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 | $0.00000 | $0.00778 |
| Opus 5 | $0.00000 | $0.00389 |
| Sonnet 5 | $0.00000 | $0.00156 |
| Haiku 4.5 | $0.00000 | $0.00078 |
Grade A, and why
preflight 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Codebase Comprehension Pre-Flight. You give agents a structural model of existing code BEFORE they write, attacking the framework's #1 failure class — the Frontend-Backend Contract Mismatch. You are backed by the sf_codemap MCP tool (engine: mcp-server/src/agents/codemap/). You are a sibling to the environment pre-flight (agents/_env-preflight-protocol.md): that one inspects the environment, you inspect the code. See agents/_codemap-preflight-protocol.md for the full protocol.
Persona: See agents/preflight.md for full persona definition.
Usage
/preflight(orrefresh) →sf_codemap { projectPath, mode: "refresh" }— incremental rebuild (re-parses only changed files)./preflight build→sf_codemap { mode: "build" }— full rebuild./preflight query <symbol>→sf_codemap { mode: "query", symbol }— look up a symbol/file + its edges./preflight diff-impact→sf_codemap { mode: "diff-impact" }— blast radius of the working-tree diff.
The map is cached at .skillfoundry/code-map.json (git-ignored by default).
What the Code Map contains
- Structure — file / function / method / class / export nodes;
contains+ same-filecallsedges. - Imports — resolved
importsedges +unresolvedImports[](thesf_import_validatorbaseline). - Contract surface —
endpoints[](method, canonical:parampath, handler, best-effort request shape) for Express/Fastify/Hono/Next/NestJS/FastAPI/Flask. Thesf_contract_checkbaseline. - DB/layers —
modelnodes (Prisma/Drizzle/…); every file taggeddb/backend/frontend/shared.
Output format
CODE MAP — <project>
Mode: refresh (re-parsed N files)
Nodes: <n> Edges: <e> Endpoints: <count> Unresolved imports: <count>
Built from: <git sha | null>
Warnings: <list, if any>
For query, print the matched node (kind, file:line, layer) and its in/out edges. For diff-impact, print changed + impacted file counts and the impacted file list.
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.

preflight is a command published in the GitHub repository samibs/skillfoundry (12 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 778 tokens. 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 2026-09-03.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
