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.

SkillSpector: 2 findings, up to high
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 →
- high Privilege Escalation · line 102 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Agent Snooping · line 339 Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00079 | $0.05729 |
| Opus 5 | $0.00039 | $0.02864 |
| Sonnet 5 | $0.00016 | $0.01146 |
| Haiku 4.5 | $0.00008 | $0.00573 |
Grade A, and why
fulcra-media scanned grade A with 1 finding 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 11d 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.

fulcra-media — Import a user's media history into Fulcra
fulcra-media is a Python CLI that imports media events (watches, listens, books read) into Fulcra as DurationAnnotations. Each import is idempotent (re-runs are safe), and every command supports a --json flag for machine-readable output and a --check-only dry-run.
This skill helps you (the AI agent) run imports on the user's behalf, schedule periodic syncs, and interpret the results.
Runtime-agnostic. Everything below is shell I/O. This skill works the same in Claude Code, OpenCode, Codex, Gemini CLI, Copilot CLI, or any agent runtime that can execute a subprocess. No Claude-Code-specific tools are required — the only contract is fulcra-media on PATH and the JSON envelope schema.
Where to start — the re-entrancy probes
Before running an import, probe how far this user already got. The states are a prefix of the flow —
authed? → defs bootstrapped? → nothing pending? → already synced? — so enter at the first
probe that fails (per the repo's skill-quality pattern, docs/skill-quality-pattern.md). Every
state is safely re-enterable: bootstrap is idempotent, and each import is idempotent (deterministic
source_ids + the watermark layer), so re-probing or re-importing never double-counts. The rows below
consolidate the probe concepts used later in this skill (the --check-only/would_post probe in
"Is there anything new to post?" and the heartbeat contract's "Inspect first / Probe before paying"
steps) into one ordered entry point — see those sections for the fuller treatment.
| Probe (run in order) | Command | Passes when | If it fails, enter at |
|---|---|---|---|
| Authed? | fulcra auth print-access-token |
exits 0 and prints a non-empty token (the CLI mints/refreshes it; FULCRA_ACCESS_TOKEN in the env also satisfies this) |
AUTH — tell the user to run fulcra auth login (interactive browser flow); see "Fulcra Life API auth" below |
| Defs bootstrapped? | fulcra-media status |
the JSON's watched_definition_id / listened_definition_id / read_definition_id are non-null for the category you're importing (Watched for netflix/trakt/youtube/…, Listened for lastfm/deezer/spotify/…, Read for goodreads) |
BOOTSTRAP — run fulcra-media bootstrap (idempotent; no-op once defs exist) |
| Nothing pending? | fulcra-media import <name> --check-only --json then read would_post (file-based importers also take their <path>/URL argument — e.g. netflix, youtube, spotify-extended, spotify-ifttt, apple-takeout, generic-csv take a file path; generic-rss takes a feed URL — so --check-only still needs it) |
would_post: 0 (--check-only skips the POST; costs an API readback but no ingest) |
IMPORT — would_post > 0 means there is new media; run fulcra-media import <name> --json for real |
| Already synced? | fulcra-media status and read watermarks["<name>"] |
the pass-criterion depends on the importer's watermark class (only ISO watermarks are ever WRITTEN — watermarks.py also defines a snapshot shape, but no importer currently calls it): API-poll importers (lastfm, deezer, letterboxd, goodreads, generic-rss) store an ISO 8601 timestamp — pass when it's present and recent (note goodreads and generic-rss key theirs as watermarks["goodreads:<user_id>"] / watermarks["generic-rss:<feed_url>"], not the bare name). Everything else — apple-podcasts, the one-shot GDPR/export uploads (spotify-extended, spotify-ifttt, youtube, apple-takeout, netflix), trakt, and generic-csv — never advances a watermark, so this probe is N/A for them: fall back to the would_post probe above |
IMPORT — ISO watermark cold-start or stale; run the real import to advance it. For the no-watermark importers, re-check via would_post; for the export uploads specifically, re-run only when the user hands you a fresh export |
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.

fulcra-media is a skill published in the GitHub repository ashfulcra/fulcra-tools (10 stars, last pushed yesterday), licensed MIT. It adds 79 tokens to every session and 5,729 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
