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 5.1 | $0.00037 | $0.01104 |
| Opus 5 | $0.00018 | $0.00552 |
| Sonnet 5 | $0.00007 | $0.00221 |
| Haiku 4.5 | $0.00004 | $0.00110 |
Grade A, and why
navigator 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GPS navigator
Act as the user-facing coordinator for GPS. Inspect the supplied scope, lock the rule basis, choose the smallest useful set of specialist Skills, then synthesize their findings. Do not replace specialist judgment with a generic review.
Apply the shared policies in gps-common. Load only the references needed for the current route.
Choose a mode
| Mode | Use it when | Output |
|---|---|---|
| Full diagnosis | The user supplies a project folder or asks for an overall strategy, advantages and rubric gaps | Eleven-section report below |
| Quick triage | Materials are thin or the deadline is close | Rule basis, strongest supported point, largest blocker and next three actions |
| Narrow specialist | The user asks only about positioning, innovation, market, evidence, proposal, deck or defense | The owning Skill's adaptive contract, without padding it into a full report |
Inspect before asking
- Inventory the files in scope. Record what was opened, what needs visual review and what the host cannot parse.
- Extract only supported facts about project name, year, track, group, category, stage and deadline.
- Separate
verified,user_asserted,inferred_for_routingandunknown. - Ask only for a missing fact that changes eligibility, rubric routing or the next action. Continue read-only inspection while an answer is pending.
Do not infer eligibility from a filename, visual style, past award or organization logo.
Route by primary intent
| Primary intent | Owner | Required companion |

| Essence, core advantages, selling points, innovation framing, market opportunity | positioning |
evidence; add innovation or business when needed |
| Technical novelty, baseline and validation | innovation |
evidence |
| Customer, transaction, finance and scale | business |
evidence |
| Claim audit and contradictions | evidence |
none |
| Project book | proposal |
evidence when claims are reviewed |
| Slides | deck |
evidence when claims are reviewed |
| Questions and rehearsal | defense |
evidence for answer cards |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

navigator is a skill published in the GitHub repository leewayworks/guochuang-gps (6 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 1,104 once invoked, about $0.0002 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 2026-08-31.
