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 | $0.00140 | $0.05412 |
| Opus 5 | $0.00070 | $0.02706 |
| Sonnet 5 | $0.00028 | $0.01082 |
| Haiku 4.5 | $0.00014 | $0.00541 |
Grade A, and why
plan-work-items scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Context
- CLAUDE.md: !
find . -maxdepth 1 -name "CLAUDE.md" -type f - project-discovery.md: !
find . -maxdepth 3 -name "project-discovery.md" -type f - feature-implementation-plan.md: !
find . -maxdepth 5 -name "feature-implementation-plan.md" -type f - personal config directory: !
bash "${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.
Plan Work Items
Break an implementation plan into vertical slices (tracer bullets) and write them as work items to a single
work-items.md file.
This skill mostly coordinates: reading the boundary this work descends from, locating the plan or context, resolving where the file goes, printing the breakdown, writing the work-items file. It runs autonomously apart from two named turns: the confirmation turn it takes when no boundary record exists, and the single stop for an input only the user can supply. Step 5 is where the judgement comes into play, in dividing up the plan.
Operating Principles
- Run autonomously, with two named exceptions. After the initial request, run end to end without pausing for human
confirmation. When a decision has a reasonable default (where the file goes, how the plan divides), make it, state it,
and proceed. Print the work item breakdown for visibility, but never gate on approval to continue. Two situations are
exceptions, and they are the only ones:
- The confirmation turn, taken when no boundary record exists, per Step 0.
- The single stop, taken once when an input only the user can supply is missing and its absence degrades the work items, per operator-escalation-rule.md.
What ships with it
4 files 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.

plan-work-items is a skill published in the GitHub repository testdouble/han (256 stars, last pushed 5d ago), licensed MIT. It adds 140 tokens to every session and 5,412 once invoked, about $0.0007 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 2026-09-03.
Other skills, from other repositories
work
Execute Elixir/Phoenix plan tasks with progress tracking. Use after /phx:plan to implement features with mix compile and mix test verification after each step, or --continue to resume interrupted work.
catchup
Summarize and review what changed while you were away. Use after a weekend, vacation, or flight to check missed PRs, git commits, Linear tickets, and meetings — one prioritized brief, not a firehose.
plan
Plan features spanning multiple domains: billing (Stripe), auth (RBAC), real-time (Presence), webhooks, jobs (Oban). Use when designing interconnected systems or converting review findings into tasks.
phx-deps-update
Bump outdated Hex deps — inventory, snapshot changelogs, update, fix breaks, split reviewable PRs (patches bundled, majors solo). Use to upgrade/bump Elixir dependencies or when versions fall behind. NOT for deps.get failures (phx-investigate).

Owns execution: how work actually gets done across the organization, including process, program management, capacity, vendors, supply chain, and service delivery. Use this when execution is the problem rather than strategy, to design or fix a process, to resolve cross-functional handoff failures, to plan capacity, to…

Runs the ongoing relationship with accounts after the sale — segmenting coverage against account value, building a health score that predicts rather than describes, running reviews customers find worth attending, forecasting renewals honestly, and finding expansion that follows usage instead of quota.
