What is workplan-builder?

A guide for turning a hypothesis tree—a structured set of questions about an analysis—into an executable workplan. It assigns analysis methods, data sources, owners, timelines, and expected conclusions, while marking unknowns.

Use it to create workplan tables, attach responsibilities and timing to each hypothesis, identify missing inputs, and check whether the effort matches the expected value.

It makes analytical work actionable without silently inventing owners, deadlines, or data sources.

Token cost

What it costs to keep this loaded

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	$0.00062	$0.00677
Opus 5.5	$0.00025	$0.00271
Sonnet 5.5	$0.00012	$0.00135
Haiku 4.5	$0.00006	$0.00068

Security

Grade A, and why

workplan-builder 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 2mo 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.

Workplan Builder

When to use

Translate hypothesis tree into executable workplan with owners, timelines, data sources, pre-stated so-whats.

What this skill does not do

Does not build hypothesis tree — route to hypothesis-tree if missing.
Does not assign owners without confirmation — flag TBD.
Does not invent data sources — flag unknown.

Preconditions

Input	If missing
Hypothesis tree	Ask to run `hypothesis-tree` or supply structure
Owner/timeline constraints	Ask; no arbitrary day counts

Provisional mode

Missing owners/timelines: table with TBD flags; no silent placeholders.

Trust spine

Confidence bands (structured-aggregation): High = all rows complete; Medium = some TBD; Low = tree missing branches.
Escalation: Disproportionate effort vs so-what → flag revisit tree.

Workflow

Get hypothesis tree.
Per sub-hypothesis: analysis method, data source, owner, timeline, expected so-what (from tree).
Sanity-check effort vs payoff.
Output table; flag incomplete rows.

Output format

Hypothesis	Analysis	Data source	Owner	Timeline	Expected so-what
...	...	...	...	...	...

Flags: effort/payoff mismatches; missing owner/timeline/source.

Worked example

Input: Tree branch "elasticity >15% in mid-tier."

Row: Cohort price-volume analysis | billing warehouse | TBD owner | before steering 3/15 | if true, supports revert recommendation.

Quality checks before delivering

So-what carried from tree pre-analysis
No invented sources or owners
Effort flags applied

Propose profile update

When a stable convention surfaces during this run (thresholds, naming, tone, output format, or recurring corrections), propose a profile update: show the exact diff against ~/.claude/plugins/config/claude-for-strategy/consulting/CLAUDE.md (org-wide facts go to org-profile.md), ask for confirmation, and write only on yes. Only /consulting:practice-setup auto-applies a full profile write.

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.

workplan-builder is a skill published in the GitHub repository daddia/claude-for-strategy (2 stars, last pushed 4mo ago), licensed MIT. It adds 62 tokens to every session and 677 once invoked, about $0.0002 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 2026-08-31.

Test-driven development, from unit to end-to-end tests. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration or end-to-end tests (Playwright, Cypress). Don't use to backfill tests on existing code (/refactor) or diagnose an unknown bug (/debug).
