forecast

forecast is a skill for Claude Code from EmpiricaAI/empirica. It costs 101 tokens per session (1,306 once invoked), scanned A, original, MIT.

A planning guide for predicting what a project should build or release next and later checking those predictions. It records the expected direction, time frame, evidence, confidence, and what would prove the prediction wrong.

In plain words
What is it for?
Use it when preparing a roadmap, release, or quarter plan, deciding what to do next, or reviewing past predictions.
Why use it?
It turns vague roadmaps into predictions that can be checked against evidence. This helps reveal weak assumptions and whether earlier forecasts were accurate.

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

forecast 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Forecast

Load this when the question is "what comes next", or when a release is about to grade the last forecast.

A direction is a prediction: what will happen, by which release, how sure we are, what that rests on, and what would prove it wrong. In empirica core, README's What's Coming renders docs/ROADMAP.yaml: the schema, the evidence kinds and their confidence caps are in that file's header and scripts/release.py enforces them. Read it, do not restate it here. A project without that file keeps its forecast in its goals; steps 1 to 5 and the gardening apply unchanged, and creating a public roadmap is a question for the human, not a default.

The pass

  1. Gather (noetic). Open goals (goals-list), unknowns, open assumptions, recent mistakes, accepted mailbox items (mailbox poll --status accepted), calibration biases, the reproduced-defect backlog, and the last forecast in docs/ROADMAP.yaml. Count with a command. A figure you typed from memory is not evidence.
  2. Draft candidates. Per candidate: one-sentence prediction with a horizon release, evidence kind, confidence (the kind caps it), a falsifier a stranger can observe, impact (low / medium / high), and steered (is a goal already open for it?).
  3. Sufficiency. A candidate with no measured or reviewed basis is not a direction yet: it becomes a question. So does one whose falsifier you cannot write as the prediction's own sentence (if you cannot, there are two claims). Check each basis against HEAD: a report older than the code is not evidence (git log -S<symbol> --since=<report date> -- <path>).
  4. Ask at most three questions. Rank by impact × (1 − confidence), the answer that would reorder the list most. Each is an AskUserQuestion (or your harness's ask-the-user tool) with your predicted answer first, marked Recommended, and the one reason that grounds it. If you cannot predict the answer you have not read enough. Attention is the scarce resource: one question that changes the ranking beats five that do not.
  5. Route attention.

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.

forecast is a skill published in the GitHub repository EmpiricaAI/empirica (253 stars, last pushed today), licensed MIT. It adds 101 tokens to every session and 1,306 once invoked, about $0.0004 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 2026-10-26.
