Use it to design routes, validate API data with Pydantic, manage dependencies and middleware, generate API documentation, handle asynchronous work, and test services.
Why use it?
It helps explain how FastAPI features fit together and diagnose common design or implementation problems.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 .claude/scripts/skill-search.py --query "[detected platform]".

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

dynamic-specialist 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.

Dynamic Specialist — On-Demand Expert Generator

Role: Cover any platform Raven has no curated skill for. Memory: Reads security_log.md before every answer. Writes after every answer. Promotion: Flags platform for curated skill after 3 confirmed uses.


Full Agent Chain

Step 0 → check domain packs       packs/ directory — curated Tier 2a knowledge
Step 1 → skill-search.py          check for existing curated skill
Step 2 → read security_log.md     load prior observations for this platform
Step 3 → read cache               load cached profile if it exists
Step 4 → assess confidence        HIGH / MEDIUM / VERIFY
Step 5 → search agent             ONLY if MEDIUM or VERIFY
Step 6 → construct profile        log + cache + search + tools-landscape + pack
Step 7 → deliver answer           full specialist format
Step 8 → update log + cache       append findings, increment usage count
Step 9 → check promotion          flag if count >= 3

Step 0 — Check Domain Packs (Tier 2a)

Check: skills/dynamic-specialist/packs/
Look for: JSON pack matching detected domain or tool category

If pack found:
  → Load pack JSON (1-2K tokens)
  → Use tools[].description, gotchas, decision_matrix for context
  → Skip search agent (Step 5) unless user asks about 'latest'
  → Pack is curated knowledge — higher trust than search results

If no pack found:
  → Proceed to Step 1 (normal dynamic flow)

Pack format: see packs/README.md

Step 1 — Skill Lookup First

Before doing anything, run:

python3 .claude/scripts/skill-search.py --query "[detected platform]"

If a curated skill is found → hand off immediately. Do not proceed with dynamic generation. Curated skills always beat dynamic. Dynamic is the fallback only.


Step 2 — Read the Log

Read: docs/observations/security_log.md
Filter: entries where Platform = [detected platform]

If entries found:
  → Extract: known gotchas, confirmed patterns, expert used, search results
  → Load as context before constructing profile

If no entries:
  → Cold start — rely on search + built-in knowledge

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.
