseline:
- Call
ps_state_drift_historywith the agent ID - Identify the drift trend (increasing, stable, decreasing)
- Note which dimensions are drifting (goal displacement, tool usage patterns, confidence shifts)
- Call
- Present findings as a dashboard:
Agent: [agent_id]
Status: [circuit breaker state]
Drift: [current drift score] (baseline: [baseline])
Trend: [↑ increasing / → stable / ↓ decreasing]
Top concern: [most drifted dimension]
- Recommend actions based on severity:
- Low drift (< 0.3 above baseline): Monitor, no action needed
- Medium drift (0.3–0.7 above baseline): Suggest recalibrating baseline with
ps_state_reset - High drift (> 0.7 above baseline): Recommend halting agent with
ps_state_haltuntil root cause is identified
- If the user wants to act, execute the recommended tools.
Guidelines
- Always show data before recommending actions.
- Drift is not inherently bad — agents learning new tasks will drift. Context matters.
- Check audit logs with
ps_audit_getif the user wants to understand what caused the drift. - A halted agent (circuit breaker open) should be investigated before resuming with
ps_state_resume.
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.

drift-review is a skill published in the GitHub repository chrbailey/promptspeak-mcp-server (1 stars, last pushed 2mo ago), licensed MIT. It adds 26 tokens to every session and 382 once invoked, about $0.0001 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.
