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 | $0.00049 | $0.02443 |
| Opus 5 | $0.00024 | $0.01222 |
| Sonnet 5 | $0.00010 | $0.00489 |
| Haiku 4.5 | $0.00005 | $0.00244 |
Grade A, and why
development 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 yesterday.
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 — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Local override: $TIKA_SKILLS_LOCAL/development/LOCAL.md (default ~/.tika-skills),
read after this file, wins on conflict.
Tika Development Skill
Guidelines and checklist for developing against the Apache Tika codebase.
Question the direction, not just the code
Before optimizing a change — yours or a PR's — ask whether it should exist: does it belong in Tika, is the complexity proportional to the need, would config, an existing mechanism, a plugin, or documentation serve the use case more cheaply? Every merged feature is surface the project maintains for decades. Steelman the use case first and question the vehicle, not the goal; pushback must name a concrete cost or a simpler path — never taste alone, and never no for the sake of no. "The direction is right" is a valid conclusion.
Feature whose shape isn't known yet: spike first, cut PRs after
(.skills/devs/feature-workflow/SKILL.md).
Git Policy (default — personally overridable)
Never run git commit or git push — no commits of any kind, including
merge commits. If a merge is needed, use git merge --no-commit --no-ff
and hand back. Stage files and provide the suggested commit message for
the user to run.
Never write to GitHub (PR comments, reviews, issues, labels, merges).
Read-only gh is fine.
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.

development is a skill published in the GitHub repository apache/tika (4,018 stars, last pushed 2d ago), licensed Apache-2.0. It adds 49 tokens to every session and 2,443 once invoked, about $0.0002 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.
Other skills, from other repositories
pr-checklist
Use when opening or finalizing a GitHub PR for OpenMetadata. Walks through the repo PR template — linked issue, high-level design (for big PRs), unit/integration/Playwright tests + coverage, UI screen recording, and manual test steps — then drafts a fully-filled PR body and (optionally) creates the PR.
systematic-debugging
Use when debugging a failing test, build error, or runtime issue that isn't immediately obvious. Guides a 4-phase root cause analysis instead of random fix attempts.
connector-standards
Load all OpenMetadata connector development standards into context. Use before building or reviewing connectors to ensure consistent patterns.
union-type-wrappers
Add typed getters and setters over BinaryData properties that represent TypeSpec union types in generated Java models. Use when generated classes expose BinaryData for union-typed fields and you need ergonomic, type-safe accessors instead.
run-tests
Run project tests using Maven (mvn). Use when the user asks to run tests.
search-m2
Search for Java classes inside Maven dependencies in /.m2. Use when the user asks to locate classes or inspect JARs. Cross-reference pom.xml files in the current directory to resolve dependency names/versions.
