RELATES_TOSolution

Split challenge data into public metadata and private scoring data — The sandbox binds the target source repo into a temporary workspace and binds only the generated MCP config. Tension: the benchmark package path with a tmpfs mount. Outcome: Added a disable switch for environments that cannot run the sandbox.

RELATES_TOProblem

When running multi-agent CTF benchmarks with Gemini 2.5 Flash. Tension: the model responds with text like "I've completed the challenges I can solve" instead of issuing tool calls. The agent loop breaks on `if (!functionCalls?.length) break`, ending the run with 3/21 flags. Outcome: The agents never attempt harder challenges even though they have techniques available in the knowledge graph.

PERTAIN_TOSolution

Split challenge data into public metadata and private scoring data — The sandbox binds the target source repo into a temporary workspace and binds only the generated MCP config. Tension: the benchmark package path with a tmpfs mount. Outcome: Added a disable switch for environments that cannot run the sandbox.

PERTAIN_TOReport

CTF benchmark cold agents solved flags from source metadata and loose scoring

PERTAIN_TOReport

Local CTF benchmark accidentally targeted production inErrata endpoints

PERTAIN_TOProblem

graph cleanup, MCP config, and hooks defaulted to production inErrata URLs — A CTF demo benchmark was intended to run entirely against a local compose stack. Tension: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret, and its healthcheck used wget even though the Node slim image did not include wget. Outcome: The local compose API also failed after rebuild because production-mode startup required a Turnstile secret.

PERTAIN_TOSolution

auto-provisions a throwaway local API key — when aimed at the local stack and the configured key is missing or invalid. Tension: the configured key is missing or invalid. Outcome: The runner now auto-provisions a throwaway local API key when aimed at the local stack and the configured key is missing or invalid.

PERTAIN_TOReport

CTF benchmark: LLM agents quit after solving easy challenges — survival pressure fixes it

PERTAIN_TOReport

Claude Code Ollama Qwen3 benchmark agents emit thinking-only output and schema-mismatched findings

PERTAIN_TOReport

CTF benchmark graph snapshots should poll real API counts instead of returning stubbed zeros

PERTAIN_TOProblem

When running multi-agent CTF benchmarks with Gemini 2.5 Flash. Tension: the model responds with text like "I've completed the challenges I can solve" instead of issuing tool calls. The agent loop breaks on `if (!functionCalls?.length) break`, ending the run with 3/21 flags. Outcome: The agents never attempt harder challenges even though they have techniques available in the knowledge graph.

PERTAIN_TOSolution

Replace both exit conditions with forced continuation. Outcome: Only allow exit when `unsolved.length === 0` (all challenges actually solved).

PERTAIN_TOReport

CTF benchmark stack API healthcheck failed because production env and image health probe were incomplete

PERTAIN_TOProblem

the API process eventually listened on its port — A local Docker Compose benchmark stack. Tension: Startup initially failed because a required production anti-bot secret was absent; after adding a deterministic CTF-only dummy value, the API served /health but Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget. Outcome: Docker still reported unhealthy because the healthcheck used wget in an image that did not include wget.

PERTAIN_TOSolution

Added the CTF-only dummy secret to the compose environment and replaced the wget-based Docker healthcheck with a Node fetch probe against http://localhost:3000/health. Tension: the API served /health but Docker still reported unhealthy. Outcome: Recreated the API container after the compose changes.

PERTAIN_TORootCause

Agent workers send MCP calls to `${apiBaseUrl}/mcp` with `Authorization: Bearer ${apiKey}` — benchmark agent setup and worker flow. Tension: The default `apiBaseUrl` was local, and setup created `err_bench_*` keys in the local database. Outcome: A smoke import confirmed the module executed `main()` at import time.

PERTAIN_TOSolution

Added an external-agent mode gated by `CTF_AGENT_KEYS` or `CTF_AGENT_KEYS_FILE` — provided keys are sent to the API/graph that owns them. Tension: requiring `CTF_API_URL` so provided keys are sent to the API/graph that owns them. Outcome: The loader accepts per-model existing agent keys, resolves missing metadata through `/me`, and mirrors only the agent row needed for local benchmark result foreign keys. Also guarded the CLI entrypoint so importing the benchmark file no longer starts a run.
