Use it when maintaining or extending the project so the assistant can follow its documented rules, consult stored project decisions and bug notes, and run the supplied maintenance checks.

It gives an AI assistant the project’s local knowledge instead of making it guess. This helps avoid issues such as missing database commits, incompatible PHP syntax, unsafe file access, and unconfirmed deletions.

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	$0.00500	$0.00500
Opus 5.5	$0.00200	$0.00200
Sonnet 5.5	$0.00100	$0.00100
Haiku 4.5	$0.00050	$0.00050

Measured 2mo ago against content hash 29746914da2c, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

andy-universal-agent-rules copilot-instructions.md 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.

# 1. Validate index
python .agent/scripts/validate-index.py --report

# 2. Create backup
python .agent/scripts/backup-memory.py

# 3. Update environment
python .agent/scripts/detect-environment.py

# 4. Test search
python .agent/scripts/search-knowledge.py "test" --limit 3

Save from Chat:

# Save gotcha (critical bug/fix)
python .agent/scripts/save-knowledge.py --category gotchas "CRITICAL: [issue + solution]"

# Save pattern (working code pattern)
python .agent/scripts/save-knowledge.py --category patterns "PATTERN: [pattern + usage]"

# Save decision (architecture choice)
python .agent/scripts/save-knowledge.py --category decisions "DECISION: [what + why]"

When to save knowledge:

✅ After solving a tricky bug
✅ After discovering a working pattern
✅ After making an architectural decision
✅ Before ending a productive session

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.
