Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00160 | $0.00838 |
| Opus 5.5 | $0.00064 | $0.00335 |
| Sonnet 5.5 | $0.00032 | $0.00168 |
| Haiku 4.5 | $0.00016 | $0.00084 |
Grade A, and why
explanation-guidance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Context
- personal config directory: !
bash "${CLAUDE_PLUGIN_ROOT}/scripts/han-config-dir.sh" 2>/dev/null || echo "$HOME/.claude" - project .han/config.md: !
cat .han/config.md 2>/dev/null || echo ""
As your first action, use the Read tool on .han/config.md inside the personal config directory path above. A read
that returns no file is no personal configuration: continue silently. When that file or the project .han/config.md
probe supplies content, apply it per config-rule.md, which governs precedence
between the two files, relative-path resolution, and what to do with a file that reads but cannot be used.
Explanation Guidance
You have invoked explanation-guidance to source the shared explanation standard before you talk to a person. This skill
surfaces the standard into your own context and hands control back. It is a means to writing your turn, not the turn
itself: apply what it surfaces, then RETURN to the workflow that called you and finish it.
This skill is inline — it runs in your context, not an isolated one, so the standard it surfaces stays available to you after it returns. Do not treat anything here as a stopping point or a final answer.
When this standard applies
It applies to what you say to a person in a turn: an escalation, an opening confirmation turn, a stop for a missing input, or any explanation of a technical consequence to someone who will not implement the work.
It does not apply to the written deliverable you are producing. That is governed by the readability standard, which you
source through han-communication:readability-guidance. A run often needs both, at different moments.
Step 1: Read the standard
Read ${CLAUDE_PLUGIN_ROOT}/references/explanation-rule.md so its full content enters your context. It carries the
concrete-outcome requirement, the four-part form for a question shaped like data entry, the unintroduced-term test, and
the rule that the consequence comes before the technical detail.
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.

explanation-guidance is a skill published in the GitHub repository testdouble/han (304 stars, last pushed today), licensed MIT. It adds 160 tokens to every session and 838 once invoked, about $0.0006 per session on Opus 5.5. 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.
