What it does
Document Authoring is an agent skill from Sidiora-Labs/centra-gideon-agent. Author a real document — a report, proposal, slide deck, spec, or paper — by settling audience, claim, and structure before drafting prose, then writing to that structure. Use when asked to write or draft a document rather than answer a question.
Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office, covering Slides and decks. The repository describes itself as: The companion AI agent that learns, adapts and gets the work done no matter the task. The licence is Apache-2.0.
When your agent uses it
- Draft a document rather than answer a question
- Tasks that involve Slides and decks
Example prompts
- “/document-authoring”

What it can do on your machine
Read from SKILL.md and the folder at commit ca531ee. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Document Authoring loads about 970 tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 429 words of instructions outside code blocks.
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.

Document authoring
A document that starts as prose becomes a document nobody can edit, because the structure is buried in the sentences. Settle the frame first; the prose is then mechanical.
Settle four things before writing a sentence
- Audience and their decision. Who reads this, and what do they do differently afterwards? "Inform the team" is not a decision. "Approve the migration budget" is. If there is no decision, the document is reference material — say so, and structure it for lookup instead of persuasion.
- The claim. One sentence that could be wrong. If your thesis cannot be disagreed with, you have a topic, not a claim.
- The shape. Pick one and commit:
- Decision memo — claim, options, recommendation, risks, ask.
- Report — question, method, findings, limitations, implications.
- Proposal — problem, cost of inaction, approach, plan, resources.
- Spec — contract, behaviour, edge cases, out of scope.
- Deck — one idea per slide, headline is the takeaway not the topic.
- The evidence you actually have. List it before drafting. A structure your evidence cannot fill is where invented specifics come from.
Then draft
- Front-load. Conclusion first. A reader who stops after the first paragraph should still have the answer.
- Headline the takeaway. "Latency regressed 40% after the cache change" beats "Latency analysis". This applies to every section heading and every slide title.
- One idea per unit — per paragraph, per slide, per bullet.
- Name the limitations in the document, not in a follow-up conversation. An unstated limitation reads as a claim you did not make.
- Cut the frame. "This document will discuss…" and "In conclusion…" are scaffolding. Remove them once the structure holds on its own.

Slides differ from prose
A slide is a visual argument. If a slide needs a paragraph, it is two slides or it belongs in an appendix. Speaker notes carry the nuance; the slide carries the claim and the one piece of evidence that supports it.
Worked example
Asked for "a document about our test flakiness".
Settling it first:
| Audience / decision | Eng leads — decide whether to fund a two-week stabilization sprint |
| Claim | Flaky tests cost us more engineering time than the sprint would, so the sprint pays back inside a quarter |
| Shape | Decision memo |
| Evidence I have | 6 weeks of CI reruns, 3 named flaky suites, the rerun-minutes total. No per-engineer interruption data — so I will not claim a focus cost |
The resulting skeleton:
Recommendation: fund the two-week stabilization sprint (the ask, first)
What it costs us now: 41 rerun-hours over 6 weeks, concentrated in 3 suites
Why it compounds: a suite people rerun by reflex stops being a signal
The plan: quarantine, root-cause the 3, add a vacuity check to each rail
What I cannot show: per-engineer interruption cost — no data collected
Risk: two weeks not spent on the roadmap; mitigated by taking it after the releaseOnly now write prose, and only to fill that skeleton. Note the fourth row of the table doing real work: it forced a limitation into the document instead of an overclaim into the argument.
