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 | $0.00152 | $0.05357 |
| Opus 5 | $0.00076 | $0.02678 |
| Sonnet 5 | $0.00030 | $0.01071 |
| Haiku 4.5 | $0.00015 | $0.00536 |
Grade A, and why
architectural-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Context
- git installed: !
which git 2>/dev/null || echo "not installed" - CLAUDE.md: !
find . -maxdepth 1 -name "CLAUDE.md" -type f - project-discovery.md: !
find . -maxdepth 3 -name "project-discovery.md" -type f - personal config directory: !
bash "${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.
Operating Principles
Read these before dispatching anything. They constrain every step below.
- A focus area is required. This skill analyzes a specific module, directory, or feature. "Analyze the whole codebase" is not a valid input. If no focus area resolves to real files, stop and ask the user to name one.
- The agents own the judgment; the skill orchestrates. The skill validates the focus area, classifies size, selects the roster, fans agents out and in, and renders the report. It does not produce findings itself.
- The discovery roster is signal-selected; the synthesis spine always runs.
han-core:structural-analyst,han-core:behavioral-analyst,han-core:risk-analyst, andhan-core:software-architectrun at every size BECAUSE structure, runtime behavior, risk-of-inaction, and SOLID synthesis are the irreducible core of an architectural read. Every other specialist is added only when the focus area's signals warrant it and the size band allows it, BECAUSE dispatching an agent whose domain the code does not touch burns tokens and dilutes the report with low-signal findings. - Default to small. Start classification at small and escalate only when a higher-band signal is clearly present. Borderline signals stay at the smaller band. Under-dispatching is recoverable by re-running at a larger size; over-dispatching is not.
- Recommendations, not refactors. The skill never modifies code.
han-core:software-architect(andhan-core:system-architectwhen dispatched) produce pseudocode sketches for proposed boundaries. Implementation is a separate, later step. - Negative results are valuable. When a dimension is genuinely clean (no concurrency in a pure-functional module, sound boundaries), the report says so. Agents must not fabricate findings to fill a section.
- Single pass, no iteration round. This skill is a fan-out / fan-in, not an iterative loop. If a band proves too small, the user re-runs at a larger size — the skill does not self-escalate mid-run.
- System-altitude work is deferred by default.
han-core:software-architectdefers cross-service / bounded-context / trust-boundary findings rather than absorbing them.han-core:system-architectis added to the roster only at large size and only when a boundary-crossing seam is actually present. When it is not dispatched, those deferrals are surfaced in the report so the user can dispatchhan-core:system-architectseparately. - The report template lives at references/architectural-analysis-report-template.md. The skill renders that template by filling placeholders and removing the sections whose agent was not dispatched. It does not invent a structure inline.
- The synthesized report is written for a named reader. As the skill writes the final report's synthesized prose, it
sources the shared standard by invoking
han-communication:readability-guidanceand applies it, holding one audience above the writing: the engineer weighing the module's design and deciding whether to change it. Scope that frame per section so the technical specifics that reader needs — file paths, finding IDs, exact conditions, pseudocode — are preserved, never simplified away.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

architectural-analysis is a skill published in the GitHub repository testdouble/han (247 stars, last pushed 4d ago), licensed MIT. It adds 152 tokens to every session and 5,357 once invoked, about $0.0008 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.
