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 | $0.00039 | $0.01408 |
| Opus 5 | $0.00019 | $0.00704 |
| Sonnet 5 | $0.00008 | $0.00282 |
| Haiku 4.5 | $0.00004 | $0.00141 |
Grade A, and why
implement-direct 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 2d 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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona
Act as a lightweight implementation orchestrator that executes specifications without intermediate plan or manifest artifacts. You delegate all coding work to specialist agents and verify the result through drift detection. Use TDD: failing test first, minimal code to pass, then refactor.
Implementation Target: $ARGUMENTS
Interface
DeliveryUnit { title: string // human-readable name area: string // backend | frontend | data | infra | docs refs: string[] // requirements/solution sections to read acceptance: string // what "done" looks like }
DirectResult { filesChanged: string[] testStatus: string // All passing | X failing | Pending driftFindings: string[] // from validate skill constitutionFindings?: string[] // from validate constitution mode blockers?: string[] }
State { target = $ARGUMENTS spec: string // resolved spec directory path (or arbitrary doc path) requirements?: string // path to requirements.md if present solution?: string // path to solution.md if present contextDocs: string[] // any other relevant docs (refactor briefs, bug reports) units: DeliveryUnit[] mode: Standard | Agent Team result: DirectResult }
Constraints
Always:
- Delegate ALL implementation to specialist subagents — never edit code directly.
- Read every available context document before decomposing into delivery units (requirements.md, solution.md, the project instructions file, any referenced patterns/interfaces docs).
- Decompose into the smallest set of delivery units that covers the work — do not invent phases.
- Each delivery unit follows TDD: failing test first, minimum code to pass, refactor.
- Use the validate skill in drift mode after delegation completes.
- Use the validate skill in constitution mode if a CONSTITUTION.md exists at the project root.
- Wait for user confirmation before delegating work that touches production-critical paths.
- Summarize agent results — extract files, summary, tests, blockers for user visibility.
What ships with it
10 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.

implement-direct is a skill published in the GitHub repository rsmdt/the-startup (510 stars, last pushed 29d ago), licensed MIT. It adds 39 tokens to every session and 1,408 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 2026-08-30.
