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 | $0.00040 | $0.01961 |
| Opus 5 | $0.00020 | $0.00981 |
| Sonnet 5 | $0.00008 | $0.00392 |
| Haiku 4.5 | $0.00004 | $0.00196 |
Grade B, and why
toolkit-health scanned grade B with 1 finding 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 yesterday.
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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Overview
hooks/session-analytics.sh persists session stats to .claude/analytics.json. This skill reads that file plus on-disk artifacts (specs, lessons, MTK-related commits) and produces a human-readable health report with anomaly flags and suggested actions. Treat the analytics as an operational pulse, not a formal KPI dashboard: some counters are activity metrics, others are lightweight workflow signals. Read-only — never mutates state.
When To Use
- Engineer asks "how are we using MTK?" / "toolkit health" / "usage stats"
- Periodic team review of adoption (weekly/monthly retro)
- Before promoting a lesson to a CLAUDE.md rule — sanity-check that it reflects real usage
- After a big change to skill routing, to see whether the new routes are firing
When NOT To Use
- As part of a regular build/test loop (this is a diagnostic, not a gate)
- When
.claude/analytics.jsonhas fewer than 3 sessions — not enough data - As a substitute for
/mtk status/ context-report (that skill reports current config, this skill reports historical usage)
Workflow
- Load the data sources in parallel (independent reads — see
docs/parallelism-patterns.md):.claude/analytics.json(session counts, ops, mods, specs_created, lessons_captured, scope_guard_warnings, benchmarks_run, benchmark_last_score)tasks/lessons.mdif present (count^##entries)docs/specs/anddocs/plans/directory listingsgit log --since="30 days ago" --oneline --grep='mtk\|MTK\|toolkit'for MTK-related commits
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.

toolkit-health is a skill published in the GitHub repository moberghr/mtk-agent-toolkit (7 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 1,961 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
