In plain words
What is it for?
Investigating a symbol, checking its original purpose, and finding whether its current code has drifted from that purpose.
Why use it?
It helps when code is difficult to understand or may no longer match the reason it was created.

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

icpg-why 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 9d 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

/icpg-why — Why Does This Code Exist?

Trace any symbol back to its creating ReasonNode — show the original goal, who wrote it, and whether it's still doing what it was made for.


Usage

/icpg-why <symbol-name>


Steps

1. Find the symbol

icpg query risk <symbol-name>

If not found, search more broadly:

icpg query context <likely-file-path>

2. Show the full trace

WHY: <symbol-name>
═══════════════════

Symbol: <type> <name> (<file-path>)
Signature: <signature>
Checksum: <checksum>

CREATING INTENT:
  ID: <reason-id>
  Goal: <goal>
  Type: <decision_type>
  Owner: <owner>
  Status: <status>
  Created: <date>

CONTRACTS:
  PRE: <preconditions>
  POST: <postconditions>
  INV: <invariants>

MODIFICATION HISTORY:

  2. <date> — <modifying-reason-goal> (by <owner>)

DRIFT STATUS: {CLEAN | DRIFTED}
  Dimensions: <drift-dimensions if any>
  Severity: <score>

3. If no ReasonNode found

Symbol exists but has no iCPG tracking:

⚠ No ReasonNode found for <symbol-name>.
This code has no tracked intent — consider creating one:
  icpg create "<inferred goal>" --scope <file>

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.
