Apache Tika is a toolkit that reads many kinds of files and extracts their text and descriptive metadata, including from formats such as PDF, PowerPoint, and Excel. Applications and agent pipelines use it to turn documents into content they can process, search, or pass to language models. The catalogue skills provide reusable ways for coding agents to run Tika for file-to-Markdown extraction.
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: 1 finding, up to medium
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 →
- medium Data Exfiltration · line 232 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00050 | $0.03294 |
| Opus 5.5 | $0.00020 | $0.01318 |
| Sonnet 5.5 | $0.00010 | $0.00659 |
| Haiku 4.5 | $0.00005 | $0.00329 |
Grade A, and why
tika-eval-compare 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 26d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -o /tmp/tika-app-before.zip <snapshot-url> How it starts
The opening of the file, as written. The whole thing — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Local override: $TIKA_SKILLS_LOCAL/tika-eval-compare/LOCAL.md (default ~/.tika-skills),
read after this file, wins on conflict.
tika-eval: Compare Before/After Extracts
Compare the output of two versions of Tika against a corpus of files to detect regressions in content extraction, encoding, exceptions, and embedded document handling.
Before You Start
Ask the user for:
- Working directory — where to put builds, extracts, eval db, and
reports (
<workdir>below). All artifacts go here. - Number of threads (
-n) — default is 2. Use-n 6for faster runs when parse time comparison is not needed. When comparing parse times between A and B, use the same-nfor both. - Run reports? — whether to auto-generate the HTML/Excel reports
and
summary.mdat the end (the-rflag on tika-eval Compare).
Prerequisites
- Two tika-app builds (a "before" and an "after"), each as an unzipped
zip archive containing
tika-app-*.jar,lib/, andplugins/. - A corpus of input files (a directory tree).
- tika-eval-app, built from
tika-eval/tika-eval-app(use the zip). The baretarget/tika-eval-app-*.jaris thin (no bundled deps) and dies withNoClassDefFoundError: ...GzipCompressorOutputStream(esp. with-r). Always run the jar from the unzippedtarget/*.zipdir, which carries itslib/. - Enable MD5 digesting in both configs so tika-eval can match
embedded documents by content hash (not just index position).
Add to the config JSON:
Note:"parse-context": { "commons-digester-factory": { "digests": [ { "algorithm": "MD5" } ] } }parse-contextis a JSON object, not an array.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tika-eval-compare is a skill published in the GitHub repository apache/tika (4,099 stars, last pushed today), licensed Apache-2.0. It adds 50 tokens to every session and 3,294 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
