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.

What it costs to keep this loaded
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 | $0.00020 | $0.00394 |
| Opus 5 | $0.00010 | $0.00197 |
| Sonnet 5 | $0.00004 | $0.00079 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
resume-writing 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.
What it actually says
Resume Writing
Craft resumes that pass ATS filters and impress human reviewers.
ATS Optimization
Must-Do
- Use standard section headings: Experience, Education, Skills
- No tables, columns, or graphics in the main content
- Save as .docx (preferred) or plain PDF (not scanned)
- Use standard fonts: Arial, Calibri, Helvetica
- Include keywords from the job description verbatim
Avoid
- Headers/footers (ATS may miss content there)
- Icons, logos, or images
- Text boxes or floating elements
- Fancy formatting (templates with sidebars often fail ATS)
Achievement Frameworks
STAR (Situation, Task, Action, Result)
Situation: Legacy system had 15s page load times
Task: Reduce to <2s for ecommerce conversion
Action: Implemented CDN caching, lazy loading, DB indexing
Result: Page load reduced to 1.2s, conversion up 23%
CAR (Challenge, Action, Result) — shorter variant
Challenge: 40% customer churn in first 90 days
Action: Built onboarding sequence with 5 touchpoints and milestone tracking
Result: Churn reduced to 12%, NPS improved from 32 to 64
Formatting Rules
- One page for <10 years experience, two pages max for senior
- Bullet points: 4-6 per role, 1-2 lines each
- Quantify everything: %, $, time saved, scale
- Present tense for current role, past tense for previous
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.
