harvest

harvest is a command for Claude Code from vinnie357/claude-skills. It costs 26 tokens per session (747 once invoked), scanned A, original, MIT.

A command that investigates a working prototype and produces implementation-neutral feature specifications and software-development checks.

In plain words
What is it for?
It coordinates inventories of pages, data, integrations, and dependencies; separates product features from prototype shortcuts; assesses licensing and security; and writes markdown reports.
Why use it?
It helps teams understand what a prototype does, which parts represent real product value, and which shortcuts should not be carried forward.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is /pm:harvest ../checkout-prototype --output=docs/specs/.

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.

Security

Grade A, and why

harvest 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 7d 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.

What it actually says

Harvest implementation-agnostic feature specs from a working prototype. Spawns the pm-lead agent, which fans out discovery workers across the prototype's routes/pages, data models, integrations/dependencies/stack, and (when present) a read-only bees map; classifies findings into customer-value features versus prototype shortcuts; runs the SDLC guardrail checklist; and writes markdown spec artifacts.

What it does:

  1. Discoverypm-discovery shards inventory routes/pages, data models, and integrations/deps/stack in parallel, plus a bees map when .bees/ exists in the prototype. Pure inventory, no judgement, every entry cited to a file path.
  2. Separationpm-separator spot-verifies sampled claims, classifies each item as a customer-value feature or a prototype shortcut that must not carry forward (zero/minimal auth, hardcoded data, scale/perf assumptions), and drafts WHAT/WHY value statements that pass the portability test.
  3. SDLC assessmentpm-sdlc-assessor walks the licensing/security/supportability checklist from /pm:spec-harvest's references/sdlc-checklist.md, evidencing every row.
  4. Spec generationpm-spec-writer composes the feature-inventory and SDLC-assessment artifacts, then one pm-prd-author runs per major feature area in grounded mode to produce a PRD.

Artifacts land under <OUTPUT_DIR>/: <DATE>-feature-inventory.md, <DATE>-sdlc-assessment.md, prd/<DATE>-<feature-area>.md per feature area.

Arguments:

  • [path-to-prototype] — absolute or relative path to the prototype repo. When omitted, ask the user where the prototype lives before doing anything else.
  • --output=<dir> — output directory for artifacts. Default docs/pm/ under the prototype root.

Examples:

/pm:harvest ~/github/checkout-prototype
/pm:harvest ../checkout-prototype --output=docs/specs/

Skills the lead loads (no globs — explicit names):

  • /pm:spec-harvest
  • /core:agent-loop
  • /core:anti-fabrication
  • /core:bees
  • /claude-code:claude-teams

Task instructions:

Before spawning anything, ask the operator (unless already answered in the invocation): the intended production audience, any known feature areas to prioritize, and the output directory if not already given via --output. Resolve [path-to-prototype] to an absolute path relative to the current working directory. Verify the path exists (test -d) — if not, stop and report. Probe for <path>/.bees (existence only). Compute DATE as today in YYYY-MM-DD. Resolve OUTPUT_DIR to an absolute path (default <path-to-prototype>/docs/pm/).

Spawn the pm-lead subagent with PROTOTYPE_ROOT=<resolved path>, MODE=harvest, OUTPUT_DIR, DATE, and OPERATOR_ANSWERS set to the clarifying-question responses. Relay the lead's final report to the user, including the artifact paths and the confidence-tag summary.

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.

harvest is a command published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 747 once invoked, about $0.0001 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.
