Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is mattv8/ragtime's own configuration. It tells GitHub Copilot how to work on ragtime itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ragtime configures →

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

ragtime debugging.instructions.md scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Debugging

Start With Runtime Health

# API readiness + index loading status
curl -s http://localhost:8000/health | jq .

# Service logs
docker logs -f ragtime-dev
docker logs -f ragtime-db-dev

If /health shows status=initializing, check for startup failures in ragtime/main.py lifecycle (DB connect, rag.initialize(), index recovery/cleanup).

Database Access (Prisma/Postgres)

docker exec -i ragtime-db-dev bash -c \
  'PGPASSWORD="${POSTGRES_PASSWORD}" psql -U "${POSTGRES_USER}" -d "${POSTGRES_DB}" -c "YOUR_QUERY"'

Useful tables: users, sessions, ldap_config, conversations, chat_tasks, index_jobs, index_metadata, index_configs, tool_configs, app_settings.

Prompt debug table (DEBUG mode only): provider_prompt_debug_records.

# Latest prompt-debug rows for one conversation
docker exec -i ragtime-db-dev bash -c \
  'PGPASSWORD="${POSTGRES_PASSWORD}" psql -U "${POSTGRES_USER}" -d "${POSTGRES_DB}" \
   -c "select provider,model,mode,request_kind,created_at from provider_prompt_debug_records where conversation_id = '\''<conversation_id>'\'' order by created_at desc limit 20;"'

# Prompt-debug rows for a specific background task
docker exec -i ragtime-db-dev bash -c \
  'PGPASSWORD="${POSTGRES_PASSWORD}" psql -U "${POSTGRES_USER}" -d "${POSTGRES_DB}" \
   -c "select provider,model,request_kind,created_at from provider_prompt_debug_records where chat_task_id = '\''<task_id>'\'' order by created_at asc;"'

# Compare userspace vs chat prompt payloads (prompt additions + reminders)
docker exec -i ragtime-db-dev bash -c \
  'PGPASSWORD="${POSTGRES_PASSWORD}" psql -U "${POSTGRES_USER}" -d "${POSTGRES_DB}" \
   -c "select mode,left(turn_reminders,120) as reminders,left(prompt_additions,120) as additions,created_at from provider_prompt_debug_records where conversation_id = '\''<conversation_id>'\'' order by created_at desc limit 20;"'

Auth + Session Troubleshooting

# Detect cookie/security config mismatches
curl -s http://localhost:8000/auth/status | jq .

# Login and capture ragtime_session cookie value
TOKEN=$(docker exec ragtime-dev bash -lc 'curl -s -c - -X POST http://localhost:8000/auth/login \
  -H "Content-Type: application/json" \
  -d "{\"username\":\"$LOCAL_ADMIN_USER\",\"password\":\"$LOCAL_ADMIN_PASSWORD\"}" \
  | awk "/ragtime_session/ {print \\$NF}"')

# Authenticated admin endpoint smoke test
curl -s http://localhost:8000/indexes/jobs -H "Cookie: ragtime_session=$TOKEN" | jq .

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.
