These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

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.

Security

Grade A, and why

upskill 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.

Upskill


Overview

/upskill analyses jobs you have tracked and your current profile to identify skill gaps, then produces a heatmap of those gaps and a learning plan with concrete, web-searched study resources and a recommended study order.

Invocation

  • /upskill — aggregate mode: analyses all jobs in job_search_tracker.csv
  • /upskill <URL> — targeted mode: analyses a single job posting fetched from the URL

Step 1: Detect Mode

Check whether the user provided a URL argument:

  • If the invocation was /upskill with no argument → aggregate mode
  • If the invocation was /upskill <URL>targeted mode, store the URL for Step 2

In targeted mode, derive a slug from the job title and company for the report filename (e.g. guardsix-senior-ai-engineer). You will fetch the posting in Step 2.

Step 2: Load Data

Aggregate mode

  1. Read job_search_tracker.csv. Extract all rows. The columns are: date, company, sector, role, role_type, channel, status, contact_person, fit_rating, notes, cv_file, cover_letter_file, source
  2. For each row, note the role, company, and fit_rating. The fit_rating column is a 0–100 score where 100 = perfect fit. You will use it to weight gaps — a lower fit rating means the role exposed more gaps.
  3. Read .claude/skills/job-application-assistant/01-candidate-profile.md to get the candidate's current skills and experience.
  4. Check upskill/ for the most recent aggregate report file (report-YYYY-MM-DD.md) — if one exists, note its date and load it for the diff in Step 8.

Targeted mode

  1. Use WebFetch to retrieve the job posting from the URL.
  2. Extract: job title, company, required skills, preferred skills, responsibilities, and any domain context.
  3. Read .claude/skills/job-application-assistant/01-candidate-profile.md for the candidate's current skills.
  4. No tracker data is used in targeted mode.

Step 3: Pass 1 — Hard Skill Diff

Extract required and preferred technical skills from each job source:

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.
