What it does

Iss Tracker is an agent skill from mohitagw15856/pm-claude-skills. Track the International Space Station live with keyless curl — where it is right now, what it's over, and when to look up, with the orbital math translated into human terms. Use when asked where is the ISS right now, is the space station overhead, when can I see the ISS tonight, or track the station for the kids. Produces the live position translated to a place name, the overhead-math explained, the visibility rules of thumb, and the rerunnable command — the library's proof that live data can also just be…

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.

When your agent uses it

  • Asked where is the ISS right now
  • Is the space station overhead
  • Can I see the ISS tonight
  • Track the station for the kids

Example prompts

  • “/iss-tracker”

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.open-notify.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Iss Tracker loads about 1.3k tokens when it runs. Until then it costs about 134 tokens; SKILL.md has 694 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~134
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Track the International Space Station live with keyless curl — where it is right now, what it's over, and when to look up, with the orbital math translated into human terms. Use when asked where is the ISS right now, is the space station overhead, when can I see the ISS tonight, or track the station for the kids. Produces the live position translated to a place name, the overhead-math explained, the visibility rules of thumb, and the rerunnable command — the library's proof that live data can also just be delightful.

ISS Tracker Skill

Somewhere over your head, sixteen times a day, a football-field-sized laboratory does 27,600 km/h — and a keyless API tells you exactly where it is this second. This skill fetches the position and does the translation that makes it land: raw coordinates become "over the South Pacific, heading northeast toward Chile," and the when-can-I-see-it question gets the honest two-part answer (the rules of thumb that always hold, plus the pointer to precise pass predictions, which need more than an anonymous curl). It's the library's purest fun skill, and it behaves like one — while keeping every number real.

What This Skill Produces

  • The position, translated — coordinates → the ocean/country/region it's over, with direction of travel
  • The astronaut answer — how high, how fast, how often it orbits — the numbers people actually retell
  • The visibility read — the rules for seeing it (and why "right overhead" ≠ "visible"), with the route to precise pass times
  • The command — exact curl, rerunnable — and delightful to hand to a kid

Required Inputs

Ask for these if not provided:

  • Nothing, for "where is it" — that's the beauty; fetch and answer
  • A location, for "is it near me / when can I see it" — city or lat/lon, for the distance math and the visibility read
  • The audience — a curious adult and a seven-year-old deserve different sentences; this skill calibrates joyfully either way

Framework: The Fetch and the Translation

  1. The call: curl -s "http://api.open-notify.org/iss-now.json" → iss_position.latitude/longitude + timestamp. A second fetch ~30 seconds later gives direction of travel from the delta — worth doing; "heading northeast" is half the story's life. (wheretheiss.at's richer API — altitude, velocity per call — is the fallback/enrichment when reachable.)
  2. Translate coordinates or say why not: the lat/lon maps to a named place (ocean names count — it's over water ~70% of the time, which is itself a fun fact to deliver); the translation is the product, the raw numbers are the receipt.
  3. The stable facts carry the wonder: ~420 km up · ~27,600 km/h · one orbit every ~92 minutes · 16 sunrises a day for the crew — stated from knowledge, labeled as the stable facts they are (the position is fetched; the altitude class barely changes).
  4. Visibility honesty: seeing it requires (a) the station over-ish your horizon, (b) your sky dark, (c) the station still sunlit — which is why passes cluster after dusk and before dawn. Overhead at 2pm = invisible; overhead at 2am = usually invisible (station's in shadow too). The rules of thumb get taught; precise pass predictions need orbital propagation — point to the standard spotting services by type rather than faking a timetable.
  5. Distance math when a location is given: great-circle distance from user to the ground track, honestly framed ("passing 1,200 km south of you — below your horizon this orbit") — the near-miss answer is still a good answer when it's true.

Output Format

ISS Right Now — [timestamp]

Over [the place], heading [direction] — next up: [what's ahead on the track].

Altitude ~420 km · speed ~27,600 km/h · orbit every ~92 minutes (the crew sees 16 sunrises a day)

[Location given: "[N] km from you — [above/below] your horizon" · the visibility read: tonight's rules of thumb + where precise pass times live]

Source: open-notify.org (position fetched live; orbital constants are stable facts) · rerun: curl -s http://api.open-notify.org/iss-now.json

Quality Checks

  • The position is translated to a named place, direction included when two fetches allow
  • Fetched data and stable facts are labeled as what they are
  • Visibility answers teach the three conditions, never fake a pass time
  • Location-given answers include the horizon verdict, honest either way
  • The tone matches the audience — wonder is in-spec here

Anti-Patterns

  • Do not answer position from memory — it moved 8 km while you read this sentence, which is the point
  • Do not dump raw coordinates as the answer — the translation is the skill
  • Do not invent pass times — rules of thumb yes, timetables need real propagation, say so
  • Do not confuse overhead with visible — the sunlight condition is the teach
  • Do not flatten the fun — this skill is allowed to be delighted; precision and joy aren't rivals

Example Trigger Phrases

  • "Where is the ISS right now?"
  • "Is the space station overhead?"
  • "Can I see the ISS tonight?"
  • "Track the station for the kids."
