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 | $0.00045 | $0.01192 |
| Opus 5 | $0.00023 | $0.00596 |
| Sonnet 5 | $0.00009 | $0.00238 |
| Haiku 4.5 | $0.00005 | $0.00119 |
Grade A, and why
diagnose 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 5d 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 — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<on_start> agentdb recall " <files/symbols>" --global
Recall again after isolation reveals better symbols, when the hypothesis changes,
or when a different failure appears.
</on_start>
<skill_load> Load: skills/debug/SKILL.md, skills/build/reference/testing.md, skills/architecture/SKILL.md </skill_load>
<ask_user>
Use AskUserQuestion when: hypotheses formed and user may have domain knowledge
Ask: "Top hypothesis: {hypothesis}. Does this match what you're seeing, or is there context I'm missing?"
Options: investigate that, I have more context, try a different hypothesis
</ask_user>
</step>
<step id="diagnose">
Identify confirmed root cause.
List affected files and blast radius.
Recommend fix approach (don't implement yet).
Determine tier based on blast radius.
</step>
<step id="handoff">
Output structured diagnosis.
Hand off to /kernel:ingest or /kernel:forge for implementation.
If the user wants to fix immediately, transition to execute mode.

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.

diagnose is a skill published in the GitHub repository ariaxhan/kernel-claude (12 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 1,192 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 2026-08-30.

prolong
Recover and use durable coding-session history from PRO-LONG's local append-only log. Use on long-running coding tasks, after context compaction or session resume, when reconstructing prior decisions or tool results, or before repeating work that may already have been attempted.
lemmalog
Externalize working memory and logical state into the lemmalog Datalog engine (MCP). Use for ANY multi-step task where state should outlive one context window or span agents: long investigations, debugging sessions, audits, multi-agent searches, systematic explorations, planning with many interdependent constraints…
causal-memory
Causal memory for agents — install/setup the causal-memory MCP server, then record decisions/outcomes and recall them before acting. Trigger when the user asks to install or set up causal-memory/agent memory, when causal-memory MCP tools are available and the agent faces a non-trivial decision (architecture, debugging…
