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 | $0.00042 | $0.00515 |
| Opus 5 | $0.00021 | $0.00258 |
| Sonnet 5 | $0.00008 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
kairos-chain 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 12d 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.

KairosChain — Self-Amendment MCP Server Framework
KairosChain provides a layered skill architecture (L0/L1/L2) with blockchain-backed auditability. All core functionality is provided via MCP tools. This skill provides an architectural overview and guides you to per-SkillSet skills for detailed workflows.
Three-Layer Architecture
L0 — Constitution (Self-Referential)
Immutable safety rules and meta-governance. L0 defines the rules that govern L0 itself — this structural self-referentiality is the foundation of KairosChain's design. Changes require human approval and full blockchain recording.
L1 — Knowledge
Project knowledge in structured format. Changes recorded with hash references.
Use knowledge_list and knowledge_get to browse, skills_promote to promote from L2.
L2 — Context
Temporary session context. Free modification, no blockchain recording.
Use context_save for session work, promote to L1 when proven valuable.
Key Principle: Layer Governance
L2 (free) → skills_promote → L1 (recorded) → skills_promote → L0 (human approval + blockchain)
Each layer has increasing governance requirements. This gradient ensures that volatile ideas can be captured freely (L2) while stable knowledge is protected (L0).
Per-SkillSet Skills
Detailed workflow guides are provided by individual SkillSets:
- agent — Cognitive OODA loop with autonomous mode
- skillset_exchange — P2P SkillSet exchange via Meeting Place
- skillset_creator — Scaffold and design new SkillSets
- plugin_projector — Manage Claude Code plugin projection
- kairos-knowledge — Browse available L1 knowledge (auto-generated)
Use tool_guide for dynamic tool discovery and workflow recommendations.
When MCP Is Not Connected
If the MCP server is not running, these skills and agents are still visible but MCP tools will not be available. To connect:
- Ensure
gem install kairos-chainis installed (Ruby 3.0+ required) - Check
.mcp.jsonconfiguration in the project root - Restart Claude Code or run
/reload-plugins
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.
- 12d ago First seen · 57 lines · 42 tokens per session scan A a4734cc15596
kairos-chain is a skill published in the GitHub repository masaomi/KairosChain_2026 (7 stars, last pushed yesterday), licensed MIT. It adds 42 tokens to every session and 515 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.
