Getting it into your agent
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.

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 | $0.00459 | $0.00459 |
| Opus 5 | $0.00230 | $0.00230 |
| Sonnet 5 | $0.00092 | $0.00092 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
fli AGENTS.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 3d 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
AGENTS.md
Cursor Cloud specific instructions
Overview
Fli is a Python library providing programmatic access to Google Flights data via reverse-engineered API. It offers a CLI (fli), MCP server (fli-mcp / fli-mcp-http), and Python API. No external services (databases, caches, etc.) are required.
Development commands
All standard commands are in the Makefile and CLAUDE.md. Key ones:
- Install deps:
uv sync --all-extras - Lint:
make lint(ruff) - Format:
make format - Tests:
make test(standard),make test-all(including fuzz) - CLI:
uv run fli flights JFK LAX 2026-05-15 - MCP HTTP server:
uv run fli-mcp-http(serves athttp://127.0.0.1:8000/mcp/)
Testing caveats
- Tests under
tests/search/hit the live Google Flights API and are rate-limited (HTTP 429). These will frequently fail in cloud/CI environments. All other tests (CLI, core, models, MCP) are self-contained and pass reliably. - Run
uv run pytest -vv --ignore=tests/search/to skip flaky API-dependent tests. - One MCP test (
test_search_dates_round_trip) also makes a live API call and may fail with empty results.
Releasing
Releases are manual: GitHub Actions → Release → Run workflow on main,
choose bump=patch|minor|major|explicit. Run with dry_run=true first to
preview. Bump logic is in scripts/bump_version.py (testable). See the
Releasing section in CLAUDE.md and the .github/workflows/release*.yml
workflows for the full process.
MCP server notes
- The MCP HTTP endpoint requires
Accept: application/json, text/event-streamheader. - The
fli/server/module has been removed from the codebase.
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.

fli AGENTS.md is an instructions file published in the GitHub repository punitarani/fli (3,130 stars, last pushed 1mo ago), licensed MIT. It adds 459 tokens to every session, about $0.0023 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.
