development

Development rules for Apache Tika, a project that extracts text and metadata from files. They cover Git, Maven, code, tests, and checks before changes are submitted.

In plain words
What is it for?
Planning Tika changes, choosing between code and simpler alternatives, building and testing modules, and preparing changes without committing or pushing them.
Why use it?
They reduce mistakes when changing a large shared codebase and help keep contributions consistent with the project's long-term needs.

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.

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

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.
