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 | $0.00058 | $0.00884 |
| Opus 5 | $0.00029 | $0.00442 |
| Sonnet 5 | $0.00012 | $0.00177 |
| Haiku 4.5 | $0.00006 | $0.00088 |
Grade A, and why
add-source 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 4d 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Extract structured experience units from a source document and merge them into the user's ExperienceLibrary.
Workflow
1. Identify the source document
If the user has provided a file path or uploaded a document — use it directly.
If no document is in context, ask:
"Which file should I add? Provide the path or paste the content directly."
Supported formats: PDF, DOCX, TXT, MD, plain text paste.
2. Read the current ExperienceLibrary
Read {user_dir}/CareerNavigator/ExperienceLibrary.json. Note:
- Existing unit IDs (to avoid collisions)
- Existing companies and roles (to detect duplicates)
If the file does not exist, create it with an empty units array before proceeding.
3. Extract experience units
Read the source document in full. For each distinct role, education entry, publication, award, or recognition, extract a structured unit:
{
"id": "exp-{next_available_number}",
"type": "role",
"company": "...",
"title": "...",
"dates": "...",
"summary": "1–2 sentence description of scope and context",
"achievements": [
{
"id": "exp-{n}-a1",
"theme": "impact | leadership | technical | commercial | operational",
"text": "exact achievement text, preserved from source"
}
],
"skills": ["skill1", "skill2"],
"performance_weight": 0.5,
"source_document": "{filename of source}"
}
Extraction rules:
- Preserve achievement text as written — do not rephrase or improve at ingest time. Tailoring happens at resume assembly.
- Assign a
themeto each achievement based on what it primarily demonstrates. - Extract skills as they appear — normalize capitalization but do not rename or merge technologies.
- Set
performance_weightto 0.5 (neutral) for all new units. The analyst agent adjusts weights from outcomes.
4. Check for duplicates
Before appending, check each extracted unit against existing ExperienceLibrary entries:
- Same company + overlapping date range = likely duplicate
- If a likely duplicate is found, surface it:
"I see an existing entry for {Role} at {Company} ({dates}) in your ExperienceLibrary. Should I replace it, merge the achievements, or add this as a separate entry?"
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.

add-source is a skill published in the GitHub repository tmargolis/career-navigator (14 stars, last pushed 6d ago), licensed Apache-2.0. It adds 58 tokens to every session and 884 once invoked, about $0.0003 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.
