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 | $0.00149 | $0.01873 |
| Opus 5 | $0.00075 | $0.00937 |
| Sonnet 5 | $0.00030 | $0.00375 |
| Haiku 4.5 | $0.00015 | $0.00187 |
Grade A, and why
hill-chart 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 8d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hill Chart
Renders what the harness already derives mechanically — never invents a position, never re-runs a computation that would erase true history.
You are not a worker: no WorkOrder, no WorkResult, invoked directly by the user (or by /hill)
exactly like shapeup is. There is nothing to declare in
skills/tech-lead/schemas/domain.schema.json and nothing to teach harness compile or
harness reduce ingest — those steps exist only for dispatched workers.
What you read
Two tiers, per project (kernel/lib/paths.mjs's sharedRoot/localRoot):
- COMMITTED —
shapeup/<slug>/hill/<scope-id>.yml, one file per scope, two fields (scope_id:,phase:), a 4-value enum:UPHILL_UNKNOWN → UPHILL_SOLVED → DOWNHILL_EXECUTION → FINISHED. Written byharness reduce hill. Survives even after a project's local run trace is cleaned up post-ship. - LOCAL —
.shapeup/<slug>/graph.jsonl, the run graph (seekernel/reduce/graph.mjs). Written byharness reduce graph. Supplies everything else: current-round verdict health, gates, orders, rounds, dangling references.
Discovery
Do not readdir either root bare — both hold non-pitch entries (shapeup/knowledge-base/,
.shapeup/metrics/, .shapeup/exports/, .shapeup/pitch-archive/, loose files). A directory
counts as a pitch when:
- Committed:
shapeup/<slug>/containshill/,scopes/, orshaping/. - Local:
.shapeup/<slug>/containsreceipt.json(the mechanical "a run started" fact).
Union the two; track hasCommitted / hasLocal per slug independently. A slug can be
committed-only (shipped, local trace cleaned up), local-only (very early, before scoping), or
both.
Freshness — read this before shelling out
For every slug where hasLocal is true, freshen before reading:
node "${CLAUDE_PLUGIN_ROOT}/kernel/harness.mjs" reduce hill --slug <slug>
node "${CLAUDE_PLUGIN_ROOT}/kernel/harness.mjs" reduce graph --slug <slug>
For a committed-only slug (hasCommitted && !hasLocal), NEVER call reduce hill.
deriveHill() folds whatever T0 verdicts currently exist on disk; a committed-only pitch has
none (the local trace was cleaned up after shipping), so re-running it would silently regress a
true historical FINISHED down to a fabricated UPHILL_SOLVED — reading absence of evidence as
evidence of absence. Read shapeup/<slug>/hill/*.yml for those slugs exactly as committed, and
render them with the archived state the template already implements (see below). Same reasoning
applies to reduce graph — there is no local trace to append from.
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.

hill-chart is a skill published in the GitHub repository nguyenvanphituoc/shapeup-sdlc-plugin (2 stars, last pushed yesterday), licensed MIT. It adds 149 tokens to every session and 1,873 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 2026-08-31.
