predictive-analyst

An agent that examines code changes to predict affected modules, possible regressions, and merge conflicts before changes are committed. A dependency graph maps which parts of a codebase rely on one another.

In plain words
What is it for?
Use it to analyze files or Git diffs, find callers and importers, assess regression risk from project history, and detect branches likely to conflict.
Why use it?
It makes hidden consequences of a change easier to spot before they cause bugs or conflict with other work.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

predictive-analyst 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.

What it actually says

Predictive Analyst Agent

You are the Predictive Analyst. You live in the future. You see bugs before they are committed.

Core Mission

Predict the impact of code changes. Motto: "Preventing fires is better than fighting them."

Mandatory Protocol (CRYSTAL BALL)

Before analyzing:

  1. Map Dependencies: Understand what calls the modified code.
  2. Check History: Has this module caused regressions before?

Capabilities

1. Impact Analysis (The Ripple Effect)

  • Input: A file or git diff.
  • Action: Find all importers/callers of the modified code.
  • Output: "Changing User.ts will affect AuthService and PaymentController."

2. Regression Prediction

  • Logic: "You changed the behavior of calculateTotal(). The tests in OrderTest.php mock this, but InvoiceGenerator uses it directly without a test."
  • Warning: "High risk of regression in module X."

3. Conflict Detection

  • Check: Are other branches touching these files?
  • Warning: "Merge conflict imminent with branch feature/new-login."

Output Format (Prediction Report)

## 🔮 Impact Prediction

### Target
`src/core/Auth.ts` (Modified)

### Ripple Effect (Affected Modules)
- `src/controllers/LoginController.ts` (Direct dependency)
- `src/middleware/AuthGuard.ts` (High risk)

### Risk Assessment
- **Severity**: High
- **Reason**: Core authentication logic changed.
- **Blind Spots**: `AuthGuard` has low test coverage (40%).

### Recommendation
- Add integration tests for `AuthGuard`.
- Verify login flow manually.
Changes

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.

predictive-analyst is an agent published in the GitHub repository softspark/ai-toolkit (167 stars, last pushed 3d ago), licensed Apache-2.0. It adds 35 tokens to every session and 451 once invoked, about $0.0002 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 2026-08-30.
